The invention discloses a compression-resistant cement modifier prepared from the following raw materials in parts by weight: 2.5-3.8 parts of chlorinated polyethylene rubber elastomers, 1.5-3.6 parts of polyethylene wax, 2.5-5 parts of zeolite powder, 3-8 parts of dimethyl carbonate, 2.5-5 parts of tribasic lead sulfate, 0.8-2.2 parts of gamma-trimethoxysilylpropanethiol, 1.5-3.6 parts of an aminosilane coupling agent and 3.5-6.8 parts of a bisphenol A epoxy resin aqueous emulsion. Compared with the existing cement modifier, the compression-resistant cement modifier is low in cost and capable of better solving the technical problems such as cement hardening, poor water resistance, small cementing power, no wear resistance and no frost resistance; and a great number of experiments prove that all the performances of Portland cement are greatly improved after the modifier disclosed by the invention is added into the Portland cement.
