Abstract

The invention relates to the technical field of material preparation, in particular to a preparation method of an all-polyolefin bulletproof composite material. Comprising the following steps: S1, preparing raw materials; s2, plasticizing the raw materials; s3, composite forming; s4, cooling; s5, carrying out post-treatment; s6, spreading the yarn; and S7, cutting application: after the prepared all-polyolefin unidirectional film is cut by a certain size, orthogonally overlapping a certain number of layers at 0 / 90 degrees, and molding in a heating mold pressing manner to obtain the all-polyolefin bulletproof composite material. The problem that a conventional UHMWPE fiber bulletproof composite material is low in bulletproof performance due to the fact that the interface cohesiveness between the PE fiber and the heterogeneous resin matrix is insufficient is solved, and the composite material is lower in density and more prominent in light weight advantage.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a preparation method of an all-polyolefin bulletproof composite material. Background technique [0002] Bulletproof vests, also known as bulletproof vests, bulletproof vests, bulletproof vests, bulletproof clothing, etc., are individual body protection equipment, which is used to protect the human body from warheads or shrapnel; bulletproof shields are used to form an array to protect warheads and shrapnel. The damage to the human body greatly improves the survivability of the Corps in combat. [0003] As an enhanced product of individual protective equipment, PE board is usually used in conjunction with bulletproof vests. The test methods for the protection level of PE board include two kinds of testing methods: with clothes test and single-proof test. After the suits are put together, the protection test work is carried out. The single protection refers to the pro...
