Study on the preparation of suspension stabilizer for liquid accelerator

摘要

A suspension stabilizer(P-XF)was prepared by copolymerization of acrylamide(AM),acrylic acid(AA),ammonium persulfate(APS),thioglycolic acid(TGA)and potassium hydrogen tartrate(KHT).The suspension stabilizer(P-XF),aluminum sulfate(Al2(SO4)3),p-toluenesulfonic acid(PTSA)and triethanolamine(TEA)were used to prepare a liquid accelerator(P-SN2).The test results show that compared with the liquid accelerator(P-SN1)without P-XF,P-SN2 not only can effectively shorten the setting time,but also has high stability,with a stable period of more than one year.
