Abstract

The present invention discloses a biodegradable waterproof polycarbonate composite material and a preparation method therefor. The biodegradable waterproof polycarbonate composite material is prepared by using the following components in parts by weight: 80-90 parts of polycarbonate, 20-30 parts of polyvinyl acetate resin, 11-16 parts of hydroxypropyl methylcellulose, 8-15 parts of polyvinyl butyral, 3-7 parts of zirconium fluoride, 3-6 parts of 1,4-butanediol diacrylate, 2-5 parts of ethylene tetrafluoroethylene copolymer, 1-2 parts of 4,4'-bi (2, 2-epoxy propoxylated) octafluorobiphenyl, 1-2 parts of dibutyltin dilaurate, and 0.2-1 parts of polydimethyl amino thiazole. The present invention also provides a preparation method for the biodegradable waterproof polycarbonate composite material.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a biodegradable waterproof polycarbonate composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a thermoplastic with excellent comprehensive properties. It has good mechanical properties, heat resistance and dimensional stability, and has good heat resistance and cold resistance. It is widely used in electronics, electrical, chemical, machinery, automobiles , construction and other industries. [0003] Polycarbonate has a good improvement in rigidity and heat resistance and has good strength. It is mainly used in the manufacture of shells of some precision instruments to replace metal products to meet the needs of certain rigidity, dimensional stability, and light weight. and impact resistant parts and housings. However, compared with metal materials, the existing modified PC materials are almost the same in terms of mechanica...
