Powder decorative coating and its preparation and construction method

Abstract

The invention discloses a powder decoration coating and preparation and construction methods thereof, and belongs to the technical field of coatings. The powder decoration coating comprises raw materials in parts by weight as follows: 40-70 parts of shell powder of 1,000-2,000 meshes, 10-30 parts of a powder functional material, 2-10 parts of dispersible gelatin powder and / or a silicate cross-linked substance, 1-5 parts of sepiolite short-fibers and 5-30 parts of colorful composite rock slices. The powder decoration coating is prepared from the shell powder calcinated at the temperature of 300 DEG C, the powder functional filler, the colorful composite rock slices, the powder cross-linked substance and functional additives through blending, the shell powder calcinated at the temperature of 300 DEG C is taken as a main material, and the powder decoration coating is good in breathability, anti-condensation, scrubbing-resistant, pollution-resistant, anti-bacterial, mould-proof and non-inflammable and has a green and environment-friendly inorganic system and a colorful decoration effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a powder decorative coating and its preparation and construction methods. Background technique [0002] With the development of the country's economy and industry, the pollution of the human living environment by toxic and harmful substances in water, soil and the atmosphere has been highly valued by people and has become an urgent problem to be solved. As the most popular building decoration material used in the construction industry, paint is closely related to the pollution of indoor and outdoor environments. There are many kinds of coatings, and they are gradually developing in the direction of greening and multi-functionalization. Especially, interior decoration coatings are an important branch of functional coatings because they account for a large proportion of interior decoration. Due to its solvent-free and VOC-free properties, powder coatings have become the focus of ...

AI Technical Summary

Problems solved by technology

Although the product process is simple and low-pollution, but using a large amount of redispersible latex powder as a binder, the cost of adding nano-functional materials is relatively high, and the paint provides decoration by adding pigments, which may bring heavy metal pollution, and the decoration is relatively low. Poor; patent CN103011682B, this product uses inorganic nanomaterials and shell powder in-situ composite technology to process shell powder, which improves the antibacterial and anti-mildew properties of shell powder materials, but the preparation process is complicated, and the in-situ composite process calcines shell powder at high temperature 500℃, the microporous structure of the shell powder is destroyed, the function of humidity control and adsorption of harmful substances of the shell powder itself is attenuated, and the adhesive with polyvinyl alcohol as the main component is used as the film-forming material, and the poor water resistance is not suitable as a water-permeable product. Interior wall paint with steam function, and the decoration is not high, it is difficult to meet the requirements of designers
