Abstract

The invention discloses a waterborne alkyd resin coating for a wooden product surface, which is prepared from, by weight, 80-90 parts of film forming substance, 1-2 parts of tetraethylenepentamine, 0.2-0.6 part of phenylenediamine, 1-5 parts of microcrystalline cellulose composite, 2-8 parts of calcined kaolin, 1-5 parts of vermiculite powder, 1-5 parts of glass fiber, 4-10 parts of pigment, 1-2 parts of magnesium oxide, 1-2 parts of antibacterial agent, 1-2 parts of mildew preventive, 1-2 parts of antifoaming agent, 1-2 parts of wetting agent, 15-22 parts of oxidized polyethlene wax, and 80-160 parts of water. The waterborne alkyd resin coating for the wooden product surface has good coating fullness, high hardness, good flexibility, and good waterproof and anti-scratching performance; moreover, the coating is featured by low VOC value and sticky resistance; meanwhile, the cost is low.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based alkyd resin coating used on the surface of wood products. Background technique [0002] In the product composition of wood coatings in my country, solvent-based products still occupy an important position. However, there are many harmful substances in the construction process of the product, which will cause certain harm to people's health. With the in-depth reform of environmental protection regulations, the requirements for surface coatings of wood products are becoming more and more stringent. Water-based wood coatings do not contain solvent-based organic volatiles. Advantages, the share in the coatings industry is gradually increasing. At present, the biggest problem of waterborne alkyd resin coatings is the shortcomings of water resistance and poor toughness, which need to be improved urgently. Contents of the invention [0003] Based on the technical prob...
