Problems solved by technology

[0004] The Chinese patent application number 200910224262.5 discloses an aramid fiber non-weft fabric and its preparation method and application. The adhesive used in the gluing process contains aziridine curing agent, although it can improve the aramid fiber composite to a certain extent. The impact resistance, bulletproof and stab resistance of the non-weft fabric can also improve production efficiency, but it cannot improve the high and low temperature performance of the aramid fiber non-weft fabric

Abstract

The invention belongs to the field of bulletproof protective products, and relates to a curing agent-reinforced aramid fiber composite non-weft fabric and its preparation method and application. The aramid fiber is stretched and arranged evenly, parallelly and straightly, and then glued. , and made after drying, the adhesive used in the gluing process contains a curing agent; the curing agent is trimethylolpropane triacrylate, and the amount of the curing agent added is 0.8-1.6% of the weight of the adhesive. The curing agent-reinforced aramid fiber composite non-weft fabric of the present invention can overcome the defects existing in the prior art to a large extent, not only changes the thermal stability of the material, but also improves the impact resistance, bulletproof and thermal stability of the aramid fiber composite non-weft fabric Anti-stab performance, but also can improve its high and low temperature performance, and can also improve production efficiency.

Description

technical field [0001] The invention belongs to the field of bulletproof protective products, and relates to the improvement and preparation of an aramid fiber non-weft cloth, in particular to a curing agent-reinforced aramid fiber composite non-weft cloth and its preparation method and application. Background technique [0002] Aramid fiber non-weft fabric is made of aramid fiber through spreading, uniform, parallel and straight arrangement, and then it is glued and dried. The glued adhesives generally include polyethylene, cross-linked polyethylene, polypropylene, vinyl copolymer, propylene copolymer, ethylene-propylene copolymer and other olefin polymers and copolymers, as well as unsaturated polyester, polybutylene Diene, polyisoprene, natural rubber, epoxy resin, polyimide and many other low-modulus resins, in addition, there are EVA, EEA, SBS, SIS, TPR, SEBS and other sodium-butadiene rubber and styrene-butadiene rubber PVB, PVA, etc. these thermoplastic high tough gl...
