Embodiment 1

[0023] A method for preparing additives for self-leveling cushion mortar and wear-resistant floor mortar, characterized in that: the preparation method has the following steps:

[0024] (1) Prepare the following materials according to the mass-to-weight ratio, emulsion: 80; preservative: 0.3; reinforcing agent: 5; defoamer: 0.5; water reducing agent: 5; 1.5; water: 6.5;

[0025] (2) Add emulsion, anti-sedimentation agent, hydrophobic agent, water reducer, reinforcing agent and defoamer to the reaction kettle for blending, raise the temperature to 80°C, stir at a constant speed for 30 minutes, and then cool the mixture to room temperature;

[0026] (3) Add preservative and fiber to the above-mentioned cooled mixed solution, and stir at a constant speed at room temperature for 10-20 minutes to obtain a solid-liquid suspension additive product.

[0027] When the additive of the present invention is actually implemented, the ratio of each component is as follows in terms of weigh...

Embodiment 2

[0029] A method for preparing additives for self-leveling cushion mortar and wear-resistant floor mortar, characterized in that: the preparation method has the following steps:

[0030] (1) Prepare the following materials according to the mass-to-weight ratio, emulsion: 80; preservative: 0.3; reinforcing agent: 4; defoamer: 0.5; water reducing agent: 5; 1.5; water: 7.2; other steps are the same as in Example 1, and the formulation of the additive is the same as in Example 1 when actually implemented.

Embodiment 3

[0032] A method for preparing additives for self-leveling cushion mortar and wear-resistant floor mortar, characterized in that: the preparation method has the following steps:

[0033] (1) Prepare the following materials according to the mass-to-weight ratio, emulsion: 80; preservative: 0.3; reinforcing agent: 3; defoamer: 0.5; water reducing agent: 5; 1.5; water: 8.5; other steps are the same as in Example 1, and the formulation of the additive is the same as in Example 1 when actually implemented.

[0034] The performance test data of each phase after the additive of embodiment one to three gained is applied to mortar setting is as follows:

[0035]

[0036] The relevant performance data after the mortar is set shows that the flexural and compressive properties of the mortar are significantly improved after the addition of additives, and the 28d flexural resistance is increased from 16% to 61%, and the compressive resistance is increased from 10% to 65%. The anti-incorp...

Abstract

The invention relates to the technical field of concrete additives and specifically relates to an additive for self-leveling bedding mortar and wear-resistant floor mortar and a preparation method thereof. The additive comprises the following components in parts by weight: 60-80 parts of emulsion, 0-1 part of preservative, 1-20 parts of strengthening agent, 0-1 part of defoaming agent, 5-10 parts of water reducer, 1-2 parts of hydrophobic agent, 0-2 parts of anti-settling agent, 1-2 parts of fiber and 10-20 parts of water. By blending the additive disclosed by the invention during construction, the mortar has better flowability, and cement can always get appropriate water during hydration, so that the cement can be fully hydrated during various stages, and the mortar has higher strength after condensation. The preparation method disclosed by the invention is simpler and lower in cost, and suitable for popularization and use in large-scale supermarkets, shopping malls, parking lots, stadiums, factory workshops, warehouses and other large-area terraces.

Description

technical field [0001] The invention relates to the technical field of concrete additives, in particular to an additive for self-leveling cushion mortar and wear-resistant ground mortar and a preparation method thereof. Background technique [0002] The National Twelfth Five-Year Plan includes my country's urbanization as a development goal, and clearly requires that the national urbanization rate reach 60% by 2020, which means that my country will enter a period of rapid urbanization development. With the vigorous development of various infrastructure constructions, various wear-resistant and crack-resistant floors and self-leveling floors are increasingly used. The self-leveling mortar system is the most technically demanding and complex mortar in the mortar system. The self-leveling cushion mortar is an important guarantee for the self-leveling effect of the surface layer. Therefore, ensuring the self-leveling of the mortar and the stability of various performances is the...
