Sterilization and gas purification material for vehicle air conditioner filtration screens, and filtration screen preparation method

Abstract

The invention belongs to the technical field of fine chemicals, and particularly relates to a sterilization and gas purification material for vehicle air conditioner filtration screens, and a filtration screen preparation method, wherein the sterilization and gas purification material comprises the following raw materials, by weight, 30-50 parts of a negative ion releasing agent, 20-40 parts of anadsorption material, 20-40 parts of benzenediol, 10-30 parts of p-hydroxybenzenesulfonic acid, and 10-40 parts of polydimethylsiloxane. According to the present invention, after the filtration screenis sprayed with the sterilization and gas purification material, the filtration screen can release negative ions and inhibit bacterial proliferation so as to easily purify indoor air.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a sterilizing and air-purifying material used for automobile air-conditioning filter screens and a preparation method of the filter screen. Background technique [0002] The car air conditioner filter screen is the purification equipment on the car air conditioner. Commonly used filter materials include aluminum mesh, stainless steel mesh, non-woven fabric, fiber mesh, activated carbon filter, etc. The purification performance of these traditional materials is often not very ideal, and there are three disadvantages as follows: First, they can only block or simply filter Adsorbs some large particles, and has limited filtering effect on tiny particles. Second, the performance is single, and it can only play a filtering role. After a long time of use, the filter screen is prone to breed bacteria, which in turn produces peculiar smell, which brings harm to the hea...

Problems solved by technology

Commonly used filter materials include aluminum mesh, stainless steel mesh, non-woven fabric, fiber mesh, activated carbon filter, etc. The purification performance of these traditional materials is often not very ideal, and there are three disadvantages as follows: First, they can only block or simply filter Adsorbs some large particles, and has limited filtering effect on tiny particles

Second, the performance is single, and it can only play a filtering role. After a long time of use, the filter is easy to breed bacteria, which in turn produces peculiar smell, which brings harm to the health of the people in the car.

Third, the filter screen is easily contaminated with dust, and the dust clogs the mesh, which affects the efficiency of the air conditioner and increases energy consumption
