Problems solved by technology

[0005] The application of existing negative oxygen ions is mainly through mixing with paint, latex and other solutions, and applying them to building wall materials through post-processing methods such as scraping and spraying. This method uses chemicals such as paint, which leads to the disadvantage of poor environmental protection.
In addition, due to the fast pace of life and work, modern people are prone to beriberi and sweat stains, which breed bacteria and affect the skin health of the feet. The existing midsole material base material is made of polyester fiber material, which has poor moisture absorption and perspiration performance. shortcoming
[0006] In order to allow people to enjoy the various benefits brought by negative oxygen ions, many patented technologies currently disclose methods such as blending polyester staple fibers with negative oxygen ions and other fibers, so that based on the presence of negative oxygen ion polyester staple fibers , so it can produce negative oxygen ions to a certain extent, but because the negative oxygen ion polyester staple fiber is formed by adding nano-scale negative oxygen ion powder in the melt extrusion process of staple fiber production, it is formed through the short fiber production line, which is subject to short fiber production. Process technical limitations, negative oxygen ion addition ratio is not high, its emission is low, the actual effect is not ideal

Abstract

The present invention discloses an environment-friendly antibacterial composite material and a manufacturing method thereof. The environment-friendly antibacterial composite material comprises regenerated polyester staple fibers of which the fineness is 2.0 D, the length is 51 mm and the content is 30-50 wt%, regenerated polyester staple fibers of which the fineness is 2.5 D, the length is 64 mm and the content is 25-40 wt%, and bamboo pulp fibers of which the fineness is 2.0 D, the length is 51 mm and the content is 25-35 wt%. A finishing liquid of the environment-friendly antibacterial composite material in a finishing process is composed of the following components of 20-30 parts by weight of a high polymer emulsion, 10-20 parts by weight of starch, 25-35 parts by weight of coarse whiting, 40-50 parts by weight of clean water, and 3-5 parts by weight of negative oxygen ion powder. Through plates commonly manufactured by the bamboo pulp fibers and negative oxygen ions, the composite material has a bacteriostatic action and also an obvious smell-removing function.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an environment-friendly antibacterial composite material and a preparation method thereof, which can be applied to building wall materials or shoe midsole base materials. Background technique [0002] Bamboo fiber has natural antibacterial properties and adsorption properties, and has no side effects. It is the preferred raw material for natural antibacterial products. The production process of bamboo pulp fiber is similar to that of viscose fiber, that is, bamboo cellulose is dissolved by chemical solvents, and then Obtained by wet spinning. [0003] Air is composed of various molecules. Due to the influence of natural cosmic rays, ultraviolet rays, soil and air radiation, some molecules in the air release electrons and anions. Most of the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. There...
