Abstract

The invention discloses an in-situ composite fiber forming polymer material. The in-situ composite fiber forming polymer material comprises the following components in parts by weight: 70-90 parts of matrix, 5-25 parts of fiber forming phase, 1-9 parts of compatilizer and 0.1-0.5 part of accessory ingredient. According to the in-situ composite fiber forming polymer material disclosed by the invention, the compatibility of the fiber forming phase and the matrix phase is well improved; the interface tension between the two phase interfaces is reduced; the fiber forming phase is dispersed in the matrix more uniformly under the high-speed shearing action of the extrusion process, so that that the fiber dimension of the fiber forming phase fibers is more uniform, the fiber distribution is more uniform, the matrix material is reinforced better; and the in-situ composite fiber forming polymer material has better tensile property and mechanical property.

Description

technical field [0001] The invention relates to the field of material science, in particular to a polymer material and its preparation method and device. Background technique [0002] Usually nylon fiber reinforced polymer is directly added to the polymer fiber or fiber cloth in the polymer melt. In this method, it is difficult to disperse the nylon fibers uniformly in the obtained fiber reinforced polymer material. [0003] In recent years, there have been many studies on in-situ fiber-reinforced polymer materials, which are applied to plates, pipes, auto parts and other fields. However, the processing methods and processes are relatively complicated, or the extrusion die used has a long flow path, which causes the easily degradable fiber phase to degrade easily, and the fiber phase affects the performance of the product, and it is difficult to achieve continuous production. Contents of the invention [0004] The purpose of the present invention is to provide a composit...
