Embodiment 1

[0044] The formula of multi-functional interior wall paint is: potassium silicate 9%, lithium silicate 3%, silica sol 13%, diatomaceous earth 9%, shell powder 7%, photosensitizing additive loaded tourmaline powder 11%, anti-radiation- Bactericidal additive loaded bentonite 11%, nano-SiO 2 Dispersion liquid 5%, calcined kaolin 4%, anatase titanium dioxide 6%, alumina powder 4%, water 18%.

[0045] The preparation method is as follows:

[0046] 1. Preparation of Photosensitizing Auxiliary Loaded Tourmaline Powder

[0047] (1) Add tourmaline powder into water according to the weight ratio of solid-liquid ratio of 1:5, stir and mix and carry out ultrasonic dispersion to form tourmaline powder suspension, and add 20% concentration of tourmaline powder to the suspension under stirring Glycine solution to a pH value of 6.0, then filtered, washed, and dried in a constant temperature oven at 60°C to obtain pretreated tourmaline powder;

[0048] (2) According to the volume ratio of e...

Embodiment 2

[0069] The formula of multi-functional interior wall paint is: 15% potassium silicate, 5% lithium silicate, 5% silica sol, 5% diatomaceous earth, 9% shell powder, 15% tourmaline powder loaded with photosensitizing additive, anti-radiation- Bactericidal additive loaded bentonite 5%, nano-SiO 2 Dispersion liquid 10%, calcined kaolin 2%, anatase titanium dioxide 3%, alumina powder 2%, water 24%.

[0070] The preparation method is the same as in Example 1.

Embodiment 3

[0072] The formula of multifunctional interior wall paint is: 5% potassium silicate, 2% lithium silicate, 10% silica sol, 15% diatomaceous earth, 5% shell powder, 5% tourmaline powder loaded with photosensitizing additive, anti-radiation- Bactericidal additive loaded bentonite 15%, nano-SiO 2 Dispersion liquid 2%, calcined kaolin 8%, anatase titanium dioxide 12%, alumina powder 8%, water 13%.

[0073] The preparation method is the same as in Example 1.

Abstract

The invention relates to a multifunctional inorganic interior wall coating and a preparation method thereof. The coating comprises the following components in percentage by weight: 5-15 percent of potassium silicate, 2-5 percent of lithium silicate, 5-20 percent of silica sol, 5-15 percent of diatomite, 5-10 percent of shell powder, 5-15 percent of photosensitive auxiliary-supported tourmaline, 5-15 percent of radiation-resistant-bactericidal auxiliary-supported bentonite, 1-10 percent of nano SiO2 dispersing liquid, 2-8 percent of calcined kaolin, 3-12 percent of anatase titanium dioxide, 2-8 percent of alumina powder and 10-25 percent of water; the total percentage by weight of all the components is 100 percent. The preparation method provided by the invention is simple; the obtained interior wall coating has the advantages of being non-toxic, odorless, green and environment-friendly, radiation-resistant, bactericidal and bacteriostatic, capable of eliminating formaldehyde and other organic pollutants, self-clean, capable of purifying air, releasing negative oxygen ions and regulating the humidity, fire-proof and flame-retardant, high temperature-resistant, water-resistant, scrubbing-resistant, aging-resistant, powdering-resistant and corrosion-resistant, thereby having wide market prospect.

Description

technical field [0001] The invention relates to a multifunctional inorganic interior wall paint and a preparation method thereof, belonging to the technical field of chemical paint preparation. Background technique [0002] my country's architectural coatings account for about 40% of the entire coatings industry, and architectural interior wall coatings account for 75% of architectural decorative coatings, which have attracted widespread attention. With the advancement of society and the continuous improvement of modern living standards, traditional interior wall coatings can no longer meet people's requirements for indoor living environments, especially volatile organic compounds (VOC), heavy metals, suspended particles, and disease germs brought about by environmental pollution. and other indoor pollution sources have seriously damaged human health and cannot provide a good living and working environment. In view of the problems existing in the durability, pollution, anti...
