Never in the past had I raised such a question What is the difference between a cleaner and disinfectant?”and i’m sure you would have also not thought much about it.It was when disinfection was recommended for keeping covid -19 virus at bay that i encountered the usage of the word at a domestic level .All these days i was happy that i had kept things around me clean and avoided falling ill. So what was i actually doing by cleaning ?Several questions flashed in my mind and started looking for answers. I have compiled them to share it with you, as it would be of use to all.What is cleaning?By definition it is the process by which dust, infectious agents and unwanted materials are removed to keep surfaces clean. Here again infectious material removal happens if soap is used and the cloth used for wiping is effectively able to hold the germs, else only dirt or dust is removed leaving behind germs to survive.What is a disinfectant, does it kill micro organisms?A non toxic disinfectant kills micro organisms like fungi, bacteria and virus which are present on hard /non porous surfaces.How does a disinfectant kill micro organisms?There are two mechanisms by which micro organisms are killed1. Destruction of cell wall.2. Hindering the metabolism of the organism.Are disinfectants chemicals?Yes, they are chemicals. Biodegradable and eco-friendly disinfectant cleaner are also available which are better alternatives.Is using disinfectant safe?Use of disinfectants within the advised limit with the prescribed precautions should not have issues. But using chlorinated disinfectants like hypo at frequent intervals damages the mucous membrane, its highly irritable.Can we use disinfectant on dirty surfaces?No, disinfectants are not effective in killing germs when the surface to be treated has dust or substances like oil grease, food particles etc. on it.Having got a clear picture on the difference between cleaning and disinfection, my attention turned to digging deep into disinfectants.Why disinfection is important? There is a lot of stress on it,can we go without it ?With the prevailing pandemic situation every thing around has to be disinfected to keep away the virus. Going without it would be risky at this point of time specially where the movement of people is high. Common touch points need special attention, common areas like walk ways, storage areas also need disinfection.Conclusion: Cleaning removes only visible dirt but disinfection removes (kills) micro-organisms.There are a lot of places that need to be cleaned and then disinfected, at almost frequent intervals to keep away germs. As there is an increase in the frequency of disinfection the need to use a safe disinfect is a mandate.
1.Introduction to silicone acrylic emulsionSilicon-acrylic emulsion is a kind of composite emulsion. It is a copolymer emulsion of organosilicone and acrylate.Acrylic resin has many excellent characteristics, such as weather resistance and light resistance, long time under ultraviolet irradiation is not easy to yellow. In addition, it also has flexibility, so it is often used as a leather finishing agent. However, as acrylic resin belongs to thermoplastic materials, it is a linear molecular structure, lack of crosslink points, not easy to form a network structure, sensitive to temperature changes, high temperature return viscosity, low temperature lack of elastic, that is, easy to appear hot viscosity cold brittle phenomenon.The main chain of organosilicon resin is si-o bond, and its bond energy is 450k J/mol, which is much higher than the bond energy of 345kJ/mol of c-c bond and bond energy of 351kJ/mol of c-o bond. Therefore, organosilicon resin has good resistance to high temperature, infrared radiation and ultraviolet light, chemical resistance；In addition, the surface energy of organosilicon resin and low vitrification temperature are low.With good hydrophobic wear resistance and anti - pollution.In summary, the modification of acrylic resin with an appropriate amount of silicone resin can not only make up for the defects of acrylate, but also improve its mechanical properties.2.Modification method of silicon - acrylic emulsionSilicone acrylic emulsion modified method there are two ways: the physical method is to a certain amount of siloxane and acrylate mechanical mixing, this method is simple, but due to both the surface and the difference of molecular structure, poor compatibility with polysiloxane acrylate, because the former is migration, caused by composite emulsion stability is poor, prone to phase separation phenomenon, the result is not ideal.Chemical method is the use of emulsion polymerization, in addition to the siloxane and acrylate have a simple physical cross-linking, but also the existence of chemical bonds, so that the two components of the polarity of the material with a large difference in the combination, in the micro to achieve uniform dispersion, improve the stability of the emulsion.The silicon-propylene composite emulsion was prepared by chemical method, and then the silicon-propylene composite emulsion was used to replace the water-borne polyurethane emulsion.The modified waterborne polyurethane emulsion has the advantages of three, and the water resistance is improved.According to the preparation method of si-acrylic emulsion, si-acrylic emulsion was prepared by seed emulsion polymerization with methyl methacrylate acrylic vinyl silicone oil as raw material.Then the prepared silicon-acrylic emulsion was modified to the prepared waterborne polyurethane, the composite emulsion was configured by blending method, the film was formed on different substrates, and the mechanical properties of the film such as adhesion contact Angle water absorption were tested,The film surface of the modified si-acrylic emulsion /WPU composite was observed by scanning electron microscope.The structure was analyzed by ir spectra.The experimental results show that the water absorption rate is the lowest when the content of si-propylene emulsion is 2%, which is 18.19%.The adhesion reaches a level when the content is 4% and 5%.Viscosity is also lower than before modification.

At present, two-component waterborne polyurethane has been widely used in leather, textile dyeing AIDS, adhesives, foam materials, coatings and other fields. With the continuous development of two-component waterborne polyurethane scientific research, it is gradually replacing solvent polyurethane as the medium to occupy the dominant position in the market.One: leatherChina's leather resources, production and export trade are among the world's leading.China's annual consumption of polyurethane synthetic leather paste is nearly 2.4 million tons. The solvent polyurethane used in the synthetic leather industry has caused serious environmental pollution, and the production process of water-based synthetic leather cleaning emerged as The Times require.At present in the leather industry, waterborne polyurethane is mainly used for leather finishing, leather filling, leather adhesive and so on.In synthetic leather, the dispersed two-component waterborne polyurethane can be used as adhesive for artificial leather and surface treatment agent for artificial leather, as well as for synthetic leather bass, surface layer resin, bass veneer and special base coating resin.Two :Textile dyeing auxiliariesIn the field of textile industry, two-component waterborne polyurethane can be used as dyeing AIDS, printing, finishing agents, etc., showing good application properties, such as flame retardant, breathable, wrinkle resistance, etc.Fabric finishing agent is a layer of coating on the surface of the fabric, on the one hand, the surface gives the fabric some functions, such as waterproof, fire, etc.On the other hand, different fabric finishing agents give fabrics different appearance styles.Traditional solvent - based two - component polyurethane system contains a large number of organic solvents, causing great harm to human body.The two-component waterborne polyurethane system is free from harmful solvents such as formic acid, which may be the development direction of textile dyeing auxilaries in the future.Three : AdhesiveNational standard GB/ t30779-2014 waterborne polyurethane adhesive for shoes was officially implemented.This standard has filled the gap in the field of waterborne polyurethane adhesive for shoes in China, further standardizing the market order of waterborne polyurethane adhesive for shoes, and has a good promoting effect on environmental protection and energy saving in the production of shoes.Two-component waterborne polyurethane adhesive is widely used in the fields of soles and uppers, leather, home building materials, automotive interior and so on, but there are serious safety, health and environmental protection problems in the production and application of solvent adhesive.With the promotion of national policies and the continuous enhancement of enterprise customers' concepts of safety, green and environmental protection, it has become a trend to vigorously research and develop environmentally friendly adhesives with high technical content, high added value and high performance.The two-component waterborne polyurethane adhesive has the characteristics of high adhesion strength and wide application range.The bonding technology between the soft and hard substrates has high requirements on the bonding strength, heat resistance, weather resistance, water resistance, chemical resistance and other comprehensive properties of the adhesive.Two - component waterborne polyurethane has been widely used to meet the requirements of adhesive property.Four: foam materialTwo - component waterborne polyurethane also has important applications in foam industry.WPU foam can be used to repair the cement cement road.WPU foam material can be foamed and solidified quickly, and it has high compressive strength, realizing quick repair of road surface and saving cost.In order to increase the bonding force between WPU foam material and the substrate, the epoxy resin was used to modify WPU foam material, and the dihexanolamine was used to react with the epoxy resin to open the ring, which improved the interfacial bonding force of the foam material.Five:the coatingTwo-component waterborne polyurethane coatings with good performance and low VOC content have broad application prospects.The coating with smooth surface, high gloss and good performance can be obtained by combining polyol component with aliphatic polyisocyanate curing agent.In the future, it will replace solvent - based two - component polyurethane to become the leader of coating industry.A two-component waterborne polyurethane coating with high gloss, high drying rate, good weather resistance and low cost was prepared by using acrylic polyol dispersion as film forming agent, waterborne HDI trimer as curing agent, iron white powder as pigment, and suitable additives.In addition to the above applications, two-component waterborne polyurethane can also be used in antibacterial materials, hydrogels, etc.Through multifunctional modified polyurethane can also be applied in antibacterial material, using the epoxy propyl alcohol isocyanate polyurethane pre polymers to end sealing side, the waterborne polyurethane molecular chain containing epoxy groups, by Fielding diamine crosslinking agent with an antibacterial compound with epoxy quaternary ammonium compounds, the preparation of compound can be used for wound dressing, can effectively absorb wound exudate.Dopamine-modified waterborne polyurethane was combined with FE 3O4 nanoparticles to prepare nanocomposites, which were applied to biomimetic hydrogels.
