利用含油碳酸钙污泥制备橡胶填充剂

本文以中原油田含油碳酸钙污泥为研究对象,根据高分子理论化学和橡胶工程理论,论证了油田含油碳酸钙污泥开发含油橡胶填充剂的理论基础。经粉体加工,将含油碳酸钙污泥制备成实验用橡胶填充剂。通过橡胶工程实验及产品测试,结果表明,与正在使用的普通碳酸钙和纳米碳酸钙填充剂相比,含油碳酸钙污泥制备的填充剂对橡胶制品的性能没有明显的影响;在分散性、橡胶网状分子的交联性、磨耗、回弹性等方面,较普通碳酸钙和纳米碳酸钙的填充效果稍优。

PRELIMINARY STUDY ON PROCESSING OIL-BASED CALCIUM CARBONATE MUD(OBCCM) INTO RUBBER FILLERS

Based on the theories of macromolecule and rubber engineering,the feasibility that the mud can be processed into rubber fillers is demonstrated.As an example in Zhongyuan Oil Field,SINOPEC,the OBCCM was carefully ground into the powder less than 320 mesh.By the rubber processing and the subsequent product tests,it is suggested that there should be no relations between the quality of the rubber products and the salty contents of the powdery mud,and the heterogeneous ingredients of the powder do not also influence the quality of rubber products seriously.As compared with the rubber fillers of the common and nanometer calcium carbonates,the filling effects of the powder can not be distinguished from processing features and mechanical characters.Moreover,the dispersing trend of the powder in rubber ingerdients,the crosslinking properties of rubber molecules,the anti-abrasion and the rebound are slightly superior to the countparts of the common and nanometer calcium carbonate fillers.
