Abstract

The invention discloses a low temperature quick-setting moistureproof leveling mortar, and belongs to the field of leveling mortar. The low temperature quick-setting moistureproof leveling mortar is composed of a powder material and a liquid material; the powder material is prepared from, by mass, 300 to 500 parts of Portland cement, 3 to 7 parts of a quick-setting early strength agent, 1.5 to 5 parts of a thixotropic lubricating agent, 0.5 to 3 parts of a thickening water-retaining agent, 400 to 600 parts of quartz sand, 0 to 200 parts of calcium powder, and 0 to 1 part of an environment-friendly water reducing agent; the liquid material is prepared from, by mass, 700 to 900 parts of a cationic acrylic emulsion, 3 to 6 parts of an antifoaming agent, 1.5 to 3 parts of a bactericide, 0 to 2 parts of a thickening agent, and 50 to 300 parts of water. The low temperature quick-setting moistureproof leveling mortar possesses low temperature quick setting performance, the lowest construction temperature is 0 DEG C or higher, the low temperature quick-setting moistureproof leveling mortar possesses certain thixotropic lubricity, operation hand feeling is smooth, both time and labour are saved, and moistureproof function is achieved.

Description

technical field [0001] The invention relates to a leveling mortar with low-temperature quick-drying and moisture-proof function, which belongs to the field of leveling mortar. Background technique [0002] At present, the commonly used leveling mortar is divided into two categories: one is cement mortar mixed on site, which is being phased out due to problems such as difficult quality assurance, time-consuming and labor-intensive construction, and dust pollution; the other is special commodity mortar, mainly dry powder mortar , It is made by adding water and stirring on site when using it. Dry powder leveling mortar needs to be added with water. The construction temperature generally requires above 5°C to avoid freezing and cracking problems. However, this kind of mortar has a single function and has no special function except leveling. In addition, during the construction process, except for the roof, balcony, kitchen and bathroom and other areas that have been in contact w...
