Abstract

The invention provides an air filtering material as well as a preparation method and application thereof. The preparation method is implemented through the following steps of (1) alkalization: respectively performing alkalization action on coarse fiber raw materials and fine fiber raw materials to obtain coarse fiber prepared materials and fine fiber prepared materials; (2) distillation: performing distillation action on middle fiber raw materials to obtain middle fiber preparation materials; (3) cracking: putting the preparation materials into a plant fiber cracking treatment system for cracking; respectively obtaining coarse fiber, medium fiber and fine fiber; (4) mixing: proportionally putting the coarse fiber, the middle fiber and fine fiber into a cyclone sieve; performing stirring toobtain uniformly mixed finished product filtering materials. No any additives are used; no any side effect is caused on the human body; the filtering effect is good; the natural scent material also has the effects of health care and refreshing. In addition, the cost is low; the environment-friendly effect is high.

Description

technical field [0001] The invention relates to the technical field of air filter production, in particular to an air filter material and its preparation method and application. Background technique [0002] As the smog weather becomes more and more serious, the application of air purification devices has become more and more extensive. Among them, the air filter element is an essential part of the air purification device. [0003] At present, in the existing air purification devices, the air filter element is generally a paper filter element, that is, the air filter material is filter paper. In order to improve the strength of the filter paper, it is necessary to add phenolic resin or other additives to the filter paper. Since the phenolic resin or other additives have certain side effects on the human body, the paper filter element has certain side effects on the human body during use. Contents of the invention [0004] Based on this, the purpose of the embodiments of ...
