Abstract

The invention discloses a light board attapulgite binder for building partition walls. The binder is composed of the following raw materials: by weight, 120-150 parts of 32.5 rapid hardening aluminum sulfate salt cement, 40-50 parts of pure acrylic emulsion, 4-6 parts of polyvinyl alcohol, 3-4 parts of diethylene glycol, 2-3 parts of hydroxyethyl methyl cellulose, 100-150 parts of silica sand, 4-6 parts of plant fiber, 3-5 parts of alunite powder, 4-8 parts of benzenesulfonyl hydrazide, 5-10 parts of dolomite powder, 10-15 parts of attapulgite, 4-8 parts of furnace slag powder, 1-2 parts of sodium borate, 5-8 parts of triethanolamine, 0.5-1 parts of 3-aminopropyl trimethoxy silane. The light board attapulgite binder for building partition walls has strong adhesion, reduces chances of delamination and spalling, guarantees engineering quality, avoids the problems of hollowing and cracking after long-term usage, and therefore raises the durability.

Description

technical field [0001] The invention relates to a binder for building materials, in particular to a lightweight strip attapulgite 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. Contents of the invention [0003] The object of the present inven...
