Abstract

The invention relates to a polyvinyl acetate emulsion paint and a preparation method thereof, and belongs to the technical field of emulsion paints. The polyvinyl acetate emulsion paint disclosed by the invention is prepared from the following raw materials in parts by weight: 40-50 parts of a polyvinyl acetate emulsion, 0.05-0.1 part of sodium polymethacrylate, 0.3-0.5 part of a dispersing agent, 0.2-0.4 part of sodium pentachlorophenate, 5-7 parts of carboxymethyl cellulose thickener, 1-2 parts of ethylene glycol, 2-3 parts of propylene glycol, 0.05-0.20 part of a defoaming agent, 15-20 parts of deionized water, 15-25 parts of titanium dioxide, 5-10 parts of charlton white, 10-15 parts of light calcium carbonate and 5-10 parts of talcum powder. Compared with an existing polyvinyl acetate emulsion paint, the polyvinyl acetate emulsion paint disclosed by the invention has the advantages that the production cost is low; the paint has good adhesive property with the coated surface; and a coating is durable in use.

Description

technical field [0001] The invention relates to a latex paint and a preparation method thereof, more specifically, the present invention relates to a vinyl acetate latex paint and a preparation method thereof, belonging to the technical field of latex paint.
