Example Embodiment

[0023] Example 1

[0024] The method for making crack-proof and long-life door and window caulking and sealing mortar consists of the following steps:

[0025] (1) Preparation of active mixed solid material: Mix active silica, quartz sand, diatomite, air-entraining agent, water reducing agent and hydrophobic powder evenly.

[0026] (2) Preparation of mixed solution: Dissolve K-11 mortar anti-cracking agent in an appropriate amount of water, and the amount of water added is 30%-40% of the cement consumption.

[0027] (3) Preparation of slurry: in the stirring state, the mixed liquid, cement and active mixed material are respectively injected into the twin-shaft mixer through the water pump and the injector according to the stated ratio, and the cement mortar of the present invention is prepared by stirring evenly; wherein The input frequency of water addition, material injection and the power supply of the stirring machine are all controlled within the range of 50-60Hz.

Abstract

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.

Description

technical field [0001] The invention relates to a preparation method of sealing mortar, in particular to a preparation method of anti-cracking and long-life door and window joint sealing mortar. Background technique [0002] At present, the materials for window filling treatment are cement mortar, caulking, foaming and so on. But which material is better to choose? Due to the high cost of caulking, foaming and other materials, the cost will basically increase by 3-5 yuan per square meter; and because the construction of cement mortar joint filling is the simplest and most practical, many companies use cement mortar for filling . [0003] However, the cement mortar corrodes and pollutes the decorative surface of aluminum doors and windows and the inner surface of door and window frame profiles. Although cement mortar is easy to corrode the inner surface (non-decorative surface) of door and window frame profiles; but according to the data, when the cement mortar is not so...
