Abstract

The invention discloses a method for preparing a non-woven material, the non-woven material prepared by the method and application of the non-woven material to a filter. The method for preparing the non-woven material comprises the steps that (1) a pyridinium salt monomer is added in deionized water and stirred evenly, so that the molar concentration of the pyridinium salt monomer is 0.5 mol / L to1.0 mol / L to obtain a solution A; (2) a photoinitiator is added into the solution A to obtain a solution B; (3) a non-woven fabric is added into the solution B and stirred evenly to obtained a mixtureC; (4) the mixture C is filled with nitrogen for bubbling for 10 min and then sealed, and an ultraviolet lamp is turned on in the constant temperature water bath for irradiation grafting reaction; and (5) a product after the irradiation grafting reaction is washed with acetone, then extracting is conducted for 24 hours, drying is conducted below 60 DEG C, so as to obtain the non-woven material. The non-woven material prepared by the method maintains the original filtration performance of the non-woven fabric, and meanwhile also has good antibacterial and anti-corrosion properties.

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 brings great harm to the health of car owners. How to improve the air quality in the car has become a topic of close concern to the majority of car owners. [0003] With its excellent filtration performance, low cost, high output, easy compounding, wrinkle resistance, short web forming process, and ...
