The invention discloses a composite degradable copolymer-calcium silicate bone repair material preparation method. A composite degradable copolymer-calcium silicate bone repair material is prepared by composition of degradable lactic acid-basic amino acid copolymer and calcium silicate. The preparation method includes the steps of mixing lactic acid with the basic amino acid, dewatering, performing pre-polymerization reaction at the presence of a catalyst and at low temperature, heating to complete a polymerization reaction to obtain a lactic acid-basic amino acid copolymer, and subjecting the lactic acid-basic amino acid copolymer to composite reaction with the calcium silicate to obtain the composite degradable copolymer-calcium silicate bone repair material. The composite degradable copolymer-calcium silicate bone repair material manufactured by the method can be manufactured into different bone repair products for clinical requirements by means of extrusion molding or injection molding ...

The invention discloses a degradable copolymer-calcium silicate composite bone repair material and a preparation method thereof. The bone repair material is prepared from a degradable lactic acid-alkaline amino acid copolymer and calcium silicate in a compounding manner, wherein the calcium silicate is 10%-50% of total mass of the bone repair material; the lactic acid-basic amino acid copolymer is prepared from L-lactic acid and at least one alpha-alkaline amino acid in a polymerization manner, wherein the alkaline amino acid is 5%-30% of total molar weight of the copolymer. The method comprises the following steps: mixing and dewatering the L-lactic acid and the alkaline amino acid, carrying out polymerization reaction at a relatively low temperature in presence of a catalyst, heating and finishing polymerization reaction, so as to obtain the lactic acid-alkaline amino acid copolymer; and compounding and reacting with calcium silicate, so as to obtain a target product. Bone repair products ...

The invention discloses a bone repair product with degradable copolymer-calcium silicate composite bone repair materials serving as raw materials. The composite bone repair materials are composed of degradable lactic acid-basic amino acid copolymers and calcium silicate. The calcium silicate occupies 25% to 40% of the total mass of the bone repair materials, and the lactic acid-basic amino acid copolymers is formed by polymerization of L-lactic acid and at least one alpha-basic amino acid, wherein the basic amino acid is 5% to 30% of the total molar weight of the copolymers. The bone repair product is degradable in bodies and capable of providing calcium and silicon ions for bone tissues, high in biological activity; apparent advantages are provided in aspects of promotion of collagen synthesis, cell proliferation and differentiation and the like; degradation products has no obvious effect on surroundings.
