针对部分提质褐煤型煤防水性差的缺点,制备乳化硅油作为型煤的防水剂,在硅油乳液的制备过程中,最佳亲水亲油平衡值(HLB)为10.5,硅油与乳化剂的最佳质量比为4∶1,最佳乳化方式为转相乳化法。试验结果表明:乳化硅油作为防水剂可大幅度增强提质褐煤型煤的防水性,3种不同质量分数的硅油乳液(5%、10%、30%)分别可使原本不具有防水性的型煤60 m in的平均吸水率降至6.98%、5.51%和1.98%。

According to the poor water proofing shortage of partial upgraded lignite briquette, the emulsified silicon oil was prepared to be the water proofing agent of the briquette.During the preparation process of the silicon oil emulsion, the best hydrophilic lipophilic balance value would be 10.5, the best quality ratio of the silicon oil and the emulsifier would be 4 : 1 and the best emulsification method would be the phase inversion emulsification method.The experiment results showed that the em ulsified silicon oil as the water proofing agent could highly improve and upgrade the water resistance of the lignite briquette and three silicon oils with different quality fr actions (5%，10% and 30%) could make the briquettes previously with no water resistance to have an average 60 minutes water absorption rate reduced to 6.98%，5.5 1% and 1.98% individually.
