Embodiment 1

[0028] The invention provides a technical solution: a production process of PPC degradable plastics, comprising the following raw materials in parts by weight: 100 parts of polypropylene carbonate, 20 parts of poly-β-hydroxybutyrate, 12 parts of natural rubber, poly 10 parts of lactic acid colored silk, 5 parts of epoxy resin, 1 part of glycerin, 3 parts of coupling agent, 15 parts of starch phosphate and 18 parts of auxiliary agent.

[0029] As a preferred solution, further, the following steps are also included:

[0030] 1) Weighing polypropylene carbonate, poly-β-hydroxybutyrate and natural rubber in proportion to fully mix and stir through a high-speed mixer to ensure the complete degradability of plastic products, while reducing the brittleness of plastic products and avoiding cracking;

[0031] 2), continue to add polylactic acid colored yarn, epoxy resin, glycerin, coupling agent, starch phosphate and auxiliary agents in proportion, and stir for 5 minutes under the cond...

Abstract

The invention discloses a production process of PPC degradable plastic. The PPC degradable plastic is prepared from the following raw materials in parts by weight: 100 parts of polypropylene carbonate, 20-30 parts of poly-beta-hydroxybutyrate, 12-18 parts of natural rubber, 10-15 parts of polylactic acid color silk, 5-10 parts of epoxy resin, 1-5 parts of glycerol, 3-5 parts of a coupling agent, 15-20 parts of starch phosphate and 18-23 parts of an auxiliary agent. According to the production process of the PPC degradable plastic, the environment-friendly and pollution-free effect is guaranteed, and meanwhile, the complete degradation effect is achieved; the comprehensive performance of the plastic product is improved; and the production quality of plastic products is ensured.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a production process of PPC degradable plastic. Background technique [0002] PPC plastic, also known as polymethylethylene carbonate, is a completely degradable and environmentally friendly plastic synthesized from carbon dioxide and propylene oxide. Polypropylene carbonate is soluble in polar solvents, such as lower ketones. , ethyl acetate, dichloromethane and chlorinated hydrocarbons, insoluble in solvents such as alcohols, water and aliphatic hydrocarbons, it also forms a stable emulsion in water, PPC does not allow gases such as oxygen to diffuse through it, and the glass temperature (Tg) is at Between 25 and 45°C, the PPC adhesive is amorphous, and the glass temperature of PPC is slightly higher than that of polyethylene carbonate; [0003] Nowadays, more and more companies are beginning to pay attention to the production of PPC plastic products. However, in th...
