Problems solved by technology

The technical key of ready-mixed mortar is the high-performance mortar admixture, and the use of traditional mortar water reducer will cause the mortar to lose too much consistency within a certain period of time, making it difficult for the mortar to go on the wall, or to sag after it is put on the wall. , can no longer meet the construction requirements of ready-mixed mortar

Embodiment 1

[0009] A wet-mix mortar admixture, the mortar admixture includes a plasticizer and a coagulant, wherein the plasticizer is composed of the following components: 5% of polycarboxylate water reducing agent, 0.5% of starch ether, two Ethanol monoisopropanolamine 0.5%, polyethylene glycol 0.1%, thixotropic lubricant 0.5%, cosolvent 0.2%, and the rest are water; the coagulant is composed of the following components: sodium gluconate 5%, Plasticizer 0.2%, stabilizer 1%, and the rest is water. The dosage of plasticizer is 3%, and the dosage of coagulant is 1%.

[0010] Preparation of the product: The plasticizer and the coagulant are dissolved in cold water by the above various materials and stirred evenly. In actual use, the plasticizer and the coagulant of the present invention are both aqueous products, and two sets of metering systems are used to separate them. mixed.

Embodiment 2

[0012] The plasticizer is composed of the following components: polycarboxylate water reducer 10%, starch ether 1%, diethanol monoisopropanolamine 1%, polyethylene glycol 0.2%, thixotropic lubricant 1.5% , cosolvent 0.3%, the rest is water; the coagulant is composed of the following components: sodium gluconate 10%, plasticizer 0.5%, stabilizer 1%, and the rest is water. When used, the dosage of plasticizer is 2% of the amount of glue material, and the dosage of coagulant is 0.6%.

[0013] The preparation method is the same as that of Example 1.

Embodiment 3

[0015] The plasticizer is composed of the following components: polycarboxylate water reducer 15%, starch ether 2%, diethanol monoisopropanolamine 1.5%, polyethylene glycol 0.4%, thixotropic lubricant 2% , cosolvent 0.4%, the rest is water; the coagulant is composed of the following components: sodium gluconate 15%, plasticizer 1%, stabilizer 2%, and the rest is water. When in use, the dosage of plasticizer is 1.5%, and the dosage of coagulant is 0.3%.

[0016] The preparation method is the same as that of Example 1.

Abstract

The invention discloses a wet-mixed mortar admixture. The wet-mixed mortar admixture comprises a plastic regulating agent and a coagulation regulating agent, wherein the plastic regulating agent is prepared from components as follows: 5%-15% of a water reducer, 0.5%-2% of a water retaining agent, 0.5%-1.5% of an additive, 0.1%-0.6% of a shrinkage reducing agent, 0.5%-3% of a thixotropic lubricant, 0.2%-0.4% of a cosolvent and the balance of water; the coagulation regulating agent is prepared from components as follows: 5%-15% of a retarder, 0.2%-2% of a plastic retaining agent, 1%-3% of a stabilizer and the balance of water. The wet-mixed mortar admixture comprises the plastic regulating agent and the coagulation regulating agent, mortar has good plastic retaining property and workability due to mixing of the double components, the opening time is greatly prolonged, and the compressive strength and the adhesion stress of the mortar are improved.

Description

technical field [0001] The invention relates to the technical field of mortar admixtures, in particular to a wet-mixed mortar admixture. The invention introduces a plastic-preserving component, a thixotropic lubricating component, a retarding component and a reinforcing component on the basis of a water reducing agent. , shrinkage-reducing components and stable components, so that the mortar has good plasticity and time delay, and also solves the problem of hollowing and cracking after the mortar is placed on the wall. Background technique [0002] As the state advocates "energy saving and emission reduction", building a conservation-oriented society and realizing the strategic requirements of sustainable development, it is of great significance to popularize and apply ready-mixed mortar, especially wet-mixed mortar. The technical key of ready-mixed mortar is high-performance mortar admixture, and the use of traditional mortar water reducer will cause the mortar to lose too ...
