| 中文摘要: |
| 采用白炭黑、硅烷偶联剂Si75和白色填料开发适用于特殊场所的实心轮胎白色胎面胶配方。与黑色胎面胶配方胶料相比，试验配方胶料的门尼粘度增大，Fmax增大，硫化速度略慢，硫化胶的硬度、100%定伸应力、300%定伸应力、拉伸强度和撕裂强度较高，60 ℃时的损耗因子和DIN磨耗指数较小。试验配方硫化胶片室外长时间停放后仍为灰白色，且无裂口现象，室内长时间停放后呈浅乳黄色或乳白色。试验轮胎停放2.5个月后再安装到叉车上，使用5个月后胎面仍保持白色，制动时无印痕，轮胎预计行驶时间超过17 000 h。 |
| 英文摘要: |
| The white tread compound of solid tire for special situation was developed by using silica，silane coupling agent Si75 and white filler.Compared with the black tread compound，the Mooney viscosity and Fmax of the test formula compound increased，and the curing speed was slightly slow.The hardness，the modulus at 100% and 300%，tensile strength and tear strength of the vulcanizate were higher，and the loss factor at 60 ℃ and DIN wear index were smaller.The vulcanization film of the test formula was still gray white and there was no crack after long outdoor parking，and it was light milk yellow or milky white after long-term indoor parking.The test tire was installed on the forklift after 2.5 months parking，it remained white after 5 months of usage，there was no mark during braking，and the expected driving time was over
17 000 h. |
