分散剂PL-60的主要化学成分为脂肪酸皂和酰胺类的聚合物,其对于提高胶料的流动性具有很高的效能。其中的机理主要为降低分子间的摩擦力,以及胶料与金属表面的摩擦力,从而达到增加流动的目的。此外,分散剂PL-60对于IIR聚合物中重结晶的趋向,具有抑制和稳定的作用;对于混炼期间及硫化过后的胶料脱模性有提高的效果,可消除粘辊筒及粘模具的现象,可在混炼的任何阶段加入,但在混炼最后阶段加入,脱模效果最佳;在丁基橡胶内胎中使用分散剂PL-60,可增强胶料的流动性,减少模具锅锈,提高产品外观质量和接头强力,使产品外观光滑致密,色泽鲜艳。
The main chemical component of dispersant PL-60 is a polymer of fatty acid soaps and amides, which has high performance for improving the fluidity of compound. The mechanism is mainly to reduce the friction between molecules, as well as rubber and metal surface friction, so as to achieve the purpose of increasing the flow. In addition, dispersant PL-60 has an inhibitory and stabilizing effect on the tendency of recrystallization in IIR polymers; it has the effect of improving the mold releasability during kneading and after vulcanization, Of the phenomenon, can be added at any stage of mixing, but in the final stage of mixing added, stripping the best results; in the use of butyl rubber tube dispersant PL-60, can enhance the fluidity of rubber, reduce mold pot Rust, improve the appearance of the product quality and strong joints, the product looks smooth and compact, bright color.
