天然橡胶套扎器胶圈的抗湿滑性能及机理
Wet-skid resistance and its mechanism of new ligation bands based on natural rubber
摘要
Abstract
Considering the poor wet-skid resistance (WSR) and facile abscission of natural rubber (NR) when applied in ligation band, a new ligation rubber ring based on NR was prepared when used fumed silica as reinforcing agent and glycerol-gelatin as processing agent, which met with the application of ligation bands in mechanical property. Meanwhile, the property of WSR of the ligation rubber ring was characterized by stress, stress relaxation, surface roughness, micro-hardness and dynamic viscoelasticity. The results showed that the stretching stress of NR on 500% was 6.12 MPa, surface micro-roughness (Ra) was 9.754, and excellent micro-hardness and tanδ. Besides, the coefficient of maximum static friction on wet surface was 2.6. All above results indicated that a good wet-skid resistance was obtained in the new ligation rubber ring.关键词
