摘要
研究煅烧陶土在三元乙丙橡胶(EPDM)电线电缆胶料中的应用,考察了陶土粒径、陶土用量、硅烷偶联剂用量、填料种类对胶料硫化特性、力学性能、导电和导热性能的影响。结果表明:填充100份粒径为8. 5μm的陶土时胶料的综合性能较好;在陶土填充胶料中配合使用少量硅烷偶联剂A-172(用量为陶土的0. 25%),可以在保证EPDM硫化胶良好的导电和导热性能的前提下进一步提高力学性能。陶土可以取代超细碳酸钙用于EPDM电线电缆料中,具有明显的性能优势。
The application of calcined clay in EPDM wire and cable shield was studied. The effects of particle size and amount of calcined clay,the amount of silane coupling agent,and the filler type on the curing characteristics,mechanical properties,electrical conductivity and thermal conductivity of the compound were investigated. The results showed that,the compound filled with 100 phr calcined clay with particle size of 8. 5 μm showed better comprehensive performance. The addition of a small amount of silane coupling agent A-172 could further improve the mechanical properties and ensure good electrical conductivity and thermal conductivity of the vulcanizates. The optimum amount of silane coupling agent A-172 was 0. 25%of the calcined clay. Due to the performance advantages of the calcined clay,it could be used to replace the superfine calcium carbonate in EPDM wire and cable shield.
