Abstract

The invention discloses a high-intensity porous bone repair material and a method for preparing the same. The method comprises the following: (1) a step of preparing a porous body, which is to use beta-tricalcium phosphate, bio-glass and a stable tetragonal zirconia power as a solid phase, add deionized water into the solid phase, add ammonium polyacrylate serving a dispersant, process the mixture by ball milling to prepare pulp, soak polyurethane foam completely into the pulp, take out the soaked foam, extrude excessive pulp out of the product so as to evenly coat the pulp on the pore walls of the porous body, dry the obtained product, place the dried product in a program control furnace or an electric resistance furnace, film the obtained product at a rising temperature and sinter the filmed product to form the porous body; (2) a step of soaking the obtained porous body in a water solution of NaOH, washing the product with deionized water in the atmosphere of ultra waves and drying the resulting product to obtain the high-intensity porous bone repair material. The high-intensity porous bone repair material of the invention has a high intensity and a high compressive strength, can be widely applied to repair skulls, frontal bones and the like and can also be used to reconstruct scaffolds of cell carriers in tissue engineering and repairing organs.

Description

technical field

[0001] The invention relates to a bone repair material and a preparation method thereof, in particular to a high-strength porous bone repair material and a preparation method thereof. Background technique

[0002] Bone repair materials, especially bone defect repair materials for large load-bearing parts, require materials with good mechanical properties. Traditional bioceramic bone repair materials mainly include tricalcium phosphate, hydroxyapatite and other glass ceramics. Tricalcium phosphate has good Hydroxyapatite has good osteoinductive ability, but it has inherent brittleness, which has restricted the application of this type of bone repair material. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a high-strength porous bone repair material.

[0004] The second object of the present invention is to provide a method for preparing a high-strength porous bone repair m...
