Study on the preparation of suspension stabilizer for liquid accelerator

Abstract

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.
