Problems solved by technology

[0003] Water-based wood lacquers were studied earlier in our country, but until the 1980s, there were only a few varieties, including single-component and two-component ones. There are three major technical bottlenecks in water-based wood lacquers that affect water-based wood lacquers The promotion and use of: first, the hardness is low; second, the drying speed is slow; third, the fullness cannot meet people's requirements

Abstract

The invention relates to the technical field of wood paint and particularly relates to acrylic resin for water-borne wood paint primer, and aims to provide water-borne wood paint primer which has theadvantages of high solid content, low viscosity, high hardness, fast drying and high fullness. The acrylic resin is mainly prepared from the following raw materials in parts by weight: 5-15 parts of 2-hydroxypropyl acrylate, 10-20 parts of methacrylic acid, 20-30 parts of n-butyl methacrylate, 15-25 parts of isobornyl methacrylate, 25-35 parts of cycloaliphaticacrylate, 0.5-2 parts of initiator, 3.75-28 parts of silane coupling agent and 7.5-15 parts of prepolymer.

Description

technical field [0001] The invention relates to the technical field of wood lacquer, in particular to an acrylic resin for water-based wood lacquer primer. Background technique [0002] Wood paint refers to a type of resin paint used on wood products, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based. Formaldehyde, benzene, toluene, xylene and volatile organic compounds (VOC) contained in oily wood lacquer can damage human respiratory system, hematopoietic function, immune system and cause some genetic diseases. In recent years, there have been a lot of media reports on diseases such as leukemia, lung cancer, asthma, emphysema, and decreased immunity caused by these harmful substances after home decoration. The production process of water-based wood paint is a simple physical mixing process. Water-based wood paint uses water as a solvent without any harmful gas volatilization. It is currently the safest and most environmenta...
