Abstract

The invention provides a flame-retardant wear-resistant polycarbonate material which is prepared from the following components in parts by weight: 100 parts of polycarbonate, 0.4-0.9 part of anti-ultraviolet agent, 0.5-1 part of antioxidant, 5-7 parts of compatilizer, 0.6-1.1 parts of stabilizer, 0.1-0.6 part of dispersing agent, 1-6 parts of plasticizer, 2-7 parts of toughener, 3-3.5 parts of organosilicon wax and 18-24 parts of modified composite wollastonite fiber. The invention also discloses a manufacturing method of the polycarbonate material. The polycarbonate material provided by the invention has high flame retardancy and wear resistance.

Description

technical field [0001] The invention relates to a polymer material, in particular to a flame-retardant and wear-resistant polycarbonate material and a manufacturing method thereof. Background technique [0002] Polycarbonate material is a tasteless, odorless, non-toxic and transparent amorphous thermoplastic material. It is a general term for a class of polymer compounds containing carbonate in the molecular chain, referred to as PC, which can be divided into aliphatic and There are two types of aromatic polycarbonate, but due to the constraints of product performance, processing performance and economic factors, only bisphenol A aromatic polycarbonate has been put into industrial scale production and application. Bisphenol A polycarbonate is currently the polycarbonate with the largest output and the widest application, and it is also one of the fastest-growing engineering plastics. Bisphenol A polycarbonate has excellent impact strength, creep resistance, heat and cold re...
