Embodiment 1

[0019] Woven cloth (ultra-high molecular weight polyethylene fiber and aramid fiber 1414 fiber volume ratio 50:50, surface density 200g / m 2 , coated with 30g / m on one side 2 Acrylic film) and areal density of 185g / m 2 The UHMWPE fiber non-weft cloth containing acrylate resin is cut into a rectangle of 250mm X 300mm. Laminate 36 layers of ultra-high molecular weight polyethylene fiber non-weft cloth and 1 layer of woven fabric. The synergistic woven fabric is placed on the side that will be bonded to the ceramic, and the side without the adhesive film is facing outward. Preheat at 80°C Afterwards, it was hot-pressed at 120°C and 17MPa for 50 minutes, and then cooled to room temperature and taken out to become a single-curved laminate. Then apply glue on both sides, the side with the synergistic layer is bonded to the 9.5mm thick silicon carbide ceramic plate, the other side is bonded to the buffer layer, and then the aramid crack arresting layer is bonded to the ceramic surfa...

Abstract

A composite bulletproof board containing an adhesive synergistic layer and a preparation method thereof, characterized in that the composite bulletproof board containing an adhesive synergistic layer is to be bonded with ceramic Add a layer of synergistic layer to improve the bonding effect on one side. The synergistic layer is a woven fabric made by mixing ultra-high molecular weight polyethylene fibers and polar fibers in a mass ratio of 1:1 to 99:1. And the woven fabric is coated with the same type of resin as the ultra-high molecular weight polyethylene non-woven fabric 2 on one side. Combined with its preparation method, it can overcome the defects in the prior art that it has poor wettability with commonly used adhesives and poor composite strength between ceramics and it.

Description

technical field [0001] The invention belongs to the technical field of bulletproof boards, and in particular relates to a composite bulletproof board with an adhesive synergistic layer and a preparation method thereof. Background technique [0002] At present, the bullet-proof plate structure widely used in practice mainly has two parts: 1, the panel, generally uses high hardness, high-strength compressive materials, such as: alumina ceramics, silicon carbide ceramics, boron carbide ceramics, etc.; 2, the back plate, generally It is a high-performance fiber-reinforced resin-based composite material, such as: aramid fiber, ultra-high molecular weight polyethylene, etc.; due to its brittleness, the ceramic sheet cannot be used alone as a bullet-proof material. Ballistic properties. The composite effect between the ceramic and the back plate directly affects the bulletproof effect of the composite bulletproof plate. For the backsheet made of ultra-high molecular weight polyet...
