Attapulgite binder for light strips used for building walls

Abstract

The invention discloses an attapulgite binder for light strips used for building walls. The binder is composed of the following raw materials by weight parts: 120-150 parts of 32.5 rapid-hardening aluminum sulfate cement, 10-15 parts of copolymer rubber powder of styrene and butadiene, 100-150 parts of quartz sand, 4-6 parts of vegetable fibers, 3-5 parts of alum stone powder, 4-8 parts of limestone powder, 15-20 parts of instant powdered sodium silicate, 5-10 parts of dolomite powder, 10-15 parts of the attapulgite and 4-8 parts of slag powder. The attapulgite binder for the light strips used for the building walls is strong in bond strength, and can reduce layering and spalling, guarantee engineering quality, prevent problems of hollowing, cracking and other problems after a long-term use, and thus improve endurance. The binder provided by the invention is pre-mixed in a dry way, is stable in quality, can be added with a proper amount of water to stir for using, and thus is simple and convenient to construct. The binder effectively utilizes the slag powder and other waste materials, is free of poisonous and harmful additives, totally meets requirements of environmental protection, and is safe and non-polluted.

Description

Technical field [0001] The invention relates to a binder for building materials, in particular to a lightweight attapulgite clay binder for building partition walls. Background technique [0002] Lightweight slats for building partition walls are made of ordinary Portland cement as the cementing material, and light aggregates such as ceramsite, expanded perlite, and industrial ash as the main raw materials, and are produced by extrusion molding. board. A certain amount of adhesive is required for fixing during 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 adhesive for building partition walls. Summary of the invention [0003] The purpose of the present invention is to provi...
