The invention discloses an improved freeze-resistant cement modifier. The improved freeze-resistant cement modifier is prepared from the following raw materials in parts by weight: 1.2-3.4 parts of silica, 2.5-5 parts of maleic anhydride, 3.2-4.7 parts of vinyl acetate, 1.2-2.4 parts of sodium acetate, 2.5-5 parts of periodate lignin, 0.8-1.6 parts of gamma-mercaptopropyl trimethoxysilane and 1.2-3.5 parts of polyamide urea-formaldehyde resin. Compared with the existing improved freeze-resistant cement modifiers, the modifier disclosed by the invention has the advantages that the cost is low, and the technical problems of cement hardening, poor waterproofing property, low bonding power, no wear resistance, no freezing resistance and the like are better solved; verified by a large number of tests, the properties of normal cement are greatly improved after the modifier disclosed by the invention is added into the normal cement.
