Antibacterial, soundproof and environment-friendly diatomite wallpaper

Abstract

The invention discloses antibacterial, soundproof and environment-friendly diatomite wallpaper which comprises a bottom layer (1), a diatomite layer (2), a pattern color layer (3) and a wear-resistant layer (4) sequentially arranged from top to bottom, wherein the wear-resistant layer (4) is made of a polytetrafluoroethylene material. The thickness of the diatomite layer (2) is 0.1-0.3 mm. The bottom layer (1) is a glass fiber fabric, a nonwoven fabric or chemical fiber cloth. Bamboo carbon black is arranged on the wear-resistant layer (4). Diatomite in the diatomite layer (2) is obtained by adding raw diatomaceous earth with a grain size of 800-3000 meshes and a surface treating agent occupying 0.5-1 percent of the weight of the raw diatomaceous earth into a high-speed stirring machine capable of temperature rise, stirring at a high speed under the condition of 80-120 DEG C and treating for 90 minutes. The diatomite wallpaper disclosed by the invention is good in antibacterial, sound insulation, humidity control and absorption capacities and has good environment-friendly performance compared with a similar product.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to an antibacterial, sound-insulating and environment-friendly diatomite wallpaper. Background technique [0002] Diatomite is a kind of porous biological sedimentary rock formed by diagenesis under certain geological conditions after the accumulation of diatom remains of ancient single-celled lower plants. It is formed by the deposition of the remains of diatoms after they died. The diatom shell has a multi-level, large number and orderly arranged microporous structure, which makes diatomite have many excellent special properties: light weight, large surface area, high porosity, strong liquid adsorption capacity, high melting point; chemical stability High resistance, insoluble in hydrochloric acid, soluble in alkali; relatively incompressible, soft, sound insulation, wear-resistant, heat-resistant and many other excellent properties, so diatomite has been widely deve...
