摘要

Modifying sulphanilic acid-phenol-formaldehyde condensates (SPF) with sodium lignosulphonate (LS) allows for a series of modification products with different contents of LS.The grafting reaction was confirmed during the synthetic process by FTIR.The effects of different contents of LS on ζ potential,paste fluidity,mortar fluidity and bleeding rate was discussed,and comprehensive analysis revealed that SPF contained 30wt％ LS has the optimal cost performance.
