Coating general knowledge: which coating base materials are suitable for oxidative polymerization dry coating

It is suggested that the oxide polymerized coating can be formed by the reaction of film-forming substance in the coating and oxygen oxidation polymerization in the atmosphere when the solvent or dispersion medium volatilizes Metal soap with organic acid can accelerate the drying process The metal soaps of this kind of organic acids are called driers Long chain fatty acids (esters) increase the relative molecular weight through oxidation, and reach oxidative polymerization and dry-junction In the coating industry, grease is rarely used as the only film-forming substance, and it is generally combined with other resins, such as the resin of the sheet and the phenolic resin to make oil-based resin paint or varnish Although alkyd resins are not necessarily made from plants Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating home news: the oxidation polymerization coating in the solvent or dispersion medium volatilization at the same time, through the coating of film-forming substances and the atmosphere of oxygen oxidation polymerization reaction curing film Metal soap with organic acid can accelerate the drying process The metal soaps of this kind of organic acids are called driers Long chain fatty acids (esters) increase the relative molecular weight through oxidation, and reach oxidative polymerization and dry-junction In the coating industry, grease is rarely used as the only film-forming material, and is usually combined with other resins, such as Celine resin and phenolic resin to make oily resin paint or varnish Although alkyd resin is not made by the reaction of vegetable oil and polyol, the mechanism of polymerization is the same Long oil alkyd resin, which is soluble in short fat solvent, is widely used in air dry decorative coatings because of its good glossiness, light rotation, weather resistance and easy to brush At the same time, long oil alkyd resin can also be used in outdoor alkyd paint (steel structure paint, construction paint) as the main film-forming material In addition, alkyd resin can also be modified to form a new alkyd resin, mainly the adjustment of fatty acid type and oil degree, so that the comprehensive performance (drying speed, solubility, polymerization degree and compatibility with other resins) of the modified alkyd resin can be significantly improved Many air drying industrial coatings (such as those used for surface coating of heavy agricultural machinery) are made of styrene or vinyl toluene modified medium short oil alkyd resin as paint base with aromatic solvent The film was formed by oxidative polymerization and solvent evaporation If it is heated to 60-80 ° C, the drying speed can be obviously accelerated 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,
