Problems solved by technology

[0003] However, light-weight partition wall slats often have cracks in the board seams. The cracking phenomena mainly include: cracks in the board seams between wall panels; cracks in the upper corners of the door and window openings; cracks in the connection between wall panels and structural parts; Plastering surface cracks, etc.
Thereby cause inconvenient to use, serious person causes potential safety hazard
[0004] At present, the joint bonding of lightweight partition wall slats used in the market is commonly used as ordinary bonding mortar or anti-cracking mortar. The bonding and caulking functions are related to the physical changes of the wallboard material There are some unsuitable defects, such as insufficient bonding strength, poor toughness and other defects; at the same time, there are also problems that it is not easy to fill and compact
Therefore, it is impossible to meet the requirements of the seam filling operation for lightweight wall panels

Abstract

A light partition wall crack filling mortar and a preparation method thereof belong to the field of building materials. The light partition wall crack filling mortar is prepared from raw materials including, by weight part, 80-110 parts of aluminate cement, 340-380 parts of ordinary Portland cement, 25-30 parts of calcium sulfate whisker, 18-22 parts of anhydrous sodium sulfate, 150-180 parts of fine sand, 200-240 parts of medium sand, 120-140 parts of coarse sand, 50-75 parts of coal ash, 2-8 parts of cellulose ether and 38-45 parts of rubber powder. The light partition wall crack filling mortar has the advantages of being high in bonding strength, good in tenacity, compact in crack filling and the like. The preparation method of the light partition wall crack filling mortar comprises mixing the raw 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 joint-filling mortar for treating cracks in 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 costs 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, light...
