Abstract

The invention discloses an anti-radiation and shock-resistant polycarbonate sheet for a protective window and a preparation method of the polycarbonate sheet. The anti-radiation and shock-resistant polycarbonate sheet is prepared from raw materials in parts by weight as follows: 120-130 parts of polycarbonate, 10-12 parts of graphene nanofibers, 3-5 parts of dialkyl cyclohexanedicarboxylate, 10-14 parts of cyclic butylene terephthalate, 8-10 parts of a tetrafluoroethylene-hexafluoropropylene copolymer, 5-7 parts of dihydroxyaluminium stearate, 10-12 parts of an acrylonitrile-styrene-acrylate copolymer, 6-8 parts of oxidized paraffin, 5-7 parts of triisononyl trimellitate, 6-8 parts of flocking powder, 2-4 parts of dipentaerythritol hexacarboxylate and the like. Through blending of cyclic butylene terephthalate, the tetrafluoroethylene-hexafluoropropylene copolymer and the like with polycarbonate, the toughness, the abrasion resistance, the chemical stability, the impact strength and the radiation resistance of the sheet are improved, polycarbonate is modified with the raw materials including the flocking powder, the graphene nanofibers, magnesium oxide whiskers and the like, so that the anti-radiation performance and the shock resistance of the sheet can be improved, and the sheet has very high shock resistance and anti-radiation performance.

Description

field of invention [0001] The invention relates to a polycarbonate material, in particular to a radiation-proof and impact-resistant polycarbonate plate for protective windows and a preparation method thereof. Background technique [0002] Polycarbonate is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Due to the aliphatic and aliphatic-aromatic The mechanical properties of polycarbonate are low, so its application in engineering plastics is limited. At present, only aromatic polycarbonate has been industrialized. Polycarbonate has become the fastest growing general-purpose project among the five engineering plastics. plastic. [0003] The three major application areas of polycarbonate plastics are glass assembly industry, automobile industry and electronics and electrical industry, followed by industrial machinery part...
