Abstract

The invention discloses a modified silicone oil water repellent agent, a preparation method thereof, waterproof mortar prepared from the water repellent agent, and a preparation method of the waterproof mortar. The water repellent agent comprises polymethylsiloxane, 1-heptene, trichlorotert-butyl alcohol and chloroplatinic acid isopropanol. The preparation method comprises the following steps: mixing and stirring polymethylsiloxane and 1-heptene, adding chloroplatinic acid isopropanol, carrying out a reaction, adding trichlorotert-butyl alcohol, and continuously stirring the mixture; wherein the waterproof mortar comprises cement, graded sand, silica fume, fly ash, clay, titanium dioxide, cellulose ether, redispersible latex powder, polypropylene fiber, a polycarboxylate superplasticizer,an antifoaming agent and a hydrophobic agent. The preparation method of the waterproof mortar comprises the following steps: uniformly mixing the rest raw materials to obtain powder, and adding the water repellent agent and water to obtain the waterproof mortar. The hydrophobic agent provided by the invention has excellent hydrophobic performance, and the waterproof mortar prepared from the hydrophobic agent has excellent impermeability.

Description

technical field [0001] The invention belongs to the field of mortar preparation, and in particular relates to a modified silicone oil hydrophobic agent and its preparation method, and waterproof mortar prepared by using the hydrophobic agent and its preparation method. Background technique [0002] Effectively solving the leakage of building structures and prolonging the life of buildings has always been a difficult problem in construction technology. In addition to achieving waterproof and anti-seepage through dense structures, the use of waterproof materials has become an indispensable means of waterproofing. Unlike the traditional waterproofing of only cement-based hydraulic materials, polymer cement waterproof mortar contains both inorganic hydraulic gelling materials and organic polymer resins. The inorganic binder cement can provide a water-resistant skeleton and a bond with the base surface. Mechanical cohesion, long-term durability and strength growth; the polymer ca...
