Self-levelling material and preparation method thereof

Abstract

The invention provides a self-levelling material, which comprises the following components by weight: 250 to 300 grams of ordinary Portland cement, 20 to 100 grams of high-alumina cement, 450 to 500 grams of quartz sand, 40 to 60 grams of anhydrite, 100 to 120 grams of ground calcium carbonate, 0.1 to 1 gram of lithium carbonate, 0.1 to 1 gram of tartaric acid, 0.5 to 1.5 grams of cellulose ether, 5 to 30 grams of latex powder and 1 to 1.5 grams of polycarboxylate water reducer. A preparation method comprises the following steps of: adding the ordinary Portland cement, the high-alumina cement and the quartz sand, stirring uniformly, adding the anhydrite, the ground calcium carbonate, the lithium carbonate, the tartaric acid, the cellulose ether, the latex powder and the polycarboxylate water reducer sequentially, and stirring fully and uniformly. The self-levelling material has high self-levelling performance, stable quality and high construction effect and is easy to construct and manage, and the construction is easy to perform designedly.

Description

Technical field [0001] The invention belongs to the field of building materials, in particular to a self-leveling material and a preparation method thereof. Background technique [0002] The ground self-leveling material is a reform of the traditional ground material. Its use can effectively solve the problems of uneven ground, sanding, pitting, damage and other problems in the construction of the project. It can also be used for repairing old ground such as broken and sanding. . [0003] Self-leveling materials are usually divided into organic and inorganic types. Organic self-leveling materials mainly include epoxy resin self-leveling materials, which have superior performance but high price and high construction requirements. They are mainly used in special occasions. Inorganic self-leveling materials can be divided into It is a gypsum-based self-leveling material and a cement-based self-leveling material. The gypsum-based self-leveling material has poor water resistance and it...

Problems solved by technology

[0003] Self-leveling materials are usually divided into organic and inorganic. Organic self-leveling materials mainly include epoxy resin self-leveling materials, which have superior performance but high prices and high construction requirements. They are mainly used in special occasions. Inorganic self-leveling materials can be divided into It is a gypsum-based self-leveling material and a cement-based self-leveling material. Due to poor water resistance, the acidity of the gypsum-based self-leveling material has a rusting effect on iron products, and the application range is limited. The cement-based self-leveling material can be divided into single-component and There are two types of two-components. Two-component cement-based self-leveling materials are mainly added with polymer emulsion as an independent second component. When used, they are mixed with the first component in a certain proportion. It has good fluidity, fast setting speed, and elasticity. Better, but more expensive, and inconvenient to use and transport, but the existing one-component materials have lower elasticity
