Problems solved by technology

However, the high temperature resistance effect of polystyrene board is extremely poor, and the fire prevention effect is not ideal. It once caused fires in Shanghai, Shenyang and other places, and the country forcibly banned the use of polystyrene board.
The inorganic vitrified bead insulation mortar is relatively safe because it is composed of non-combustible inorganic materials, but its high cost will lead to an increase in the overall cost of the project

Abstract

The invention provides a fireproof interior wall dry-mixed mortar. The fireproof interior wall dry-mixed mortar comprises the following components: Portland cement, quartz sand, a filling material, bentonite, redispersible emulsion powder, cellulose ether, citric acid, and nanoscale titanium dioxide. The product has good adhesion to a base surface, the materials are economic and practical, so that cost is saved, at the same time after the base is treated by the material, phenomena of empty drum and shell do not exist, cleaning of construction site is guaranteed, and environmental protection requirements are met; gangue replaces parts of yellow sand, so that pollution is reduced, cost is reduced, and fireproof effects are realized.

Description

Technical field [0001] The invention belongs to the field of building materials, and specifically relates to a dry-mixed mortar for fire-proof interior walls and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, the requirements for the quality of the construction industry are getting higher and higher. Due to the technical proficiency of the construction personnel and the influence of various raw materials such as cement and sand, the mortar configured on the construction site, whether it is masonry mortar, plastering mortar or ground leveling mortar, often has cracks in building plastering mortar (even if It is the most traditional clay wall bricks that use cement mortar to plaster large areas of cracks), resulting in unstable engineering quality, unsatisfactory strength, and even poor quality. This has become a common problem in building quality. In addition, with the improvement of living standards, people's ...
