摘要:
考察了白炭黑、羟基硅油对硅橡胶复合材料摩擦性能的影响，研究了硅橡胶复合材料在干、湿光滑玻璃表面摩擦系数的影响因素及摩擦机理。结果表明，硅橡胶复合材料在光滑玻璃表面的干摩擦系数（fD）与损耗因子（tan δ）/邵尔A硬度（H）、tan δ/剪切储能模量（G′）均呈线性正相关，随白炭黑用量的增加， fD降低。当增塑剂用量小于7.5份、H不小于34时，硅橡胶复合材料的fD与tan δ/H、tan δ/G′均呈线性正相关。当增塑剂用量不小于7.5份、H小于34时，应变为42%时的tan δ与fD呈线性正相关。在水润滑的光滑玻璃表面上，硅橡胶复合材料的湿摩擦系数与tan δ正相关。
Abstract:
Effects of silica and hydroxyl silicone oil on the friction properties of silicone rubber composites were investigated, and the influencing factors and friction mechanism of silicone rubber composites on dry and wet smooth glass surfaces were studied. The results showed that the dry friction coefficient (fD) of silicone rubber composites on smooth glass surfaces was linearly positive with loss factor (tan δ)/Shore A hardness (H), tan δ/shear storage modulus (G′), fD decreased with increasing silica amount. When the amount of plasticizer was less than 7.5 phr and H was no less than 34, fD of the silicone rubber composite had a linear positive correlation with tan δ/H and tan δ/G′. When the amount of plasticizer was no less than 7.5 phr and H was less than 34, the tan δ at a maximum strain of 42% had a linear positive correlation with fD. On a water-lubricated smooth glass surface, the wet friction coefficient of silicone rubber composites was positively correlated with tan δ.
