Dispersant for preparation of polyacrylamide powder by polyacrylamide gel

The invention relates to a dispersant for preparation of a polyacrylamide powder by a polyacrylamide gel, and is used for mainly solving the problems that a dispersant in the prior art adopts kerosene and is not environmentally friendly and safe. The problem is better solved by adopting the technical scheme that the dispersant for preparation of the polyacrylamide powder by the polyacrylamide gel includes the following components in parts by weight: (1) 10 parts of polyethylene glycol; (2) 4-25 parts of water; and (3) 0-1 part of a surfactant. The dispersant can be used in industrial production of preparation of the polyacrylamide powder by the polyacrylamide gel.
