Problems solved by technology

However, due to the weak interaction between the glass fiber and the polymer matrix, it is easy to fall off from the polymer matrix to form a cavity, which not only significantly lowers the fiber reinforcement effect and mechanical properties of the material, but also affects the overall quality of the injection molded part. The support effect is also very limited, and its products are easy to warp and deform

Abstract

The invention discloses a polypropylene glass fiber composite material. The polypropylene glass fiber composite material is formed by compounding the following components by mass percentage: 40%-42% of polypropylene master batch, 36%-38% of glass fiber, 10%-12% of polypropylene fiber, 2%-4% of a coupling agent and 6%-10% of maleic anhydride grafted polypropylene, wherein the polypropylene master batch comprises T30S and EPS30R, the mass ratio of the T30S to the EPS30R in the polypropylene master batch is 1:1, and the polypropylene glass fiber composite material is formed by co-extrusion of double screws. By the above way, the mechanical properties and heat resistance of the polypropylene glass fiber composite material can be improved, the modulus of the polypropylene glass fiber compositematerial is not lower than that of a wood template, the product does not deform or bend easily, and the production cost can be lowered.

Description

technical field [0001] The invention relates to the field of glass fiber composite materials, in particular to a polypropylene glass fiber composite material. Background technique [0002] However, with the development of science and technology society, polypropylene is widely used in all aspects of daily life. At present, due to the low strength and modulus of polypropylene, it can no longer meet the application in some engineering fields. Improving the tensile strength and modulus of polypropylene is an effective way to broaden the application of polypropylene, and it is also an important field of high-performance polypropylene. [0003] Glass fiber is a one-dimensional inorganic filler with high strength and modulus. When it is added to the polymer matrix, it can effectively bear stress and load as a skeleton, which can significantly improve the mechanical properties of the polymer matrix and Heat resistance. [0004] At present, there have been a large number of resear...
