Water based paint production process related information

The basic production process of waterborne paint: the production process of waterborne paint is to put all kinds of raw materials in a certain order and disperse evenly. The production process of general latex paint includes 3 parts: (1) slurry: first of all, water, dispersant, defoaming agent, preservatives and other liquid materials into the dispersion tank, mixing evenly, in the state of mixing will be colored pigments and physical pigments in turn into, and accelerate the dispersion of 20~40; (2) water-based paint: put emulsion in the paint mixing tank, and then add thickener, PH regulator, antifreeze, film forming agent, antifoaming agent and other additives, stirring about 15, to completely uniform, detect the material; 3. Coating filtering and product packing: in the production process of emulsioni paint, due to the small yan (filling) material has not yet been dispersed, or because of break emulsion particle, or the presence of impurities in the paint, so the coating should be filtered to remove coarse particle and impurity to obtain good quality products, can according to the requirement of the product is different, choose different specifications of the mesh screen and container packing, and make the measurement , so as to get the final product. (2) the main points in waterborne coating: (1) the material should be as dispersed as possible.

Zinc oxide, sodium pyrophosphate, β -naphthalene sulfonaldehyde condensation, part of the water → grinding → mixing (other materials) → filtration → finished waterborne coating production process: Zinc oxide, sodium pyrophosphate, β -naphthalene sulfonaldehyde condensation and 1.88 parts of water were mixed and ground in a ball mill for 20h. The resulting stable anticorrosive pigment was then mixed with the rest of the components and filtered to obtain a water-based paint. Waterborne coatings have become the trend of coatings development, the research and production of waterborne coatings will also be the top priority of coatings research.
