一种传动带材料及其制备方法
摘要：
本发明公开了一种传动带材料，配方组成为：天然橡胶10-25份、丁苯橡胶25-40份、丁腈橡胶60-75份、硫磺1-4份、增塑剂5-8份、粘合剂2-5份、氧化锌7-11份、防老剂RD 2-4份、防老剂NBC 1.5-3份、防老剂DNP 0.5-2份、炭黑15-18份、白炭黑5-6份、N-环已基-2-苯并噻唑次磺酰胺1-3份、2、2'-二硫代二苯并噻唑1-2份、硬脂酸3-5份、古马隆树脂10-11份、松焦油3.5-5份,上述为质量份。制备方法为：（1）将天然橡胶、丁苯橡胶、丁腈橡胶投入密炼机中，加热至110-120℃，（2）加入一半的炭黑升温至145-155℃混炼4-6分钟，依次加入氧化锌、白炭黑、古马隆树脂、促进剂、防老剂进行混炼。（3）往开炼机中加入剩余的炭黑、增塑剂、硫磺、松焦油继续混炼6-9分钟得到母胶，（4）将母胶置入硫化模具中进行硫化处理。
摘要（英）：

The invention discloses a transmission belt material. A formula of the material comprises the following components in parts by mass: 10 to 25 parts of natural rubber, 25 to 40 parts of styrene butadiene rubber, 60 to 75 parts of nitrile rubber, 1 to 4 parts of sulfur, 5 to 8 parts of plasticizer, 2 to 5 parts of bonding agent, 7 to 11 parts of zinc oxide, 2 to 4 parts of anti-aging agent RD, 1.5 to 3 parts of anti-aging agent NBC, 0.5 to 2 parts of anti-aging agent DNP, 15 to 18 parts of carbon black, 5 to 6 parts of white carbon black, 1 to 3 parts of N-cyclohexyl-2-benzothiazolesulfenamide, 1 to 2 parts of 2,2'-dibenzothiazyl disulfide, 3 to 5 parts of stearic acid, 10 to 11 parts of coumatone resin, and 3.5 to 5 parts of pine tar. A preparation method comprises the following steps: (1), putting the natural rubber, the styrene butadiene rubber and the nitrile rubber into a banbury mixer, heating to the temperature of 110 to 120 DEG C; (2), adding half of the carbon black and rising the temperature to be 145 to 155 DEG C for milling for 4 to 6min, sequentially adding the zinc oxide, the white carbon black, the coumatone resin, an accelerator and the anti-aging agents for milling; (3), adding the rest carbon black, the plasticizer, the sulfur and the pine tar into a open mill for carrying out milling for 6 to 9min to obtain masterbatch; (4), putting the masterbatch into a vulcanizing mold for carrying out vulcanization treatment.
