Abstract

The invention relates to a radiation-resistant high-polymer material as well as a preparation method and application thereof, and solves the technical problems that after the high-polymer material is irradiated by high-energy rays or electron beams, the change in color is still more obvious, and the mechanical property is more greatly reduced. The radiation-resistant high-polymer material is prepared from the following components in parts by weight: 100 parts of base resin with a weight-average molecular weight of 100,000-200,000, 2-7 parts of inorganic nano-particles, 3-7 parts of a primary antioxidant, 4-5 parts of an auxiliary antioxidant, 3-7 parts of a light stabilizer and 3-6 parts of a ultraviolet absorbent. The invention simultaneously discloses the preparation method and the application of the radiation-resistant high-polymer material. The preparation method provided by the invention can be used in the field of the preparation of radiation-resistant high-polymer materials.

Description

technical field [0001] The invention relates to the field of biomedical polymer materials, in particular to a radiation-resistant polymer material and its preparation method and application. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose thermoplastic with low price, excellent performance and wide application. Due to the special bead structure of PVC, it has good physical, chemical and biological properties. PVC is currently the best material to meet performance requirements, value and safety standards in the field of medical devices. PVC products used in medicine include blood packs, blood vessels, catheters, dialysis equipment, mouthpieces and masks, oxygen delivery equipment, laboratory instruments and equipment, catheters and packaging equipment, etc. However, polyvinyl chloride has poor stability to light and heat. When it is above 100°C or exposed to sunlight for a long time, it will decompose to produce hydrogen chloride, and further aut...
