Coating classification: waterborne alkyd paint

Core tip: vegetable oil is alcoholysis and then reacts with anhydride to form alkyd resin, increasing the content of hydrophilic group can be made into water-soluble or water dispersible resin The water-soluble water-soluble alkyd is quite transparent, but has color, and alkyd emulsion is brown yellow opaque Unsaturated bond in alkyd resin molecule is the basic guarantee of excellent performance of paint film As the solvent alkyd paint, the performance of the coating can be adjusted by the length of the oil, which is short in oil, fast in drying, high in gloss, high in film hardness, long in oil, good in flexibility and impact resistance Therefore, waterborne alkyd paint also has short oil degree and long oil degree Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of paint: vegetable oil is alcoholysis and then react with anhydride to form alkyd resin, increasing the content of hydrophilic group can be made into water-soluble or water dispersible resin The water-soluble water-soluble alkyd is quite transparent, but has color, and alkyd emulsion is brown yellow opaque Unsaturated bond in alkyd resin molecule is the basic guarantee of excellent performance of paint film As the solvent alkyd paint, the performance of the coating can be adjusted by the length of the oil, which is short in oil, fast in drying, high in gloss, high in film hardness, long in oil, good in flexibility and impact resistance Therefore, waterborne alkyd paint also has short oil degree and long oil degree Alkyd resin has good permeability in wood, especially suitable for making water-borne colorant Another advantage of waterborne alkyd paint is that it is cured by oxygen in the air, so the solvent resistance of the paint film is much better than other single component waterborne coatings Acrylic modified waterborne alkyd paint is a kind of alkyd paint which is added with acrylic monomers during alkyd synthesis The light retention of modified alkyd resin is improved significantly Recently, in order to further improve the performance of waterborne alkyd paint, the alkyd / acrylic hybrid technology has been developed to make the core-shell system with alkyd polymer as the core and acrylic polymer as the shell The hydrophilic acrylic shell protects the alkyd core from hydrolysis After painting, the water in the paint evaporates, and the emulsion particles penetrate into the micropores of the wood The linear polymer molecules are then oxidized to form a membrane Waterborne urethane oil is alkyd resin modified by diisocyanate Diisocyanate reacts with hydroxyl group of alkyd resin to form polyurethane structure, which has some properties of polyurethane and retains the characteristics of oxidation and cross-linking of alkyd resin The one component water-based coating is easy to construct and has excellent performance, and is one of the excellent varieties of water-based coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
