摘　　要：针对现有型煤防水性差、灰分高、强度低等问题,以有机物为原料,型煤落下强度为参考指标,研究了黏结剂配比、NaOH添加量、焖料时间、干馏温度等因素对型煤黏结剂性能的影响,得到了型煤复合黏结剂配方和型煤生产工艺条件,并分析了黏结剂对设备的腐蚀情况。结果表明,型煤黏结剂的最佳配方为:聚丙烯酰胺、玉米氧化淀粉、羧甲基纤维素、黄糊精、聚乙烯醇质量比为1.0∶1.25∶0.75∶2.0∶5.0,NaOH最佳添加量为0.26%,最佳焖料时间为2h,型煤全水分应控制在15%左右,干馏最佳温度为700℃,在此条件下制备的型煤强度能满足工业生产要求。最佳工艺条件下黏结剂的成分对沥青漆涂层和金属设备影响不大,满足生产工艺需求。In order to improve water resistance,strength of briquette and decrease its ash,taking organic material as a raw material and dropping strength as reference index,the influence of ratio of binder,NaOH addition amount,reaction time and carbonization temperature etc. on properties of briquette binder was studied. The optimum proportion of the binder and production process conditions of the briquette were determined. The corrosion of the binder to equipment was analyzed. The results showed that the mass ratio of yellow dextrin,PAM,CMC,corn starch and PVA was 1. 0∶ 1. 25∶ 0. 75∶ 2. 0∶ 5. 0. The optimal addition amount of alkali was 0. 26% when the braised time was 2 h. Total moisture content should be controlled at around 15% in the briquette,and the optimum temperature of carbonization was700 ℃. The briquette strength under this condition met industrial production requirement. The ultimate binder had little effects on the asphalt lacquer coating and metal equipment.
