摘要:
采用低温制备低磺化度的甲醛、丙酮预聚磺化混合物和采用中温磺化丙酮的分步合成方式，获得了减水率高，保坍性能较好的脂肪族减水剂.实验研究了原材料配比、反应浓度等对分散性能的影响，结果表明，当磺化剂用量与丙酮的摩尔比为0.67，醛酮摩尔比为2.0，两部分丙酮（A1/A2）摩尔比为0.33，两部分磺化剂（S1/S2）摩尔比为0.55，反应浓度为34%时合成的减水剂效果最好，所得结果对脂肪族磺酸盐高效减水剂的合成具有重要的指导意义.
Abstract:
In this study, preparing the formaldehyde, acetone prepolymer sulfonated mixture by low temperature and sulfonated acetone by medium temperature, so that it can obtain aliphatic water reducer with high water reducing rate and lower slump loss. The factors which affect the dispersion performance, such as the ratio of raw materials and the reaction concentration have been studied.Test result shows that the superplasticizer has the best performance when the molar ratio of sulfonating agent dosage and acetone is 0.67, aldehyde ketone mole ratio is 2.0, two parts of acetone (A1/A2) mole ratio is 0.33, the two parts of sulfonating agent (S1/S2) mole ratio is 0.55, and reaction concentration is 34%, and the results have important guiding significance for the synthesis of aliphatic sulfonate high efficiency water reducing agent.
