丁苯胶是我国目前产量最大的通用胶,年产量达20多万 t。在其它橡胶材料资源有限的情况下,开发丁苯胶系列防水材料具有较大的实用价值。QL 型丁苯胶乳沥青防水涂料是由齐鲁石化公司研究院和胜利炼油厂联合研制的,涂料是水乳型冷用胶料。除丁苯胶乳和沥青外,原 SBR is China’s current largest production of general-purpose plastic, the annual output of more than 200,000 t. With the limited resources of other rubber materials, the development of styrene-butadiene rubber waterproof materials has great practical value. QL-type styrene-butadiene latex asphalt waterproof coating was jointly developed by Qilu Petrochemical Company Research Institute and Shengli Refinery. The coating is a cold milk-based rubber compound. Except styrene-butadiene latex and asphalt, the original
