The invention discloses a novel cement crack resistance modifier. The modifier is prepared from the following raw materials, by weight, 1.5-4.5 parts of amino silicone oil microemulsion, 2.4-3.8 parts of coconut diethanolamide, 5-10 parts of deionized water, 2.7-4.4 parts of calcium lignosulfonate, 1.2-2.6 parts of pulverized lime, 0.5-1.6 parts of glucose, 1-2.3 parts of styrene-isoprene-styrene copolymer and 1.5-2.2 parts of dodecyl trimethyl ammonium chloride. The novel cement crack resistance modifier is inexpensive, and well solves the technical problems of cement hardening, poor water resistance, small adhesion stress, low wear resistance and low antifreeze property; and a lot of tests verify that the above performances of common cement are greatly improved after the novel cement crack resistance modifier is added to the common cement.
