摘要
研究了室温硫化有机硅密封剂的耐热性能。通过对有机硅密封剂耐热老化后拉伸性能的测试,研究了硅橡胶生胶结构、填料、抗氧化剂(耐热增效剂)、硫化体系对有机硅密封剂的耐热性能的影响,确定了有机硅密封剂的配方,其耐热温度达350℃。
The heat-resistant property of a room temperature-curable silicone sealant was studied in this paper.The tensile strength and elongation after hot air aging for 50~100h at 350℃ or 200h at 300℃ was determined.The relationship between the heat-resistant property of silicone sealant and the structure of polydiorganosiloxane,fillings,oxidation-resistant,curing ingredient was discussed.The result showed the prepared organic-silicone sealant could withstand 350℃.
