Air purification material and preparation method thereof as well as produced art ware or material for decoration

Abstract

The invention discloses a material for purifying the air and a preparation method thereof. The material is prepared by taking activated carbon, a curing agent, an adhesive and a catalyst as raw materials, wherein the adhesive is a water-soluble adhesive, the catalyst is titanium dioxide, and the curing agent is gypsum powder or cement. The material is used for purifying the indoor air, has the advantages of strong adsorption capacity, quick molding, high strength and low cost, and can also produce activated carbon handicrafts and materials for interior decoration.

Description

technical field [0001] The invention relates to a material for purifying air and a preparation method thereof, as well as activated carbon handicrafts and interior decoration materials made of the material. Background technique [0002] With the improvement of living standards, people pay more and more attention to indoor air pollution. Relevant data show that the number of deaths due to indoor environmental pollution is as high as 2.8 million in the world every year. There are more than 300 pollutants in indoor air, accounting for about 68% of the human body. Diseases are related to indoor pollution. Therefore, effective purification of indoor air and elimination of air pollutants such as indoor toxic substances, smoke and peculiar smell are of great significance for maintaining human health. [0003] Activated carbon has a large surface area and can easily absorb toxic and harmful gases in the air, so it is widely used in indoor air purification in daily life. However, th...

Problems solved by technology

The material and its preparation method have the following disadvantages: first, the process is complicated and the equipment investment is large; second, it needs to be molded under high temperature and pressure, which consumes a lot of energy, has a long production cycle, and high production cost; third, the high temperature molding changes the The pore structure of activated carbon reduces the adsorption capacity; the fourth, the binder used in the molding is mesophase pitch (ie tar), and the mesophase pitch will produce toxic and harmful gases at high temperatures, which will affect the health of workers; fifth, the The molding speed of the material is slow during the preparation process; sixth, the prepared activated carbon material has poor mechanical properties, so it cannot be used in the field of high mechanical performance requirements, and is only suitable for the production of handicrafts that do not require high mechanical properties.
