羧基丁苯高固胶乳海绵配合物配方设计

Formulating of recipe for carbonyl SBR high solid content latex sponge compounding addictive

以热法羧基丁苯高固胶乳为主 ( 70份 ) ,复配少量天然胶乳 ( 30份 ) ,采用非胶凝体系 ,以机械方式起泡 ,对海绵配合物的起泡体系和硫化体系进行了研究。起泡体系以 4份起泡剂A和 0 .8份起泡剂B或起泡剂C组成 ;硫化体系采用超高促进剂类型 ,ZDC/MZ或ZDC/M配型满足硫化速度要求 ;用填充剂A作填充剂 ,可以满足压花成型性的特殊要求。工业实验结果比小试结果更佳 ,制得了泡孔密度均匀、柔软、弹性好的海绵背衬地毯。

Bubbling and vulcanization system of sponge compounding addictive with 70 phr of thermal-process carbonyl SBR high solid content latex and 30 phr of natural latex by gel-free system and mechanical bubbling process were investigated. Bubbling system was composed of 4 phr of foamer A and 0.8 phr of foamer B or C; Super-high accelerator ZDC/MA or ZDC/M was used in vulcanization system to meet the requirements of vulcanization rate, and filling agent A was used to meet the special requirements such as embossed shaping. Commercial experiment had better results than that of bench test. Soft sponge back-lining carpet with symmetrical bubble hole density and high elasticity carpet was produced.
