Degradable polypropylene carbonate for injection machining

Abstract

The invention discloses a degradable polypropylene carbonate for injection machining. The degradable polypropylene carbonate for injection machining is composed of a polypropylene carbonate plastic, an ageing-proof agent, a heat stabilizer, a dispersant, a flexibilizer and a cross-linking agent, the anti-ageing agent is dihydroquinoline, the heat stabilizer is phosphite, the dispersant is barium stearate, the flexibilizer is chlorosulfonated polyethylene, and the cross-linking agent is methyltriethoxysilane. The degradable polypropylene carbonate for injection machining is composed of the polypropylene carbonate plastic, the ageing-proof agent, the heat stabilizer, the dispersant, the flexibilizer and the cross-linking agent, so the degradable polypropylene carbonate for injection machining has the characteristics of environmental protection, easy decomposition, long service life, high temperature resistance, good toughness and low cost.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to a decomposable polypropylene carbonate for injection molding processing. Background technique [0002] Polypropylene carbonate is also known as polymethylethylene carbonate, which is based on carbon dioxide and Propylene oxide It is a completely degradable and environmentally friendly plastic synthesized as a raw material, which can be used in fresh-keeping films for meat products (-80°C), degradable foam materials, plates, disposable tableware, disposable medical, food packaging materials, etc. With the rapid development of my country's food industry, the demand for disposable tableware and medical supplies is increasing. However, due to the low transition temperature of polypropylene carbonate, it is often used to prepare products used at low temperatures, so there are great limitations. . [0003] Polypropylene carbonate should be one of the most promising enviro...
