Abstract

The invention belongs to a brushed latex paint applied to building exterior wall decoration. The latex paint is made of elastic polymer emulsion and silica sol as main raw materials. In order to improve the heat resistance, stain resistance and aging resistance of the synthetic resin emulsion type exterior wall brushed latex paint, the present invention adds silica sol in the formula, so that the organic exterior wall brushed latex paint becomes an organic-inorganic composite latex paint. This composite brushed latex paint for exterior walls has the comprehensive performance advantages of heat resistance, stain resistance, aging resistance of inorganic coatings and high bonding strength of organic coatings, stable storage and good paintability. In order to solve the storage of the exterior wall brushed latex paint after adding silica sol, add ammonia (or AMP-95 multifunctional additive) and OP-10 emulsifier or commodity wetting agent in the formula; Construction performance, adding high-viscosity cellulose ether to the formula to replace the ordinary viscosity cellulose ether currently used in exterior wall brushed latex paint.

Description

Technical field: [0001] The invention belongs to a kind of architectural paint, in particular to a latex paint used for roughening construction of building exterior walls. The latex paint has a better decorative effect than general roughening exterior wall latex paints. The original synthetic resin emulsion type paint is transformed into an organic-inorganic composite type paint, which can significantly improve the heat resistance, stain resistance and aging resistance of the synthetic resin emulsion type exterior wall brushed latex paint. Background technique: [0002] Present exterior wall brushed latex paint is prepared with synthetic resin emulsion (polymer emulsion) as film-forming substance. Although this type of brushed latex paint has many performance characteristics, it has problems such as poor pollution resistance, poor weather resistance and poor heat resistance. Especially when the temperature is high, the synthetic resin emulsion type brushed latex paint has a...
