Problems solved by technology

As can be seen from its description, the invention mainly utilizes the concentrated medicinal liquid of Chinese herbal medicine, and first mixes it with sodium tripolyphosphate, hydroxymethyl cellulose, sodium alginate, polyvinyl alcohol, water glass, alkyd resin, epoxy Resin and polypropylene wax are mixed, and then mixed with talcum powder and montmorillonite powder. Since the active ingredients in the liquid medicine are alkaloids, volatile oils, etc., the volatile oils have a good bactericidal effect, but in practical applications, due to the external environment The effect of active ingredients is extremely volatile and thus loses the antibacterial effect
Therefore, the popularization and applicability of coating among the present invention is relatively poor

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of an antibacterial and anti-cracking water-based paint for wood products. Background technique [0002] Wood is a kind of porous fibrous tissue of polysaccharides. Due to different growth regions and climates, its internal structure varies greatly, and it has hydrophilic expansion and contraction properties. The standard moisture content of wood is generally set at 12-18% in China, and 15% in Japan. The standard moisture content in Europe and America is 12%. Wood is a porous hygroscopic material, too high or too low moisture content will directly cause problems such as cracking, peeling, whitening of the paint film and long-term non-drying. In addition, bacteria are easy to grow on the surface of wood products during use, which affects the service life of wood products. Water-based coatings, which are diluted with water, free of TDI,...
