Embodiment 1

[0016] Two-component cement-based ultra-flexible self-leveling cement, specifically including the following raw materials by weight percentage: ordinary silicon cement 30%; aluminate cement 8.55%; gypsum 8%; heavy calcium carbonate 10%; washed and dried sand 22% %; rubber particles 20%; dispersible latex powder 1%; defoamer 0.08%; water reducer 0.1%; cellulose 0.06%; The washed and dried sand is 70 orders. The rubber particles are 50 mesh. During use, every 25 kilograms of the two-component cement-based super flexible self-leveling cement added 6.5L of acrylic acid emulsion with a solid content of 25% as a stirring liquid.

Embodiment 2

[0018] Two-component cement-based ultra-flexible self-leveling cement, specifically including the following raw materials by weight percentage: ordinary silicon cement 28.43%; aluminate cement 10%; gypsum 7.8%; heavy calcium carbonate 8.74%; washed and dried sand 18% %; rubber particles 25%; dispersible latex powder 1.5%; defoamer 0.12%; water reducer 0.18%; cellulose 0.09%; The washed and dried sand is 110 mesh. The rubber particles are 40 mesh. During use, every 25 kilograms of the two-component cement-based ultra-flexible self-leveling cement added 6.5L of acrylic acid emulsion with a solid content of 25% as a stirring liquid.

Embodiment 3

[0020] Two-component cement-based super flexible self-leveling cement, specifically including the following raw materials by weight percentage: ordinary silicon cement 28%; aluminate cement 9.2%; gypsum 6%; heavy calcium carbonate 10%; washed and dried sand 21% %; rubber particles 24.35%; dispersible latex powder 1%; defoamer 0.08%; water reducer 0.1%; cellulose 0.06%; The washed and dried sand is 70 orders. The rubber particles are 70 mesh. During use, every 25 kilograms of the two-component cement-based super flexible self-leveling cement added 6.5L of acrylic acid emulsion with a solid content of 25% as a stirring liquid.

[0021] The cement-based self-leveling mortar prepared in Example 3 was inspected (the inspection basis is JC / T 985-2017 "Cement-based self-leveling mortar for ground"), and the detection data were obtained as follows:

[0022]

[0023] It can be seen that the two-component cement-based ultra-flexible self-leveling cement of the present invention ful...

Abstract

The invention discloses double-component cement-based super-flexible self-leveling cement. The self-leveling cement specifically comprises the following raw materials in percentage by weight: 28%-30% of ordinary silicon cement, 8%-10% of aluminate cement, 5%-8% of gypsum, 8%-10% of ground calcium carbonate, 18%-22% of washed baked sand, 20%-25% of rubber particles, 1%-1.5% of dispersible latex powder, 0.08%-0.12% of a defoaming agent, 0.1%-0.18% of a water reducer, 0.06%-0.09% of cellulose, 0.04%-0.06% of an early strength agent and 0.1%-0.15% of a retarder. During use, 6.5 L of acrylic emulsion with a solid content of 25% is added into every 25 kilograms of the double-component cement-based super-flexible self-leveling cement as stirring liquid. Compared with existing self-leveling cement on the current market, the double-component cement-based super-flexible self-leveling cement has super-high flexibility and adhesion, hollowing and cracking of self-leveling cement can be effectively controlled, moreover, no floating ash exists on the surface of the double-component cement-based super-flexible self-leveling cement, adhesion of floor glue and the self-leveling cement can be improved, and the phenomenon of bumps, due to halfway floating ash treatment, of a PVC floor is prevented.

Description

technical field [0001] The invention belongs to the technical field of cement, in particular to two-component cement-based super-flexible self-leveling cement. Background technique [0002] Self-leveling cement is a high-tech environmental protection product with high technological content and complicated technical links. It is a dry-mixed powder material composed of a variety of active ingredients, which can be used after mixing with water on site. After a little spreading with a scraper, a high flat base surface can be obtained. The self-leveling cement hardens quickly, and people can walk on it after 4-5 hours. After 24 hours, the surface layer construction (such as wooden floor, diamond board, etc.) can be carried out. The construction is quick and easy, which is unmatched by traditional manual leveling. Its safety, pollution-free, beautiful, fast construction and put into use are the characteristics of self-leveling cement. However, cement-based self-leveling cement,...
