Problems solved by technology

[0004] Acrylic resin coating is an important industrial decorative coating. Compared with other synthetic polymer resins, acrylic resin has many outstanding advantages, such as excellent light resistance, weather resistance, strong durability in outdoor exposure, and resistance to ultraviolet radiation. And turn yellow, good heat resistance, but acrylic paint has some defects in the use process, ordinary acrylic resin paint has no adsorption function, antibacterial, bactericidal function, so in order to get some special water-based acrylic paint, it is necessary to add some Some special functional additives or modify them

Abstract

The invention relates to a triptycene derivative modified acrylic resin water-based paint. The paint comprises the following components in parts by weight: 30.0-60.0 parts of triptycene derivative modified waterborne acrylic resin, 10.0-35.0 parts of fluorosilicone modified waterborne acrylic resin, 0.2-0.8 part of a wetting agent, 0.3-0.8 part of an antifoaming agent, 0.2-0.6 part of a leveling agent, 0.4-0.9 part of a pH regulator, 0.8-1.5 parts of hydroxy cellulose, 4.0-15.0 parts of nanoscale titanium dioxide powder, 0.0-25.0 parts of pigments and fillers and 10.0-40.0 parts of distilled water. The triptycene derivative modified acrylic resin water-based paint prepared by the preparation method disclosed by the invention does not need to be additionally added with a bactericide and has high bactericidal and antibacterial properties; the triptycene derivative is connected with the water-based acrylic resin through a chemical bond, is stable in performance and structure, and effectively overcomes the defects of uneven dispersion, easy sedimentation and the like of an additional adsorption auxiliary agent in the coating; and the triptycene derivative modified acrylic resin water-based paint prepared by the invention has the characteristics of high adhesive force, low surface tension, strong adsorption capacity, high antibacterial capacity and the like.

Description

technical field [0001] The invention relates to a modified acrylic resin water-based paint, in particular to a tripcene derivative modified acrylic resin water-based paint, which belongs to the technical field of water-based functional paints. Background technique [0002] At present, the coating building materials represented by latex paint are mainly composed of fillers and adhesives. The base materials are mainly chemical products. And during use, it will release toxic and harmful gases to the human body, such as formaldehyde, which will seriously endanger human health. [0003] People pay more and more attention to the environmental protection of decoration materials when decorating. In the process of interior decoration, wood boards, glue, wall paint, and furniture all contain more or less harmful substances such as formaldehyde and benzene series. It will be gradually emitted in years or even decades, thus affecting the health of the human body. [0004] Acrylic resi...
