Abstract

Disclosed is a method of preparing an eco-friendly reinforced alkali-free liquid accelerator, including steps of: acylating urea with maleic anhydride to produce an acylated product; copolymerizing the acylated product with acrylamide and acrylic acid to prepare a suspension stabilizer; and applying the suspension stabilizer in the preparation of the alkali-free liquid accelerator. The suspension stabilizer is provided with an amide structure through the introduction of the acylation of maleic anhydride and urea, thereby improving the cohesiveness of the liquid accelerator, effectively inhibiting the formation of precipitate and greatly promoting the storage stability of the mother liquor. The stability can be kept for more than 15 months. Moreover, the amide structure and urea can promote the early strength, thus improving the early strength of concrete.
