| 中文摘要: |
| 以不溶性硫黄的分散性为重点，对全钢子午线轮胎钢丝粘合胶[主体材料为天然橡胶（NR）]的混炼工艺温度进行研究。结果表明：钢丝粘合胶的混炼工艺温度适当，NR与不溶性硫黄均熔融且粘度接近，混炼剪切力较大，NR与不溶性硫黄大分子均处于“整链”运动状态，不溶性硫黄分散性较好；不溶性硫黄HD OT20钢丝粘合胶大配合试验混炼排胶温度控制为106 ℃时，胶料的表面粘合性能和物理性能较好，尤其是H抽出力较大。 |
| 英文摘要: |
| Focus on the dispersion of insoluble sulfur，the mixing temperature of the wire bonding compound for all-steel radial tire was studied，the compound used natural rubber（NR） as base material. The results showed that，when the mixing temperature was appropriate，the melt viscosity of insoluble sulfur was close to that of NR，the shearing force was high，the macromolecules of NR and insoluble sulfur were in the state of “whole chain” movement，and as a result，the dispersion of insoluble sulfur was good.When the discharging temperature of the workshop mixing process of the compound with insoluble sulfur HD OT20 was 106 ℃，the surface adhesion property and physical properties of the compound were good. Particularly， the H pull-out force of the compound was quite high. |
