Formulation Optimization of Rubber Sleeve Compound for V-belt Vulcanization
LIU Shiduo;Hebei Xinji Jinhao Rubber Co.,Ltd;
In this study,the formulation of rubber sleeve compound for V-belt vulcanization was optimized. Chlorinated butyl rubber(CIIR)1066 was used to replace CIIR1068 as the main material since the cost of CIIR1066 was lower and its supply was abundant. The optimized formulation was as follows:CIIR1066 100,carbon black N330/N774 60,silica 10,silicon powder B66 15,inorganic reinforcing agent JC-069 10,tear-resistant resin HR-801 5,coumarone resin 5,wear-resistant agent JTH-315 3,high temperature microcrystalline wax 2,antioxidant RD 1. 5,antioxidant BLE 1. 5,benzoic acid 2,coupling agent Si69 1. 5,anti-reversion agent TDB680 1. 5,sulfur 0. 2,and accelerator 3. With the modified compound and a lining of thin canvas,the service life of the rubber sleeve was significantly extended.
