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.
The choice of solventIn the printing ink manufacturing process, in consideration of the overall solvent system of the ink volatility, to improve the printing ink solvent release and reduce the solvent organic solvent residue, the use of solvents are often several volatile mixed solvents.In the printing ink manufacturing process, the main organic solvents are toluene, butanone, cyclohexanone, ethyl acetate, butyl acetate, n-propyl acetate, isopropanol, etc., customers can adjust the volatility of the ink according to seasonal changes.The choice of pigmentAs a result of the market pigment grade difference, in polyurethane ink for the same resin manufacturers of the same pigment dispersion, ink stability and other aspects of the performance is often a big difference, so it is recommended that users according to their actual customer needs carefully choose pigment.The selection of additivesWax powder: in the production of polyurethane ink, the use of wax powder is often low molecular weight polyethylene wax, the relative molecular weight is generally 1000 ~ 6000, the organic solvent in the ink has a good solubility, and polyurethane resin affinity is good, at the same time has a good chemical stability.Mainly to increase the friction of the surface of the ink film, at the same time to properly alleviate the anti-viscosity of the ink itself.Dispersant: a class of surfactant, mainly used for wetting pigment surface, shorten ink manufacturing time, is conducive to the dispersion of pigment, and sometimes appropriate to reduce the oil absorption of pigment.In the production of high concentration of ink, ink yield can be reduced to prevent the ink pigment particles agglutination and precipitation has a certain effect.Polyurethane resin adhesion promoter: printing inks containing a large number of polar groups, BOPP, PE and so on nonpolar substrate surface even by corona surface treatment, surface tension in 38 dyne ~ 42 dyne, to improve the polyurethane ink on the substrate surface adhesion fastness, often need to add the appropriate ester titanate coupling agent or chlorinated polypropylene adhesion promoter.
One, extinction principleGeneral can be divided into physical extinction and chemical extinction.Physical matting, is the addition of matting agent, so that the coating in the film when the uneven surface, reduce reflection and achieve low gloss.Two, the kind of matting agentCoating common matting agent can be divided into organic matting agent and inorganic matting agent two categories.1.Organic matting agentMetal soap was a matting agent commonly used in early times, mainly some metal stearates, such as aluminum stearate, calcium stearate and magnesium stearate.Among them, aluminum stearate is used most.The extinction principle of metal soap is based on its incompatibility with coating components, suspended in the coating, film formation is distributed on the surface of the film, resulting in micro roughness, reduce the reflection of the film surface light to achieve extinction purposes.The disadvantage is that the polarity of the water-based resin is too different, it is difficult to disperse in the water-based system.Wax is an earlier and more widely used matting agent, coating film with the solvent volatilization, wax precipitation, with fine grains suspended in the film surface, resulting in increased scattering and matting effect.Wax as a matting agent is characterized by easy to use, and the film has a good handle and resistance to water, moisture and heat.However, the formation of wax layer will also prevent the solvent volatilization and oxygen infiltration, affecting the drying and coating film.At the same time in the water-borne resin dispersion is poor, poor compatibility, easy to demulsify or gel.Tung oil can also be used as a matting agent in the paint, the main use of tung oil in the high reactivity of the conjugate double bond, contact paint film of different medium surface: substrate and air oxidation crosslinking speed is different, so that the film surface become uneven and achieve matting effect.2.Inorganic matting agentDiatomaceous earth, kaolinite, talcum powder and silicon dioxide are the functional fine materials used as extinction agent.When the film is dry, their tiny particles will form a micro-rough surface on the film surface, reducing the reflection of light to obtain a matte appearance.The matting effect of this kind of matting agent is restricted by many factors, the disadvantage is that the addition of matting agent reduces the coating's water resistance and alcohol resistance, the transparency of the varnish has a greater impact, can not be a good display of the surface texture of the coated object.
