Problems solved by technology

Among them, the anti-seepage effect of chloride salts is very good, but chloride ions corrode steel bars and reduce the service life of buildings
The anti-seepage effect of stearates and silicone-based waterproofing agents is poor, and the anti-seepage requirements cannot be met
Silicone waterproofing agent has the advantages of strong penetration ability and good hydrophobicity, but poor impermeability

Abstract

The invention relates to the technical field of concrete protective agents for buildings and in particular discloses a capillary crystalline waterproofing agent and a preparation method of the capillary crystalline waterproofing agent. The capillary crystalline waterproofing agent consists of an organic silicon waterproofing agent, an amorphous silicon dioxide colloidal solution, a surfactant, barium hydroxide and water. The preparation method comprises the following steps: sequentially adding the water, organic silicon waterproofing agent, the amorphous silicon dioxide colloidal solution, the surfactant and the barium hydroxide into a reaction kettle, heating to a reaction temperature, stirring, reducing the temperature to room temperature, filtering to remove impurities, and obtaining the capillary crystalline waterproofing agent. The capillary crystalline waterproofing agent is an organic and inorganic combination, is colorless transparent liquid, has the characteristics of high infiltration capacity, high hydrophobicity, low water absorption rate, environment friendliness and harmlessness and can penetrate into concrete pores to form lots of insoluble crystals to block the concrete pores, the intrusion of sulfate to the concrete can be reduced, and a waterproof protective effect is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete protective agents for buildings, in particular to a osmotic crystalline waterproofing agent and a preparation method thereof. Background technique [0002] Concrete is a porous composite material, which contains a large number of pores and microcracks. Some aggressive media (such as chloride salts, sulfates, etc.) will enter the interior of the concrete with these defects under the action of water, and these substances will corrode to Steel bars seriously affect the durability and life of concrete structures. [0003] The focus of concrete protection is waterproof performance, which is mainly divided into flexible waterproof and rigid waterproof. Flexible waterproofing refers to the outsourcing and waterproofing of structures with waterproof membranes or waterproof coatings, so as to realize the waterproofing of buildings. Rigid waterproof refers to relying on the waterproofing of the concrete ...
