Abstract

The invention discloses tile bonding glue prepared from red mud. The tile bonding glue is mainly prepared from the following raw materials in parts by weight: 10-15 parts of dry powder water glass, 30-40 parts of red mud, 30-40 parts of superfine slag powder, 5-10 parts of metakaolin, 2-5 parts of fly ash, 2-5 parts of gypsum powder, 1-3 parts of silica fume, 1-3 parts of latex powder, 0.2-0.7 part of a water-retaining agent, 1-2 parts of a retarder and 120-180 parts of aggregates. By taking red mud as the main raw material, the prepared binder product has good performance; through test, the initial tensile strength of a binder is 0.7MPa, the tensile strength of the binder after waterproofing treatment reaches 0.5MPa, and the binder has good freeze-thawing resistance; prepared bonding mortar is easy to construct, good in flow fall resistance and low in cost, and the consumption of the red mud is high. Besides, by taking industrial waste residues as the main raw materials, sources are very wide, and the production process is environmentally friendly.

Description

technical field [0001] The invention relates to a dry-mixed mortar tile adhesive, in particular to a tile adhesive using red mud as a raw material, and belongs to the technical field of new materials. Background technique [0002] Tile adhesive is a cement-based high-quality adhesive modified by polymers. It is flexible and quick-drying. It is suitable for thick and thin construction. Its special formula enables it to paste tiles on various types of substrates. It is composed of cement, quartz sand and concentrated tackifier. Traditional tile adhesives mostly use cement mortar, which has weak cohesive force, poor durability, and is easy to peel off. Moreover, the method of mixing and thick layer construction is used, and the ratio is unstable, which affects the durability of tiles and wastes raw materials. , It also affects the construction speed, pollutes the environment, its safety cannot be guaranteed, and safety accidents are prone to occur. [0003] Red mud is an indu...
