摘　　要：以木质素磺酸钠作为原料，经过甲醛和亚硫酸钠磺甲基化改性得到改性后的木质素磺酸钠，研究不同的磺甲基化条件对改性后的木质素磺酸钠耐热稳定性和分散磨效的影响。The modified sodium lignosulphonate was obtained through the sulfomethylation of the formaldehyde and sodium sulfite. Then the effects of the different conditions of sulfomethylation on the heat stability and the dispersion and grinding property of the modified sodium lignosulphonate were studied.

关 键 词：木质素磺酸钠 磺甲基化 分散磨效 耐热稳定性
