Problems solved by technology

[0003] Compared with coatings, floors, glass, ceramics and other materials, photocatalytic multifunctional fiber materials have a larger specific surface area, so they can fully contact with organic pollutants in the air, and can eliminate organic pollution in the air more quickly and efficiently substances, reducing heavy metal inorganic ions, sterilizing and deodorizing, etc., but currently there are very few fiber materials with this function, and the few fiber materials have low organic matter decomposition rate and bacterial inhibition rate, which are harmful to human health. less than great benefit

Abstract

The invention relates to a photocatalytic multifunctional fiber material and a preparation method thereof, belonging to the technical field of materials. The invention mainly solves the technical problems that the decomposition rate of organic matters of the exiting fiber materials is low, the sterilizing and bacteriostatic effect is not obvious and the like. The fiber material is formed by polypropylene master batches and polypropylene slices. The preparation method comprises the following steps: converting tungstate into colloid; using rare earth oxide to prepare rare earth nitrate mixed solution; adding the colloid into the rare earth nitrate mixed solution and dripping dilute acid to form sol; adding catalyst promoter material in the sol to obtain wet gel; after drying and sintering the wet gel, conducting ultrasonic dispersion to obtain powder; adding dried polypropylene matrix, dispersing agent, coupling agent and defoaming agent in the powder and preparing polypropylene master batches through a screw extruder; and adding polypropylene slices in the polypropylene master batches and preparing the photocatalytic multifunctional fiber material through the screw extruder, a melt spinning technology and a deformation technology. The invention has the advantages of high organic matter decomposition rate, good sterilizing effect and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental purification materials, and in particular relates to a photocatalytic multifunctional fiber material and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, people have put forward higher requirements for the quality of life. People's purchase of houses, room decoration, and the application and promotion of petroleum, coal, natural gas, chemical products, automobiles, etc., have brought a certain degree of pollution to our indoor and outdoor air while improving our living standards, especially in recent years. Increasingly luxurious, indoor and outdoor air pollution caused by extensive use of household chemicals, smoking, cooking and other human activities can no longer be ignored, and the quality of the environment directly affects people's health. For people's health, people invented photocatalysis Tech...
