Abstract

The invention discloses environmentally-friendly recycled polyethylene (PE) modified particles for an emulsion explosive package and a preparation method thereof. The recycled PE modified particle comprises the following components in parts by weight: 100 parts of waste toothpaste aluminum-plastic package recycled PE plastic, 0.2-0.5 part of photosensitizer, 0.03-0.05 part of caprylate compound and 1-3 parts of PE special toughening agent, wherein the photosensitizer comprises aromatic ketones and benzoin ethers. Through the recycled PE modified particles prepared by adding the photosensitizer, the caprylate compound and the PE special toughening agent, the performance defect of the traditional recycled plastic particles is overcome, the degradation performance of the recycled plastic is improved; and the recycled PE modified particle and the method disclosed by the invention facilitate the environmental protection and reduce the environmental pollution.

Description

technical field [0001] The invention relates to a recycled polyethylene material obtained by separating the aluminum and plastic packaging materials of waste toothpaste from aluminum and plastic, in particular to a recycled polyethylene modified particle which can be used as an environment-friendly emulsified explosive package and a preparation method thereof. Background technique [0002] With the advancement of chemical technology, plastic products are changing with each passing day, and more and more plastic products are applied to people's life and production fields. According to statistics, general-purpose plastics, which account for 70-80% of the total plastics produced in my country, will be converted into waste plastics within ten years, and nearly half of them will be converted into waste plastics within two years. my country's annual recyclable plastics are more than millions of tons, while the recycling rate of waste plastics in my country is low in the world, onl...
