Embodiment 1

[0037] This embodiment provides a lightweight bulletproof composite anti-destruction board for vehicles, the process is as follows figure 1 As shown, the composite anti-destruction board is made of UHMWPE fiber material and adhesive.

[0038] In this embodiment, the UHNWPE fiber has a fineness of 1100-1200D and a strength of not less than 35cn / dten.

[0039] In this example, the modulus of the ultra-high molecular weight polyethylene fiber is 1470 cn / dtex.

[0040] In this example, the adhesive uses acrylic acid modified water-based polyurethane glue, and the specific preparation method is as follows:

[0041]By adding polytetramethylene ether glycol PTMEG, 2,2-dimethylolpropionic acid (DMPA), 1,4-dihydroxybutane, dicyclohexylmethane-4,4-diisocyanate (HMDI), Accurately weigh and add to the reaction kettle one by one, start stirring, slowly heat the mixture in the reaction kettle to 70.0°C, and then add 2 drops of catalyst;

[0042] The temperature of the reaction kettle is ...

Abstract

The invention discloses a light bulletproof composite destroy-resistant plate for a vehicle. The composite destroy-resistant plate is prepared by compounding a UHMWPE fiber material and an adhesive. The invention further relates to a preparation method of the light bulletproof composite destroy-resistant plate for the vehicle. The preparation method is simple and easy to implement, and the prepared destroy-resistant plate is light in weight, high in environmental adaptability, high in protection performance and small in depth of concavity; and the maneuvering performance and the effective loadof the vehicle are improved, and the safety of the vehicle and personnel is protected to the maximum extent.

Description

technical field [0001] The invention relates to an important protective equipment for armored vehicles, in particular to a lightweight bulletproof composite anti-destruction board for vehicles and a preparation method thereof, belonging to the technical field of polymer material development. Background technique [0002] Armored vehicles such as the Dongfeng Mengshi high-mobility off-road vehicle, in order to meet the requirements of bulletproof performance, are equipped with combat maneuverability when the armored vehicle is refitted, which requires protective equipment to realize it; The transition from simple synthetic materials to the development process of composite systems such as composite materials, metal armor plates, and ceramic shields. At present, the existing anti-destruction boards made of PE composite materials can resist Type 53 7.62 steel core bullets with a thickness of 20-25mm and a weight of 19.6-24.5kg / ㎡. The thickness is large and the weight is heavy. ...
