Embodiment 1

[0026] A shell powder indoor air purification wall material, calculated by the mass sum of 100%, consists of 30% shell powder mixture (1250 mesh particle size), 5% chitosan, 25% ash calcium, 10% microporous partial Calcium silicate, 10% calcium ferrite, 10% washed kaolin and 10% polymer copolymer binder.

[0027] Wherein, the polymer copolymer binder acts as a film-forming and curing function, and it is composed of vinyl acetate-acrylate-vinyl tert-carbonate copolymer, ethylene-vinyl acetate copolymer and gypsum powder; The mass percentages of the components are: 20% of vinyl acetate-acrylate-vinyl tert-carbonate copolymer, 20% of ethylene-vinyl acetate copolymer, and 10% of gypsum powder.

[0028] The shell powder mixture is prepared by calcining and pulverizing at a high temperature of 460°C, the particle size of the shell powder mixture is 1250 mesh, and the shell powder mixture is a mixture of Hawaiian shell powder, pearl shell powder, oyster shell powder and crab shell po...

Embodiment 2

[0040] A shell powder indoor air purification wall material, calculated by mass sum as 100%, is composed of 35% shell powder mixture (800 mesh particle size), 10% chitosan, 15% ash calcium, 10% microporous partial Calcium silicate, 10% calcium ferrite, 10% washed kaolin and 10% polymer copolymer binder.

[0041] The preparation method is the same as in Example 1.

Embodiment 3

[0043] A shell powder indoor air purification wall material, calculated by the mass sum of 100%, consists of 40% shell powder mixture (particle size 1250 mesh), 10% chitosan, 10% ash calcium, 10% microporous partial Calcium silicate, 5% calcium ferrite, 10% washed kaolin and 15% polymer copolymer binder.

[0044] The preparation method is the same as in Example 1.

Abstract

The invention discloses a shell powder indoor air purification wall material and a preparation method thereof and belongs to the technical field of polymer composite materials. The shell powder indoor air purification wall material is composed of 30% to 60% by mass of a shell powder mixture, 5% to 20% by mass of chitosan, 10% to 40% by mass of ash-calcium, 5% to 20% by mass of microporous calcium metasilicate, 5% to 15% by mass of calcium ferrite, 5% to 20% by mass of washed kaolin and 10% to 25% by mass of a copolymer binder. The material can highly efficiently adsorb and decompose harmful substances and odor and has functions of bacteriostasis, sterilization and electric resistance. The used chitosan can be used for decomposing to remove harmful substances such as formaldehyde in air, has a removal rate of 99% and effectively reduces the formaldehyde content to 0.05%. The amine group (-NH2) having high reaction activity in the chitosan can react with many gaseous harmful substances to be decomposed into water and oxime.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, in particular to an indoor air purification wall material mainly composed of shell powder and chitosan and a preparation method thereof. Background technique [0002] Latex paint, paint, composite board, leather, foam filler and other materials widely used in interior decoration and furniture contain a large amount of volatile toxic compounds, especially benzene, xylene, and formaldehyde, which seriously pollute indoor air and endanger the health of people, especially children. healthy. The interior decoration wall materials currently on the market are mainly latex paint, diatom mud, and wallpaper. None of these materials can purify indoor air, and they themselves contain harmful substances. At home and abroad, more and more attention is paid to the research of green environmental protection decorative wall materials with the ability to purify the air, but so far there is no...
