Abstract

The invention discloses a glass fiber reinforced polypropylene composite material with high thermo-oxidative aging resistance and a preparation method of the glass fiber reinforced polypropylene composite material. The glass fiber reinforced polypropylene composite material is prepared from components in parts by weight as follows: 70-80 parts of polypropylene homopolymers, 20-30 parts of glass fiber, 4-6 parts of a compatilizer, 0.5-0.8 parts of zinc oxide and 0.6-1 part of an antioxidant, wherein the compatilizer is one of CMG9801, BONDYRAM 1001 or KT-1. By addition of the compatilizer, zincoxide and the antioxidant to the glass fiber reinforced polypropylene composite material and adoption of a reasonable ratio, weather resistance of the material can be substantially improved, and prepared glass fiber reinforced polypropylene has higher performance retention rate after thermo-oxidative aging and is suitable for certain places with relatively strict requirements for the thermo-oxidative aging.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high heat-resistant oxygen aging glass fiber reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) material is one of the most commonly used general-purpose plastics. It has excellent characteristics such as light specific gravity, easy molding, chemical resistance, and good electrical insulation. However, PP material has large shrinkage, low strength, and heat resistance. Shortcomings such as poor aging ability also limit the use of PP materials in some occasions. [0003] The introduction of glass fiber reinforcement into the PP material can greatly increase the strength of the PP material and improve the shrinkage rate of the PP material, so that the glass fiber reinforced polypropylene material has been widely used, but under some harsh external conditions Because glass fiber reinforced polypropyle...
