Problems solved by technology

Due to the use of adhesives, the manufacturing process of the composite bulletproof board becomes complicated. At the same time, because the adhesive is easy to age in a high temperature environment, the composite bulletproof board is easy to delaminate, resulting in a decline in the protective function of the composite bulletproof board.

Abstract

The invention discloses a fireproof heat-resisting PE (polyurethane) composite bullet-proof plate comprising a PE bullet-proof plate body. The fireproof heat-resisting PE composite bullet-proof plate is characterized in that a layer of inorganic fiber reinforced material is directly composited to a bullet face of the PE bullet-proof plate body, and adhesive is provided between the layer of inorganic fiber reinforced material and the bullet face of the PE bullet-proof plate body. The invention further discloses a production method of the fireproof heat-resisting PE composite bullet-proof plate. Compared with the prior art, the fireproof heat-resisting PE composite bullet-proof plate has the advantages that the plate is fireproof and heat resistant and to be specific, has a back face, composited in 10 minutes, the temperature of the back face rises only to 60 DEG C in the 1000 DEG C environment; the plate has thermal conductivity coefficient 0.03W / (m.K); the plate is waterproof and hydrophobic and has water absorption less than 0.05%; the plate is halogenation proof, nonhygroscopic and flooding resistant; the plate is crack resistant in long-term storage and has a shelf life over 5 years.

Description

technical field [0001] The invention relates to the technical field of bulletproof boards, in particular to a fireproof and heat-resistant PE composite bulletproof board and a preparation method thereof. Background technique [0002] The earliest Chinese patent on bulletproof panels appeared in the Chinese patent No. ZL92110800.1 filed by DSM Co., Ltd. on September 19, 1992, "a composite bulletproof panel composed of a layer of composite material and a layer of metal". The composite material layers used for the panels include fibers and a polymer matrix. [0003] Later, Chinese applicant Lu Yuyang submitted a patent on "combined transparent bulletproof plate" to the Chinese Patent Office on April 2, 1996. The Chinese patent number is ZL96103360.6. Polycarbonate LEXAN (MR5.XL) anti-smashing lighting panels are combined with glass. But this technology is no longer the mainstream of development in the field of bulletproof panels. [0004] Sun Lu, a Chinese applicant, submitt...
