摘要:

目的分析含有不同类型酸性树脂单体的硅烷偶联剂及不同类型树脂粘接剂的相互组合对玻璃渗透氧化铝陶瓷树脂粘接耐久性的影响。方法使用3种硅烷偶联剂处理玻璃渗透氧化铝陶瓷的表面,使用2种双重固化树脂粘接剂与之粘接。测量试件在0和30 000次冷热循环后的粘接强度。结果冷热循环前,粘接剂A与未硅烷化处理陶瓷间的粘接强度显著低于其他硅烷化处理组,粘接剂A、B与偶联剂B处理的陶瓷间的粘接强度显著低于其与偶联剂A和C的粘接强度。冷热循环30 000次后,粘接剂A与未硅烷化处理陶瓷组的试件全部脱落;而其他硅烷化处理陶瓷组中,只有偶联剂A处理的陶瓷表面与粘接剂A和B间的粘接强度达到了5 MPa以上。结论使用10-甲基丙烯酰氧癸基磷酸酯作为硅烷水解剂的硅烷偶联剂处理的玻璃渗透氧化铝陶瓷能够与不同类型的树脂粘接剂获得较好的粘接耐久性。

Abstract:

Objective To analyze the effect of different silane coupling agents on the resin bond durability of glass-infiltrated alumina ceramic. Methods A glass-infiltrated alumina ceramic was silanized or not by three silane coupling agents. The treated ceramic surfaces were bonded with two resin cements. Their micro-bond strength were measured after 0, 30 000 thermal cycles. Results Before thermal cycling, resin cement A had lowest bond strength to ceramic, and ceramic treated by silane coupling agent A with two cements had lower bond strength than those treated by silane coupling agent B and C. After thermal cycling, cement A had no bond strength with no treated ceramic, only ceramic treated by silane coupling agent A with two cements had more than 5 MPa bond strength. Conclusion The glass-infiltrated alumina cermaic treated by the silane coupling agent activated by 10-methacryloyloxydecyl- dihydrogen phosphate could obtain better bond durability with different type of resin cements.
