Processing method of engine rear suspension rubber for passenger car

The invention discloses a processing method of engine rear suspension rubber for a passenger car. The processing method comprises the steps as follows: step 1, weighing of raw materials: weighing andmixing the raw materials in parts by mass as follows: 80-120 parts of natural rubber, 20-40 parts of carbon black, 0.2-4 parts of insoluble sulfur, 1-7 parts of a sulfenamide or thiuram accelerator, 4-8 parts of an anti-aging agent, 2-6 parts of zinc oxide, 0.5-3 parts of stearic acid and 1-8 parts of paraffin oil; step 2, mixing preparation; step 3, forming and vulcanization; step 4, post-treatment and inspection. The rubber has the advantages of being good in working performance at the high temperature, excellent in heat resistance and capable of meeting actual use requirements. 本发明公开种乘用车用发动机后悬置橡胶的加工方法，包括以下步骤：步骤：原料称量；称取以下质量份数的原料进行混炼，天然橡胶80～120份、炭黑20～40份、不溶性硫磺0.2～4份、次磺酰胺类或秋兰姆类促进剂1～7份、防老剂4～8份、氧化锌2～6份、硬脂酸0.5～3份、石蜡油1～8份；步骤二、混炼制备：步骤三：成型与硫化；步骤四：后处理及检验。本发明具有高温情况下工作性能良好，耐热性能优异，满足实际使用要求的优点。
