Exterior wall paint

Abstract

The invention discloses exterior wall paint. The exterior wall paint is prepared from the following raw materials in parts by weight: 20 to 30 parts of white latex, 12 to 18 parts of titanium dioxide, 2.3 to 4.5 parts of oxalic acid, 5 to 10 parts of kaolin, 3.5 to 7.6 parts of tetramethylhexaldehyde, 3.4 to 7.6 parts of 1,4-dithioerythritol, 1.2 to 3.5 parts of 4-nitroso-N,N-dimethylaniline and 2.2 to 4.6 parts of ethylene, chloroethylene and vinyl laurate ternary polymerized rubber powder. Compared with existing latex paint, by using control rheology performances of the kaolin and the titanium dioxide, medium and high shear viscosities of the paint are effectively improved and the water diversion tendency of the paint is improved; by using an efficient sterilization performance of the tetramethylhexaldehyde, the corrosion and demulsification of the paint are effectively prevented and the storage period of the paint is prolonged; by reasonably matching the 4-nitroso-N,N-dimethylaniline, the ethylene, chloroethylene and vinyl laurate ternary polymerized rubber powder and other auxiliary agents, the comprehensive performance of the paint is improved and commercial latex paint with low cost and high performances is prepared.

Description

technical field [0001] The invention relates to an exterior wall paint, which belongs to the field of architectural paints. 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 while ...

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
