Material with air purification function and preparation method thereof

Abstract

The invention discloses a material with an air purification function and a preparation method thereof. The material comprises the following raw materials in parts by weight: 10-20 parts of modified attapulgite, 25-45 parts of a modified attapulgite formaldehyde adsorbent, 30-50 parts of a negative ion release agent, 15-25 parts of diatomaceous earth, 7-15 parts of powdered activated carbon, 6-14 parts of nano-TiO2, 4-10 parts of expanded perlite, 2-5 parts of redispersible rubber powder, 15-35 parts of polyethylene glycol and 3-7 parts of cellulose ether. The material with the air purificationfunction provided by the invention has advantages of high purification efficiency, long continuous purification time and large adsorption quantity, and can release negative ions, further improve airpurification effect and improve people's living environment at the same time.

Description

technical field [0001] The invention relates to the technical field of air purification materials, in particular to a material with air purification function and a preparation method thereof. Background technique [0002] At present, most of the materials with air purification function on the market use powdered activated carbon as the main adsorption and purification material, supplemented by composite indoor air purification particles made of various chemical purification materials. Although they have a certain air purification effect, there are still The purification efficiency is low, the continuous purification time is short, the adsorption capacity of the material is easily saturated, and it cannot be reused many times. [0003] In view of the above problems, the prior art was searched, and a preparation method of a diatomite composite air purification material was disclosed in the Chinese invention patent application 201210358131.8 (public date: January 9, 2013).

Problems solved by technology

[0002] At present, most of the materials with air purification function on the market use powdered activated carbon as the main adsorption and purification material, supplemented by composite indoor air purification particles made of various chemical purification materials. Although they have a certain air purification effect, there are still Defects of low purification efficiency, short continuous purification time, easy saturation of material adsorption, and inability to be reused many times

[0003] In view of the above problems, the prior art was searched, and a preparation method of a diatomite composite air purification material was disclosed in the Chinese invention patent application 201210358131.8 (public date: January 9, 2013). The purification material uses diatomite , tourmaline, flux, pore-forming agent and other materials are mixed and calcined, and the diatomite used in it has not been modified, so the purification material also has insufficient purification efficiency and cannot last for a long time. Defects in purifying the air

[0004] In China's invention patent application 201110031086.0 (public date: June 22, 2011), an oxidative air purification material and its preparation method, the method uses an inorganic oxidant to soak diatomite and then dry it, wherein Not only the diatomite used has not been modified, which has the disadvantages of low adsorption and purification efficiency and easy saturation of adsorption, but also the method of using inorganic oxidants to oxidize harmful substances may cause secondary pollution, low oxidation efficiency, and short purification time , can not be reused and many other defects
