Abstract

The invention discloses a degradable environment-friendly polymer composite, and relates to the technical field of polymer composites. The degradable environment-friendly polymer composite is preparedfrom the raw material components in parts by weight: 10-60 parts of polybutylene succinate, 20-30 parts of polyhydroxyalkanoate, 1-5 parts of collagen, 2-8 parts of aliphatic polyester, 25-65 parts of chitin, 15-25 parts of cellulose, 22-45 parts of polyamino acid, 55-95 parts of polylactic acid, 2-55 parts of polycaprolactone, 9-15 parts of polyphosphazene, 3-10 parts of chitosan, 11-55 parts ofacetylchloride, 1-5 parts of a silane coupling agent, and 8-15 parts of n-octanol, wherein the polybutylene succinate, the polyhydroxyalkanoate, the collagen, the aliphatic polyester, the chitin, thecellulose, the polyamino acid, the polylactic acid, the polycaprolactone and the polyphosphazene are taken as main agents, and the chitosan, the acetylchloride, the silane coupling agent and the n-octanol are taken as auxiliary agents. According to the degradable environment-friendly polymer composite, through combination of materials such as the chitin, the cellulose, the polycaprolactone and the polybutylene succinate, the polymer composite completely meets the medical standard in the using process, the durability of the polymer composite is far higher than that of materials in the same industry, the strength and tenacity of the composite enable the service life to exceed the designed service life, after a medical device made of the composite is separated from the human body, the medical device can be degraded in the natural environment within 6-12 months, and thus environment pollution is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a degradable and environment-friendly polymer composite material and a production process. Background technique [0002] Polymer materials and other substances with different compositions, shapes, and properties are composited and bonded multi-phase solid materials, and have interfaces. The biggest advantage of polymer composite materials is to take advantage of the strengths of various materials, such as high strength, light weight, temperature resistance, corrosion resistance, heat insulation, insulation and other properties. According to the application purpose, select polymer materials and other materials with special properties. into a composite material that meets the needs. [0003] The contemporary medical industry uses a large number of medical auxiliary devices when treating patients, such as artificial blood vessels, artificial joints and teeth, et...
