Abstract

The invention relates to a wear-resistant transparent flame-retardant polycarbonate material and a preparation method thereof. The wear-resistant transparent flame-retardant polycarbonate material comprises the following raw materials in parts by weight: 90-95 parts of polycarbonate, 5-10 parts of transparent flame-retardant masterbatches, 0.5-1 part of ZnO / SiO2 nano composite and 0.1-1 part of anantioxidant. The prepared polycarbonate material has high flame retardancy, high light transmitting rate and good wear resistance, and the other original mechanical properties of the material can beimproved. The flame-retardant masterbatches serve as the raw material components, the consistency is good, and the quality of the product is uniform and stable; and a double-screw extruder serves as processing equipment, and the technological process is simple and continuous.

Description

technical field [0001] The invention relates to the technical field of polycarbonate modified materials, in particular to a wear-resistant transparent flame-retardant polycarbonate material and a preparation method thereof. Background technique [0002] Polycarbonate is a heat-shrinkable engineering plastic with excellent comprehensive properties. It has high light transmittance, high impact resistance, high toughness, high heat resistance, weather resistance and excellent electrical insulation. It is widely used in the automotive industry, Instrumentation, electronic appliances and other fields. Polycarbonate itself has a certain degree of flame retardancy, but it cannot meet the occasions that require a higher level of flame retardancy. At the same time, polycarbonate has poor wear resistance. [0003] In order to ensure flame retardancy, the traditional addition of halogen-containing flame retardants has good flame retardancy, less addition, and less impact on mechanical...
