Abstract

The invention discloses filter cloth with an antibacterial function. The filter cloth comprises the following raw materials in parts by weight: 30-40 parts of glass fibers, 15-25 parts of modified banana fibers, 10-20 parts of silver fibers, 6-10 parts of graphene, 8-14 parts of modified diatomite, 5-11 parts of modified vegetable oil, 6-12 parts of nanometer silica powder, 3-5 parts of sodium palmitate, 2-5 parts of rare earth lanthanum chloride and 20-30 parts of deionized water. The banana fibers of the filter cloth have antibacterial properties, the silver fibers also have antibacterial properties, the surface energy of the banana fibers is improved after modification treatment, the antibacterial properties of the material can be further improved by the silver fibers, the connection among the raw materials is tighter due to the addition of the modified diatomite and the modified vegetable oil, and the performance of the material is further improved due to the interaction of the rawmaterials.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a filter cloth with antibacterial function and a preparation method thereof. Background technique [0002] Filter cloth is a filter medium made of natural fibers or synthetic fibers. Commonly used materials include cotton, hemp, wool, cocoon silk, asbestos fibers, glass fibers and some synthetic fibers. For example, cotton woven canvas, twill and woolen woolen cloth, etc., including metal mesh or filter mesh; mainly used in air filtration and dust removal, dust collection, to purify the air, protect the environment, in smelters, chemical plants, sugar , dyes, medicine, food and other industries, according to the shape of the cross-section of the dust filter bag, it is divided into: flat bag (trapezoid and flat shape) and round bag (cylindrical shape), according to the way of air inlet and outlet: bottom air inlet and upper outlet Wind, upper air inlet, lower air outlet and ...
