The invention discloses an improved cement crack resistance modifier. The improved cement crack resistance modifier is prepared from the following raw materials in parts by weight: 1.2-3.2 parts of lead salt stabilizer, 0.8-3.6 parts of oil-tea camellia saponin, 3.5-7 parts of butane tetracarboxylic acid, 4-8 parts of kaolin, 1.5-2.7 parts of silica, 1.2-2.8 parts of glyceryl trioleate, 1.5-3.5 parts of polyvinyl acetate and 2.5-4.2 parts of molybdate red. Compared with the existing 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.
