Corrosion-resistant and waterproof water-based paint

Abstract

The invention discloses corrosion-resistant and waterproof water-based paint which is prepared from the raw materials in parts by weight: 20 to 30 parts of epoxy resin, 60 to 80 parts of saturated linear polyester resin, 1 to 2 parts of pine tar, 15 to 25 parts of polyethylene wax, 1.2 to 2 parts of sodium dodecyl benzene sulfonate, 10 to 15 parts of glycol, 0.8 to 1.4 parts of calcium sorbate, 1 to 2 parts of rosin resin, 2 to 4 parts of thickener, 2 to 4 parts of cross-linking agent, 2 to 4 parts of pigment, 70 to 80 parts of filler and 40 to 60 parts of water. A wood fiber compound is prepared by the following technologies of adding water into soya flour; performing glue milling treatment; adding the polyethylene wax; warming and stirring; adding wood fiber, tung maleic anhydride methyl ester and dimethyl formamide and mixing; warming under a stirring state; continuing stirring; cooling to room temperature; filtering; washing solid by acetone; drying and smashing to obtain the wood fiber compound.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a corrosion-resistant and water-resistant water-based coating. Background technique [0002] With the improvement of human environmental awareness, architectural coatings are developing from the performance of protecting walls and decorations to multi-functional and green. The thermal insulation coating combines the dual characteristics of coatings and thermal insulation materials. After drying, it forms a thermal insulation layer with certain strength and elasticity, thus playing the role of thermal insulation. At present, although the thermal insulation coatings sold in the market have certain thermal insulation properties, their corrosion resistance, water resistance, and bonding strength are poor, which cannot meet the demand and need to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology...
