The invention discloses a cement anti-cracking modifier. The cement anti-cracking modifier is prepared from following raw materials, by weight, 1.5 to 4.5 parts of sodium molybdate, 2.4 to 3.8 parts of cocomut oil die thanolamide, 5 to 10 parts of deionized water, 2.7 to 4.4 parts of calcium lignosulphonate, 1.2 to 2.6 parts of lime powder, 0.5 to 1.6 parts of polyisobutylene, 1 to 2.3 parts of styrene-isoprene- styrene copolymer, and 1.5 to 2.2 parts of dodecyl trimethyl ammonium chloride. The cement anti-cracking modifier is low in cost, and is capable of solving technical problems such as cement hardening, poor water resistance, low adhesion stress, low wear resistance, and poor frost resistance; and it is confirmed by a large amount of experiments that performance of common cement can be improved greatly after adding of the cement anti-cracking modifier into common cement.
