Problems solved by technology

[0003] With the rapid development of my country's economy, alkyd resin coatings have been more and more widely used in industry and agriculture, national defense, scientific research and people's lives. As a kind of liquid or fixed material that plays a protective, decorative and specific role, the current alkyd resin coatings have some shortcomings, such as the surface of the object after decoration is dull and unchanged, and the luminous effect cannot be displayed at night, which is harmful to production and construction personnel. Harmful, and there are a lot of microorganisms, bacteria, and germs in the environment, and most coatings have no antibacterial effect, so it is difficult for a single-performance alkyd resin coating to meet the diverse needs of the market

Abstract

The invention relates to truxenone derivative modified alkyd resin water-based paint which is composed of the following components: truxenone derivative modified water-based alkyd resin, acrylic acid modified water-based alkyd resin, water-based nano color paste, a wetting agent, a dispersing agent, an antifoaming agent, a leveling agent, a pH regulator, hydroxy cellulose, sepiolite fiber, a diatomite, an antifreezing agent and deionized water. The truxenone derivative modified water-based alkyd resin is prepared from vegetable oil acid, a truxenone derivative, cyclohexanediol monoacrylate, polybasic acid, polyhydric alcohol, xylene, tri(4-carboxylbiphenyl)amine, benzoic acid, dimethylolpropionic acid and a neutralizer through reaction. The truxenone derivative modified alkyd resin water-based paint prepared by the invention not only has the characteristics of truxenone, but also has the characteristics of Schiff base, has good antibacterial and bactericidal functions, and effectively solves the problems of unstable performance and the like caused by the addition of an antibacterial agent to the water-based paint.

Description

technical field [0001] The invention relates to a modified alkyd resin water-based coating, in particular to a terindone derivative modified alkyd resin water-based coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] Alkyd resin coatings occupy an important position in my country's coatings industry. According to incomplete statistics, the output of my country's alkyd resin paint and other alkyd resin-containing amino, nitro paint, perchlorethylene paint, and polyurethane paint occupies a major share of the paint market. The production of alkyd resin paint is large and there are many varieties. It is widely used and has a broad market prospect. It can be called a pillar product in the coatings industry. [0003] With the rapid development of my country's economy, alkyd resin coatings have been more and more widely used in industry and agriculture, national defense, scientific research and people's lives. As a kind o...
