Description
[01] The disclosure relates to the technical field of coatings, and in particular, to a calcium carbonate based inorganic coating, a preparation method and an application method thereof.
[02] A large number of salt substances contained in a marine environment may severely corrode such marine engineering materials as steel structures and concretes, and marine corrosion occupies about 1/3 of the total corrosion. The marine concrete corrosion damage caused a loss of about 200 billion yuan in 2018.
[03] The anti-corrosive coating is uniformly coated on surfaces of a protected object to form a compact protection layer, so as to prevent environmental erosion medium from entering and thus protect the material against corrosion. Anti-corrosive coatings are mainly divided into organic coatings and inorganic coatings. The organic coatings may release part of components in production and application processes, which harm the environment and human body more or less, and they generally have poor high temperature resistance and poor aging resistance. For above problems, some silicate and phosphate inorganic coatings are developed successively. However, the above two inorganic coatings are usually required to be completely cured at high temperature, which brings adverse effect to the corrosion resistance of the protected layer and accordingly limits the application thereof. The silicate and phosphate inorganic coatings cured at room temperature are developed in recent years, but they have complex preparation processes and long curing time.
[04] In view of this, it is necessary to provide a calcium carbonate based inorganic coating, a preparation and an application method thereof to solve the technical problems that the inorganic coatings of the normal temperature curing system in the prior art have complex preparation processes and long curing time.
[05] For the first aspect, the disclosure provides a calcium carbonate based inorganic coating, comprising the following raw materials in parts by weight: 60-80 parts of a carbonization gelatinization material, 1.5-2 parts of a polycarboxylate water reducer, 5- 10 parts of an inorganic nanometer dispersant, 1.6-2.4 parts of a polymer emulsion, 1-
1.2 parts of a carbonization enhancer, 0.3-0.5 parts of a stabilizer and 24-28 parts of water.
[06] For the second aspect, the disclosure provides a preparation method of the calcium carbonate based inorganic coating, comprising the following steps:
[07] S1: preparing the polycarboxylate water reducer, the carbonization enhancer and water into a solution;
[08] S2: adding the inorganic nanometer dispersant, the stabilizer and the solution in the carbonization gelatinization material and stirring the mixture, and then adding the polymer emulsion and continuously stirring the mixture uniformly to obtain the calcium carbonate based inorganic coating.
[09] The preparation method of the calcium carbonate based inorganic coating provided by the second aspect of the disclosure is used for obtaining the calcium carbonate based inorganic coating provided by the first aspect of the disclosure.
[10] For the third aspect, the disclosure provides an application method of the calcium carbonate based inorganic coating, comprising the following steps:
[11] coating the calcium carbonate based inorganic coating provided by the first aspect of the disclosure on a substrate surface, and then forming a calcium carbonate based inorganic coating layer on the substrate surface through carbonization curing.
[12] Compared with the prior art, the disclosure has the following beneficial effects:
[13] The disclosure has a simple preparation method with low cost and short curing time, a few types of raw materials are required, and carbon dioxide can be cured in the preparation process, which accords with the green energy conservation and emission reduction concept in current society;
[14] The calcium carbonate based inorganic coating provided by the disclosure has aging resistance, corrosion resistance and excellent high temperature resistance, and can be used for the surface corrosion prevention of steel structures or steel reinforced concrete structures, etc. in such severe service environment as oceans.
[15] FIG. 1is a slurry rheology curve of a calcium carbonate based inorganic coating measured at 25°C after different standing time according to embodiment 1 of the disclosure.
[16] To make the objective, technical solutions and advantages of the disclosure clearer, the following will further describe the disclosure in detail with reference to accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the disclosure, rather than for limiting the disclosure.
[17] For the first aspect, the disclosure provides a calcium carbonate based inorganic coating, comprising the following raw materials in parts by weight: 60-80 parts of a carbonization gelatinization material, 1.5-2 parts of a polycarboxylate water reducer, 5- 10 parts of an inorganic nanometer dispersant, 1.6-2.4 parts of a polymer emulsion, 1-
1.2 parts of a carbonization enhancer, 0.3-0.5 parts of a stabilizer and 24-28 parts of water.
[18] According to the disclosure, the carbonization gelatinization material is one or more of y-dicalcium silicate, monocalcium silicate, tricalcium disilicate and steel slag; preferably, the carbonization gelatinization material is y-C2S. The carbonization gelatinization material with lower hydration activity and higher carbonization activity is used as a main component of the inorganic coating in the disclosure, so as to make the obtained inorganic coating rapidly form a high-strength coating layer through a carbonization process after being coated on a substrate surface. Moreover, various materials in the system of the disclosure have extremely low hydration activity, and cannot be hardened under the absence of carbon dioxide, which is beneficial for long- time storage.
[19] Further, the selected y-C:S 1s the powder with particle size distribution of 0.5- 100 um and apparent density of 2.8-3.0 g/cm’. More further, y-C2S is prepared by sintering calcareous and siliceous raw materials at high temperature. Therein, the calcareous raw material is calcium hydroxide, calcium carbonate or a raw material rich in calcium hydroxide and calcium carbonate (carbide slag, limestone powder, thiourea residues, cyanamide residues, etc.); the siliceous raw material is silicon dioxide or a raw material rich in silicon dioxide (quartzite powder, sandstones, quartz sand tailings, gold tailings, etc.); the calcareous raw material and the siliceous raw material are mixed according to the molar ratio of equivalent calcium oxide and silicon dioxide of 2: 1, stirred uniformly in water and dried, and then sintered at 1300-1400°C.
[20] The polycarboxylate water reducer is added in the disclosure to achieve the adsorption on particle surfaces, so as to prevent particle aggregation through the composition effect of charge mutual-exclusion and steric hindrance and thus improve the dispersion performance. Further, the water-reducing rate of the selected polycarboxylate water reducer is 25-35%.
[21] According to the disclosure, the inorganic nanometer dispersant is one or two of silica fume and nanometer calcium carbonate. The inorganic nanometer dispersant is added in the disclosure to improve slurry mobility and reduce water usage amount, so as to improve the fluency and overall strength of the coating layer. Further, the SiO: content of the selected silica fume is 90-98%, and the specific surface area is 20000-25000 m?/kg; the particle size of the selected nanometer calcium carbonate is 0.01-0.1 um.
[22] The polycarboxylate water reducer and inorganic nanometer dispersant are compounded in the disclosure to give full play to the synergy thereof, so as to control coating layer slurry viscosity and improve the comprehensive performance of the coating layer.
[23] According to the disclosure, the polymer emulsion is one or two of an epoxy resin modified styrene-acrylic emulsion and a styrene-acrylic emulsion. Further, the solid content of the polymer emulsion is 30-60%. The epoxy resin modified styrene- acrylic emulsion and styrene-acrylic emulsion are added as the polymer emulsion in the disclosure to reduce porosity and play a waterproof role, so as to further improve the overall corrosion resistance of the coating layer. But the addition amount thereof should be moderate, because a small addition amount may lead to poor corrosion resistance effect and a large addition amount may be adverse to carbonization and cause the poor comprehensive performance of the coating layer.
[24] According to the disclosure, the carbonization enhancer is one or two of polyvinyl alcohol and chitosan. The carbonization enhancer is added in the disclosure to improve the calcium ion dissolution of the carbonization gelatinization material in a carbonization process and improve the carbonization degree, so as to enhance the carbonization strength and improve the comprehensive performance of the coating layer. Further, the particle size of the chitosan is 100-130 meshes, the ash content is less than
0.5%, the water content is less than 0.5%, and the deacetylation degree is greater than
90%.
[25] According to the disclosure, the stabilizer is calcium oxide. The calcium oxide is added as the stabilizer in the disclosure to false set the slurry and prevent slurry sedimentation, so that the slurry can recover viscosity by a smaller shearing force after long-time storage, which is conducive to long-time storage.
[26] For the second aspect, the disclosure provides a preparation method of the calcium carbonate based inorganic coating, comprising the following steps:
[27] SI: preparing the polycarboxylate water reducer, the carbonization enhancer and water into a solution;
[28] S2: adding the inorganic nanometer dispersant, the stabilizer and the solution in the carbonization gelatinization material and stirring the mixture, and then adding the polymer emulsion and continuously stirring the mixture uniformly to obtain the calcium carbonate based inorganic coating.
[29] The preparation method of the calcium carbonate based inorganic coating provided by the second aspect of the disclosure is used for obtaining the calcium carbonate based inorganic coating provided by the first aspect of the disclosure.
[30] In the disclosure, the adding sequence of various components is required to be strictly controlled to avoid the poor slurry dispersion effect caused by direct material mixing and the influence on the performance of the coating layer.
[BI] According to the disclosure, for the two stirring operations in step S2, the stirring speed is 100-150 r/min, and the stirring time is 30-60 s. Under this condition, the solid particles can be fully dispersed and thoroughly mixed with the liquid.
[32] For the third aspect, the disclosure provides an application method of the calcium carbonate based inorganic coating, comprising the following steps: |33] coating the calcium carbonate based inorganic coating provided by the first aspect of the disclosure on a substrate surface, and then forming a calcium carbonate based inorganic coating layer on the substrate surface through carbonization curing.
[34] According to the disclosure, the coating process can be performed by spray- coating, dip-coating and brush-coating methods, preferably a high pressure jetting method.
[35] According to the disclosure, the carbonization curing conditions are as follows: the carbonization temperature is 5-40°C, the relative humidity 1s 10-60%, the volume concentration of carbon dioxide is 70-99.8%, the gas pressure is 0.2-0.4 MPa, and the curing time is 6-12 h.
