Ultrahigh molecular-weight polyethylene fiber braided fabric for field protection

Abstract

The invention discloses an ultrahigh molecular-weight polyethylene fiber braided fabric for field protection. The ultrahigh molecular-weight polyethylene fiber braided fabric for field protection comprises a composite layer, and polyurethane lines which are knitted around the composite layer, wherein the composite layer is prepared by compounding ultrahigh molecular-weight polyethylene fiber layers and carbon fiber layers; a plurality of knitting blocks which are knitted through the polyurethane lines are arranged on one side of the composite layer; the surface of the braided fabric is coatedwith a high-temperature-resistant nano coating; the ultrahigh molecular-weight polyethylene fiber layer is subjected to surface treatment, namely, polyethylene chain of the ultrahigh molecular-weightpolyethylene fiber layer is grafted with an acrylic acid monomer and acrylonitrile, and the grafted acrylonitrile is subjected to amidoximation and then is chelated with metal ions. The braided fabricwhich is of a three-dimensional structure is high in intensity, high in elastic modulus, high in shearing modulus, high in long-term high-temperature resistance and corrosion resistance, outstandingin abrasion resistance, and hard to age; meanwhile, the modified ultrahigh molecular-weight polyethylene fibers are high in moisture absorption, breathability, flame retarding performance and antibacterial performance.

Description

technical field

[0001] The invention relates to a high-strength braided fabric, in particular to an ultra-high molecular weight polyethylene fiber braided fabric for field protection. Background technique

[0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is one of the three high-tech fibers in the world today. It has many excellent properties, such as high strength, high modulus, light weight, stable chemical properties, wear resistance and bending resistance, and cut resistance. etc. It is an ideal material for national defense fields such as aerospace, bullet-proof and stab-proof, and civil fields such as mooring ropes and labor protection supplies in offshore oil fields.

[0003] With the prosperity of the country and the continuous improvement of people's living standards, more and more people begin to pursue the enjoyment of spiritual life. Many people choose to travel, field adventure, camping and other outdoor activities to find stimulation or relax. H...
