Problems solved by technology

Generally speaking, most glass fiber reinforced materials are mostly used in structural parts of products. They are structural engineering materials with high strength, high rigidity, and low shrinkage. When the glass fiber content reaches a certain range, even It can partially replace steel, but its toughness is much lower than that of polypropylene, and it is easy to break and cause danger under high-speed and high-load conditions.

Abstract

The invention provides a reinforced polypropylene composite material and a preparation method thereof. The reinforced polypropylene composite material comprises 54-64 parts of PP (propene polymer) resin, 4-6 parts of polypropylene grafting maleic anhydride, 29-32 parts of glass fiber chopped strand, 3-5 parts of a flexibilizer, 0.2-1 part of an antioxidant, 0.5-1 part of a lubricant, 0.2-0.5 part of a floating fiber resisting agent, and 0.1-0.2 part of di(3,4 dimethyl) dibenzaldehyde sosrbitol. The reinforced polypropylene composite material prepared by the method holds high rigidity of glass fiber materials and reduces floating glass fibers, the impact strength and flowing property of the material are improved, and the reinforced polypropylene composite material can substitute for the existing materials of roller washing machines, and meets the requirements of high capacity, high load, high rotation speed and ultrathin sheet of modern washing machines.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a reinforced polypropylene composite material and a preparation method thereof. [0002] Background technique [0003] Drum washing machines have long been a necessity in modern society, and the buckets of drum washing machines are mainly made of modified plastics such as glass fiber reinforced polypropylene and talcum powder filled polypropylene. The two characteristics of the speed are the shaft, so the modified plastic resin is required to have the characteristics of high strength, high toughness, easy molding, and smooth surface of the workpiece. [0004] Polypropylene (PP) is a crystalline thermoplastic resin with excellent comprehensive properties. It is non-toxic, odorless, and low density. Use; at the same time, it has good electrical properties and high-frequency insulation and is not affected by humidity, but it will become brittle, not wear-resistant, and easy to ag...
