| titleOfInvention | Method for preparing antibacterial porous composite bone restoration support frame by homogeneous phase self foaming method |
| abstract | The invention relates to the technical field of a functional material, in particular to a method for preparing an antibacterial porous composite bone restoration support frame by a homogeneous phase self foaming method. The method for preparing the antibacterial porous composite bone restoration support frame by the homogeneous phase self foaming method comprises the following steps that firstly, an nHA/DCPD/PU composite material is prepared; then, DCPD is enabled to release crystal water under the condition of the temperature higher than 75 DEG C so as to take a reaction with isocyanatoes in polyurethane prepolymers to produce CO2; under the nitrogen gas protection condition, 15g of glycerol modified castor oil is taken and is added into a three-necked bottle; 70 DEG C oil bath heating and mechanical stirring are performed for 0.5h; 6.5g of DCPD solid powder and 6.5g of nHA powder are added; 15g of IPDI is gradually dripped to obtain composite material prepolymers; then, 0.05mL of catalysts are added; the reaction is performed for about 0.5h; then, 0.5mL of chain expanding agents are added; the reaction is continuously performed for 2h; curing foaming is performed for 24h at 90 DEG C; washing and drying are performed to obtain the antibacterial porous composite bone restoration support frame. The manufactured support frame has the advantages that the pore distribution is uniform; the penetrating performance is good; the porosity is high; the physical performance is good; the proper hole structure and the high antibacterial performance are realized; great application potential is realized in the field of bone restoration. |
