Problems solved by technology

[0003] However, the construction docking of lightweight partition boards has always been a difficult problem that plagues the development of the industry. The thickness of the construction mortar joints between partition boards is generally about 8mm, and the longitudinal mortar joints are long. The use of traditional ordinary cement mortar for docking usually exists. Insufficient cohesion, large volume shrinkage and other shortcomings, longitudinal cracks often appear on the surface of the stress concentration of the wall joints
According to the summary of on-site construction experience, once the width of the entire wall of a wallboard with a width of 60cm exceeds 4.5m, the probability of surface cracking in the middle stress concentration part is more than 80%, and the anti-cracking effect is poor.

Abstract

A light partition wall bonding flexible mortar and a preparation method thereof belong to the field of building materials. The light partition wall bonding flexible mortar is composed of raw materialsincluding, by weight part, 60-90 parts of aluminate cement, 350-420 parts of ordinary Portland cement, 30-35 parts of calcium sulfate whisker, 20-24 parts of anhydrous sodium sulfate, 420-480 parts of sand, 25-35 parts of expanded vermiculite powder, 50-70 parts of ground calcium carbonate, 30-40 parts of calcined kaolin, 5-10 parts of cellulose ether and 35-40 parts of rubber powder. The light partition wall bonding flexible mortar has the advantages of high bonding strength and crack resistance. The preparation method of the light partition wall bonding flexible mortar comprises mixing theraw materials above and is simple in operation.

Description

technical field [0001] The invention relates to the field of building materials, and in particular to a flexible mortar for bonding lightweight partition walls and a preparation method thereof. Background technique [0002] Due to its light weight, sound insulation, heat insulation, moisture resistance, fire prevention and other advantages, the lightweight partition wall panel is easy and fast to construct; it can not only reduce the weight of the building, but also help improve the building function; it can also save engineering cost and reduce energy consumption. It can be widely used in the construction of non-load-bearing walls such as high-rise buildings with frame structures, industrial plants, halls, civil residences, and old house renovations, such as divisions, households, toilets, kitchens, and partitions. It is especially suitable for buildings with high fire protection requirements. For use in public entertainment venues. [0003] However, the construction docki...
