GLASS FIBER-REINFORCED POLYCARBONATE COMPOSITE MATERIAL AND PREPARATION METHOD AND USE THEREFOR

WIPO Patent Application WO/2021/036612

A1

A glass fiber-reinforced polycarbonate composite material, comprising the following components in parts by weight: component A: 70 parts - 90 parts of a polycarbonate; component B: 3 parts - 55 parts of a glass fiber; component C: 0.01 parts - 1 part of an interfacial binder; component D: 0.01 parts - 10 parts of an antioxidant; and component E: 0.01 parts - 10 parts of an auxiliary antioxidant. By means of adding a specific amount of an interfacial binder and an antioxidant of a specific formulation to the formula for the glass fiber-reinforced polycarbonate composite material, the composite material prepared maintains rigidity and toughness under high-temperature aging, and is able to maintain electrical performance at a high rate, thus being able to ensure stability of long-term performance and aesthetic quality for long periods in high-temperature environments, and ensure the best performance over the service life of the material. The material is suitable for vehicles, electronics, the communications industry, the construction industry, and other fields, particularly the 5G communications industry.
