Durable exterior-wall paint

Abstract

The invention discloses a durable exterior-wall paint. The durable exterior-wall paint is prepared from the following raw materials by weight: 20 to 30 parts of white emulsion, 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 tetramethylcaproic aldehyde, 3.4 to 7.6 parts of (tri(hydroxymethyl)methyl)glycine, 1.2 to 3.5 parts of 1-amino-2,3-propylene glycol and 2.2 to 4.6 parts of ethylene-vinyl chloride-vinyl laurate three-component copolymerization rubber powder. Compared with conventional emulsion paints, the durable exterior-wall paint provided by the invention has the following advantages: in virtue of the controllable rheological performance of the kaolin and titanium dioxide, high and medium shear viscosity of the paint is effectively improved and water diversion tendency of the paint is enhanced; through the high-efficiency sterilization performance of tetramethylcaproic aldehyde, decay and demulsification of the paint are effectively prevented, and the storage period of the paint is prolonged; and through reasonable cooperation among 1-amino-2,3-propylene glycol, ethylene-vinyl chloride-vinyl laurate three-component copolymerization rubber powder and other auxiliary agents, the comprehensive performance of the paint is improved, and the commercial emulsion paint with low cost and high performance is prepared.

Description

technical field

[0001] The invention relates to a durable exterior wall paint, which belongs to the field of architectural coatings. 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, b...
