Bauxite binder for light batten of building partition wall

Abstract

The invention discloses a bauxite binder for a light batten of a building partition wall. The bauxite binder comprises, by weight, 110 to 140 parts of 42.5 ordinary portland cement, 15 to 20 parts of vinyl acetate-higher fatty acid vinyl ester copolymer powder, 120 to 160 parts of quartz sand, 5 to 8 parts of vegetable fibers, 4 to 6 parts of quicklime, 5 to 8 parts of gypsum, 20 to 25 parts of instant powdery sodium silicate, 8 to 12 parts of potash feldspar powder, 15 to 20 parts of bauxite, 5 to 10 parts of coal ash, and 2 to 3 parts of polyvinyl alcohol. The bauxite binder for a light batten of a building partition wall has strong cohesion, reduces layering and peeling opportunity, guarantees engineering quality, avoids hollowing and cracking after long-term use, and improves endurance. The bauxite binder is subjected to advance dry mixing and has stable quality. After being mixed with an appropriate amount of water, the bauxite binder can be used and is convenient for construction. The bauxite binder effectively utilizes waste materials such as coal ash, does not contain poisonous and harmful additives, satisfies environmental protection requirements, is safe and has no pollution.

Description

technical field [0001] The invention relates to a binder for building materials, in particular to a light-weight lath bauxite binder for building partition walls. Background technique [0002] Lightweight strips for building partition walls are porous hollow strips produced by extrusion molding with ordinary Portland cement as the cementitious material and light aggregates such as ceramsite, expanded perlite, and industrial ash as the main raw materials. plate. A certain amount of adhesive is required for its construction and installation. However, the existing adhesives have disadvantages such as low construction efficiency, poor adhesion, poor durability and poor safety, and cannot meet the bonding requirements of lightweight strips for building partition walls. Therefore, there is an urgent need to research and develop a new high-performance lightweight strip adhesive for building partition walls.
