Abstract

The invention discloses heat-resisting, damp-proof and environment-friendly paint suitable for furniture plates. The heat-resisting, damp-proof and environment-friendly paint is prepared from, by weight, 10-20 parts of modified phenolic resin, 10-15 parts of thermoplastic acrylic resin, 20-40 parts of alkyd resin, 20-30 parts of modified epoxide resin, 5-10 parts of nanometer calcium carbonate powder, 5-15 parts of nanometer titanium dioxide, 10-15 parts of nanometer zinc oxide, 5-10 parts of pentaerythritol, 30-40 parts of limonene, 1-2 parts of vermiculite powder, 20-40 parts of ethylene glycol and 0.5-2 parts of coupling agent. The heat-resisting, damp-proof and environment-friendly paint suitable for furniture plates is good in damp-proof and heat-resisting effect, safe, environmentally friendly, low in production cost and bright in paint color.

Description

technical field [0001] The invention relates to the field of home decoration, in particular to a heat-resistant, moisture-proof and environmentally friendly paint suitable for furniture boards. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for home decoration. Panels are frequently used materials in home decoration. Since panels are mostly made of wood materials, they are required to have better stability when exposed to the air for a long time. The paint with moisture-proof and heat-resistant functions has been developed rapidly. The shielding effect is the most basic protection mechanism of moisture-proof paint. It forms an inert isolation layer on the surface of the protected object to isolate the board from the environment and contain water and oxygen in the environment. , and other media are in contact with the plate, thereby retarding the occurrence of corrosion reactions. This effect of moisture-pro...
