Manufacturing method of antibacterial electret for disassembly-free and washing-free filtering equipment

Abstract

The invention relates to a manufacturing method of an antibacterial electret for disassembly-free and washing-free filtering equipment, and belongs to the technical field of materials. The manufacturing method comprises the following steps of 1, sequentially weighing ETFE resin, energy storage powder, an antibacterial agent and a processing aid according to a certain mass ratio, and then putting into a mixer; 2, stirring at a low speed for a certain time, and extruding and granulating through parallel twin screws to obtain the electret with antibacterial and sterilizing functions; and 3, preparing various porous filtering devices according to product requirements, and carrying out electret work by using electret equipment so as to obtain the antibacterial electret with the low surface energy of a 3000v electrostatic field and a filtering function. According to the manufacturing method of the antibacterial electret for the disassembly-free and washing-free filtering equipment provided by the invention, the electret is made into a porous air channel, dust particles, viruses, bacterial particles and the like are adsorbed to the surface of the material while air passes through the electret, and the viruses and bacteria are killed by using an antibacterial agent exposed on the surface of the material.

Description

technical field [0001] The invention relates to a method for manufacturing an antibacterial electret, in particular to a method for manufacturing an antibacterial electret used in a non-dismantling and cleaning filter device, which belongs to the field of material technology. Background technique [0002] The air purifier uses a high-voltage electrostatic generator to generate a high-voltage electric field to remove dust, which consumes high energy, is unsafe, and is prone to ionization to generate ozone, causing secondary pollution; the filtering effect of activated carbon adsorption is affected by the use time and particle size, and after work As solid waste, activated carbon needs to be further treated, and there is also a hidden danger of secondary pollution.

[0002] The air purifier uses a high-voltage electrostatic generator to generate a high-voltage electric field to remove dust, which consumes high energy, is unsafe, and is prone to ionization to generate ozone, causing secondary pollution; the filtering effect of activated carbon adsorption is affected by the use time and particle size, and after work As solid waste, activated carbon needs to be further treated, and there is also a hidden danger of secondary pollution. At present, electret is mostly used, but the common electret has poor timeliness, and the charge storage degree is weak and decays quickly. At present, many manufacturers of meltblown materials Fluorine organic micropowder is added as an electret synergist, the effect varies from product to product, and the electric field stability is poor, so it can only be used as a consumable. For air purifiers or air-conditioning fresh air systems, the design is stable and efficient Electret material is very necessary
