Problems solved by technology

[0005] Specifically, the present invention provides a method for preparing an air-clean filter fabric with a formaldehyde removal function, which solves the problem that formaldehyde molecules in the air and bacteria and viruses brought in cannot be effectively removed by making a filter device or filter bag from the fabric. Vinyl alcohol is loaded on the filter material as a remover, so that formaldehyde in the air forms a polycondensation reaction with the hydroxyl groups contained in the coating when it passes through the filter fabric, realizing the rapid removal of formaldehyde, and the flocculent silica gel improves the coating viscosity of the coating. At the same time, the synergistic effect of nano-rod zinc oxide and titanium dioxide catalysts with composite silver ions is used to endow the filter fabric device or filter bag with the environmental protection function of decomposing formaldehyde and purifying air for a long time

Abstract

The invention belongs to the field of textile materials, and particularly relates to a preparation method of an air purification filter fabric with a formaldehyde removal function. The preparation method comprises the following steps: preparing a fabric treatment agent which is prepared from powder and a liquid preparation and preparing a formaldehyde catalytic decomposition agent, wherein specific components and formulas of the fabric treatment agent and the formaldehyde catalytic decomposition agent are provided; uniformly coating the surface of a fabric with the prepared fabric treating agent and the formaldehyde catalytic decomposition agent in sequence; and carrying out heat treatment in a drying oven. According to the invention, polyvinyl alcohol is used as a removing agent to be loaded on a filtering material, so formaldehyde in air and hydroxyl contained in a coating undergo condensation polymerization when passing through the filtering fabric, and rapid removal of formaldehydeis achieved; flocculent colloidal silica improves the adhesion strength of the coated coating; and meanwhile, by utilizing the synergistic effect of nano-rod-shaped zinc oxide compounded with silverions and a titanium dioxide catalyst, a filtering fabric device or a filtering bag is endowed with the environment protection functions of permanently decomposing formaldehyde and purifying air.

Description

technical field [0001] The invention belongs to the field of textile materials, and in particular relates to a method for preparing an air-clean filter fabric with formaldehyde removal function. Background technique [0002] Formaldehyde is a colorless gas with a pungent odor, easily soluble in water, alcohol and ether. Formaldehyde has a wide range of uses in industry. It is often used in textiles, dyes, leather, resins, paints, plastics, rubber, pharmaceuticals, explosives, etc. Therefore, formaldehyde pollution mainly comes from the above products. The harm of formaldehyde to the human body is mainly manifested in the following aspects: formaldehyde can combine with the protein in the protoplasm of somatic cells, change the internal structure of the protein and solidify, so it has biocidal power. At low concentrations, it initially irritates the mucous membranes of the eyes, and at high concentrations, it irritates the upper respiratory tract, causing coughing, chest t...
