Abstract

The invention belongs to the field of filtration, and relates to the field of air purification, and in particular to a high-efficiency organic-inorganic composite filter material. According to the high-efficiency organic-inorganic composite filter material, aluminum oxide is taken as an inorganic material, polyvinyl alcohol as an organic material and tourmaline as negative ion powder, and a specific preparation method is provided. According to the invention, the problem of poor filtering effect in the prior art is solved, a non-absorbent negative oxygen ion system is formed by utilizing the insolubility of a biconjugated polymer formed by conversion of polyvinyl alcohol and the oxygen storage characteristics of negative ions of tourmaline powder and activated aluminum oxide, and the filtering and adsorbing effects are greatly improved.

Description

technical field [0001] The invention belongs to the field of filtration, relates to the field of air purification, in particular to a high-efficiency organic-inorganic composite filter material. Background technique [0002] At present, the ventilation filter is mainly made of PP, PET and other fiber textiles. It has good acid and alkali resistance, corrosion resistance, low resistance, and can be cleaned repeatedly. The economy is relatively high. In addition, The long and short fibers and dust particles captured by it are easy to clean, the filtration efficiency is not affected by cleaning, and the impact resistance is very good. It is the product of choice for customers. The air conditioning filter has a concave-convex honeycomb structure, which can be widely used in sewage filtration systems and air filtration. It is easy to clean and replace many times, and has a long-lasting effect. Moreover, the air conditioner filter is easy to clean, which is recognized by the majo...
