摘要
将丁苯胶乳(SBR)、预处理剂、多元隔离剂、复配型防老剂、脱盐水等,按配方加入7.8m3凝聚釜中,在一定的温度下,喷入凝聚剂(一价金属盐溶液)。当凝聚过程出现明显絮凝时,再一次喷入凝聚剂(二价金属盐溶液),待胶乳凝析完全后,升温并加入成型剂。经恒温处理的淤浆,降温排入淤浆槽,并加入防粘剂。淤浆经离心、洗涤、脱水,形成SBR滤饼,然后通过研磨机研磨,进入旋转闪蒸干燥器干燥,即制得粉末丁苯橡胶产品。产品收率超过90%,水分不超过1.5%,98.5%的产物粒径小于1.25mm。
The powdered styrene-butadiene rubber was prepared using styrene-butadiene rubber latex, pretreatment (agent), multi-insulator, compounded antioxidant, desalted water and etc. The product yield was more than 90%, moisture content was less than 1.0% and the particle size of (98.5%) product was less than 1.25mm.
