Embodiment 1

[0022] Weigh zeolite 50 and chitosan 10, mix evenly, pulverize to below 200 mesh, add bamboo charcoal powder 80, mix, add pore former aqueous solution, pore former is 5 parts of sodium sulfate, granulate and pore, 80 degrees After drying, it is calcined at 200 degrees to obtain the finished product.

Embodiment 2

[0024] Weigh 80 parts of zeolite and 30 parts of chitosan, mix evenly, pulverize to below 200 mesh, add 100 parts of bamboo charcoal powder, mix, add the pore former aqueous solution, the pore former is 10 parts of sodium sulfate, 200 after drying at 80 degrees The finished product is obtained by roasting at a high temperature.

Embodiment 3

[0026] Weigh 70 parts of zeolite and 20 parts of chitosan, mix evenly, pulverize to below 200 mesh, add 90 parts of bamboo charcoal powder, mix, and 15 parts of sodium sulfate as the pore-forming agent, granulate and make pores at 100 degrees Celsius. The finished product is obtained by roasting at a high temperature.

Abstract

The invention discloses a method for preparing an air purification material. The method comprises the following steps of: weighing 50-80 weight parts of zeolite and 10-30 weight parts of chitosan, uniformly mixing, and crushing to the particle size of 200 meshes below; adding 80-100 weight parts of bamboo carbon powder, and uniformly mixing; adding 5-15 parts of pore-forming agent aqueous solution for pelletizing and forming pores, and performing drying treatment; and roasting the obtained products, thus obtaining the finished product. According to the technical scheme, the advantages of bamboo carbon and chitosan are combined, the manufactured product has a good air purification effect and a certain antibacterial dehumidification function, and the method is simple, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention specifically relates to a preparation method of an air purification material. Background technique [0002] In recent years, various health problems caused by decoration pollution have frequently appeared in the newspapers, and environmental protection in home decoration has become a topic of most concern to consumers. Indoor pollution is mainly four pollutants of formaldehyde, benzene, ammonia and radioactive substances, which are called "four pests". Formaldehyde is a recognized potential carcinogen in the world. It irritates the mucous membranes of the eyes and respiratory tract, etc., and eventually causes immune dysfunction, liver damage, lung damage and central nervous system to be affected. Now basically all families have used wood core boards, multi-layer plywood when decorating, or purchased furniture made of MDF. Adhesives are widely used in these boards, and the main pollutant in the adhesives is formaldehyde. The release per...
