Description
Technical Field
The invention belongs to the technical field of pavement maintenance materials, and particularly relates to a surface treatment material for a concrete structure and a preparation method thereof.
Background
With the increase of social demands of concrete structures, the problems of stability and durability of the concrete structures are more and more emphasized. With the rapid increase of national economy, social infrastructure is gradually completed, and the number of civil buildings is greatly increased. The safety of the building structure has become a social problem due to the gradual aging of various external and internal factors, and the safety of the building structure is urgently needed to be solved. However, demolition reconstruction is not only costly, but also causes many social problems.
Especially for commemorative buildings and particularly important building designs (such as the three gorges dam), the aging can not be used continuously, the reconstruction cost is very large, and a plurality of social problems are caused, so that the durability is improved by periodically patrolling, finding dangerous points in time and repairing the dangerous points. The concrete surface treatment materials in the prior art mainly use organic solvents such as toluene, so that the problem that volatile substances and formaldehyde contained in the organic solvents have adverse effects on the environment exists. At the same time, the durability and corrosion resistance and adhesion are not as expected. Therefore, it is urgently needed to develop a surface treatment material with high durability and environmental protection for a concrete structure, and prolong the service life of a building structure.
Disclosure of Invention
In view of the above, the present invention provides a polymer concrete protective coating material and a preparation method thereof, aiming to overcome the defects in the prior art, so as to solve the technical problems of poor durability and serious pollution of the concrete surface treatment material in the prior art.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a polymer concrete protective coating material is prepared by mixing an aqueous solution and a mixture;
the aqueous solution comprises 60-70 parts by weight of aqueous acrylic resin emulsion, 5-10 parts by weight of aqueous MMA resin emulsion, 5-10 parts by weight of aqueous polyurea, 2-3 parts by weight of alkoxy silane, 3-5 parts by weight of potassium silicate and 2-3 parts by weight of silicate;
the mixture comprises 10-15 parts by weight of titanium dioxide, 3-5 parts by weight of silicon powder, 5-9 parts by weight of diatomite, 0.3-0.5 part by weight of defoaming agent, 0.3-0.5 part by weight of dispersing agent and 1-2 parts by weight of thickening agent.
The aqueous acrylic resin emulsion comprises an acrylic resin emulsion, an acrylic resin aqueous dispersion (also called water-dilutable acrylic acid) and an acrylic resin aqueous solution. The emulsion is synthesized by emulsifying oily vinyl monomers in water under the initiation of an aqueous radical initiator, and the resin aqueous dispersion is synthesized by different processes such as radical solution polymerization or stepwise solution polymerization. From the particle size of the particles: emulsion particle size > particle size of aqueous resin dispersion > particle size of aqueous solution. The water-soluble acrylic resin is anionic, and its copolymerized resin monomer is made up by using proper quantity of unsaturated carboxylic acid, such as acrylic acid, methacrylic acid, maleic anhydride and itaconic acid, etc. to make side chain have carboxyl group, then using organic amine or ammonia water to neutralize and salt so as to obtain the water-solubility. In addition, the water solubility of the resin can be increased by selecting proper monomers to introduce hydrophilic groups such as-OH hydroxyl, -CONH2 amido or-O-ether bond on the side chain of the acrylic resin. The carboxyl is hydrophilic group and can form hydrogen bond with water, so that the lower carboxylic acid can be mutually dissolved with water in any ratio; the acrylic resin neutralized into salt can be dissolved in water, but the water solubility is not very strong, and an opaque liquid or a solution with very high viscosity is often formed, so a certain proportion of hydrophilic cosolvent must be added into the water-soluble resin to increase the water solubility of the resin. The hydrophilic cosolvent is ethylene glycol monobutyl ether, which can improve the emulsifying property and an auxiliary solvent for dissolving mineral oil in the soap solution, and is an acrylic resin, an organic synthetic resin intermediate and the like. After the waterborne MMA resin emulsion is added with the waterborne acrylic resin, the toughness of the polymer resin is improved, and the tensile property is obviously improved.
Dissolving MMA resin in proportion, dewatering, filtering to remove impurities, keeping the pH close to 7, and keeping the temperature at 200 ℃ for later use; adding an emulsifier into water according to the proportion of 1: 0.05 of MMA resin, adding the emulsifier into the MMA resin in an oil-in-water type (O/W type, namely hydrophilic type), stirring at the rotation speed of 70-90 revolutions per minute, uniformly stirring, and filtering to obtain emulsified aqueous MMA resin emulsion; the emulsifier can adsorb MMA resin and water interface, so as to reduce the free energy of MMA resin and water interface obviously and form homogeneous stable emulsion. The principle of action is that during the emulsification process, the dispersed phase is dispersed in the form of droplets (micron-sized) in the continuous phase, and the emulsifier reduces the interfacial tension of the components in the mixed system and forms a firmer film on the surface of the droplets or forms an electric double layer on the surface of the droplets due to the electric charge given by the emulsifier, thus preventing the droplets from aggregating with each other and maintaining a uniform emulsion. The aqueous MMA resin emulsion has the advantages of short curing time, strong bonding force, outstanding compressive and flexural strength, bonding strength of 2.5MPa, compressive strength of 38MPa and flexural strength of more than 4MPa, is remarkably improved compared with the traditional protective coating material, and provides the characteristics of good durability, fast open traffic and the like.
The emulsifier is a condensate of isomeric alcohol and ethylene oxide, can be dispersed or dissolved in water with resin, and has excellent wettability and permeability. A small amount of the product is added into the pretreatment formula, so that an excellent water-soluble effect can be obtained. The emulsion has a special emulsifying effect on MMA resin (methyl methacrylate), can improve the efficacy after use, has less dosage than common silicone oil emulsifier, is more stable, has extremely strong permeability, and can permeate into the interior of a building structure, thereby improving the use performance.
The water-based polyurea is an oligomer with amino as a main cross-linking gene and is compounded by using a non-ionic hydrophilic technology. The aqueous polyurea film is tough and wear-resistant, has high gloss and is insensitive to temperature, and the aqueous polyurea is prepared by field construction of semi-prepolymer, amine-terminated polyether, amine chain extender and other raw materials. The paint has extremely strong hydrophobicity, is insensitive to the environmental humidity, can be sprayed on water (or ice) to form a film, can be normally constructed under extremely severe environmental conditions, and has particularly prominent performance. The coating added with the water-based polyurea has more flexibility, sufficient rigidity, rich colors, compactness, continuity and no seam, completely isolates the permeation of moisture and oxygen in the air, and has incomparable anti-corrosion and protective properties. It has multiple functions of wear resistance, water resistance, shock resistance, fatigue resistance, aging resistance, high temperature resistance, nuclear radiation resistance and the like.
Preferably, the alkoxysilane is methoxysilane. The alkoxysilane reacts with water to give off the corresponding aliphatic alcohol and forms the corresponding condensate with the other resin.
The potassium silicate is used as an accelerating agent in concrete admixtures. The potassium silicate is colorless or yellowish translucent to transparent glass, has hygroscopicity, and has strong alkaline reaction. Slowly soluble in cold water and also used as a coating layer filler. In a stable state, the product is a viscous liquid of hyaluronic acid, is blue-green, is easily dissolved in water and acid, and can separate out colloidal silicic acid, and the higher the potassium content is, the more easily the product is dissolved. The potassium silicate is added into the polymer concrete protective coating material, so that the material has stronger moisture absorption performance, is not easy to fall off in the later period, and has better alkali resistance and water compatibility.
The silicate minerals are characterized by regular tetrahedron structures, and the regular tetrahedrons are connected in a chain, double-chain, sheet or three-dimensional frame mode, so that the material has the characteristics of high compressive strength, high hardness, high temperature resistance and corrosion resistance. The silicate has a crystal structure with a more prominent anisotropy than island-shaped and ring-shaped silicate because the silicon oxygen skeleton is an extended chain and is distributed in parallel. In physical properties, cleavage develops in a direction parallel to the chain, the refractive index is higher in a direction parallel to or close to the chain, the direction perpendicular to the chain is lower, the birefringence is larger than that of island-shaped or ring-shaped minerals, most of the island-shaped or ring-shaped minerals have high melting points and stable chemical properties, and the island-shaped or ring-shaped minerals are added into the polymer concrete protective coating material to enable the minerals to be in an elongated form, often in columnar, needle-shaped and fibrous shapes, so that the material is more compact, high in strength and flexible.
The dispersant is a surfactant which has two opposite properties of lipophilicity and hydrophilcity in a molecule. The present invention utilizes a hydrophilic dispersion of sodium polyacrylate which uniformly disperses solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquids, while also preventing settling and agglomeration of the particles to form the amphiphilic agent required to stabilize the suspension. Various powders are reasonably dispersed in a solvent, and various solids are stably suspended in the solvent (or dispersion liquid) by a certain charge repulsion principle or a high molecular steric effect.
The thickening agent adopts an LD-7002 type aqueous leveling thickening agent with unsaturated antelope acid, is mainly used for improving the viscosity or consistency of a product, has the characteristics of small dosage, obvious thickening, convenient use and the like, a system using the unsaturated antelope acid as the thickening agent is generally a surfactant aqueous solution system, the surfactant forms micelles in an aqueous solution, the existence of electrolyte increases the association number of the micelles, the spherical micelles are converted into rod-shaped micelles, the movement resistance is increased, and the viscosity of the system is increased. However, when the electrolyte is excessive, the micelle structure is affected, the movement resistance is reduced, and the viscosity of the system is reduced. Therefore, the adding amount of the electrolyte is 1 to 2 percent by mass, and the electrolyte and other types of thickening agents act together to ensure that the system is more stable.
Another objective of the present invention is to provide a method for preparing the surface treatment material, comprising the following steps:
s1: preparation of MMA resin emulsion: dissolving MMA resin, removing water and impurities, adjusting pH to 7, and keeping at 200 deg.C; mixing and stirring MMA resin, an emulsifier and water at the stirring speed of 70-90 revolutions per minute, and filtering after uniform stirring to obtain emulsified aqueous MMA resin emulsion;
s2: pouring acrylic emulsion and water-based polyurea into the water-based MMA resin emulsion, and stirring at medium speed for 20 minutes to further obtain mixed liquid to form high polymer mixed liquid;
s3: pouring the alkoxy silane, the potassium silicate and the silicate into the mixed solution in the last step, and uniformly stirring for 10 minutes to obtain a polymer aqueous solution;
s4: sequentially adding titanium dioxide, silicon powder, diatomite, a defoaming agent, a dispersing agent and a thickening agent into the polymer aqueous solution in the last step, stirring at a low speed when filling, stirring at a medium speed for 25 minutes after the materials are put into the solution, and stirring at a low speed for 10 minutes to further obtain the polymer concrete protective coating material.
The polymer concrete protective coating material is applied to the construction of concrete, and the concrete construction steps are as follows:
a) in a concrete surface cleaning operation, various impurities on the surface of a building, such as dust, dirt, oil, rust, stains, and other oily products, are cleaned using a special cleaner or a weak acid cleaner, and the contaminants are removed again using a high pressure washer.
b) Coating an interface strengthening adhesive on the surface of the cleaned concrete to prevent the surface from dusting, and forming a working surface after drying;
c) coating a polymer concrete protective coating material on the working surface of the concrete to form a protective coating;
d) after 2 hours of curing period, the enclosure is removed, and finally the polymer concrete protective coating is formed.
The invention principle is as follows:
after adding the aqueous acrylic resin emulsion, the aqueous MMA resin emulsion and the aqueous polyurea material, synthesizing acrylic resin, MMA resin and polyurea water dispersion by a solution polymerization method, wherein a solvent is mutually soluble with water; in addition, monomers containing either dance-or tertiary amine groups, the former neutralized with base to give salt groups and the latter neutralized with acid to give quaternary amine salt groups, are formulated in the monomer formulation, and then water is added with vigorous stirring to give anionic and cationic dispersions, respectively. After the emulsion of the polymer is obtained through emulsification reaction, the emulsion is rapidly solidified into a tough reticular polymer structure through chemical crosslinking reaction to form a permanent elastic surface texture structure, and then the structure is synthesized with alkoxysilane, potassium silicate, titanium dioxide, silicon powder, diatomite, a defoaming agent, a dispersing agent and a thickening agent inorganic substance to prepare a polymer or copolymer combined reactant, a monomer with low molecular weight is converted into a polymer with high molecular weight through polymerization reaction, and the polymer or copolymer combined reactant reacts to form a plurality of molecules and is mutually bonded and crosslinked into relatively stable molecules (body type molecules) with a network structure. The suspension polymerization reaction converts linear or slightly branched macromolecules into a three-dimensional network structure, and the excellent performance is obviously improved after the suspension polymerization reaction and polyurea polymerization reaction. The conversion rate of the polymer is greatly improved in the chain polymerization reaction due to the relation between the average polymerization degree and the conversion rate after the aqueous MMA (methyl methacrylate), the aqueous acrylic acid and the polyurea material are simultaneously added, and in the step-by-step polymerization reaction, the conversion rate reaches 98 percent to form a mixed chain high polymer, finally form the polymer concrete protective coating material, and the characteristics of impact strength, flexibility, wear resistance, wet skid resistance, aging resistance and corrosion resistance are obviously improved.
The acrylic emulsion used in the invention improves the compatibility among each component, improves the performances of water resistance, compressive strength, tensile strength, adhesive strength, chemical resistance, ultraviolet resistance and the like of the surface treatment material, and the alkoxysilane compound has a three-dimensional network structure in a hydrogen bond form and is easy to combine with concrete hydrate. Potassium silicate is a tasteless, non-polluting, environmentally friendly material, is an alkaline natural material, has the effects of preventing and sterilizing harmful bacteria and fungi, and has excellent weather resistance, durability and flame retardancy. It penetrates into an inorganic base such as brick to form a physical and chemical bond, thereby improving the strength of the surface treatment material. In addition, the silicate imparts flammability and hydrophobicity to the surface-treated material, and the alkoxysilane may improve adhesion, tensile strength, flexural strength, compressive strength, and processability of the surface-treated material.
The titanium dioxide in the mixture can increase the adhesion, does not generate toxic gas even when burned in contact with a heat source, has little trace of carbonization, and makes the surface-treated material itself transparent. In order to further improve durability, tensile strength, tear strength, etc., silicon powder, which is a nano-sized powder having a single particle diameter of about 100 to 200nm to improve water tightness and strength of the surface treatment material, is further added to the composition of the present invention, and the density of the diatomite powder is low in order to shorten the drying time of the surface treatment material by its high absorptivity and chemical stability and increase the degree of adhesion to a concrete structure without interfering with the coloring of the surface treatment material.
At present, the organic solvent such as toluene is mainly used in the repair material for concrete structure in the prior art, and the organic solvent contains volatile substances and formaldehyde, which have adverse effects on the environment, whereas the solvent in the present invention is water and does not contain other organic solvents.
Compared with the prior art, the surface treatment material for the concrete structure and the preparation method thereof have the following advantages:
the surface treatment material does not contain an organic solvent which is not environment-friendly, but mainly comprises an environment-friendly acrylic emulsion, a water-based MMA resin, a water-based polyurea and an alkoxy silane, wherein the main solvent is water. Due to its excellent properties of durability, chemical resistance, and adhesion as a repair material, it can be used to maintain various concrete structures exposed to severe environments, and can prevent the repaired concrete structure from being destroyed again for a long time.

TABLE 3 evaluation results of Performance
As a result: the physical properties such as compressive strength, breaking strength, cohesive force, tensile strength and the like are obviously improved, the outdoor aging rate is not obviously changed, the durability is further enhanced, and the paint is excellent in acid resistance, alkali resistance and weather resistance and can resist the erosion of rain and snow. The performance of the polymer concrete protective coating material is obviously improved and is superior to that of the existing concrete protective material, after the existing concrete protective coating material is coated on the surface layer of concrete, because the aging speed is high, peeling, stripping, abrasion and discoloration occur after coating, the erosion of rainwater cannot be effectively resisted, the aging is accelerated, and the durability cannot be fully guaranteed.
The curing time is fast, and since it is coated in a thin film structure, it has the effects of preventing further erosion by water damage, simultaneously improving adhesion, making the material not easily fall off during use, and also improving freeze-thaw resistance, and having a deterioration rate of preventing concrete diseases due to ice, snow, etc. The cost of the future maintenance work is reduced, and the damage to the urban image is avoided.
The polymer concrete protective coating material has excellent compressive strength, super-strong cohesive force, flexural strength, more flexibility, more rigidity, good abrasion resistance and no joint, can be perfectly combined with concrete, asphalt, steel plates and marble, isolates the permeation of moisture and oxygen in the air, has good corrosion resistance and protective performance and durability, and is an excellent concrete protective material.
Detecting the four components,
The concrete protective coating materials obtained in examples 1 to 3 and comparative examples 1 to 3 were subjected to performance tests, and the results are shown in Table 5:

| Elongation (%) | 39 | 32 | 30.5 | 18 | 16.3 | 10.8 |
And (4) conclusion: from the examples 1-3, the polymer concrete protective coating material prepared by the invention has the compressive strength of 20-28 MPa, can bear the weight of a building structure, has the flexural strength of 4.3-7.6 MPa, has enhanced deformation capacity, can effectively resist the expansion deformation caused by temperature change, has the binding strength between the concrete protective coating material and the original structural surface, prevents the sequelae of peeling, falling and the like in the future, and has the binding strength of 2.3-3.9 MPa, which can be fully bound with the complex structural surface and is not easy to fall off. Meanwhile, the alkali resistance and the salt resistance of the embodiments 1 to 3 are excellent, and the corrosion resistance is better. The elongation at break is 30.5% -39%, the deformation resistance and tensile strength are obviously improved, the weather resistance is more extensive, and the temperature change is more greatly resisted.
As can be seen from the comparison of examples 1-3 with comparative examples 1-3, when the raw material components lack the aqueous acrylic resin emulsion, aqueous MMA resin emulsion or aqueous polyurea, the resulting material can not undergo chemical crosslinking reaction and can be cured into a tough network polymer structure, so that the properties of the material are reduced to different degrees, and the safety problem of the building structure can not be guaranteed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
