Abstract

A method for preparing durable and anti-ultraviolet polypropylene fibers, comprising: adding titanium oxide powder and zinc oxide powder to a powder grinder for grinding; performing surface modification treatment; adding hydrophobic nano-silica powder and additives Mixing; kneading to obtain masterbatch; blending to obtain UV-resistant polypropylene; and melt spinning to obtain the durable UV-resistant polypropylene fiber. In the present invention, nano-titanium dioxide and nano-zinc oxide are selected. After the two are ground and mixed, they are modified with a silane coupling agent. The modified nano-titanium dioxide and nano-zinc oxide are further mixed with hydrophobic nano-silica powder. Hydrophobic nano-silica contains organic groups on the surface, so it has better interfacial compatibility with polypropylene; the three have a synergistic effect, showing good durability characteristics; the added additives and anti-ultraviolet powder Together with the body, it improves the anti-ultraviolet effect and improves the service life of the polypropylene fiber of the product.

Description

technical field [0001] The invention relates to the field of preparation of organic anti-ultraviolet materials, in particular to a preparation method of durable anti-ultraviolet polypropylene fibers. Background technique [0002] Ultraviolet rays are one of cosmic rays. Usually, ultraviolet rays can be divided into long-wave ultraviolet UVA (315-400nm), medium-wave ultraviolet UVB (280-315nm) and short-wave ultraviolet UVC (100-280nm) according to the wavelength band. Among them, ultraviolet rays are mainly composed of three parts: long-wave ultraviolet UVA (315-400nm), medium-wave ultraviolet UVB (280-315nm) and short-wave ultraviolet UVC (100-280nm). With the deterioration of the environment, especially the random use of a large number of freons worldwide, the serious damage to the ozone in the atmosphere has resulted in a sharp increase in the amount of ultraviolet radiation. [0003] Short-wave ultraviolet rays contain the highest energy and basically cannot reach the g...
