Abstract

The invention relates to a polypropylene composite material, which comprises the following components in part by weight: 65 to 70 parts of polypropylene, 25 to 27 parts of glass fibers, 2 to 4 parts of compatilizer, 2 to 4 parts of flexibilizer, 0.2 to 0.4 part of coupling agent, 0.2 to 0.4 part of antioxidant, 0.2 to 0.5 part of lubricant and 0.2 to 0.4 part of nucleator. The polypropylene composite material is high in mechanical strength and creep resistance.

Description

【Technical field】 [0001] The invention relates to a polymer material, in particular to a polypropylene composite material. 【Background technique】 [0002] Polypropylene has the advantages of low density, easy processing, good stress bending resistance, good chemical resistance, non-toxic, etc., so it can be applied to the food field. However, traditional polypropylene has low mechanical strength and poor creep resistance, so it is not suitable for manufacturing water purifiers and other equipment. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a polypropylene composite material with high mechanical strength and good creep resistance. [0004] A polypropylene composite material, in parts by weight, comprising 65-70 parts of polypropylene, 25-27 parts of glass fiber, 2-4 parts of compatibilizer, 2-4 parts of toughening agent, 0.2- 0.4 part of coupling agent, 0.2-0.4 part of antioxidant, 0.2-0.5 part of lubricant and 0.2-0.4 part ...
