Abstract：Based on the synthesis mechanism of melamine water reducing agent,WS-SM melamine water reducing agent was synthesized by taking melamine and formaldehyde,liquid alkali,sulfuric acid and glycol as raw materials. Test results show that when the dosage of melamine and formaldehyde mol ratio is 1.0:3.5;composite sulfonating agent and melamine mol ratio is 2.0:1.0, stable temperature at 90℃,the pH control at 12;condensation temperature control at 60℃,the pH control at about 5,the obtained melamine water reducing agent has the best dispersibility. The water reducing rate,storage time,compatibility,and stability of performance of the melamine water reducing agent obtained by this synthesis process are superior to that of the existing melamine water reducing agent available on the market.
