环保型溶聚丁苯橡胶的生产和质量控制

Production and Quality Control of Environmentally Friendly SSBR

介绍环保型溶聚丁苯橡胶(SSBR)的生产和质量控制经验。阐述SSBR合成反应机理,重点分析相对分子质量、结合苯乙烯含量、乙烯基含量、门尼粘度、偶联效率、填充油含量、挥发分含量等对SSBR性能的影响及其控制要点。在实际生产中,对相对分子质量、转化率、门尼粘度、偶联剂用量及偶联效率等主要性能参数的调整应遵循小幅度调节、单个调节的原则,实现SSBR生产和质量的有效控制。

The production and quality control experiences of environmentally friendly solution polymerized styrene butadiene rubber(SSBR)were introduced.The synthesis reaction mechanism of SSBR was described,and the effects of relative molecular weight,bound styrene content,vinyl content,Mooney viscosity,coupling efficiency,filling oil content and volatile matter on the performance of SSBR and their control points were emphatically analyzed.In actual production,the main performance parameters,such as relative molecular weight,conversion rate,Mooney viscosity,coupling agent dosage and coupling efficiency should be adjusted according to the principle of small adjustment and individual adjustment,so as to achieve effective control of SSBR production and quality.
