The invention discloses a modified cement antifreeze modifier. The modified cement antifreeze modifier is prepared by using the following raw materials, by weight, 1.5-3.5 parts of asbestos, 2.5-3.8 parts of nonylphenol ether methyl phosphate ethanolamine salt, 2.5-5 parts of furan resin, 0.5-1.2 parts of 2-ethylformic acid, 1.5-2.2 parts of stearic acid, 1.8-3.3 parts of phenylacetic acid, 1.2-1.8 parts of tributyl phenol polyoxyethylene ether and 3.5-5.2 parts of N-methylfatty amido taurate. Compared with present cement modifiers, the modified cement antifreeze modifier has the advantages of low cost, solving of the technical problems of poor hardening and water resistance, small adhesion stress, low wear resistance and poor antifreeze property, and great improvement of the above performances of common cement after verification of massive tests.
