Zeolite cement mortar waterproof agent and preparation method thereof

The invention discloses a zeolite cement mortar waterproof agent and a preparation method thereof, and belongs to the technical field of cement mortar waterproof agents. The waterproof agent is characterized by comprising the following components in parts by weight: 88-91 parts of activated modified zeolite, 1-3 parts of levigated polyvinyl alcohol, 5-7 parts of vinyl acetate copolymer, and 1-3 parts of aluminium sulfate. The preparation method of the zeolite cement mortar waterproof agent comprises the following steps: 1, the activation and roasting of zeolite powder; 2, the surface modification of the activated modified zeolite; 3, high-speed mixing, and packaging of finished products. According to the invention, the defects of the cement mortar waterproof agent in the prior art can be overcome, and the activated modified zeolite which is subjected to surface modification and used as the main raw material is natural mineral, has no toxicity or undesirable odor, and is safe and environment-friendly; the uniformity and workability of concrete mixture can be improved, the heat of hydration is reduced, the strength, anti-permeability and durability of concrete can be improved, and the concrete alkali-aggregate reaction can also be inhibited.
