Coating technology: production technology of granite paint

Core tip: water in water multi-color coating is a kind of coating that can get colorful patterns by using water as solvent or dispersing medium It is a kind of environmental protection building coating that can not only meet the requirements of environmental protection and energy conservation, but also give people a sense of elegance, grandeur and diversity, novel and potential, and meet the future development direction of the coating The following is a brief introduction of water in water multi-color Coating - production process of granite paint (1) Preparation of 5% protective glue solution of granite paint: The ratio of raw materials and weight is Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: water in water multi-color paint is a kind of paint that uses water as a solvent or as a dispersing medium, and can get color patterns once applied It is not only in line with environmental protection and energy saving It is required to give people a sense of elegance, grandeur and variety It is a new and potential environment-friendly architectural coating, which is in line with the future development direction of the coating Here is a brief introduction to the production process of water in water multicolor coating granite paint (1) Preparation of protective glue solution with 5% concentration of granite paint: the raw material and weight ratio are 95 parts of water, 5 parts of Sinoma PG, 0.25-0.5 parts of sodium pyrophosphate First, add water into the mixing drum according to the above weight, then add sodium pyrophosphate, stir to make the solution uniform, then slowly add Sinoma PG, control the rotation speed of 800-1200 rpm, and disperse at high speed for 15-20min to prepare sandstone paint; (2) preparation of white base paint of granite paint: The ratio of raw material and weight is 25-35 parts of water, 5-10 dehydrated silica oil, 600-1000 water washed kaolin, 25-30 parts 600-1000 heavy calcium carbonate, 0.3-0.5 hydroxyethyl cellulose, 0.15-0.20 polyacrylic acid ammonium salt, 0.45-0.75 alkylphenol polyoxyethylene ether, 25-35 pure acrylic elastic emulsion, 0.10 0.15 parts AMP-95 and 5-10 parts from 0.1-0.3 (1) The prepared 5% concentration protective glue solution is first added with water according to the above weight in the mixing tank, then added with hydroxyethyl cellulose, stirred to full solution, then added with dispersant ammonium polyacrylate, alkylphenol polyoxyethylene ether, silicone oil, stirred at 200-400r / min speed for 5min to make it uniform, then added with powder, namely, washed kaolin and heavy calcium carbonate, and dispersed at high speed for 30min at 800-1200r / min speed The size of the paint is 30 micron m, plus acrylic elastic emulsion, speed 200-400r/min stirring 5-10min, finally add 5% protection glue solution, stir evenly, reserve (3) color matching of granite paint: according to the design requirements, use the white base paint prepared in step (2) of 100 parts by weight to mix with 0.1-1.0 parts of color paste, stir the old-fashioned paint evenly, and mix it into a color base paint, and use different monochrome, mixed color or multi-color to match each color base paint according to the above proportion; (4) granulation of granite paint The raw material and weight portion ratio is 20-30 parts of 1 concentration protection glue solution prepared by step (1), 40-50 color basic paint, 25-30 organosilicon grafted pure acrylic emulsion, and 1.5-3.0 ethylene glycol mono butyl ether film-forming auxiliaries First, the mixture of silicone acrylic emulsion and ethylene glycol mono butyl ether is mixed evenly, and then the concentration of the relevant color basic paint is screened into 5% concentration respectively In the protective glue solution, the mesh is 5-20 mesh, and then the spare material prepared in this step is mixed, and the coating is cost-effective if it is stirred evenly In the later stage, the viscosity has obvious thickening phenomenon, so a certain amount of sodium pyrophosphate needs to be added 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,
