Abstract

The invention discloses an anti-yellowing carpentry paint which comprises the following raw materials by weight: 100 parts of alcohol resistant hydroxyl acrylic resin, 30-35 parts of titanium dioxide, 15-18 parts of polyethylene, 1-3 parts of an active agent, 0.8 part of activated carbon, 0-0.5 part of a leveling agent and 1-3.5 parts of a film-forming agent; wherein the alcohol resistant hydroxyl acrylic resin comprises the following components by weight: 100 parts of methyl methacrylate, 8-20 parts of perfluoroalkylethyl acrylate monomer, 15 parts of hydroxyethyl acrylate, 25-35 parts of butyl acrylate, 3-7 parts of iso butyl methacrylate, 1.5-5 parts of an initiator and 50-70 parts of a solvent 2. The alcohol resistant hydroxyl acrylic resin has a high alcohol resistant performance and high corrosion resistance, is low in solvent price and simple in preparation process, can be widely used in auto repair paints, and can improve the sunproof and anti-corrosion performance of the auto repair paints. The anti-yellowing carpentry paint is strong in corrosion resistance, is anti-yellowing, can keep carpentry beautiful for a long time, and is easy to use, simple in preparation and low in cost.

Description

technical field [0001] The invention relates to a wood lacquer, in particular to an anti-yellowing wood varnish prepared by using an alcohol-resistant hydroxy acrylic resin. Background technique [0002] Acrylic resin does not undergo further cross-linking during the film-forming process, so its relative molecular weight is relatively large, it has good gloss and color retention, water and chemical resistance, fast drying, convenient construction, easy construction, recoating and rework, and the preparation of aluminum The whiteness and positioning of aluminum powder are good in powder coating, so thermoplastic acrylic resin is widely used in wood lacquer. [0003] However, the wood paints currently on the market are prone to yellowing, making the wood easily aging and affecting the appearance. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of an...
