Water-based paint based on nano shell powder and preparation method thereof

Abstract

The invention provides a water-based coating based on nano-shell powder and a preparation method thereof, which is composed of the following components and parts by weight: 30-60 parts of nano-shell powder, 10-20 parts of calcined kaolin, 10-20 parts of heavy calcium, styrene-acrylic acid 20~30 parts of emulsion, 9~10 parts of solid resin solution, 5~20 parts of wax emulsion, 5~30 parts of defoamer, 10~20 parts of styrene, 3~5 parts of protective glue, 2~3 parts of cellulose colloid , 5~6 parts of starch colloid, 1.2~1.5 parts of methacrylic acid, 0.1~1.5 parts of initiator, 0.2~0.8 parts of antifungal agent, 2~3 parts of deionized water. The invention adopts green raw materials, the paint is safe and environment-friendly, has excellent effects of purifying indoor air and regulating indoor humidity, has simple production process and low preparation cost.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, and in particular relates to a water-based paint based on nano shell powder and a preparation method thereof. Background technique [0002] The architectural interior wall coatings used in the market are mainly latex paints. Latex paints generally have disadvantages such as soft paint film, long drying time, and poor storage stability. After the latex paint is damp, it is easy to breed bacteria, cause peeling, discoloration, etc., which seriously affects the service life and indoor appearance. At the same time, latex paints consume a lot of oil. Due to the lack of oil resources in my country, a large amount of imports is required, and the cost of raw materials increases year by year. [0003] Shell powder is made by calcining and crushing artificially cultivated and natural shells at high temperature. Its components are calcium carbonate, calcium oxide, calcium hydroxide and other cal...

Problems solved by technology

This invention solves the shortcomings of current interior wall coatings, such as high cost, high energy consumption, pollution and inability to purify indoor harmful gases.

The coating uses natural or artificially cultivated shell powder as the basic material, and simultaneously adds a certain amount of nano-titanium dioxide and nano-tourmaline powder and polymer powder materials irradiated with cobalt-60 gamma rays. The weight of its various components is 100%. The distribution ratio is: 30%-60% shell powder, 10%-20% calcined kaolin, 10%-20% heavy calcium, 10%-20% talc, 1-5% nano titanium dioxide, 1-5 % nano tourmaline powder, 5%-20% polymer powder material; the particle size of the shell powder is 200 mesh-1250 mesh, but the coating may be degraded by microorganisms, the validity period is not ideal, and it is not effective in purifying indoor air. room for improvement
