Abstract

The invention discloses modifying agent used for PE waste plastic recycle. The modifying agent comprises polyethylene-maleic anhydride, epoxy resin, terpene resin, urea resin, epoxidized soybean oil,triethanolamine, silane coupling agent and lanthanide nitrate. The modifying agent is used for reprocessing of PE waste plastic, can effectively improves overall quality of the PE plastic, promotes the PE plastic to recover to process and use performances of the original plastic, promotes sound development of a reprocessing industry of the PE waste plastic, and has great population and use values.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a modifier for recycling PE waste plastics. Background technique [0002] PE is a kind of plastic that is used in a large amount in production and processing. Most of its products will be discarded into the natural environment after being used and discarded, causing serious pollution. In order to improve this problem, people think of recycling such waste materials. The method of its reuse is to reheat and plasticize it, make it into a viscous flow state, and then pelletize it for utilization. However, when PE waste plastics are processed at high temperature, the macromolecular chains will be depolymerized, and at the same time, the original modifier components will be lost, which will destroy the processing characteristics of PE plastics, thus affecting the overall quality of the products. This problem needs to be improved urgently. Contents of the inven...
