Problems solved by technology

However, the impermeability performance is limited. It is necessary to combine the activated barium ions in the concrete with the sulfate ions infiltrated from the outside of the concrete to form an inert and stable barite, so as to better exert its impermeability and corrosion resistance. It cannot solve the problems of cement concrete and its prefabricated efflorescence, and the capillary pores on the surface are easily stained by pollutants.

preparation example 1

[0041] Mix and stir 3kg of fluorocarbon resin, 0.02kg of wetting and dispersing agent, and 1kg of solvent evenly, then add 3.6kg of pigment, disperse and stir evenly, and grind until the fineness is less than 25 microns to obtain pigment slurry. Mix and stir the pigment slurry with 10kg of fluorocarbon resin, add 0.02kg of defoamer and 0.02kg of leveling agent during the stirring process, add 1kg of solvent after stirring evenly, and set aside the mixed material after stirring; weigh 1kg of curing agent is added to the above-mentioned uniformly stirred mixture before use, and it can be stirred evenly. The fluorocarbon resin used in this preparation example is LF-200, the wetting and dispersing agent is BYK-163, the solvent is dimethyl carbonate, the pigment is carbon black, the defoamer is BYK-065, and the leveling agent is BYK-330. The curing agent adopts TKA-75.

preparation example 2

[0043] Mix and stir 2kg of fluorocarbon resin, 0.1kg of wetting and dispersing agent, and 1kg of solvent evenly, then add 2.7kg of pigment, disperse and stir evenly, and grind to a fineness of less than 25 microns to obtain a pigment slurry. Mix and stir the pigment slurry with 6kg of fluorocarbon resin, add 0.05kg of defoamer and 0.15kg of leveling agent during the stirring process, add 1.5kg of solvent after stirring evenly, and set aside after stirring; Take 0.8kg of curing agent, add it to the above-mentioned uniformly stirred mixture before use, and stir evenly. The fluorocarbon resin used in this preparation example is GK-570, the wetting and dispersing agent is BYK-2001, the solvent is ethyl acetate, the pigment is carbon black, the defoamer is BYK-066N, and the leveling agent is BYK-358.

Abstract

The invention relates to a concrete product capable of being solidified at room temperature and a preparation method and application thereof, and belongs to the technical field of concrete materials.The concrete product capable of being solidified at room temperature comprises base-layer concrete and a surface layer, wherein the surface layer comprises a mortar layer and a protection layer, and the mortar layer is located between the base-layer concrete and the protection layer; the base-layer concrete is cement concrete, the mortar layer prepared from cement mortar, and the protection layeris prepared from FEVE fluorocarbon coating. The concrete product has the advantages of being resistant to contamination, easy to clean, stable in structure and durable in protection effect, and whiskering is never generated.

Description

technical field [0001] The invention relates to the technical field of concrete materials, more specifically, it relates to a normal-temperature-cured concrete product and its preparation method and application. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. The more commonly used concrete is made of cement as cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and mixed. The resulting cement concrete is widely used in civil engineering. Concrete materials can be prepared and used at the construction site, and can also be made into prefabricated products and transported to the construction site for laying or installation. At present, there are mainly two ways to prepare cement concrete and its pre-products: one is formed by mechanical pressing, and the surface density is poor; There are many capillary pores on...
