摘　　要：目的:研究硼酸铝晶须的添加量对硅橡胶类软衬材料机械性能的影响。方法:硼酸铝晶须经2%的硅烷偶联剂进行表面处理后,按照2%、3%、4%、5%的质量比添加到硅橡胶软衬材料中,未添加晶须的软衬材料作为对照组,按国家相关标准检测复合材料的邵氏硬度、拉伸强度及拉伸伸长率的变化并从每组中随机选出一个试件进行扫描电镜,观察晶须在复合材料中的分散情况。结果:随着硼酸铝晶须添加量的增加,邵氏硬度呈上升趋势,拉伸强度、拉伸伸长率呈先上升后下降的趋势,综合来看硼酸铝晶须的最佳添加量为4%。结论:硼酸铝晶须的添加量对硅橡胶软衬的机械性能有一定影响,且针对本实验硼酸铝晶须的含量,当添加量为4%时复合材料的综合机械性能较好。Objective：To study the effects of aluminum borate whiskers on the mechanical properties of silicone rubber soft lining material.Methods：Aluminum borate whisker surface treated with 2.0% silane coupling agent were added into silicone rubber soft lining composite according to the following mass fraction：2%、3%、4%、5%.The group without any whiskers was prepared.The tensile stength,the elongation at break,and the Shore hardness of the composite according to national standards were measured.A specimens of each group was randomly selected to observe the dispersion conditions of whisker in the composite scanning electron microscope.Results：With the increase of aluminum borate whisker,Shore hardness increased,tensile strength and tensile elongation showed a downward trend after the first rise.The whole optimal dosage of aluminum borate whiskers was 4%.Conclusion：The amount of aluminum borate whiskers have some influence on the mechanical properties of silicone rubber soft lining.According to the content of aluminum borate in this experiment,when the dosage of aluminum borate whisker was 4%,the composite material could achieve better mechanical properties.
