Water-based epoxy anticorrosion coating for wooden buildings

Abstract

The invention discloses waterborne epoxy anticorrosive paint for a wooden building, and relates to the technical field of anticorrosive paint. The waterborne epoxy anticorrosive paint is prepared froman ingredient A and an ingredient B, wherein the ingredient A is prepared from the following raw materials in parts by weight: 70 to 80 parts of waterborne epoxy resin emulsion, 7 to 14 parts of methacrylic acid, 4 to 8 parts of N-(beta-aminoethyl)-gamma-aminopropyltrimethoxysilane (aminopropyltriethoxysilane), 0.2 to 0.6 part of ammonium persulfate, 7 to 15 parts of pigments, 4 to 8 parts of anti-corrosion pigments, 1 to 3 parts of talcum powder, 1 to 3 parts of mica powder, 5 to 10 parts of white carbon black, 2 to 6 parts of cosolvents, 1 to 3 parts of diacetone alcohol, 0.2 to 1 part of aerosil, 0.5 to 2 parts of anti-foaming agents, 0.2 to 1 part of wetting agent, 0.2 to 1 part of flattening agent and 7 to 14 parts of deionized water; the ingredient B is prepared from the following raw materials in parts by weight: 30 to 40 parts of waterborne polyamide epoxy hardeners, 10 to 17 parts of cosolvents and 7 to 14 parts of water. The waterborne epoxy anticorrosive paint provided by the invention has good water-resistant and anti-corrosion insect-proof performance; the inside decay and insect damage of the wooden building can be effectively prevented; the mechanical performance ofthe coating is excellent; the wear resistance and aging resistance are realized.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a water-based epoxy anti-corrosion coating for wooden buildings. Background technique [0002] With the improvement of people's living environment and the increasing awareness of environmental protection, more and more people begin to pursue more energy-saving and more comfortable green life. Wooden buildings are widely used in residential and other uses because of their inherent ecological characteristics It is favored by many advantages. However, as a natural organic material, wood has obvious biological characteristics and is easily attacked by organisms such as bacteria and insects. How to improve the antiseptic performance of wood is a technical problem that needs to be solved in the prior art. Coating protective coatings on the surface of wood can effectively improve the antiseptic performance of wood. [0003] Water-based epoxy coatings have many advantag...
