Composite material with anti-bacterial and purifying functions and preparation method of composite material

Abstract

The invention relates to a composite material with anti-bacterial and purifying functions and a preparation method of the composite material, and belongs to the technical field of environmental-friendly materials. The composite material with the anti-bacterial and purifying functions comprises raw materials in parts by weight as follows: 70-95 parts of a mineral composite adsorption material, 3-25 parts of a photocatalytic degradation material, 2-15 parts of a rare earth inorganic anti-bacterial material and 1-10 parts of an additive, wherein the mineral composite adsorption material is prepared from sepiolite, diatomite, medical stone and attapulgite; the photocatalytic degradation material is prepared from titanium oxide, tourmaline and far infrared ceramic powder; the rare earth inorganic anti-bacterial material is prepared from zinc oxide, cerium oxide and silver oxide; the additive is a mixture of activated carbon, carboxymethylcellulose and pumice powder. The composite material with anti-bacterial and purifying functions has high adsorption and decomposition rate, can be resistant to water and damp and has excellent anti-bacterial effect. Meanwhile, the invention provides the preparation method. According to the preparation method, the cost is low, the amount of produced wastewater is low, and powder is simple and convenient to apply.

Description

technical field [0001] The invention relates to an antibacterial and purifying functional composite material and a preparation method thereof, belonging to the technical field of environmental protection materials. Background technique [0002] Indoor pollution has become an important threat to people's healthy life at home. Statistics from the China Environmental Protection Association show that: 90% of children with leukemia have had luxury decoration in their homes, and 2.1 million children die of luxury decoration every year; 80% of home decoration has excessive formaldehyde; 70% of pregnant women's miscarriage is related to environmental pollution; every year in China, the number of deaths caused by indoor environmental pollution is as high as 111,000, with an average of 304 deaths per day. Indoor environmental pollution has become one of the killers that seriously affect the health of modern humans. [0003] The use of adsorbent materials to purify indoor polluted air...

Problems solved by technology

However, there are also a small number of companies that take the route of low-price dumping, and some companies even use cement balls as tourmaline balls and clay balls as far-infrared balls and other products. This is not only not conducive to the development of the industry, but also leads to disorderly development of the industry.

[0012] To sum up, mineral products used for air purification and water purification have high adsorption decomposition and high-efficiency antibacterial functions, and products and technologies that can be used for water purification and air purification have not yet been developed.
