用3-甲基丙烯酰氧基丙基三甲氧基硅烷（MAPM）和3-丙烯酰氧基丙基三甲氧基硅烷（APM）对氧化锆-二氧化硅进行硅烷化，测定了在水中煮沸0-108 h后，对由这些硅烷化填料和氨基甲酸酯二甲基丙烯酸酯制成的复合材料的径向拉伸强度和横向强度的影响。还测量了这些复合材料在长达108 h的时间内的吸水性。硅烷化与任何硅烷显着增加了拉伸和横向强度，并降低吸水性相对于可比的unsilanated控制。在三倍于最小均匀覆盖率的条件下，用MAPM从乙醇溶液中硅烷化得到最佳的总体结果，并且拉伸强度测试似乎最能预测硅烷处理的有效性。
The effect of the method of silanation of zirconia-silica by 3-methacryloxypropyltrimethoxysilane (MAPM) and 3-acryloxypropyltrimethoxysilane (APM) on the diametral tensile and transverse strength of composites made from these silanated fillers and a urethane dimethacrylate was determined after 0-108 h of boiling in water. The water sorption of these composites was also measured at times up to 108 h. Silanation with either silane significantly increased the tensile and transverse strengths and decreased water sorption relative to comparable unsilanated controls. Silanation with MAPM from ethanol solution at three times the minimum uniform coverage gave the best overall results, and the tensile strength tests appeared to be most predictive of effectiveness of the silane treatments.
