Problems solved by technology

[0003] At present, the following types of exterior wall latex paints have been developed and put into use in my country: 1. Pure acrylic latex paint; 2. Silicone acrylic latex paint, whose weather resistance is better than pure acrylic latex paint; 3. Water-based fluorocarbon paint, It has good weather resistance, but the price is high; 4. Solvent-based exterior wall coatings have good weather resistance, but most of them are not environmentally friendly

Abstract

The present invention relates to outer wall paint, and is especially one kind of high performance nanometer outer wall paint and its preparation process. The nanometer outer wall paint has introduced organosilicon and fluoro resin to result in watertight coating with high permeation resistance and breathing function, water-thinned resin, nanometer titania particle, dispersing assistant and other assistants to make the paint possess well dispersed nanometer titania particle and excellent photocatalytic self-cleaning function.

Description

Technical field: [0001] The invention relates to the technical field of exterior wall paint, in particular to a high-performance exterior wall paint and a preparation method thereof. Background technique: [0002] High-performance exterior wall coatings mainly have the advantages of high weather resistance, stain resistance and high color retention. High weather resistance is the basic requirement for exterior wall decoration of high-rise buildings, and high stain resistance is a special requirement for the actual situation of environmental pollution in my country. At present, traditional building materials such as granite, mosaic, face brick, aluminum alloy glass are still used in most of the exterior wall decorations of buildings in our country. According to reports, the exterior walls of buildings in major cities in Western Europe are almost decorated with paint. Japan and other countries use coatings to decorate the building exterior walls as high as 70% to 90%. The bu...
