Abstract

The present invention provides a preparation method for a non-woven fabric material, the non-woven fabric material prepared by the method, and the application of the non-woven fabric material in a filter. The preparation method for the non-woven fabric material comprises the steps that: (1) a quaternary ammonium salt monomer is added into deionized water and is stirred evenly, so that a molar concentration of the quaternary ammonium salt monomer is 0.6-1.4 mol / L, so as to obtain solution A; (2) an initiator is added into the solution A to obtain solution B; (3) a non-woven fabric is added intothe solution B and is stirred evenly to obtain mixture C; (4) the mixture C is filled with nitrogen, bubbled for 10 minutes, and then sealed, and a redox grafting reaction in a constant temperature water bath is carried out; and (5) a product after the redox grafting reaction is washed with acetone, extracted for 24 hours and dried, so as to obtain the non-woven fabric material. The non-woven fabric material prepared by the method has strong filtering performance and good antibacterial and anti-corrosion performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for preparing a non-woven material, a non-woven material prepared by the method and an application of the non-woven material in a filter. Background technique [0002] With the continuous development of my country's economy, automobiles have become an indispensable means of transportation for people's daily life. As the number of private cars in cities increases year by year, the air pollution on the road is becoming more and more serious. However, the space inside the car is small and the air circulation is poor, which is not conducive to the diffusion of pollutants, and is easy to breed bacteria, which has a great impact on the health of car owners. hazards. How to improve the air quality in the car has become a topic of close concern to the majority of car owners, and the air conditioner filter with antibacterial function will be an effective means to solve this ...
