Abstract

The invention discloses a durable emulsion paint. The durable emulsion paint is prepared from the following raw materials by weight: 2.5 to 3.9 parts of 1,3,3-trimethyl-bicyclo[2.2.1]heptan-2-oacetate, 2.7 to 4.4 parts of mica powder, 10 to 15 parts of titanium dioxide, 20 to 30 parts of latex, 3.7 to 6.8 parts of diethyl dithiophosphorate, 2.4 to 6.5 parts of alkylphenol polyoxyethylene and 2.1 to 6.5 parts of myristaldehyde. Compared with conventional emulsion paint, the emulsion paint provided by the invention has the following advantages: in virtue of the controllable rheological performance of the mica powder 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 diethyl dithiophosphorate, decay and demulsification of the paint are effectively prevented, and the storage period of the paint is prolonged; and through reasonable matching between alkylphenol polyoxyethylene 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 latex 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 harmful or...
