Disperse thickening agent for phosphorus gypsum based self-leveling mortar and preparation method
The invention relates to a disperse thickening agent for phosphorus gypsum based self-leveling mortar and a preparation method. The molecular weight of the disperse thickening agent is 110000-260000, the general molecular formula of the disperse thickening agent is shown in the instruction, a=20-45, b=10-20, c=15-35, and d=10-30. The disperse thickening agent has the advantages that the disperse thickening agent has excellent adaptability and large steric hindrance, initial and 30min fluidity can be kept at 150-180mm, exudation and separation are omitted, the water-reducing rate of the prepared disperse thickening agent can reach 27-30%, the strength of the phosphorus gypsum based self-leveling mortar can be effectively enhanced, 1d flexural and compressive strength can reach 155-206% and 144-159%, and absolute dry flexural and compressive strength can reach 134-155% and 146-156%.
