Door and window frame joint filling waterproof mortar with strong hydrophobic micro-elastic function

Abstract

The invention discloses door and window frame joint filling waterproof mortar with a strong hydrophobic micro-elastic function. The material comprises a powder material and polyphenyl granules, wherein the ratio of the powder to the polyphenyl granules is (300-400) kg: 1.1 m3; the powder material comprises the following components in percentage by mass: 0.1%-0.5% of hydroxypropyl methyl cellulose,0.1%-0.5% of starch ether, 0.2%-1% of a water repellent agent, 0.1%-0.5% of redispersible latex powder, 0.1%-0.5% of polypropylene fiber, 0.1%-0.5% of wood fiber and 80%-99% of cement. The mortar isprepared from hydroxypropyl methyl cellulose, starch ether, a water repellent agent, redispersible latex powder, polypropylene fibers, wood fibers and cement. By means of the waterproof mortar, the hydrophobicity of the surface of the mortar is improved, the water absorption rate of surface mortar is reduced, and the strength, crack resistance and hydrophobicity of the mortar are guaranteed; and by mixing the polyphenyl granules, the mortar has contractibility, thereby enhancing the moisture resistance and impermeability of the mortar.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a door and window frame seam-filling waterproof mortar with strong hydrophobic and micro-elastic functions. Background technique [0002] At present, waterproof materials such as ordinary cement mortar, ordinary waterproof mortar, and polymer cement waterproof mortar are generally used for repairing and waterproofing of building door and window frame seams at home and abroad. The waterproof principle of this kind of material is to increase the impermeability of the mortar by adding a waterproofing agent, so that it is difficult for external water to penetrate into the mortar and enter the building wall; at the same time, this kind of material has no elasticity, and the expansion and contraction of the wall, doors and windows changes with the seasons. Can cause gaps or cracks in the caulking material. Therefore, how to ensure that the waterproof mortar has a certain sh...
