Abstract

According to the impact-resistant marine recycled polypropylene regenerated material and the preparation method thereof provided by the invention, an active cross-linking agent is adopted to connect aged and hydrolytic fractured molecular chains of marine recycled polypropylene, so that the molecular chains of waste polypropylene plastic are increased, the relative molecular weight is increased, and the comprehensive performance of the waste polypropylene plastic is improved; the problem that marine polypropylene cannot be recycled in an existing recycling technology is solved.

Description

[0001] Technical Field: The present invention relates to the field of modification technology processing of waste plastic recycling, in particular to an impact-resistant marine recycled polypropylene regenerated material and a preparation method thereof. Background technique: [0002] Marine plastic pollution has become a social and economic problem that the world needs to face together. Marine plastic pollution has become one of the most urgent environmental problems currently facing the world. All countries have formulated corresponding laws and regulations to solve them through scientific and technological innovation. The current crisis. In 2019, the "Osaka Declaration" adopted by the G20 summit included the "Blue Ocean Vision" plan, which aims to reduce the amount of waste plastics entering the ocean to zero by 2050. Sun Xiaodong reported that polyolefins are widely used in industries such as films, automobiles and home appliances due to their excellent electrical insulati...
