Abstract

The invention discloses a flame-cutting-resistant composite coating bulletproof steel plate. The composite coating bulletproof steel plate comprises a flame-retardant layer, a thermal barrier layer, abulletproof steel plate layer and a heat insulation layer which are overlapped in sequence. Compared with the prior art, the composite coating bulletproof steel plate has the advantages that the structural strength is guaranteed through the bulletproof steel plate layer, then an insulating layer is formed through the flame-retardant layer, the flame-cutting-resistant capacity is improved, in addition, the heat insulation layer reduces the influence degree on the high temperature and flame, and the heat conduction efficiency is reduced through the thermal barrier layer; and through cooperationof the flame-retardant layer, the thermal barrier layer and the heat insulation layer, the performance of flame-cutting-resistant can be synergistic.

Description

technical field [0001] The invention relates to the technical field of bulletproof steel plates, in particular to a flame cutting-resistant composite coated bulletproof steel plate. Background technique [0002] Bulletproof steel plates are generally used in bulletproof and explosion-proof projects, such as bulletproof doors, bulletproof helmets, bulletproof vests, bulletproof shields; bank counters, confidential safes; riot vehicles, bulletproof cash transport vehicles, armored personnel carriers, chariots, submarines, landing craft , anti-smuggling boats, helicopters, etc. [0003] The main technical improvement of the bulletproof steel plate lies in its structural strength and thickness. Generally speaking, the greater the thickness, the greater the structural strength. However, the thickness of the bulletproof steel plate is too large to be convenient for application, so now it is mainly to ensure the strength of the bulletproof steel plate. In the case of structural st...
