Abstract

The invention discloses a modified polypropylene resin and a preparation method thereof, wherein the modified polypropylene resin comprises the following components in parts by weight: 50-60 parts ofpolypropylene, 10-15 parts of low-density polyethylene, 10-15 parts of high-density polyethylene, 20-25 parts of a toughening agent and 0.2-1 part of an auxiliary agent, wherein the auxiliary agent comprises an antioxidant and an anti-aging agent. According to the modified polypropylene resin and the preparation method thereof disclosed by the invention, market requirements can be well met, and the modified polypropylene resin has good toughness and oxygen aging resistance, can meet VOC requirements, is low in cost and simple to process, and can further replace imported materials.

Description

Technical field [0001] The invention relates to the field of new materials, in particular to a modified polypropylene resin and a preparation method thereof. Background technique [0002] Polypropylene is a widely used thermoplastic with low price and good overall performance. The addition of additives allows it to greatly improve its toughness, oxidation resistance and cold resistance, and effectively reduces the material’s Because of its fluidity, it can be used on the surface of the car cable, which significantly improves the gloss and environmental protection of the cable surface. [0003] However, polypropylene resin is mostly imported, and its cost is relatively high. As the requirements increase, its performance can no longer meet the market requirements. Summary of the invention [0004] The invention discloses a modified polypropylene resin and a preparation method thereof, which improves the toughness, aging resistance and cold resistance of the polypropylene resin, reduc...
