Indoor decorative diatomite coating and preparation method thereof

Abstract

The invention discloses an indoor decorative diatomite coating and a preparation method thereof, wherein the indoor decorative diatomite coating comprises the following components in parts by weight:30-50 parts of diatomite, 3-5 parts of glass fibers, 4-6 parts of modified bentonite, 2.5-3.5 parts of magnesium sulfate, 1-3 parts of modified shell powder, 1.5-3.5 parts of water-soluble resin, 4-6parts of plant fibers, and 1-3 parts of an adhesive. The content of SiO2 contained in diatomite is more than or equal to 90% by weight, and the particle size of diatomite is 100-160 mesh. The diatomite material has large specific surface area and strong adsorption capacity, is combined with various mixed materials, light reflection is enhanced by the glass fibers, absorption of moisture and formaldehyde is enhanced by addition of the plant fibers, indoor air pollutants are greatly reduced, and the indoor environment is initiatively improved; diatomite has permeable pore diameter, the indoor decorative diatomite coating has extremely strong heat preservation property and sound absorption, and moreover, diatom mud can eliminate static electricity in indoor air, has a function of killing parasites and microorganisms, prevents a wall surface from getting mildew and changing color, and obviously reduces indoor peculiar smell.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to an interior decoration diatomite coating and a preparation method thereof. Background technique [0002] At present, in the research and development of anti-formaldehyde powder and coatings, most enterprises are committed to the research and development of environmentally friendly building materials, and new products are also launched in the interior wall market. Among them, the diatomite material is the biggest bright spot among these new products. Diatomaceous earth material is trusted and loved by designers and consumers for its many excellent properties (decomposition of free formaldehyde, respiratory humidity control, sterilization, etc.) and rich texture display ability. [0003] Diatom mud, diatom mud material, diatom earth material, and diatom mud coating all refer to the same thing, which is a new indoor health-care wall decoration material. According to the reasonab...

Problems solved by technology

[0005] The present invention proposes a diatomite coating for interior decoration and a preparation method thereof, aiming at the problem of low performance of the diatomite materials for internal walls in decomposing harmful substances such as formaldehyde, and develops a new type of environmentally friendly diatomite material, this new type of diatomite The soil material is composed of pure natural materials, without any harmful substances to the human body. It completely solves the harm of indoor environmental pollution to the occupants, and at the same time creates a primitive, simple and natural living environment for us; and in the adsorption , Decomposition and sterilization functions have a strong effect
