Problems solved by technology

PP also has many shortcomings: low-temperature brittleness, poor dimensional stability, poor aging resistance, and large molding shrinkage, easy to burn, and because of its non-polar characteristics, it is not easy to effectively combine with other polar polymers and inorganic fillers. Compatibility, which limits the application and development of PP

Abstract

The invention discloses graphene compounded anti-impact PP (Polypropylene) plastic. The graphene compounded anti-impact PP plastic is prepared from the following components in parts by weight: 70-80 parts of PP, 0.2-0.6 part of an antioxidant, 0.5-2 parts of a lubricant, 0.5-3 parts of a coupling agent and 1-3 parts of graphene oxide. The invention further discloses a preparation method of the graphene compounded anti-impact PP plastic. By adopting the graphene compounded anti-impact PP plastic, the impact strength of the PP plastic is high and the graphene compounded anti-impact PP plastic has a good anti-ageing performance.

Description

technical field [0001] The invention relates to the technical field of plastic modification and preparation thereof, in particular to a graphene composite impact-resistant PP plastic and a preparation method thereof. Background technique [0002] Polypropylene (PP) is polymerized from propylene monomer and belongs to a non-polar crystalline plastic with a very low water absorption rate of about 0.03%-0.04% and a melting point of 165-170°C. PP is a thermoplastic general-purpose plastic with excellent comprehensive properties, with a small density of about 0.91g / cm 3 , high strength and high temperature corrosion resistance, as well as good transparency and electrical insulation, PP is widely used in many fields such as industry, agriculture, medical treatment, daily necessities and packaging. PP also has many shortcomings: low temperature brittleness, poor dimensional stability, poor aging resistance, and large molding shrinkage, easy to burn. Compatibility limits the appli...
