Dry powder type shell powder interior wall coating material and preparation method thereof

Abstract

The invention relates to a dry powder type shell powder interior wall coating material which has the functions of adsorbing and decomposing harmful gas and peculiar smell, restraining bacteria, sterilizing and resisting static electricity and using shell powder, nanometer inorganic filler and high molecular powder materials as main components. The invention solves the defects of high cost, high energy consumption, pollution and incapability of purifying indoor harmful gas in the existing interior wall coating materials. The coating material uses natural or manually cultivated shell powder as basic materials; meanwhile, a certain quantity of nanometer titanium dioxide and nanometer electric stone powder radiated by cobalt-60 gamma ray and the high molecular powder materials are added; the weight percentages of all components are as follows: 30-60% of shell powder, 10-20% of calcined kaolin, 10-20% of heavy calcium, 10-20% of talcum powder, 1-5% of nanometer titanium dioxide, 1-5% of nanometer electric stone powder, and 5-20% of high molecular powder materials; the particle size of the shell powder is 200-1250 meshes.

Description

technical field [0001] The invention relates to a new type of dry powder interior wall paint with the functions of absorbing and decomposing harmful gas and peculiar smell, antibacterial, sterilizing and antistatic, mainly composed of shell powder, nano inorganic filler and polymer powder. The invention solves the disadvantages of high cost, high energy consumption, pollution and inability to purify indoor harmful gases in the current interior wall paint. The coating has the functions of absorbing and decomposing harmful gas and peculiar smell, inhibiting bacteria and killing bacteria. 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 th...

Problems solved by technology

Latex paints generally have disadvantages such as soft paint film, long drying time, and poor storage stability. After being damp, latex paints are prone to breed bacteria, cause shedding, discoloration, etc., which seriously affect 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 our country, they need to be imported in large quantities, and the cost of raw materials is increasing year by year.
