探讨翻新轮胎预硫化胎面与胎体间粘合缓冲胶的性能。焦烧性能、塑性、流动性、硬度、定伸应力、老化性能、粘合性能是粘合缓冲胶重要的性能指标。主体材料可采用天然橡胶及其与顺丁橡胶的并用胶,低压低温硫化时要加入超促进剂,防护体系多用防老剂4020/RD和防老剂1010/亚磷酸盐类防老剂并用,抗硫化返原剂和粘合剂的品种和用量要适当,增塑剂多用松焦油、四线油、古马隆树脂和酚醛树脂。胶料一段混炼在密炼机中进行,二段混炼在开炼机上进行,开炼机辊温不宜超过50℃。
To investigate the performance of retreaded tire pre-vulcanized and carcass adhesive cushioning. Scorch performance, plasticity, fluidity, hardness, set stress, aging properties, adhesion performance is an important adhesive bonding adhesive performance indicators. The main material can be natural rubber and its adhesive with the use of butadiene rubber, low pressure vulcanization to join the super accelerator, multi-purpose protection system antioxidant 4020 / RD and antioxidant 1010 / phosphite antioxidant, anti-sulfide back The original agent and binder types and dosage should be appropriate, more plasticizer pine tar, four-wire oil, coumarone resin and phenolic resin. A rubber compounding is carried out in an internal mixer. The second mixing is carried out on an open mill. The temperature of the open mill should not exceed 50 ° C.
