Coating technology: the process of oil color agent configuration

Core tips: the colorant is a common raw material in the production process of wood paint The oil colorant is used for coloring wood paint It has the basic performance of traditional wiping colorant, and has the following advantages: the oil colorant has strong thixotropy, good storage stability, is not easy to precipitate and layer, and has strong adhesion; According to the choice of pigment and dyestuff, the color type, depth and brightness can be achieved The selection is flexible and can be applied to a wide range of coatings Configuration example of oily colorant for black brown wiping: The oily colorant for black brown wiping, in weight percentage, is mainly composed of the following raw material groups 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 Paint Home News: colorant is a commonly used raw material in the production process of wood paint Oily colorant is used for wood paint coloring It has the basic performance of traditional wipe colorant, and has the following advantages: oily colorant has strong thixotropy, good storage stability, is not easy to precipitate and layer, and has strong adhesion; its color type, depth and brightness can be based on the pigment And the selection of dye can be achieved, the selection is flexible, and the range of application in paint is wide Example of oil colorant configuration for black brown wipe: Oil colorant for black brown wipe is mainly composed of the following raw materials by weight percentage: short oil resin 15% thixotropic resin 15% s-10015% byk1062% black brown powder (AMBA color powder) 25% Filler 28% total 100% The short oil resin is alkyd resin, and the technical requirements are: weight solid content is 70 ± 1%, acid value ≤ 8.6mg KOH / g, Gardner Color ≤ 4 The thixotropic resin is alkyd resin, and the technical requirements are: the weight solid content is 60 ± 2%, the acid value (according to the solid content) is ≤ 25mg KOH / g, the Gardner chroma (50% dissolved in xylene) is ≤ 10, and the resin content is ≈ 7% The filler is aromatic solvent S-100 The specific production process is as follows: firstly, the short oil resin, thixotropic resin and aromatic solvent S-100 are weighed well, added into the container, stirred evenly, and added with wetting dispersant; secondly, the pigment is slowly added into the mixing to disperse at high speed; finally, the fineness is grinded to be qualified The test results of the oily colorant for the black brown wiping are as follows: solid content is 43.3% GB / T 1725-79 (method B); appearance: Black Brown opaque semi fluid GB 1727-79 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,
