Abstract

The invention provides an anti-crack binding agent for building partition wall battens. The anti-crack binding agent is prepared from, by weight, 25-35 parts of Portland cement, 5-15 parts of superfine waste powder, 10-65 parts of fine aggregates, 0.8-1.5 parts of rubber powder, 0.05-0.3 part of thickening agent, 0.01-0.1 part of water reducing agent, 0.05-2 parts of expansive agent, 0.05-2.5 parts of calcium formate and 0.05-0.5 part of polypropylene fiber. The anti-crack binding agent for the building partition wall battens has stronger bonding performance and can effectively decrease fissures or cracks of batten joints of the partition wall battens.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-crack adhesive for building partition wall strips. Background technique [0002] With the rapid development of the construction industry today, concrete frame structures and frame-shear structures are the most commonly used building structures in house construction. At the same time, the non-load-bearing partitions used for the division of houses and households are gradually developing from traditional masonry hollow bricks and aerated concrete blocks to various lightweight partition wall slats. The lightweight partition wall slats have light weight and are easy to disassemble and assemble, which is beneficial to reduce the overall load of the building, industrialize the construction of the building, increase the usable area and reduce the effect of wet work. However, cracks and other phenomena often occur in the light-weight partition wall slats, which cause ...
