摘　　要：以α-甲基丙烯酸、丙烯磺酸钠、甲基丙烯酰氧乙基三甲基氯化铵、苯乙烯为原料,合成2种新型水煤浆分散剂,用于水煤浆制浆,测试添加这2种分散剂制得的水煤浆的各项性能,并对产物进行了分析。研究发现,2种分散剂性质稳定,均可用在较苛刻的环境,并不同程度改善了水煤浆性能,具有很好的降黏效果,并明显增强了浆体的静态稳定性。Two new coal-water slurry dispersants synthesized by methyl acrylic acid （MAA）, sodium allyl sulfonat（SAS）, methacryloxyethyltrimethyl ammonium chloride （DMC） and styrene, are used for the preparation of coal water slurry. And the performance of the prepared coal-water slurry is analyzed. It is found that both dispersants have steady properties and can be used in harsh environment, and they can improve performances of coal water slurry to a different degrees, with satisfying effects of cutting down the visconsity and ability to enhance the static stability of coal water slurry.
