Modified polyethylene and preparation method thereof

The invention relates to the technical field of plastic products, in particular to modified polyethylene and a preparation method thereof. The modified polyethylene is prepared from the following components in parts by weight: 100 parts of polyethylene, 15 to 20 parts of collagen master batch particles and 0.1 to 0.2 part of dicumyl peroxide. According to the preparation method, collagen is prepared into the collagen master batch particles, the modified polyethylene is prepared from the collagen master batch particles, the polyethylene and other components, so that the compatibility of the collagen master batch particles and the polyethylene can be effectively improved, the toughness and the ultraviolet aging resistance of the polyethylene are more effectively improved, and the modified polyethylene is more suitable for being prepared into the polyethylene buoy. 本申请涉及塑料制品技术领域，具体涉及一种改性聚乙烯及其制备方法。一种改性聚乙烯，包括以下重量份的组分：聚乙烯100份、胶原蛋白母胶粒15-20份、过氧化二异丙苯0.1-0.2份。本申请采取将胶原蛋白制成胶原蛋白母胶粒和聚乙烯以及其他组分制备成改性聚乙烯，能够有效增加胶原蛋白母胶粒与聚乙烯的相容性，
