摘要：In the past, the asbestos as a kind of reinforcing fibre is used in the sealing field because of its excellent properties. With the prohibition of asbestos, the sealing gasket made of non-asbestos fibre has become a research hotspot. Fibre and rubber, as important components of compressed rubber sheet gasket reinforced by non-asbestos fibre, play a key role in the performance. In this paper, sealing materials with different properties are prepared by adjusting the content of fibre and rubber respectively. The tensile strength, compression-resilience, creep relaxation and leak rate of the non-asbestos gaskets were tested and analysed. The results show that the sealing gasket has the best comprehensive performance when the content of aramid fibre is 10%, mineral fibre is 20%, natural rubber is 3% and nitrile butadiene rubber is 12% .
