Embodiment 1
[0028] Formula: 1% potassium silicate with a modulus of 5, 0.01% polyethylene oxide, 0.5% octyltriethoxysilane, 0.5% lignosulfonate surfactant, 0.3% polyvinyl acetate emulsion, and the balance is water.
[0029] Preparation method: Mix the components in the above formula evenly according to the above mass percentages, and stir to prepare the concrete curing agent.
[0030] Application: 1) Polish the concrete floor with 50-mesh and 300-mesh sand mills, and clean the floor;
[0031] 2) Dilute the curing agent of the present invention by 1 to 2 times and brush the concrete floor;
[0032] 3) After the concrete floor is dry, polish it with 500-mesh and 1000-mesh polishing machines respectively to obtain a concrete floor with high hardness and high gloss.
Embodiment 2
[0034] Formula: Potassium silicate with a modulus of 5.5 30%, polyethylene oxide 0.5%, octyltriethoxysilane 0.5%, octyltriethoxysilane aqueous emulsion 1%, naphthalenesulfonate 1%, butylbenzene Emulsion 1%, balance water.
[0035] The preparation method and application method of the concrete curing agent are the same as in Example 1.

Abstract
The invention discloses a concrete curing agent. The concrete curing agent comprises the following materials in percentage by weight: 1%-30% of potassium silicate, 0.01%-0.5% of penetrating agent, 0.5%-1.5% of water repellent, 0.5%-1% of surface active agent, 0.3%-1% of surface modifying agent and the balance of water, wherein the modulus of the potassium silicate is more than 5. The invention also provides a preparation method of the concrete curing agent. The preparation method comprises the following steps of: uniformly mixing the components in the formula according to the mass percentage, stirring and obtaining the concrete curing agent. The invention also provide a construction method of the concrete curing agent. The construction method comprises the following steps of: polishing concrete floors, brushing the concrete floors with the curing agent, and then polishing. The concrete curing agent disclosed by the invention has the advantages that due to addition of the high-modulus potassium silicate, silicate ions in the curing agent reacts with unreacted free ions in concrete to generate a complex, and then the complex is filled in capillary pores in concrete, so that the blocking for fine pores of concrete structures, the effects of sealing and curing are achieved, the strength and the hardness of the concrete are improved to a greater extent, and the sanding of the concrete is prevented.
Description
technical field [0001] The invention relates to a curing agent and its preparation method and application, in particular to a concrete curing agent and its preparation method and application. Background technique [0002] Concrete is composed of coarse granular aggregates and cement hydrates. In the process of concrete construction, the cement components and water undergo a very complex chemical reaction to form hard hydrates, which bind the aggregates filled together to form A structure with high compressive strength, and has the advantages of economy, durability, fire resistance, and high compressive performance. However, due to the inherent process of cement hardening, concrete has unavoidable disadvantages, that is, the microstructure contains a large number of interpenetrating capillary pores, which leads to the occurrence of ash and sand, which seriously affects the corporate image, product quality, equipment service life, The physical and mental health of our employe...
