Improved paint for exterior walls

Abstract

The invention discloses an improved paint for exterior walls. The improved paint is prepared from the following raw materials (by weight): 20-30 parts of white emulsion, 12-18 parts of titanium dioxide, 2.3-4.5 parts of oxalic acid, 5-10 parts of kaolin, 3.5-7.6 parts of tetramethylhexanal, 3.4-7.6 parts of tribenzylphenol polyoxyethylene ether, 1.2-3.5 parts of a butadiene resin film-forming agent and 2.2-4.6 parts of a terpolymer rubber powder of ethene and vinyl chloride and vinyl laurate. In comparison with existing emulsion paints, the improved paint of the invention has advantages as follows: by controlled rheology of kaolin and titanium dioxide, intermediate and high shear viscosity of the paint is effectively raised, and water diversion tendency of the paint is improved; by efficient bactericidal performance of tetramethylhexanal, decomposition and demulsification of the paint are effectively prevented, and storage cycle of the paint is prolonged; and by rational combination of the butadiene resin film-forming agent, the terpolymer rubber powder of ethene and vinyl chloride and vinyl laurate and other auxiliary agents, comprehensive performance of the paint is raised, and an emulsion paint product with low cost and high performance is prepared.

Description

technical field [0001] The invention relates to an improved exterior wall paint and belongs to the field of architectural paint. Background technique [0002] Latex paint, also known as synthetic resin emulsion paint, is a kind of organic paint. It is a kind of water-based paint formulated with synthetic resin emulsion as the base material by adding pigments, fillers and various additives. According to different production materials, latex paint mainly includes polyvinyl acetate latex paint, ethylene-propylene latex paint, pure acrylic latex paint, styrene-acrylic latex paint and other varieties; according to different product application environments, it is divided into interior wall latex paint and exterior wall latex paint. There are two types of lacquer; according to the gloss effect of decoration, it can be divided into dull, matte, semi-gloss, mercerized and glossy. In the prior art, most latex paints use various formulas to eliminate harmful organic substances, but w...

Problems solved by technology

In the prior art, most latex paints use various formulas to eliminate harmful organic substances, but while the existing environmentally friendly latex paints improve environmental protection performance, they correspondingly reduce other performances of latex paints, such as wear resistance, anti-aging performance, etc. etc., while the production cost is higher
