Abstract

The invention discloses a cement additive and a preparation method thereof. The cement additive comprises the following components, by weight: 15-20 parts of acrylamide, 40-60 parts of xylene, 5-10 parts of organic boron, 10-20 parts of triethanolamine, 10-20 parts of urea, 0.5-2 parts of mirabilite, 3-6 parts of gypsum, 12-30 parts of calcium chloride, 3-10 parts of sodium acetate, and 100-150 parts of water. The additive has the following advantages: when the additive is added into cement, the volume of the additive is expanded, such that cement gas channeling can be effectively prevented, while cement body strength can be improved. The method is simple and feasible; investment is low; and the method is easy to realize.
