Problems solved by technology

[0002] At present, the floor paints used in the market are mainly solvent-based. Solvent-based floor paints have the advantages of low film-forming temperature, strong adhesion, high wear resistance, and good water resistance. However, they will release a large amount during production and use. Volatile organic compounds, which bring certain harm to the environment and human health; with the enhancement of people's awareness of environmental protection and safety, the use of water-based floor paint instead of solvent-based floor paint has become a future development trend
At present, relevant research has also made some progress, such as the patent application of CN200810030503, which discloses a water-based paint that can be used for floors. Its components include acrylic acid emulsion, glycerin, xylitol, sodium pyrophosphate, water, and have good environmental protection. property, but this water-based paint has insufficient abrasion resistance when it is used for flooring; the patent application of CN201010163994 discloses a kind of water-based acrylic polyurethane topcoat, which is prepared by adding auxiliary agents such as titanium dioxide and talcum powder with water-based acrylic resin as base material, Good water resistance, weather resistance, chemical resistance and high abrasion resistance, but not flame retardant

Abstract

The invention discloses a PVDC (polyvinyl dichloride) copolymer emulsion for a wear-resistant water-based floor paint, as well as a preparation method and an application thereof, and solves the problems of poor wear resistance, no flame resistance and the like. The wear-resistant water-based floor paint is prepared by taking a certain amount of vinylidene chloride, vinyl chloride, vinyl cyanide and acrylic ester as mixed monomers and carrying out emulsion polymerization. Due to the existence of chloride atoms, the water-based floor paint prepared with the PVDC copolymer emulsion is good in environmental friendliness, high in wear resistance and excellent in flame resistance; and a floor coated with the floor paint is better in safety, the product quality is improved and the product is popular with consumers.

Description

technical field [0001] The invention relates to a PVDC copolymer emulsion, in particular to a PVDC copolymer emulsion for wear-resistant water-based floor paint and its preparation method and application. Background technique [0002] At present, the floor paints used in the market are mainly solvent-based. Solvent-based floor paints have the advantages of low film-forming temperature, strong adhesion, high wear resistance, and good water resistance. However, they will release a large amount during production and use. The volatile organic compounds in the floor will bring certain harm to the environment and human health; with the enhancement of people's awareness of environmental protection and safety, the use of water-based floor paint instead of solvent-based floor paint will become a future development trend. At present, relevant research has also made some progress, such as the patent application of CN200810030503, which discloses a water-based paint that can be used for...
