Abstract
本文通过氢氧化铝和氯铂酸复配成功制备了无卤阻燃高温硫化硅橡胶。利用垂直燃烧实验研究了硅橡胶的阻燃性能；利用拉伸实验和硬度测试对所制备的阻燃硅橡胶进行了机械性能的研究。结果表明通过氢氧化铝和氯铂酸的协同作用，硅橡胶的阻燃性能明显提高，氯铂酸添加量10~50 ppm时硅橡胶的综合性能可满足用户使用需求。 The halogen-free flame retardant high temperature vulcanized silicone rubber was successfully prepared by aluminum hydroxide and chloroplatinic acid. The flame retardant properties of sili-cone rubber were studied by vertical combustion test. The mechanical properties of silicone rubber were studied by tensile test and hardness test. The results show that the flame retardant properties of silicone rubber were improved by the synergistic effect of aluminum hydroxide and chloroplatinic acid. When the chloroplatinic acid content is limited in 10 - 50 ppm, the compre-hensive properties of silicone rubber can meet the needs of users.
