Description

一种以脂肪烃类树脂与芳烃类树脂混合制成石油树脂的制备工艺
技术领域
本发明属于有机合成技术领域，具体涉及一种石油树脂的制备工艺技术。
背景技术
在轮胎工业中，对不同极性及粘度橡胶的混和普遍采用均匀剂。现有技术中普遍采用均匀剂40MSF应用于轮胎胎面胶。均匀剂40MSF是一种进口原料，目前国内尚无企业可以生产。均匀剂40MSF对缩短混炼时间、减低混炼能耗、改善炭黑分散效果、提高胶料混炼均匀性方面效果明显，但其缺点是价格较高。随着原材料价格的上涨，售价高昂的均匀剂40MSF对国内中小型企业显然负担太大。
发明内容
本发明的目的在于提供一种以脂肪烃类树脂与芳烃类树脂混合制成石油树脂的制备工艺，通过该工艺制备的石油树脂，适用于不同橡胶、不同极性、不同粘度的橡胶混合物。
本发明解决其技术问题采用的技术方案是：发明一种以脂肪烃类树脂与芳烃类树脂混合制成石油树脂的制备工艺，以碳五树脂和碳九树脂为主要原料，其特征在于制备工艺按如下步骤依次进行：
(1)以碳五树脂和碳九树脂为原料，在常压反应器中，控制反应温度为180℃-200℃，时间大于或等于2小时，生成脂肪类树脂-芳烃类树脂组成的混合物。
(2)在上述体系中加入橡胶沥青，控制反应温度为180℃-200℃，时间大于或等于2小时，制得成品。
本发明中，各种原料消耗量为：碳五树脂8-10份，碳九树脂60-62份，橡胶沥青30-32份。所述的碳五树脂为从轻油裂解制乙烯的副产液体分离出含有五个碳原子的烃的混合物经催化聚合反应而得。所述的碳九树脂为催化重整和裂解制乙烯副产的含九个碳原子的芳烃馏分经催化聚合反应而得。
制备本发明的消耗原料的性能及要求：
碳五树脂：
结构式
