Whisker reinforced composite PP material, preparation method thereof and plastic pipeline

Abstract

The invention discloses a whisker reinforced composite PP material, a preparation method thereof and a plastic pipeline. The whisker reinforced composite PP material is prepared from the following components in percentage by weight: 40 to 70 percent of PP resin base material, 5 to 25 percent of whisker silicon fiber, 5 to 30 percent of filler and 1 to 3 percent of plastic processing aid. Accordingto the whisker reinforced composite PP material, the preparation method thereof and the plastic pipeline, the strength, the chemical stability, the dispersity, the high temperature resistance and theinsulativity of the composite material can be improved, and the ignition loss and the oil absorption rate are reduced. By adopting the whisker reinforced modified material, glass fiber exposure can be eliminated, the appearance of the plastic pipeline can be improved, the flatness of the inner wall can be improved, the friction coefficient can be reduced, the thermal deformation temperature can be increased, the flame retardancy can be improved, the shrinkage deformation rate can be reduced, warping can be overcome, the processability can be improved, the product rigidity can be improved, thematerial specific gravity can be reduced, and the production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and relates to a plastic pipe material, in particular to a whisker-reinforced composite PP material, a preparation method thereof and a plastic pipe. Background technique [0002] New composite materials are composite materials with higher performance than traditional materials, which mainly refer to high-performance resin-based composite materials, metal-based composite materials, Ceramic matrix composites, glass matrix composites, carbon matrix composites and functional composites, etc. [0003] At present, human beings have entered the era of composite materials from the era of synthetic materials. Many scientists believe that the future metal matrix composites and non-metal matrix composites will largely focus on the research and application of discontinuous (including whiskers, particles and flake reinforcements) reinforcement materials. Therefore, the synthesis and application of wh...
