Problems solved by technology

However, the thickness and width of the flat glass fiber used in this patent document do not have a reserved length for the glass fiber, and the comprehensive balance between the strength and warpage performance of the composite material has not been realized to the greatest extent, and its mechanical properties are yet to be determined. At the same time, the heat resistance and coating performance of the composite material are not good enough

Abstract

The invention discloses a glass fiber reinforced polycarbonate composite, a preparation method thereof and application of the glass fiber reinforced polycarbonate composite in preparation of a laptop shell. With 100 weight parts in total, the composite is prepared from, by weight, 40-65 parts of polycarbonate, 30-50 parts of special-shaped glass fiber, 2-8 parts of fire retardant, 0.1-1 part of anti-drip agent, 2-8 parts of compatilizer, 0.2-3 parts of antioxidant and 0.2-3 parts of lubricant. Non-alkali flat short-cut glass fiber serves as the special-shaped glass fiber, and the special-shaped glass fiber has the width of 30-40 microns, the thickness of 2-5 microns and the length of 350-450 microns. The composite has the advantages of being ultrahigh in modulus, less in warping, high in fire retardant performance, high in impact property, good in coating performance and the like, and meanwhile the composite is easy to inject, low in cost and quite suitable for preparing the laptop shell.

Description

technical field [0001] The invention relates to the technical field of polycarbonate composite materials, in particular to a glass fiber-reinforced polycarbonate composite material, a preparation method thereof, and an application in preparing notebook casings. Background technique [0002] With the rapid development of China's economy and the popularization of the Internet, people have higher and higher requirements for the use experience of electronic devices such as thinner and lighter, more beautiful, and more convenient to carry. Notebook computer has just obtained rapid development with advantages such as volume is little, just to carry since its advent. At present, with the rapid development of mobile phones, tablet computers, etc., this convenient experience of notebook computers has encountered great challenges. Therefore, how to make the notebook computer more light and thin, the diversification of the three-dimensional structure of the appearance, rich color opti...
