[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 articles, and discloses curing agent reinforcement aramid fiber composite no-woven cloth and a preparation method and applications of the curing agent reinforcement aramid fiber composite no-woven cloth. The curing agent reinforcement aramid fiber composite no-woven cloth is made after silk is spread, aramid fiber is evenly, parallelly and straightly arranged, glued and dried, wherein curing agent is contained in an adhesion agent used in the process of gluing. The curing agent is trimethylolpropane triacrylate. The quantity of the added curing agent accounts 0.8-1.6% of the weight of the adhesion agent. The curing agent reinforcement aramid fiber composite no-woven cloth can overcome defects existing in the prior art to a large extent, not only changes heat stability of materials, improves anti-impact, bulletproof and anti-pricking performance of the aramid fiber composite no-woven cloth, but also can improve high-low-temperature performance of the aramid fiber composite no-woven cloth, and 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...
