Abstract

The invention discloses a preparation method of an anti-yellowing carpentry paint. The preparation method is as follows: (1) adding 15 to 18 parts of polyethylene in a reaction kettle, heating up to 50-80 DEG C, adding 100 parts of alcohol-resistant hydroxyl acrylic resin, 30-35 parts of titanium white and 1-3 parts of an activator, continuing to heat up; (2) when the temperature is risen to 90-100 DEG C, adding 0.8 part of activated carbon and 0-0.5 part of a levelling agent, keeping the temperature for 1 hour, adding 1-3.5 parts of a film-forming agent, keeping the temperature for 1-1.5 hours; and (3) cooling to 50 DEG C, adjusting the PH value to 6-7, and then discharging. 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 preparation method of wood lacquer, in particular to a preparation method of anti-yellowing wood lacquer prepared by using 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] Goal of the invention: in order to overcome the deficiencies in the prior art, the object of the inventio...
