The invention discloses an anti-crack modifier for cement; the anti-crack modifier is prepared from the following raw materials in parts by weight: 1.5-4.5 parts of (hydroxyethylidene)diphosphonic acid, 2.4-3.8 parts of coconut diethanolamide, 5-10 parts of deionized water, 2.7-4.4 parts of calcium lignosulphonate, 1.2-2.6 parts of a lime powder, 0.5-1.6 parts of polyisobutene, 1-2.3 parts of an alpha-methylstyrene polymer, and 1.5-2.2 parts of dodecyl trimethyl ammonium chloride. The anti-crack modifier is low in cost, and can better solve the technical problems of cement hardening, poor waterproofness, small cohesive force, no abrasion resistance, no freeze resistance and the like; and through a large number of experiments, after the modifier is added in ordinary cement, the above properties of the ordinary cement are all relatively greatly improved.
