Abstract

The present invention relates to composite material, and is especially composite polypropylene material containing potassium titanate whisker and glass fiber. The composite material consists of (in weight portions) polypropylene400-600, potassium titanate whisker 1-400, glass fiber 150-400, inorganic stuffing 0-100, plasticizer 50-200 and other assistant 30-240. Owing to the special performance and modifying effect of potassium titanate whisker on polypropylene, glass fiber is made to combine with polypropylene stably and strongly, and this improves the performance of the composite material, including raised strength, impact resistance, heat resistance, heat insulating performance and gas permeating resistance and thus wider application range.

Description

technical field [0001] The invention relates to a composite material, in particular to a polypropylene composite material containing potassium titanate whiskers and glass fibers. Background technique [0002] Polypropylene is a thermoplastic material with non-toxicity, low water absorption and good chemical stability. At the same time, due to its high mechanical strength, it is suitable for processing into products of various shapes, and its low price, so , The application prospect of polypropylene in all walks of life is very broad. However, due to the existence of defects such as high crystallization tendency of polypropylene, poor resistance to low temperature brittleness, large dimensional shrinkage, and insufficient rigidity, at present, polypropylene used in various industries has been improved through filling, strengthening, blending, and compounding. Non-toxic polypropylene, Chinese patent application number 01108594.0 discloses a microfiber / ultrafine powder / polypro...
