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 exterior 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, and citric acid. 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 in particular relates to a dry powder mortar for fireproof exterior 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 influence of the technical proficiency of the construction workers and various raw materials such as cement and sand, the mortar used on the construction site, whether it is masonry mortar, plastering mortar or ground leveling mortar, often cracks in the plastering mortar of buildings (even if It is the most traditional clay wall brick that will crack in a large area when it is plastered with cement mortar), resulting in unstable project quality, less than the required strength, and even poor quality, which has become a common problem in construction quality. In addition, with the improvement of l...
