Problems solved by technology

Such a device is relatively complicated and expensive, but the glued HSHM-PE fiber is very easy to stick to the lining film, causing difficulty in separation, which means that the initial product of UD material is a two-layer compound [0° / 90°] (with PE protective film on both sides) appears, according to this process, if you want to implement four-layer composite [0° / 90°] 2 (PE protective film on both sides) It is very difficult to produce standard products

Embodiment

[0032] Use ZTX99 400f high-strength high-modulus polyethylene fiber (1) (strength ≥ 35g / d, fineness 2.0-2.5d), pass through 3 reed / cm reed (2) and tension frame (3), and then rub with polygonal prism roller (4) Friction, the friction roller (4) can be made of chromium oxide, magnesium oxide or aluminum oxide material, or a layer of chromium oxide, magnesium oxide or aluminum oxide material can be coated on the surface of the roller made of other materials. The surface layer of the friction roller (4) used in the embodiment is coated with magnesium oxide to generate high-voltage static electricity and spread the fibers evenly. Fibers carrying high-voltage static electricity are statically eliminated by static eliminator (5) before being glued, then transferred to glue roller (10), and glued at glue point (9). The adhesive used in this embodiment is KRATON G- 1650 is dissolved in mixed solvent (hexane: diethyl ether: ethyl acetate = 5: 0.5: 1, then add terpene resin and antioxid...

Abstract

A high-strength and-modulus single-orientation preimmersed band of polyethene fibres used for bullet-proof vest is prepared through uniform spreading in parallel mode, adhering with the adhesive having high solidifying speed to obtain band, and alternative overlapping to obtain target UD material.

Description

technical field [0001] This instruction is about the continuous preparation of high-strength and high-modulus polyethylene fiber unidirectional prepreg tape, which belongs to the polymer category. Background technique [0002] The composite material (hereinafter referred to as UD material) made of high-strength high-modulus polyethylene (HSHM-PE) fiber unidirectional prepreg tape through interlacing compounding is a novel composite material, which is made of HSHM-PE (or aramid fiber, PBO fiber ) After being uniformly, parallel, and straightly arranged into a continuous strip, it is impregnated and dried to obtain a continuous prepreg strip of single-oriented fibers, and then the above prepreg strips are interlaced and compounded to make corresponding fibers UD material. [0003] UD material was founded in the 1980s by the High Performance Fiber Technology Center of Allied Signal’s Company in the United States. It is aimed at the defects of fabrics used in bulletproof produc...
