Detailed Description
The present invention is further described below, but the scope of the present invention is not limited to the following.
A coating for decorating and protecting bridge piers and bridges comprises water-based fluorine-containing acrylate resin, K2 silicone resin emulsion, NSR 801 paint film reinforcing agent, MK888 methyl potassium silicate aqueous solution, polyphosphate, material powder, HEC cellulose, auxiliary materials and water for supplementing.
The high-content water-based fluorine-containing acrylic resin is selected for two reasons: on one hand, because the surface energy of organic silicon molecules is low, and the chemical affinity of a Si-O-Si molecular chain is high, the organic silicon molecules can migrate to the surface of a coating film in the film forming process, so that the weather resistance of a building is greatly improved, part of micromolecular emulsion can permeate into concrete to form a three-dimensional cross-linked hydrophobic network structure, a permanent protective layer is formed on the surface of a material, the permeation of harmful ions is reduced, the corrosion of reinforcing steel bars is prevented, and the weather resistance and the corrosion resistance of the material are improved; on the other hand, the hydroxyl group contained in the inorganic silicate material has good affinity with the inorganic silicate material, so that the inorganic silicate material is firmly connected with the substrate. The nonpolar organic groups are arranged outwards to form a hydrophobic layer, so that the surface characteristics of the silicate material are changed, and a hydrophobic effect can be achieved.
Meanwhile, the water-based fluorine-containing acrylate resin is prepared from acrylic branched chain structure modified fluororesin, and because the fluorine-containing group is positioned on the side chain of the polymer and is oriented outwards, the fluorine-containing group in the polymer can be enriched to the interface between the polymer and air and can extend into the air in the film forming process, so that the fluorine-containing acrylate polymer has excellent surface performance. Because the bond length of the C-F bond is small, the bond energy is high, the polarizability is low, the coating is applied to decoration and protection of bridge piers and bridges, the bridge piers and the bridges have excellent weather resistance, thermal stability, chemical stability, water resistance, oil resistance, stain resistance and self-cleaning property, and the durability can reach more than 15 years.
The MK888 is a methyl potassium silicate aqueous solution, has the characteristics of permeability, absorbability and capability of keeping the natural appearance of the substrate, and generates polymethyl silicic acid by contact reaction with water; after the water is evaporated, methyl potassium silicate reacts with carbon dioxide (CO2) in the air to generate potassium carbonate K2CO 3. The polymethylsilicic acid and the potassium carbonate endow the surface layer of the base material with an insoluble reticular waterproof breathable film, and the waterproof film has excellent waterproof effect and seepage-proofing and moisture-proofing properties.
The NSR 801 paint film reinforcing agent is a modified inorganic silicic acid nano material, is a good inorganic adhesive and surface modifier, is applied to the paint in the scheme, and can improve the mechanical properties (hardness, adhesive force, tensile strength and the like) of a paint film on the surface of a bridge pier, so that after the bridge pier is coated with the paint in the scheme, the paint film on the surface of the bridge pier has better weather resistance, water resistance and water-white resistance and excellent paint film anti-after-tack property.
When the coating for decorating and protecting the bridge pier and the bridge is prepared, the steps are as follows:
s1, adding water into the stirring tank, adding the dispersing agent, the HEC cellulose, part of the defoaming agent and the powder together, rotating at a high speed, wherein the rotating speed is 1000-1200 r/min, and dispersing for 10-20 min;
s2, sequentially adding a preservative, a film-forming aid, an MK888 methyl potassium silicate aqueous solution, part of polyphosphate, a BS1306 hydrophobing agent and an NSR 801 paint film reinforcing agent, stirring and dispersing for 5-10 min, and reducing the rotating speed to 400-600 r/min;
and S3, finally, sequentially adding the water-based fluorine-containing acrylate resin, the K2 silicone resin emulsion, the residual polyphosphate and the residual defoaming agent, stirring and dispersing for 10-20 min, adding water during stirring, keeping the viscosity, and keeping the rotating speed at 400-600 r/min.
Three more preferred embodiments are used below.

The auxiliary materials comprise 0.1 part of dispersing agent, 0.8 part of BS1306 hydrophobic agent, 0.5 part of thickening agent, 0.10 part of film-forming additive, 0.10 part of preservative and 0.10 part of defoaming agent.
[ example 3 ]
A coating for decorating and protecting bridge piers and bridges comprises the following components in parts by weight: 20 parts of water-based fluorine-containing acrylate resin, 28 parts of K2 silicone resin emulsion, 6 parts of NSR 801 paint film reinforcing agent, 1.4 parts of MK888 potassium methyl silicate aqueous solution, 0.10 part of polyphosphate, 12 parts of material powder, 0.25 part of HEC cellulose and 2.0 parts of auxiliary material; also comprises water for supplementing.

Experiment one: the coating in this scheme of chooseing for use compares with ordinary pier coating, and key performance is as shown in table one.
Compared with the common bridge pier coating, the bridge pier coating has more excellent saltpetering alkali resistance, scrubbing resistance, stain resistance and water permeability resistance, and the artificial aging resistance is 1500h without abnormality, so that the bridge pier coating has excellent weather resistance and durability. And the comparison of pencil hardness and contact angle shows that the paint film of the coating in the scheme has very high hardness and is very hydrophobic.
Table one key performance comparison of this scheme coating and ordinary bridge pier coating
Experiment two: and (5) construction appearance effect.
The bridge pier coating in the scheme can be used for color mixing and patting, and can be made into various color effects according to different construction processes. And the common bridge pier coating can only achieve the natural color effect of the fair-faced concrete and can not be mixed with colors.
The effect is as follows: effect of bare concrete
The same as the construction process of common bridge pier coating, the bridge pier coating directly coated in the scheme can achieve the effect of protecting the fair-faced concrete in bridge piers with good pouring quality, flat and smooth surfaces, uniform color, no honeycomb pitted surfaces and no rusty spots. But the pier coating in the scheme has more excellent hydrophobicity, paint film hardness and weather resistance and durability (as shown in figure 1).
The second effect is that: color repair effect
The bridge pier coating in the scheme can be mixed with colors to be made into special color-correcting paint for bridge piers, and is aimed at bridge piers with large local surface color difference or difficult spot removal. The application of the common bridge pier coating cannot be realized, and the special bridge pier color-repairing paint in the scheme is selected for repairing, so that the color difference repairing effect can be achieved (as shown in figure 2).
The effect is three: patting effect
In the scheme, the pier coating can be made into a pier patting paint, a patting construction process is selected, and a pattern pier effect is patted, but the common pier coating cannot (as shown in figure 3).
The above examples only show some embodiments of the present invention, but should not be construed as limiting the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
