Abstract

The invention relates to a preparation method of puncture-proof coating aramid fabric. The preparation method of the puncture-proof coating aramid fabric is characterized by comprising the steps of preparing a dispersing agent first, grinding copper powder into nanometer particles and then dissolving nanometer copper particles into the dispersing agent to prepare a nanometer copper particle dispersion; polymerizing and emulsifying monomers such as acrylic acid, butyl acrylate and styrene to prepare a polyacrylate emulsion; compounding the nanometer copper particle dispersion and the polyacrylate emulsion to prepare a nanometer copper particle / polyacrylate composite emulsion; and carrying out coating finishing on aramid fabric by using the emulsion to prepare the puncture-proof coating aramid fabric. The puncture-proof coating aramid fabric prepared by the preparation method of the puncture-proof coating aramid fabric, provided by the invention, has the advantages that obvious puncture-proof performance is realized; other various indexes of the puncture-proof coating aramid fabric are almost approximate to various indexes of market-purchased coating aramid fabric; each index of thepuncture-proof coating aramid fabric is not obviously reduced after being washed by water for 10 times; and therefore, it is shown that the stability and durability of the puncture-proof coating aramid fabric are both very good.

Description

technical field [0001] The invention belongs to the technical field of stab-resistant fabrics, and in particular relates to a preparation method of a stab-resistant coated aramid fiber fabric. Background technique [0002] With the rapid development of society, some international terrorist incidents occur from time to time, which promote the development of personal protection technology. Although many countries, including China, have implemented strict controls on knives, some violent incidents related to knives have occurred from time to time, so the research and development of stab-resistant clothing has received extensive attention. Stab-resistant clothing is required to meet the requirements of stab-proof and wearable. With the improvement of people's requirements for the anti-stab performance of clothing, there is an urgent need for anti-stab clothing with good concealment, high comfort and low price. In terms of stab-resistant clothing materials, aramid fibers are wi...
