Abstract

The invention provides a vinyl acetate-ethylene-vinyl versatate copolymer emulsion. The vinyl acetate-ethylene-vinyl versatate copolymer emulsion is prepared by an emulsion polymerizing method of copolymerizing with a vinyl acetate monomer, an ethylene monomer and a vinyl versatate modification monomer as basic raw materials and water as a dispersion medium in the presence of protective colloid and under the effects of an emulsifying agent, an initiating agent and a cross-linking agent. The vinyl acetate-ethylene-vinyl versatate copolymer emulsion comprises the following raw materials in parts by mass: 40 to 70 parts of vinyl acetate, 5 to 15 parts of ethylene, 10 to 30 parts of vinyl versatate, 0.4 to 2.5 parts of compound emulsifier, 0.5 to 2.5 parts of protective colloid, 0.1 to 0.3 parts of initiating agent, 0.5 to 2.5 parts of cross-linking agent, and 50 to 75 parts of water. The copolymer emulsion is small in grain size, high in paint filler bearing capacity, high in vitrification temperature, and low in the closest filming temperature; the prepared coating is relatively high in scrub resistance, low in residual monomer, environmentally-friendly, and pollution-free. The synthesis method of the copolymer emulsion is simple and easy in process and operation, convenient and fast, and convenient for industrial production.

Description

technical field [0001] The invention relates to a copolymer emulsion for architectural coatings, in particular to a vinyl acetate-ethylene-ethylene tertiary carbonate copolymer emulsion and a synthesis method. Background technique [0002] Interior wall latex paint is the most widely used variety of architectural coatings, and its main function is to decorate and protect interior walls. Compared with wallpaper, wall covering, ceramic tile, mosaic and other decorative materials, it has the advantages of bright colors, rich shapes, good decorative effect, excellent performance, good protection effect, convenient construction, easy maintenance, and various construction methods. [0003] The interior wall latex paint is mainly composed of binders, pigments and fillers, additives and water, of which the binder is the most important component and plays a decisive role in the performance of the latex paint. At present, the base materials of interior wall latex paint in my country ...
