Embodiment 1

[0019] The synergistic woven fabric (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 an areal density of 185g / m 2 The ultra-high molecular weight polyethylene fiber non-weft cloth containing acrylate resin is cut into a rectangle of 250mm×300mm. Laminate 36 layers of ultra-high molecular weight polyethylene fiber non-weft cloth and 1 layer of synergistic 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, 80°C After preheating, 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 ...

[0021] The synergistic woven fabric (ultra-high molecular weight polyethylene fiber and glass fiber volume ratio 70:30, surface density 250g / m 2 , coated with 40g / m on one side 2 polyethylene film) and an areal density of 185g / m 2 The ultra-high molecular weight polyethylene fiber non-weft cloth containing polyethylene resin is cut into a rectangle of 250mm×300mm. Laminate 47 layers of ultra-high molecular weight polyethylene fiber non-weft cloth and 1 layer of synergistic 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, 80°C After preheating, 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 7mm thick silicon carbide ceramic plate, the other side is bonded to the buffer layer, and then the arami...

Embodiment 3

[0023] Synergistic woven fabric (high molecular weight polyethylene fiber and carbon fiber volume ratio 60:40, surface density 180g / m 2 , coated with 30g / m on one side 2 Acrylic film) and an areal density of 185g / m 2 The ultra-high molecular weight polyethylene fiber non-weft cloth containing acrylate resin is cut into a square of 500mm×500mm. Laminate 37 layers of ultra-high molecular weight polyethylene fiber non-weft cloth and 1 layer of synergistic 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, 80°C After preheating, it was hot-pressed at 120°C and 17MPa for 50 minutes, and then cooled to room temperature and taken out to become a laminated plate. Then apply glue on the side with the synergistic layer, bond it with a 9.5mm thick silicon carbide ceramic plate, and then glue an aramid crack arresting layer on the outside of the ceramic, cure it at 50°C for 6 hour...

Abstract

The invention provides a composite bulletproof plate containing an adhesive-bonding synergistic layer and a manufacturing method thereof. According to the composite bulletproof plate containing the adhesive-bonding synergistic layer, the adhesive-bonding synergistic layer 1 used for improving an adhesive-bonding effect is added on the surface to be adhered to ceramic, and the synergistic layer 1 is woven fabric obtained through mixing of ultra-high molecular weight polyethylene fibers and polarity fibers according to the mass ratio from 1:99 to 99:1. An adhesive film 2 is arranged on the woven fabric in a single coating mode, and the type of resin contained in ultra-high molecular weight polyethylene non-weft cloth is the same as the type of resin contained in the adhesive film. By combining with the manufacturing method of the composite bulletproof plate, the composite bulletproof plate containing the adhesive-bonding synergistic layer can overcome the defects that adhesive commonly used in the composite bulletproof plate is not good in wettability, and the composite strength between the ceramic and the composite bulletproof plate is poor in the prior art.

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 structure of the bulletproof plate widely used in practice mainly has two parts: 1. The panel, generally made of high hardness and high compressibility 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 bulletproof material, and it must be restrained and supported by sufficient backplanes to exert its excellent performance. Ballistic properties. The composite effect between the ceramic and the back plate directly affects the bulletproo...
