Modified oil shale semicoke, preparation method thereof and application of modified oil shale semicoke in rubber

The invention discloses modified oil shale semicoke. The modified oil shale semicoke is oil shale semicoke subjected to 4-hydrazinobenzene sulfonic acid surface modification treatment. The modified oil shale semicoke is obtained by carrying out reflux reaction on oil shale semicoke and 4-hydrazinobenzenesulfonic acid in a solvent. Compared with the prior art, the method has the advantages that the problem of solid waste accumulation of the oil shale semicoke is solved, the environment is protected, the modified oil shale semicoke can partially replace carbon black as a rubber filler, and the rubber production cost is reduced. 本发明公开了一种改性油页岩半焦，该改性油页岩半焦为经过4-肼基苯磺酸表面改性处理的油页岩半焦。该改性油页岩半焦通过油页岩半焦和4-肼基苯磺酸在溶剂中回流反应得到。与现有技术相比，本发明解决了油页岩半焦固废堆积问题，保护了环境，经改性处理后的油页岩半焦作为橡胶填充剂可部分替代炭黑，降低橡胶生产成本。
