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.
1.The cause of a back adhesion：(1)the paste itself anti-viscosity, especially in the wet weather easy to stick back;(2)After the printing is completed, it is packaged without perfect heat treatment;(3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion;(4)transport or storage conditions are not good, in high temperature, high humidity conditions for a long time stack.Treatment methods for back adhesion:(1)choose good anti - sticky paste printing;(2)Good heat treatment for printing products;(3)Pay attention to the mixing formula, if the transparent pulp more than 80% is easy to cause back adhesion, so you can add an appropriate amount of curing agent or anti-adhesion agent for treatment;(4)Please pay attention to the improvement of transportation and storage conditions.(5)with anti - stick items to strengthen the whole processing.2.Reasons for poor elasticity：(1)The selection of sizing technology and printing fabric do not match;(2)After printing drying treatment is not complete;(3)too much crosslinking agent will affect the size of the elasticity and softness.(4)add excessive destruction of resin tensile material (urea, ammonia).3.Causes of color transfer phenomenon:(1)when mixing the selection of color species poor resistance to migration;(2)add excessive color species;(3)printing products dry processing;(4)transport or storage conditions are not good, in high temperature, high humidity conditions for a long time stack.Treatment of color transfer phenomenon:(1)selection of good color species resistant to migration to adjust the paste.(2)Good heat treatment for printing products;(3)In transportation and storage, as far as possible flat, do not fold together or with insulation paper.

Introduction and application field of waterborne polyurethane waterproof coating2020-01-11Environmentally friendly water-based polyurethane waterproof coating is two-component,The component A is an isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanate, and the component B is a colored liquid composed of a plasticizer, a curing agent, a thickener, a coagulant, and a filler.After use, the two components of methyl and ethyl are evenly mixed according to the ratio, and they are painted on the surface of the waterproof base layer, and a chemical reaction occurs, which penetrates into the pores inside the base material and fuses with the base material to form a layer of crystalline and dense waterproof. The anti-corrosion layer closes the water passage and infiltration, and achieves waterproof and anti-corrosion effects.Polyurethane resin can be used to increase the carcass reinforcement treatment in areas where flooding, expansion joints, culverts, etc. are extremely important or require special treatment. After completion, it can be used as a protective layer or other covering layer.If the base surface is too dry, it can be sprayed with water to moist and no clear water. After spraying, it will be more effective after curing.Applicable to national key projects and general waterproofing projects, such as roofing, colored steel tiles, balconies, basements, civil air defense works, kitchens and bathrooms, culverts, tunnels, bridges, pools and other projects. Anti-corrosion of tunnels and other projects, and bonding of wooden floors, cement boards, asbestos products, glass steel products, ceramic products, floor tiles, etc., can also be used for caulking materials of building structures, floor heating, porcelain tiles and cement flooring And floor professional waterproof treatmen
