Abstract

The invention discloses a polypropylene carbonate modified composite material. The composite material is prepared by blending the following components in parts by weight: 60-75 parts of polypropylene carbonate, 15-30 parts of polypropylene, 5-10 parts of a compatilizer, 0.1-0.2 part of a primary antioxidant, 0.1-0.2 part of an auxiliary antioxidant, 0.15-0.3 part of an ultraviolet absorbent and 0.3-0.8 part of an auxiliary agent. The invention also discloses a preparation method of the polypropylene carbonate modified composite material. PPC subjected to PP modification has good thermal stability, so that the processing temperature range of PPC can be expanded, and the application of a PPC material in occasions requiring high performances can be met; thermal performance test results show that the glass-transition temperature and thermal decomposition temperature of a PPC / PP blending material are higher than that of PPC before modification; therefore, the composite material disclosed by the invention can be widely applied to the fields of automobile industry, daily necessities, furniture industry, packaging industry, biological medicines and the like.

Description

[0001] technical field [0002] The invention relates to a polypropylene carbonate modified composite material, and also relates to a preparation method of the composite material, which belongs to the technical field of polymer materials. Background technique [0003] A simple and effective way to modify materials is to blend several polymers. PPC has a low glass transition temperature, poor thermal stability, and poor mechanical properties, which greatly limit the application and processing range of PPC (polypropylene carbonate, hereinafter referred to as PPC). Based on the degradable properties of PPC and meeting the requirements of industrial use, PPC can be blended with other high-performance polymers. Considering the processing temperature of PPC, it can complement the advantages of other polymers. [0004] PP (that is, polypropylene, hereinafter referred to as PP) has good comprehensive performance, rich sources of raw materials, simple production process, and low pri...
