Abstract

The invention relates to a PVDC copolymer emulsion for flame-retardant carpets and its preparation method and application. The invention uses a certain amount of vinylidene chloride, acrylonitrile, acrylate, silicone monomer and methacrylic acid as mixed monomers. The PVDC copolymer emulsion for flame-retardant carpets is prepared by emulsion polymerization. Due to the presence of organosilicon monomers and fluorine-containing surfactants, the flame-retardant carpets coated with the PVDC copolymer emulsion of the present invention not only have good environmental protection and flexibility. , high wear resistance, also has excellent flame retardancy, flame retardancy conforms to UL94 standard V-0 level, and burns and decomposes to emit white smoke; the carpet coated with PVDC copolymer emulsion of the present invention has better safety, Improve the quality of the product, welcomed by consumers.

Description

technical field [0001] The invention relates to a PVDC copolymer emulsion, in particular to a PVDC copolymer emulsion for flame-retardant carpets and a preparation method and application thereof. Background technique [0002] Carpets can be seen everywhere in life and are widely used in home users, hotels, hotels, and shopping malls. They are extremely flammable. Once a fire occurs, it will cause serious harm, especially in hotels, shopping malls and other places with a large flow of people. , more need flame retardant carpet. CN 201210571723.8 patent application discloses a PVDC copolymer emulsion for wear-resistant water-based floor paint, which has good environmental protection, wear resistance and flame retardancy, but when this emulsion encounters an open flame, it will emit thick black smoke after burning and decomposing , if a dangerous situation such as a fire occurs, it will hinder people's sight and prevent people from escaping. Contents of the invention [000...
