Description

A method for protecting the surface of fair-faced concrete

technical field

The invention relates to the field of civil engineering, in particular to a method for protecting the surface of fair-faced concrete.

Background technique

Existing prefabricated fair-faced concrete components, when the prefabricated finished products are stored off-site, they are easily polluted by wind and rain, which affects the appearance quality of the prefabricated products; similarly, after the prefabricated fair-faced concrete components are installed, the finished products are more likely to be polluted, which affects the overall appearance quality . Traditionally, paint is sprayed on the finished surface of prefabricated fair-faced concrete components. During the drying process of the paint, the coating will produce air bubbles or holes, which will easily cause pollution during later use. The oil-based protective agent has general permeability, contains harmful substances, and is not resistant to solvent wiping.

Contents of the invention

The purpose of the present invention is to overcome the problems in the prior art that the finished surface of the prefabricated fair-faced concrete component is sprayed with paint. During the drying process of the paint, the coating will produce air bubbles or holes, which will easily cause pollution when used later, and the oily protective agent has a general permeability. , and contains harmful substances, and is not resistant to solvent wiping, and provides a method for protecting the surface of clear-water concrete.

In order to realize the above-mentioned purpose of the invention, the present invention provides the following technical solutions:

A method for protecting the surface of clear water concrete, comprising the following steps:

A. The clear water concrete is cured and the surface color is evenly hydrated;

B, the surface of the clear water concrete is sprayed with silane, and the silane is uniformly sprayed in a mist form;

C. The fair-water concrete is left to air-dry, and the silane forms a protective film on the surface of the fair-water concrete.

Using the method for protecting the surface of clear-water concrete according to the present invention, the sprayed silane forms a protective film on the surface of the clear-water concrete. The surface of the protective film has uniform color and no air bubbles and holes, and has solvent wiping resistance, water resistance, and water resistance. Alkaline, anti-adhesive, anti-aging, strong repairability, the method is simple, easy to operate, and the effect is remarkable.

Preferably, the silane is a fluorine series silane.

Using fluorine series silane, the clear-water concrete forms a protective film on the surface, which is easy to clean, anti-pollution, retains the original color of concrete, and has no film-forming traces, pinholes, and sags.

Preferably, before performing the step B, the surface of the fair-faced concrete is cleaned.

Preferably, before performing the step B, extract the silane stock solution and dilute it with pure water at a ratio of 1:3-4 for preparation.

Preferably, when performing the step B, the silane is sprayed through an air compressor spray gun.

Preferably, the spray gun is 20cm-40cm away from the surface of the fair-faced concrete when spraying.

In summary, owing to adopting above-mentioned technical scheme, the beneficial effect of the present invention is:

1. Using the method for protecting the surface of clear-water concrete according to the present invention, the sprayed silane forms a protective film on the surface of the clear-water concrete. The surface of the protective film has uniform color, no air bubbles and holes, and has solvent wiping resistance and water resistance. , Alkali resistance, anti-adhesive, anti-aging, strong repairability, the method is simple, easy to operate, and the effect is remarkable;

2. Using the method for protecting the surface of clear-water concrete according to the present invention, using fluorine series silanes, the surface of clear-water concrete forms a protective film that is easy to clean, anti-pollution, retains the original color of concrete, and has no film-forming traces, pinholes, or sags.

Description of drawings

Fig. 1 is a schematic flow chart of the method for protecting the surface of fair-faced concrete according to the present invention.

detailed description

The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

Example

As shown in Figure 1, a kind of clear water concrete surface protection method of the present invention comprises the following steps:

A. The clear water concrete is cured and the surface color is evenly hydrated;

B. Clean the surface of the clear water concrete, extract the fluorine series silane stock solution and dilute it with pure water in a ratio of 1:3-4;

B. Spraying the fluorine series silane on the surface of the clear water concrete through an air compressor spray gun, the spray gun is 30 cm away from the surface of the clear water concrete when spraying, and the fluorine series silane is uniformly sprayed in a mist form;

C. The fair-water concrete is allowed to stand for 48 hours to air-dry, and the fluorine series silane forms a protective film on the surface of the clear-water concrete.

Using the method for protecting the surface of clear-water concrete according to the present invention, the sprayed fluorine series silane forms a protective film on the surface of the clear-water concrete. The surface of the protective film has uniform color, no air bubbles and holes, and has solvent wiping resistance and water resistance. , Alkali resistance, anti-adhesive, anti-aging, strong repairability, using fluorine series silane, the surface of the fair-faced concrete forms a protective film that is easy to clean, anti-pollution, retains the original color of the concrete, has no film-forming traces, pinholes, Hanging, the method has simple steps, convenient operation and remarkable effect.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
