| 中文摘要: |
| 采用脂肪酸锌皂酯、脂肪酸锌皂和混合酸锌皂3种分散剂，将白炭黑在天然橡胶（NR）和NR/丁苯橡胶（SBR）工程机械轮胎胎面胶中的白炭黑用量增大至25份，考察3种分散剂对胶料性能的影响。结果表明：使用硅烷偶联剂的同时适当添加分散剂，可以增大工程机械轮胎胎面胶中白炭黑用量，提高胶料硫化速度、改善胶料的加工性能和物理性能、明显降低胶料的生热，延长轮胎使用寿命。 |
| 英文摘要: |
| The influence of dispersant on the properties of silica filled tread compound of OTR tire was investigated while the addition level of silica was increased up to 25 phr. Three dispersants were studied： mixtures of zinc soaps and fatty acid ester， zinc soaps of fatty acid， and zinc soaps of mixed acids. In the tread compound， the rubber was NR or the blend of NR and SBR. The results showed that， by using proper amount of dispersant with silane coupling agent， the addition level of silica in the tread compound could be increased， the curing rate increased， the processing properties and physical properties of the tread compound were improved， the heat build-up was significantly reduced and the service life of OTR tire was improved. |
