Efficient air purifying material and preparation method thereof

Abstract

The invention discloses an efficient air purifying material and a preparation method thereof. The efficient air purifying material is prepared from the following raw materials in parts by weight: 80-250 parts of activated carbon, 10-50 parts of chitin nano-fiber, 5-35 parts of titanium dioxide, 10-60 parts of nano-zirconia, 0.5-4 parts of nano-lithospermum, 1-15 parts of nano-zinc oxide, 0.5-15 parts of nano-mint, 5-25 parts of epoxy resin, 40-100 parts of titanium ethoxide, 5-30 parts of citric acid, 1-15 parts of polyethylene glycol, 5-30 parts of sodium tripolyphosphate and 150-600 parts of absolute ethyl alcohol. The preparation method comprises the steps of uniformly stirring and mixing the raw materials, and carrying out evaporation drying, heating and compression molding, so as to obtain the efficient air purifying material. The efficient air purifying material prepared by virtue of the preparation method has the beneficial effects that the internal and external specific surface areas of activated carbon are increased, the adsorption capacity of the material to molecules of formaldehyde, ammonia gas and other volatile organic pollutants is improved, and the goals of purifying indoor air, preventing decoration defects and increasing the health level of residents are achieved; and the raw materials are easily available, a preparation process is simple, easy in operation and low in cost, and the efficient air purifying material is convenient to replace and applicable to industrial production and large-scale use.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to an efficient air purification material and a preparation method thereof. Background technique [0002] With the rapid improvement of people's living standards in our country, modern people's pursuit of quality of life and health is getting higher and higher. As a result, the housing area increases and the decoration becomes more and more luxurious and tight. However, due to our country's sanitary quality standards for building decoration materials, product quality supervision and management are not in place, resulting in a large number of inferior decoration materials flooding the building materials market. The survey shows that among the indoor environmental pollutants, four categories such as formaldehyde, ammonia, benzene (series) and radioactive substances are ubiquitous, the most harmful, and have become the greatest source of harm to the health of...

Problems solved by technology

However, there are only two types of activated carbon available in the market, powder and granular. The pore size of most activated carbons varies greatly, and the treatment effect on pollutant adsorption is not good, and the price is also high.
