Abstract

The invention discloses improved exterior wall paint. The improved exterior wall paint is prepared from the following raw materials in parts by weight: 20-30 parts of white latex, 12-18 parts of titanium powder, 2.3-4.5 parts of oxalic acid, 7.3-8.5 parts of deionized water, 5-10 parts of kaolin, 3.5-7.6 parts of tetramethyl caproaldehyole, 3.4-7.6 parts of tribenzyl phenol polyoxyethylene ether, 1.2-3.5 parts of butadiene resin binder and 2.2-4.6 parts of redispersible latex powder. Compared with the conventional latex coating, the improved exterior wall paint has the advantages that through the rheology behavior controlling performance of the kaolin and the titanium powder, the medium and high shearing strength of the coating is effectively enhanced, and the water diversion tendency of the coating is improved; through the efficient sterilizing performance of the tetramethyl hexaldehyde, the corrosion and demulsification of the coating are effectively prevented, and the storage period of the coating is prolonged; through reasonable matching of a butadiene resin binder, re-dispersible latex powder and other aids, the comprehensive performance of the coating is enhanced, low-cost and high-performance commercial latex paint is prepared.

Description

technical field [0001] The invention relates to an improved exterior wall paint and a preparation method thereof, belonging 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 ...
