Hydroxyl apatite/nylon nanometer artificial bone and preparing method thereof

Abstract

The invention provides a hydroxyapatite / nylon manometer artificial bone, including hydroxyapatite which accounts for 50-66% of the total weight of the artificial bone; nylon which accounts for 34-50% of the total weight of the artificial bone; the hydroxyapatite disperses in the nylon under the dispersed phase with the average length between 60-80nm; the molecular weight of the nylon is between 9000-13000; in addition, the artificial bone is free of organic solvent. The invention can achieve high filling amount, no use of organic solvent, high product purity and can reach the standard set for the medical material.

Description

Technical field

[0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a hydroxyapatite / nylon artificial bone and a preparation method thereof. Background technique

[0002] The main inorganic component of natural bone is nano-hydroxyapatite, which is about 60-67% of bone tissue, and the organic component is mainly collagen, which accounts for about 33-40%. Using synthetic nano-acicular hydroxyapatite and polymer composite to prepare nano-artificial bone composite material, not only has the good biocompatibility and bone guiding characteristics of hydroxyapatite, but also combines the good mechanical properties of polymer materials and Biodegradable, it is a promising artificial bone composite material.

[0003] Nylon (nylon 66) is a kind of polyamide, which is an engineering plastic with good comprehensive properties. It not only has good mechanical properties, but also has good biocompatibility and a certain degree of bio...
