Abstract

The invention discloses impact-resistant toughening PP plastic. The impact-resistant toughening PP plastic is prepared from, by weight, 60-70 parts of PP, 30-40 parts of thermoplastic elastomer, 0.3-0.8 part of antioxidant, 0.7-1 part of lubricant and 2-4 parts of layered graphene oxide. The invention further discloses a preparation method of the impact-resistant toughening PP plastic. The modified impact-resistant toughening PP plastic has high impact-resistant strength and has good anti-aging performance.

Description

technical field [0001] The invention relates to the technical field of tree PP plastic and its preparation, in particular to an impact-resistant and toughened PP plastic and a preparation method thereof. Background technique [0002] Polypropylene (PP) is polymerized from propylene monomer and is a non-polar crystalline plastic with a 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, high temperature corrosion resistance and other excellent properties, but also has good transparency and electrical insulation. Due to its many sources of raw materials and low cost, PP is widely used in industry, agriculture, medical care, daily necessities and packaging, etc. in the field. [0003] However, PP plastics have many deficiencies: mainly low-temperature brittleness, poor dimensional stability, poor aging resist...
