Abstract

The invention discloses a bentonite binder of a light batten for a building partition. The binder comprises the following raw materials in parts by weight: 100-150 parts of 42.5 common silicate cement, 10-15 parts of vinyl acetate and styrene copolymerized gel powder, 100-120 parts of quartz sand, 4-6 parts of plant fiber, 3-4 parts of alunite powder, 3-5 parts of quick lime, 10-20 parts of instant powder sodium silicate, 8-12 parts of aluminite powder,10-15 parts of bentonite, 5-10 parts of coal ash and 1-2 parts of hydroxyethyl methyl cellulose. The bentonite binder of the light batten for the building partition provided by the invention is strong in binding force, the probability of layering and falling is reduced, the engineering quality is ensured, and the problems of hollowing, cracking and the like after long time use can be avoided, so that the durability is improved. The binder provided by the invention is pre-dry mixed and mixed and is stable in quality; when in use, the kaolin binder is mixed with a proper amount of water and is simple and convenient to construct. Wastes such as slag powder can be effectively utilized, and no toxic or harmful additives are generated, so that the binder completely satisfies the environmental-friendly demand, and is safe and pollution-free.

Description

technical field [0001] The invention relates to a binder for building materials, in particular to a lightweight strip bentonite 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.
