Problems solved by technology

In the past, the most widely used biomedical materials were metal and organic materials, but they had many disadvantages. For example, after metal materials are implanted into the human body, they are prone to corrosion, produce metal ions that are toxic to the human body, and metal wear debris will cause surrounding Changes in biological tissues and other issues; while most organic materials have low strength, it is difficult to meet the requirements of mechanical properties and durability

Abstract

The invention provides a composite bioceramic material and a preparation method thereof. The preparation method comprises the steps as follows: S1, porous hydroxyapatite, two-phase calcium phosphate ceramic, octacalcium phosphate, calcium pyrophosphate, calcium nitrate, ramie seed gum, carbon spheres, nano titania, chitosan, nano zinc oxide, strontium carbonate and distilled water are mixed, and the mixture is ball-milled in a planetary ball mill; S2, polylactic acid, phenolic epoxy resin and 3,3'-diaminodipropylamine are added, and the mixture is stirred at the rotating speed of 100-200 r / min; S3, a polyoxyethylene-polyoxypropylene copolymer, polyoxyethylene-polyoxypropylene pentaerythrilol ether and polyethylene glycol are added, and the mixture is stirred and then placed in a vacuum drying oven to be vacuumized for defoaming treatment; S4, the obtained mixture is poured in a freeze casting device and a frozen green body is obtained; S5, the green body is placed in a sintering furnace to be sintered for 3-4 h after being freeze-dried, and the composite bioceramic material is obtained. The composite bioceramic material has very good biocompatibility and good mechanical performance.

Description

technical field [0001] The invention relates to the field of biomaterials, in particular to a composite bioceramic material and a preparation method thereof. Background technique [0002] With the development of material science, biomaterials have become an important part of today's biomedical engineering because of their special functions of repairing, replacing and regenerating body tissues. In the past, the most widely used biomedical materials were metal and organic materials, but they had many disadvantages. For example, after metal materials are implanted into the human body, they are prone to corrosion, produce metal ions that are toxic to the human body, and metal wear debris will cause surrounding Changes in biological tissues and other issues; while organic materials are mostly low in strength, and it is difficult to meet the requirements of mechanical properties and durability. Bioceramics generally refers to ceramic materials related to living organisms or bioch...
