The invention relates to a PAM anionic liquid thickener, and belongs to the technical field of building concrete admixtures. ThePAM anionic liquid thickener can increase binding power of concrete and reduce the collapse degree, and comprises the following raw material components in parts by weight: 10-25 parts of acrylamide, 1-4 parts of a surfactant, 2-6 parts of an initiator and 60-100 parts of water. The method comprises: (1) putting water, acrylamide, an initiator and a surfactant into a reaction kettle according to the component ratio, and mixing; (2) carrying out polymerization reaction at a temperature of 50 to 60 DEG C for 1 to 1.5 hours; and (3) carrying out viscosity detection on the product obtained in the step (2), and packaging the product with the viscosity reaching 60-90 Pa.s to obtain a finished product.
