【摘要】：采用羟丙基淀粉醚为主要原料,以N,N-亚甲基双丙烯酰胺作交联剂,过硫酸铵作引发剂,羧乙基纤维素钠作粘度调节剂和成膜剂,得到一种保湿性、抗风蚀性、水稳性、耐温性等性能优良的煤炭抑尘剂。通过实验对比,此种抑尘剂在抗风蚀性、水稳性、耐温性方面比纯淀粉基煤炭抑尘剂的各项指标均优。交联反应虽可形成网络结构,提高产物的保湿抗风蚀等性能,也会降低其粘度,不利于成膜性,因此控制交联反应程度为一关键。最佳的反应条件是温度为70℃左右,时间为1h。
[Abstract]:By using hydroxypropyl starch ether as main raw material, Nn- methylene bisacrylamide as crosslinking agent, ammonium persulfate as initiator, sodium carboxyethyl cellulose as viscosity regulator and film forming agent, a kind of moisturizing property, wind erosion resistance and water stability are obtained. Coal dust suppressant with excellent properties such as high temperature resistance. The experimental results show that the dust suppressant is superior to the pure starch based coal dust suppressant in the aspects of wind erosion resistance, water stability and temperature resistance. Although the crosslinking reaction can form a network structure and improve the properties of the product such as moisturizing and wind erosion, it will also reduce its viscosity and be unfavorable to the film-forming property. Therefore, controlling the degree of crosslinking reaction is the key. The optimum reaction conditions are about 70 鈩，
