摘　　要：以海水、贝壳和冰醋酸等为主要原料,制备CMA环保型融雪剂。实验得出CMA的最佳制备条件:以1g氧化钙为例,氢氧化镁与氧化钙的配比为0.2/1(g/g),10mol/L的冰醋酸5m L及15m L的水。对CMA融雪剂进行了性能测试,结果表明:CMA融雪剂各项性能均优于氯化钠融雪剂。The preparation process of environment -friendly CMA snow -melting agent by shell,seawater and glacial acetic acid as main raw materials was presented.The observed optimal operation conditions were as follows：the ratio of calcium hydroxide and magnesium hydroxide was 0.2∶1 （g/g） （on the basis of 1g calcium oxide）,5ml glacial acetic acid （10mol /L）and 15ml water.Performance of CMA snow -melting agent was tested and compared with sodium chloride.The results showed that the performances of CMA snow -melting agent were better than sodium chloride.
