Crack-resistant long-life door and window joint filling and sealing mortar manufacturing method
The invention discloses a crack-resistant long-life door and window joint filling and sealing mortar manufacturing method. A problem that comprehensive performances of present cement mortars often cannot reach demands when the cement mortars are used in the door and window joint filling treatment is solved. The method comprises the following steps: 1, preparing an active mixed solid material: uniformly mixing active silica, quartz sand, diatomite, an air entraining agent, a water reducer and hydrophobic powder; 2, preparing a mixed solution: dissolving a K-11 mortar crack resisting agent in a proper amount of water, wherein the addition amount of water is 30-40% of the amount of cement; and 3, preparing a mortar: respectively injecting the mixed solution, cement and the active mixed material into a double shaft mixer in a stirring state through a water pump and an injection machine according to a certain ratio, and uniformly stirring to prepare the cement mortar. The cement mortar prepared in the invention has the advantages of excellent waterproof effect, good bonding effect, excellent crack resistance and long service life.
