Bulletproof material introduced with thermosetting epoxy resin and preparation method thereof

Abstract

The invention provides a bulletproofing material with thermoset epoxy resin and a preparation method thereof and belongs to the fields of polymer composites and armor protection. The bulletproofing material is a composite formed by combining matrix resin and fiber. The matrix resin is prepared from, by weight, 10-20 parts of polyvinyl butyral, 1-10 parts of epoxy resin, 50-85 parts of diluents, 1-10 parts of a curing agent and 0.6 part of auxiliaries. The epoxy resin is selected from one or any combination of two or more of bisphenol A type epoxy resin E-51, E-44 and E-20, bisphenol F type epoxy resin NPEF170, phenolic aldehyde type epoxy resin F-44 and F51 and polyfunctional group epoxy AG-80. The bulletproofing material can ensure the bearing strength and the bulletproofing performance and has the advantages of being light, good in softness and comfortable to wear when the bulletproofing material is used for body armors; when the bulletproofing material is used for bulletproofing armors, rigidity can be improved, and the weight of the bulletproofing armors can be reduced, and therefore the bulletproofing material has wide application value.

Description

technical field [0001] The invention relates to a bulletproof material and a preparation method thereof, in particular to a composition resin of polyvinyl butyral and epoxy resin, which is applied to fiber composite materials for bulletproof, and belongs to polymer composite materials and armor protection field. Background technique [0002] Since World War II, the development of bulletproof materials has been changing with each passing day. Especially in recent years, the world's anti-terrorism situation is severe, and human beings have strengthened their own safety protection awareness. The development of bulletproof materials is particularly important. It can be divided into three types according to different materials. The first type is hard body armor, which is made of steel plates or ceramic plates. Or shrapnel, it is inconvenient to wear and move, it is cumbersome and cannot protect the whole body, and has irreparable shortcomings. The second type is soft bulletproo...

Problems solved by technology

Soft body armor is easy to loose without restraint

The third type is soft and hard composite body armor. Its base is soft body armor. In the reserved interlayer, ceramic plates or metal material composite plates are added as internal reinforcement materials, which are bulky and not conducive to wearing.

Generally, thermoplastic resins such as polyurethane elastomer TPU or polyvinyl butyral PVB are used in bulletproof materials, which have the advantages of good flexibility and good mechanical relaxation, but they show insufficient rigidity in bulletproof materials with special armor structures. Disadvantages of insufficient fiber adhesion

The present invention introduces thermosetting epoxy resin into the bulletproof material, which not only endows the material with the characteristics of light weight, softness, good flexibility, and high strength, but also has no relevant reports at home and abroad.
