Abstract

The invention discloses an environment-friendly wood paint and a preparation method thereof. The environment-friendly wood paint is prepared from the following raw materials in parts by weight: 30-40parts of rosin-modified hydroxyl-terminated hyperbranched polyurethane, 10-20 parts of castor oil, 3-5 parts of chloroprene rubber emulsion, 4-6 parts of carboxyl-modified beta-cyclodextrin, 6-10 parts of sodium tetraborate, 10-15 parts of porous rare earth oxide, 5-10 parts of an alcohol solvent, 0.8-1.2 parts of an emulsifier, 1-2 parts of a leveling agent, 0.7-1 part of an antifoaming agent, 1-2 parts of a dispersant and 25-55 parts of water. The invention also provides a preparation method of the environment-friendly wood paint. The environment-friendly wood paint is better in waterproofness and wear resistance, faster in paint film drying, more excellent in dirt adhesion resistance, scratch resistance and weather resistance, and safer and more environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly wood paint and a preparation method thereof. Background technique [0002] Paint is a chemical mixture that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. Paint is widely used in our life, furniture, props, exterior walls, home decoration and handicrafts all need paint. Paint can make items bright in color, delicate in touch, fashionable and beautiful, and it also has special functions such as strong and durable, moisture-proof, high-temperature resistance, and corrosion resistance. Wood paint is one of the more common paints. It is a paint sprayed on the surface of wood to beautify the surface of wood and protect wood. It has the characteristics of moisture resistance, water resistance, oil resistance, and corrosion resistance. [0003] Most traditional wood paints are solvent-based paints, w...
