Description
Technical field
The present invention relates to a kind of preparation for processing of macromolecule member material, be specifically related to a kind of production technique for the bonding use of ballistic fiber heat cured film, belong to polymeric material field.
Background technology
In recent years, along with the fast development of Chinese national economy, especially the complexity of international environment is handed over more, and aircraft industry, war industry develop particularly rapid, and the research and development that novel material substitutes traditional material have become focus.The application that lightweight composite materials substitutes steel plate launches gradually in space flight, aviation, shellproof field, particularly is applied in ballistic composite and goods.Comprise that the lightweight bulletproof composite materials such as flak jackets, bulletproof halmet, shellproof target are all that the layer laminates that adopts the single or multiple matrix materials such as shellproof aramid fiber material, carbon fiber, glass fibre, stupalith, metallic substance to prepare processes, when being subject to powerful impact, appropriate deformation and layered effect will be produced, the impact function of dissipation and transmission bullet, can effectively stop penetrating of alluvium.
At present, the domestic shellproof glue-applying technique of weaving cotton cloth all adopts the glue-applying techniques such as the wet method glue spraying, blade coating, preimpregnation, hand paste of liquid adhesives, this class technique circuit is long, production efficiency is low, need carry out the solvent seasoning devolatilization, bring the problems such as environmental pollution, maximum defect is that wet method gluing meeting makes glue enter the fibrous inside of weaving cotton cloth, and causes the applying glue uniformity coefficient poor; Simultaneously, make the fiber hardening after glue curing, and lose the snappiness of weaving cotton cloth, ballistic performance is descended.
At present, adopt in the world the dry method glue-applying technique of heat cured film to prepare the bulletproof composite material and gradually become trend, this technique can fundamentally solve the defect that the wet processing that uses the liquid adhesives brings, and has manufacture craft simple, significantly improves production efficiency; Without drying process, solvent-free generation, stop environmental pollution; Maximum characteristics are that applying glue good evenness, bonding interface are even, make adhesive layer clear with the separation of weaving cotton cloth, and avoid Resin adhesive to enter the fibrous inside of weaving cotton cloth, thus performance adhesive layer and the efficiency of weaving cotton cloth separately.
The Patents of the heat cured film still do not used for mould pressing process in the world at present, the formula of grasp heat cured film and the technical information of process for processing technology are still in maintaining secrecy.
Summary of the invention
In order fundamentally to have solved, the production efficiency that in the prior art, the wet processing of use liquid adhesives brings is low, the defects such as environmental pollution large, the applying glue uniformity coefficient is poor, goods tendering of fiber.The purpose of this invention is to provide a kind of prescription and technique that can substitute the heat cured film for mould pressing process of liquid adhesives.The good film-forming property of the heat cured film that utilizes prescription of the present invention and technique to make, evenly precision is at positive and negative 0.001mm, degree of crosslinking is less than 5%, thickness is 0.05～0.2mm, described preparation technology has the advantages such as simple, the solvent-free volatilization of manufacture craft, applying glue good evenness, bonding interface be even, this heat cured film can be applied to the bonding of the single-material such as shellproof aramid fiber material, carbon fiber or matrix material, therefore can be widely used in producing the aviations such as flak jackets, bulletproof halmet, military project and the field such as civilian.
