Preparation process of texture coating suitable for external wall insulation matching

Abstract

The invention discloses a preparation process of a texture coating suitable for external wall insulation matching, and relates to the technical field of coating processing, and the preparation processcomprises the following steps: 1) preparing titanium dioxide fibers by adopting a titanium chloride solution, absolute ethyl alcohol and distilled water; 2) preparing nano-scale carboxyl zinc stannate by taking zinc acetate dihydrate sodium stannate trihydrate as a raw material; 3) dispersing nanoscale zinc carboxystannate in the chitosan solution, and adding titanium dioxide fibers to prepare titanium dioxide composite fibers; 4) pretreating the titanium dioxide composite fiber; and 5) uniformly mixing the raw materials under a stirring condition to obtain the required texture coating. The pretreated titanium dioxide composite fibers are added into a conventional texture coating matrix, an intermolecular photoaddition reaction occurs under illumination, a cross-linked network is formed,the intermolecular interaction force in the coating matrix can be increased, the coating is not prone to cracking, the problem of tiny cracks caused by wall cracking can be solved, the service life ofthe coating is prolonged, and the appearance decoration effect is improved.

Description

technical field [0001] The invention belongs to the technical field of paint processing, and in particular relates to a preparation process of texture paint suitable for external wall heat preservation. Background technique [0002] With its infinitely varied three-dimensional textures and multiple choices of individual collocations, textured paints show a unique spatial perspective, rich and vivid, refreshing, and satisfy the overall decoration style with individual creations, making textured paints show themselves in the decoration unique style. This new type of art paint brings the smooth era of wall paint into a new era of natural environmentally friendly concave-convex paint, which can replace wallpaper, and is more environmentally friendly, economical and personalized. Texture paint has no radiation, light weight, and realistic effects. Through different construction techniques, techniques and techniques, it can create endless special decorative effects. This is a ne...

Problems solved by technology

For example, Chinese patent CN2006100447294 discloses an inorganic anti-cracking floor coating, which provides that adding anti-cracking chemical fibers in the coating can effectively prevent the cracking of the surface mortar, but in the coating matrix, the added anti-cracking chemical fibers are easily separated. Cross-linking and agglomeration occur, forming sedimentation, which makes the storage stability of the paint poor; another example is Chinese patent CN2011104257800 which discloses an elastic texture paint, which uses a special pure acrylic emulsion as the base material to prepare an elastic emulsion, which can effectively bridge the gap by improving the flexibility of the paint. Even the cracks of the wall, so as to achieve the technical effect of anti-cracking, but the improvement of the flexibility of the paint makes the surface hardness of the paint lower, and scratches are prone to appear under the action of external wind and sand, which destroys the aesthetics of the finish
