Nano hollow TiO2/shell powder interior wall coating material capable of decomposing harmful gases efficiently and preparation method therefor

Abstract

The invention discloses a nano hollow TiO2 / shell powder interior wall coating material with a high-efficiency harmful gas decomposition function and without bubbles in a spraying process. Mainly, shell powder and a nano hollow titanium dioxide material are subjected to combination treatment, and a surface-assembly-type nano-hollow TiO2 / shell powder complex interior wall coating material is prepared. The interior wall coating material is composed of, by weight, 40%-70% of nano hollow TiO2 / shell powder complex, 5-10% of calcium bentonite, 10%-30% of modified high-molecular film forming material, 5-10% of nano calcium carbonate and 10-20% of heavy calcium, wherein, the nano hollow TiO2 / shell powder complex is prepared from 30g of shell powder and 0.1 mol of nano hollow TiO2 through combination. The prepared interior wall coating material has good adsorption function, has a good function of decomposing indoor harmful gases, has good bacteriostasis, sterilization and antistatic functions, and is advantaged by rapid curing speed, hard paint surface, high covering performance, plump, smooth and bright paint film, high dirt resistance and low production cost.

Description

technical field [0001] The invention belongs to the technical field of polymer nano-composite materials, and in particular relates to a nano-hollow TiO that efficiently decomposes harmful gases 2 / Shell powder interior wall paint and preparation method thereof. Background technique [0002] Shell powder paint is a new type of ecological interior wall paint. It has the function of absorbing indoor harmful gases (formaldehyde, benzene, TVOC, ammonia) and regulating air humidity; Children, patients, pets, molds, and indoor miscellaneous odors are all effective in removing, especially for carbon monoxide and floating dust emitted by smoke in the room; the chitin film contained in shell powder is effective against E. It has a strong antibacterial and bactericidal effect, and it also has a significant effect on Salmonella and Glucobacterium flavum; antistatic performance: shell powder uses natural shells as raw materials, and its main component is calcium, so it has good antista...

AI Technical Summary

Problems solved by technology

However, the function of completely decomposing indoor harmful gases (formaldehyde, benzene, TVOC, ammonia) is very small. At the same time, due to the use of ordinary powdery polymer materials as film-forming materials, a large number of bubbles are generated during the spraying process, resulting in poor covering and paint. Surface is not smooth
