High-strength composite fiber non-woven cloth and preparation method thereof

Abstract

The invention discloses high-strength composite fiber non-woven cloth and a preparation method thereof. Ultrahigh-strength high-modulus polyethylene fibers are used as base materials, the polyethylene fiber obtained after fiber placement is subjected to a series of homogenization, parallelization and straight and upright arrangement and placed in a modified epoxy resin solution for sizing treatment in an environment of 60-80 DEG C, then the formed polyethylene fiber layers are subjected to composite lamination, and the non-woven cloth is prepared, wherein the modified epoxy resin solution is prepared by adding and mixing an adhesion agent, a filling agent, an insulating filler, fire retardant, white carbon black and ethyl alcohol, the mass of hydroxyl chemigum accounts for 8-12% of the mass of the modified epoxy resin solution, and the content of vinyl cyanide accounts for 18-30% of the content of hydroxyl chemigum. The non-woven clothes with different thicknesses are prepared by lamination of the polyethylene fiber layers, an antiknock device can be made from different types of non-woven cloths according to explosion sites and use environment, and the non-woven cloths with different thicknesses are different in anti-explosion range so as to sufficiently withstand the impact of a bullet.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-strength composite fiber non-weft cloth and a preparation method thereof. Background technique [0002] The high-performance fiber "UD" non-weft fabric is made of ultra-high-strength and high-modulus polyethylene fiber as the base material. It is uniformly laid by advanced high-tech equipment, impregnated with high-strength elastomer resin, glued and bonded with film, and then 0° / 90º ; Bi-orthogonal composite laminated. The product has excellent properties such as soft hand feeling, low density, abrasion resistance, impact resistance, and strong cutting toughness. Linings and special public anti-riot facilities are the bulletproof materials with the highest strength and lightest specific gravity in the world today. Due to the late start of polymer material technology in my country, the technology is not mature enough, and the manufacture of non-woven fabrics is o...
