Abstract

The invention discloses a poly-butylene succinate/natural rubber composite degradable toughness material. The material comprises the raw materials in percentage by weight: 70-90 percent of poly-butylene succinate and 10-30 percent of natural rubbers, wherein the poly-butylene succinate is an aggregate material, and the natural rubber is a dispersed phase. The composite degradable toughness material is high in toughness; the preparation method is simple and feasible, and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a polybutylene succinate / natural rubber composite degradable tough material. Background technique [0002] With the application of plastic products more and more widely, white pollution is becoming more and more serious. Degradable plastics have recently been rapidly developed because they can replace petroleum-based polymer materials and products are naturally degradable in natural environments. [0003] At present, there are many reports on degradable and degradable plastics. Generally, natural degradable substances such as starch can be added to degradable plastics, but many products also contain polyolefin components that are difficult to degrade. Among them, the invention patent CN1037107C describes a biodegradable The manufacturing method of plastic, which is made by blending polyolefin, modified starch, plasticizer and other additives, wherein the mass fraction of polyo...
