将骨胶(BG)经戊二醛交联改性后,插层到蒙脱土(MMT)中,得到了交联型骨胶/MMT插层复合物。对骨胶插层的影响因素及改性后骨胶的性能进行了研究、讨论,并对改性后骨胶的结构和性能进行了表征。结果表明,制备交联型骨胶/MMT复合物的最佳工艺为反应温度30℃、反应时间1h、pH-7,所得骨胶的韧性得到了改善,热稳定性也有所提高。
The modified bone glue was prepared by grafting copolymerization with glutaraldehyde as modifier, and then it was intercalated by montmorillonite. The influencing factors and performance of glutaraldehyde bone glue intercalated by montmorillonite was studied and discussed. The performance was characterized. The result showed that the optimum process conditions are reaction temperature 30 ℃, reaction time 1 h, and pH value 7; the toughness and thermal stability of the bone glue is improved under these conditions.
