摘要
以环氧氯丙烷和二乙醇胺为原料,以水为溶剂,合成了特性黏数小、防膨率高的黏土稳定剂———聚2-羟亚丙基二羟乙基氯化铵.考察了环氧氯丙烷(ECH)与二乙醇胺(DEA)的物质的量比、二乙醇胺的质量分数、加料温度、反应温度、反应时间等因素对聚合物防膨率的影响.结果表明:当聚合物的特性黏数为2.43 dL/g,聚合物质量分数为3%时,防膨率达到了83.5%.
A clay stabilizer-Poly2-hydroxylproylidene dihydroxyethyl ammonium chloride with low molecular mass and high swelling prevention ratio is prepared from epichlorohydrin and diethanolamine and water as solvent.The factors such as mole ratio of epichlorohydrin(ECH) and diethanolamine(DEA),diethanolamine's mass fraction,entering chemicals temperature,reaction temperature,reaction time on the swelling prevention ratio are investigated via the condition experiment.The polymers are a good clay stabilizer.The result indicates that intrinsic viscosity of polymers is 2.43 dL/g and the swelling prevention ratio of the polymer may achieve 83.5% when the concentration of polymer is 3%.
