摘要
研究硫化剂DCP用量对四丙氟橡胶耐热空气老化性能、耐盐酸和硫化氢腐蚀性能的影响。结果表明:四丙氟橡胶硫化胶经热空气老化后的物理性能有所提高,经盐酸和硫化氢腐蚀后物理性能下降;盐酸、硫化氢、热空气3种介质对四丙氟橡胶硫化胶的腐蚀能力依次下降。当硫化剂DCP用量为3份时,四丙氟橡胶硫化胶在3种介质中的耐腐蚀老化性能最佳。
The effect of addition level of curing agent DCP on the hot air aging property, hydro- chloric acid and hydrogen sulfide corrosion resistance of tetrafluoroethylene-propylene rubber was in- vestigated. The results showed that,the physical property of tetrafluoroethylene-propylene rubber in- creased after hot air aging, but decreased after hydrochloric acid and hydrogen sulfide corrosion. The corrosivity of hydrochloric acid,hydrogen sulfide and hot air descended successively. The better corro- sion resistance of tetrafluoroethylene-propylene rubber in three mediums was attained when the addi- tion level of curing agent DCP was 3 phr.
