Problems solved by technology

[0003] However, there are some defects in the use of acrylic resin coatings, such as the dull and unchanged surface after decoration, and the luminous effect cannot be displayed at night. At the same time, there are a large number of microorganisms, bacteria, and germs in the environment. Most acrylic resin coatings have no antibacterial effect. As a result, it affects the appearance and damages the surface of the coating, making the coating lose its protective effect. Therefore, it is difficult for a single-performance acrylic resin coating to meet the diverse needs of the market.

Abstract

The invention relates to a tripolyindanone derivative modified acrylic resin water-based paint which is composed of the following components in parts by weight: 100.0-150.0 parts of tripolyindanone derivative modified water-based acrylic resin, 20.0-40.0 parts of fluorine modified water-based acrylic resin, 0.6-2.4 parts of assistant, 3.0-6.0 parts of diatomite, 3.0-10.0 parts of nano silicon dioxide, 2.0-35.0 parts of pigment filler and 15.0-50.0 parts of deionized water. According to the tripolyindanone derivative modified acrylic resin water-based paint prepared by the preparation method disclosed by the invention, a coalescing agent does not need to be added, and a good film-forming property is realized; an antibacterial agent does not need to be added, and a good antibacterial function is achieved; light-emitting filler does not need to be additionally added, and good light-emitting performance is achieved; and due to the surface tension of the paint, the surface of the paint is difficultly covered by pollutants, and the performance is durable and stable.

Description

technical field [0001] The invention relates to a modified acrylic resin water-based paint, in particular to a terindanone derivative modified acrylic resin water-based paint, which belongs to the technical field of water-based functional paints. Background technique [0002] Acrylic resin paint is an important industrial decorative paint. Compared with other synthetic polymer resins, acrylic resins have many outstanding advantages, such as excellent light resistance, weather resistance, strong outdoor exposure durability, resistance to ultraviolet radiation, not easy to decompose and turn yellow, and good heat resistance. [0003] However, there are some defects in the use of acrylic resin coatings, such as the dull and unchanged surface after decoration, and the luminous effect cannot be displayed at night. At the same time, there are a large number of microorganisms, bacteria, and germs in the environment. Most acrylic resin coatings have no antibacterial effect. As a re...
