Bone regeneration promoting composite material and preparation method thereof

The invention provides a preparation method of a bone regeneration promoting composite material. The preparation method of the bone regeneration promoting composite material comprises the following steps of: 1) taking alkane diol and polybasic acid as raw materials, and preparing a hydrophilic and hydrophobic fragment polymer through condensation polymerization; 2) performing double-bonding on thehydrophilic and hydrophobic fragment polymer obtained in the step 1) to obtain a double-bonded hydrophilic and hydrophobic fragment polymer; and 3) taking the double-bonded hydrophilic and hydrophobic fragment polymer obtained in the step 2), an inorganic material and a processing aid as raw materials, and performing polymerization reaction to obtain the bone regeneration promoting composite material. According to the bone regeneration promoting composite material and the preparation method thereof, the preparation process is simple, the cost is low, the bone regeneration promoting compositematerial can be randomly p
