Mortar glue

Abstract

The invention discloses mortar glue. The mortar glue comprises the following components in parts by weight: 17.5 parts-32.5 parts of vinyl acetate glue powder or acrylic acid glue powder, 3.5 parts-6.5 parts of methylcellulose and / or guar gum, 0.35 part-0.65 part of mineral oil and / or organosilicon, 48.3 parts-89.7 parts of calcium carbonate and / or quartz sand and 0.35 part-0.65 part of water reducer. By using the mortar glue, the difficult problems that when cement plaster is fixed on building materials such as ceramic tile and the like, the bond is not firm, empty drum, crack and falling are generated, property is unstable, and the like. The construction performance is good after the mortar glue is added to the cement plaster, the cement plaster has no droop and no sagging, and airing and regulating time is long. Bricks and walls do not need to be wet in the construction process of the cement plaster in which the mortar glue is added, and construction is consistent, thereby improving construction efficiency. The mortar glue disclosed by the invention has the advantages of no toxicity and no peculiar smell, and belongs to environment-friendly products.

Description

technical field [0001] The invention belongs to the technical field of cement mortar for construction, and in particular relates to a mortar glue. Background technique [0002] Cement mortar is the most commonly used building material in construction engineering, and it occupies a large proportion in building materials, and is one of the indispensable building materials. [0003] Chinese invention patent (Patent No. 200610009998.7) discloses a building mortar cementitious material, which is composed of 60-70% by weight of fly ash, 25-35% of cement clinker and 4-6% of additives. The weight percentage composition is 15-25% of hydroxymethyl cellulose, 10-20% of triterpene saponins, 30-40% of calcium lignosulfonate, 15-25% of methylphenylhydrazine hydrochloride and 7-13% of phosphate . The building mortar cementitious material is used in the mortar of masonry and interior wall plastering in industrial and civil buildings. [0004] However, when paving, the above-mentioned bui...

AI Technical Summary

Problems solved by technology

[0004] However, when paving, the above-mentioned building mortar cementitious materials often have defects such as poor bonding, hollowing, cracking, falling off, and unstable performance of cement mortar due to the large temperature difference in the climate and long-term thermal expansion and contraction. Bring many problems to construction technicians

At the same time, the defects of the above-mentioned building mortar cementitious materials also bring great troubles to consumers.
