Abstract

The invention discloses a thermosetting membrane for the adhesion of bulletproof fiber and a processing method of the thermosetting membrane, and belongs to the field of high-molecular materials. The thermosetting membrane is prepared from the following materials in parts by weight: at least (a) 40-50 parts of film-forming resin, (b) 13-15 parts of plasticizing agents for the film-forming resin, (c) 30-45 parts by weight of curable resin, (d) 5-10 parts of cured resin curing agents and (e) 0.05-2 parts of surface treating agents. The method disclosed by the invention can be used for preparing the thermosetting membrane with good film-forming property, the uniform accuracy of +/- 0.001 mm, the crosslinking degree less than 5% and the thickness of 0.05-0.2 mm, has the advantages of simple preparation process, no solvent volatilization, good sizing uniformity, uniformity in interface adhesion, and the like and fundamentally overcomes the defects of low production efficiency, serious environment pollution, poor sizing uniformity, product fiber embrittlement and the like which are brought by using a wet method process of a liquid adhesive material. The thermosetting membrane disclosed by the invention is mainly applied to the adhesion of single materials, namely bulletproof aramid fiber materials, carbon fibers and the like, or composite materials and is applied to the fields of aviation, war industry, civil use and the like in production of bulletproof clothes, bulletproof helmets and the like.

Description

technical field [0001] The invention relates to a method for processing and preparing a polymer film material, in particular to a production process for a heat-cured film used for bulletproof fiber bonding, and belongs to the field of polymer materials. Background technique [0002] In recent years, with the rapid development of my country's national economy, especially the complex and multi-international environment, the aviation industry and military industry have developed particularly rapidly, and the research and development of new materials to replace traditional materials has become a hot spot. The application of light composite materials instead of steel plates has been gradually launched in the fields of aerospace, aviation, and bulletproof, especially in bulletproof composite materials and products. Lightweight composite bulletproof materials, including bulletproof vests, bulletproof helmets, and bulletproof targets, are all made of multi-layer laminated materials ...
