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 material, its preparation method and its application in the preparation of notebook casings. The composite material is made of the following raw materials in parts by weight: polycarbonate 40-65 parts; special-shaped glass fiber 30-50 parts; flame retardant 2-8 parts; anti-dripping agent 0.1-1 part; compatibilizer 2-8 parts; antioxidant 0.2-3 parts; lubricant 0.2- 3 parts; the special-shaped glass fiber is an alkali-free flat chopped glass fiber, the width of the special-shaped glass fiber is 30-40 μm, the thickness is 2-5 μm, and the length is 350-450 μm. The material of the invention has the characteristics of ultra-high modulus, low warpage, high flame retardancy, high impact performance, and good coating performance, and at the same time, the injection molding process is simple and the cost is low, and it is very suitable for preparing the notebook 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 application in the preparation of a notebook casing. 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 of electronic devices such as thinness, beauty, and ease of carrying. Since its inception, notebook computers have been rapidly developed with the advantages of small size and portability. At present, with the rapid development of mobile phones, tablet computers, etc., this convenient experience of notebook computers has encountered huge challenges. Therefore, how to make notebook computers have the characteristics of lighter and thinner, diversified appearance, three-dimensional structure, rich color selection, and excellent surface texture exper...
