Abstract

The invention discloses a preparation method of a composite material for joint prosthesis. The method comprises the following steps: firstly, weighing various components in parts by weight and mixing evenly in an even mixer to obtain a main material; secondly, adding a coupling agent and a dispersing agent to the main material and evenly mixing in the even mixer to obtain a mixture; thirdly, adding the mixture to a twin-screw extruder, evenly mixing and performing melting extrusion; and fourthly, performing grain-sized dicing, sieving and packaging after cooling. The preparation method is relatively short in flow, simple to operate, low in cost, environment-friendly, and high in economic benefit; and the composite material for the joint prosthesis has excellent bioactivity, biocompatibility and osteoconduction and is superior to medical titanium and silicone rubber, and also is high in strength and good in mechanical properties.

Description

technical field [0001] The invention belongs to the field of polymer materials and relates to a preparation method of composite materials for artificial joints. technical background [0002] With its excellent properties, reliable performance, and convenient molding process, plastics have been widely used in the medical field, which makes the preparation of medical supplies with plastic materials very promising. First of all, plastics have good physical and mechanical properties and chemical stability, and are more suitable for use in the medical field; secondly, polymer materials are rich in sources and low in price, and are suitable for making disposable medical supplies, avoiding the high price of traditional materials. Disinfection and cross-infection problems caused by repeated use; and plastics have or are relatively easy to modify to obtain good tissue compatibility and blood compatibility products; plastics are easy to process, low in production cost, suitable for va...
