A kind of preparation method of flame retardant bulletproof composite material and prepared composite material

Abstract

The invention discloses a preparation method for flame-resistant bulletproof composite material and the prepared composite material. The preparation method comprises: uniformly mixing a catalyst, a carbonization agent and a foaming agent according to a mass ratio of 5:3:2, so as to prepare an expanded type composite halogen-free flame-retardant system; mixing the expanded type composite halogen-free flame-retardant system with a base body resin, so as to prepare a flame-resistant bulletproof composite base-body glue solution; then performing cross-ply composite forming on continuous fiber and the flame-resistant bulletproof composite base-body glue solution, and performing hot-air drying to prepare a flame-resistant bulletproof composite material preform; and finally performing hot-pressing forming on the flame-resistant bulletproof composite material preform to prepare the flame-resistant bulletproof composite material. According to the technical scheme, the composite material disclosed by the embodiment of the invention has good flame resistance, also has the bulletproof performance of a bulletproof material which is not added with a flame retardant in the prior art, also has the characteristics of being safe, environment-friendly, light in texture and the like, and helps to maximize the protection level of various bulletproof equipment.

Description

technical field [0001] The invention relates to the field of flame-retardant bulletproof composite materials, in particular to a method for preparing a flame-retardant bulletproof composite material and the prepared composite material. Background technique [0002] With the rapid development of material composite technology, high-performance fiber-reinforced composite materials are widely used as bulletproof materials on bulletproof equipment such as individual bulletproof vests, bulletproof inserts, and bulletproof armor. However, the flame retardancy of existing bulletproof materials is poor; in order to maximize the protection capability of personal protective equipment and bulletproof armor, improving the flame retardancy of existing bulletproof materials has become an urgent problem to be solved.

However, the flame retardancy of existing bulletproof materials is poor; in order to maximize the protection of personal protective equipment and bulletproof armor, improving the flame retardancy of existing bulletproof materials has become an urgent problem to be solved

[0003] In the prior art, there are generally two ways to improve the flame retardant performance of bulletproof materials: one method is to improve the flame retardant performance by improving the structure of bulletproof materials, for example: adding flame retardant structures on the basis of existing bulletproof materials (For example: aluminum foil) to improve the overall flame retardant performance, but this method does not essentially improve the flame retardant performance of the bulletproof material, and greatly increases the overall weight of the material; another method is to prepare bulletproof materials. Adding a flame retardant system to the matrix of the bulletproof material to improve the flame retardant performance, but the flame retardant system that can be added to the matrix of the bulletproof material in the prior art is mostly a halogenated flame retardant system, and the halogenated flame retardant system will bring environmental harm. Serious negative impact; recently, individual manufacturers have developed a halogen-free flame retardant system that can be added to the matrix of bulletproof materials, but its flame retardant performance is poor, and the original bulletproof performance of bulletproof materials is reduced
