Problems solved by technology

When the surface of the substrate is nano-metallized, there are still some core technical problems. First, the number of nano-metal particles is insufficient and the adhesion of the coating is not strong, so that the various excellent functions of the material are not durable and sufficient; The distribution range is difficult to control and the distribution of nanoparticles is uneven, so that the nanoscale metal coating becomes a s

Abstract

The invention relates to a technology for total-cladding composite ion plating of the surface of an aramid fiber or laid fabric with nanometals. A substrate is the aramid fiber or the laid fabric made of the aramid fiber. The technology comprises the following steps: 1, carrying out dewatering degassing treatment on the substrate in a vacuum chamber with the vacuum degree of 10-3.0*10<-4>Pa and the heating temperature of 60-180DEG C; 2, carrying out plasma surface cleaning treatment on the substrate by adopting a cathode ion film plating device with argon or nitrogen as a protection gas under a vacuum degree of 1.0*10<-1>-3.0*10<-4>Pa at a temperature of -10 - -30DEG C under a substrate running speed of 3.0-10.0m/min, generating metal ions and nanoparticles with the density of 1.0-10.0g/m<2> in adopting a composite ion film plating mode with metals as a target material, and carrying out total-cladding plating on the surface of the substrate with a nanometal plating layer with the granularity of below 100nm; and 3, cutting the above obtained material, metering, and carrying out vacuum packaging. The technology greatly reduces the influences of water and ultraviolet ray on the aramid fiber, and greatly protects excellent mechanical performances of the aramid fiber.

Description

technical field [0001] The invention belongs to the field of functional textile materials, and in particular relates to a process of fully covering the surface of an aramid fiber or a weft-free fabric with composite ion-plating nanometer metals and its products. Background technique [0002] Because para-aramid has high strength and high modulus, and meta-aramid has the characteristics of high temperature resistance and permanent flame retardancy, aramid can be used to make advanced composite materials for aerospace, ships, automobiles, and bulletproof Products, special protective clothing, sports equipment and other products. [0003] However, aramid fibers have high crystallinity and smooth surface, lack of chemically active groups on the surface, and poor surface wettability. Due to the existence of a large number of aromatic rings in the molecular structure of aramid fibers, the hydrogen bonds between molecular chains are very weak, and the transverse The strength is on...
