Embodiment 1

[0033] A gypsum-based self-leveling mortar, including the following components: 40 kg of anhydrite, 4 kg of cement, 20 kg of 40-mesh quartz sand, 20 kg of 80-mesh quartz sand, 0.06 kg of retarder, 0.06 kg of water reducing agent, water retention agent 0.08 kg, 0.05 kg of defoamer, 2 kg of redispersible rubber powder. During preparation, each component is weighed and mixed according to the proportion to obtain a gypsum-based self-leveling mortar.

Embodiment 2

[0035] A gypsum-based self-leveling mortar, including the following components: 60 kg of anhydrite, 6 kg of cement, 30 kg of 80-mesh quartz sand, 30 kg of 120-mesh quartz sand, 0.10 kg of retarder, 0.08 kg of water reducing agent, and water retaining agent 0.10 kg, 0.08 kg of defoamer, 3 kg of redispersible rubber powder. During preparation, each component is weighed and mixed according to the proportion to obtain a gypsum-based self-leveling mortar.

Embodiment 3

[0037] A gypsum-based self-leveling mortar, including the following components: 50 kg of anhydrite, 5 kg of cement, 25 kg of 60-mesh quartz sand, 25 kg of 100-mesh quartz sand, 0.08 kg of retarder, 0.07 kg of water reducing agent, and water retaining agent 0.09 kg, 0.06 kg of defoamer, 2.5 kg of redispersible rubber powder. During preparation, each component is weighed and mixed according to the proportion to obtain a gypsum-based self-leveling mortar.

[0038] The gypsum-based self-leveling mortar of the invention is simple to use. When in use, the surface of the object to be used can be treated and used directly. The gypsum-based self-leveling mortar is mixed with water and then applied to the surface. For example, the ground is treated and directly used on the ground.

Abstract

The invention relates to gypsum-based self-leveling mortar and a preparation method thereof. The gypsum-based self-leveling mortar comprises, by weight, 40-60 parts of anhydrite, 4-6 parts of cement,40-60 parts of quartz sand, 0.06-0.10 part of retarder, 0.06-0.08 part of water reducing agent, 0.08-0.10 part of water-retaining agent, 0.05-0.08 part of defoaming agent and 2-3 parts of redispersible latex powder. The preparation method includes: weighing the components according to the weight, and evenly mixing to obtain the gypsum-based self-leveling mortar. The gypsum-based self-leveling mortar is good in thermal insulation and sound insulation performance, capable of effectively increasing construction speed during use, capable of saving a large amount of manpower and capable of increasing the flatness of leveling operation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a gypsum-based self-leveling mortar and a preparation method thereof. Background technique [0002] At present, in the construction of buildings in our country, cement mortar is still basically used and traditional manual methods are used to make the leveling layer, and there are quality defects such as empty drums, cracks, and leakage to varying degrees, which seriously restrict the use of the roof waterproof layer. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of gypsum-based self-leveling mortar. The gypsum-based self-leveling mortar produced by the preparation method has good thermal insulation performance, effectively improves the construction speed during use, and saves a lot of man-hours. Improve the smoothness of leveling work. [0004] The technical scheme that the present inventio...
