Description
Technical Field
The application relates to a tile adhesive, in particular to a tile adhesive with high weather resistance, a preparation method and a use method thereof.
Background
The ceramic tile has the advantages of water resistance, easy cleaning and beautiful appearance, and is widely applied to decoration projects of inner and outer walls, floors and other parts of buildings. The fixing between the tiles and the building is usually by means of tile adhesives.
The traditional ceramic tile adhesive is prepared by taking cement, quartz sand and polymer adhesive as main materials and matching with a plurality of additives and uniformly mixing by stirring through a mixer, and has the characteristic of simple construction, but most of the existing ceramic tile adhesives have poor weather resistance and freeze-thaw resistance, gaps easily appear after the ceramic tile adhesive is frozen and shrunk, rainwater and the like are infiltrated into the gaps and frozen into ice, the volume is expanded, the gaps are enlarged, the ice in the gaps is refilled with water and then frozen and expanded, the structure of the ceramic tile adhesive is damaged under the repeated action, and ceramic tiles are fallen off.
Disclosure of Invention
In order to improve the freeze-thaw resistance effect of the ceramic tile binder and increase the heat insulation property of the ceramic tile binder, the application provides the ceramic tile binder with high weather resistance and the preparation method and the construction method thereof.
In a first aspect, the application provides a high weather-resistant tile adhesive, which adopts the following technical scheme:
the high-weather-resistance ceramic tile adhesive is prepared from the following raw materials in parts by weight: 30-40 parts of ordinary portland cement, 10-20 parts of modified silica aerogel, 55-70 parts of natural fine sand, 1-5 parts of fly ash, 1-3 parts of redispersible latex powder, 0.1-2 parts of cellulose ether and 25-40 parts of water; wherein the modified silicon dioxide aerogel is prepared by the silicon-containing compound participating in the in-situ polymerization process.
Through adopting above-mentioned technical scheme, silica aerogel has unique nanometer porous network structure, has lower heat, sound conductivity, consequently has fine thermal-insulated, syllable-dividing effect, but the silica aerogel surface that makes at present contains a large amount of hydrophilic groups (silicon hydroxyl), makes it easy moisture absorption in the air, meets water easy fracture to influence its heat, acoustic performance, restricted silica aerogel's application. Therefore, the silicon-containing compound is added to the preparation process of the silica aerogel, so that the hydrophilic groups on the surface of the silica aerogel are replaced by the hydrophobic groups, and the modified silica aerogel with hydrophobicity is obtained. The modified silica aerogel not only keeps good heat insulation and sound insulation effects, but also has good hydrophobicity, so that the modified silica aerogel is suitable for the ceramic tile binder. The modified silica aerogel is added into the ceramic tile binder, so that the heat insulation effect of the ceramic tile binder is improved, the influence of temperature change, climate change and the like on the ceramic tile binder is reduced, the freeze-thaw resistance effect of the ceramic tile binder is improved, and the sound insulation effect of the ceramic tile binder is also enhanced.
Preferably, the silicon-containing compound is octyltrimethoxysilane.
By adopting the technical scheme, the octyl trimethoxy silane contains methoxyl groups in molecules, has hydrophobicity, and is used for attacking silicon hydroxyl groups by oxygen atoms in the methoxyl groups according to a nucleophilic reaction mechanism to generate Si-O covalent bonds so as to modify the silicon dioxide aerogel.
Preferably, the preparation steps of the modified silica aerogel are as follows according to parts by weight:
1) sol-gel process: mixing 18-25 parts of tetraethyl orthosilicate, 10-15 parts of octyltrimethoxysilane, 75-90 parts of absolute ethyl alcohol and 6-10 parts of deionized water, stirring at 55-65 ℃ for 25-35 min, adding ammonia water to adjust the pH value to 7.5-8.5, and continuously stirring for 1.5-2.5 h to form a mixed solution a of modified silica wet gel and the solution;
2) aging of the gel: standing the mixed solution a for 45-50 h, continuously and slowly discharging the solution in the standing process, and slowly introducing absolute ethyl alcohol to ensure that the modified silica wet gel is completely immersed in the absolute ethyl alcohol to form a mixed solution b of the modified silica alcohol gel and the ethyl alcohol;
3) drying the gel: and drying the mixed solution b to obtain the modified silicon dioxide aerogel with hydrophobicity.
By adopting the technical scheme, in the step 1), tetraethyl orthosilicate is subjected to hydrolysis reaction to generate silanol, silicon-oxygen bonds are generated between silicon hydroxyl groups of two silanols through condensation reaction to form sol, meanwhile, silicon-oxygen bonds are generated between silicon hydroxyl groups of silanol and ethoxy groups of tetraethyl orthosilicate through polycondensation reaction, silicon-oxygen bonds are generated at positions where the polycondensation reaction is not generated, silicon atoms still carry 1-3 hydroxyl groups, and the hydroxyl groups are subjected to polycondensation reaction to generate primary colloidal particles with tetrahedral structures. According to the electrovalence rule, [ SiO ]4]Each vertex of a tetrahedron, i.e. O2-Can be used for at most two SiO4]Between tetrahedrons, each [ SiO ]4]All four vertexes of (a) and (b) are adjacent to [ SiO ]4]The connection is carried out to form a three-dimensional network structure, and the system is converted into sol from solution. The transformation process of sol to gel is that polymer or sol particles generated by polycondensation are aggregated and grown into small particle clusters, and the small particle clusters are connected into large particle clusters under mutual collision, and the gel can be formed after the whole container is filled with the large particle clusters. Hydroxyl on silicon atoms on the surface of the gel reacts with octyl trimethoxy silane moleculesAnd the methoxyl substituted hydroxyl is connected with silicon atoms on the surface of the gel, so that the gel has hydrophobicity.
In step 2), the strength of the gel is low immediately after the gel is formed, and in order to improve the strength of the gel, the gel needs to be aged, and after the gel is formed, a further hydrolytic polycondensation reaction is called aging of the gel. In the aging process, the gel monomer or the smaller gel cluster in the solution continues to be subjected to polycondensation to form a gel network, the gel network is crosslinked, the gel network gradually becomes coarse, and the strength becomes strong.
In the step 3), a large amount of ethanol solution exists around the aged alcogel skeleton, and the alcogel is dried to obtain the aerogel.
Preferably, the stirring manner in the step 1) is ultrasonic oscillation.
Through adopting above-mentioned technical scheme, the ultrasonic oscillation mode has promoted the emergence of reaction in the solution, and more even to the stirring effect of each position of solution, and the gel formation reaction is also more even.
Preferably, the step 3) adopts a supercritical drying mode.
By adopting the technical scheme, if other drying methods are adopted, the volume of the gel is reduced due to the surface tension of the gas-liquid interface. When supercritical drying is adopted, ethanol is used as a drying medium, when the ethanol is beaten to the critical condition, a gas-liquid interface disappears, the surface tension does not exist any more, and the ethanol is discharged under the condition to obtain the aerogel with the same or similar skeleton structure as the alcogel.
Preferably, the raw materials of the tile adhesive also comprise 0.1-2 parts of an early strength agent.
By adopting the technical scheme, the Portland cement has low early strength and high later strength, and the cement hydration speed can be accelerated by adding a proper amount of early strength agent, so that the early strength of the ceramic tile adhesive can be improved.
Preferably, the early strength agent is calcium formate.
By adopting the technical scheme, in a portland cement system, calcium formate has coagulation promoting and early strength effects because of the formazan in the calcium formateAcid radical ion HCOO-Analogous C capable of forming AHt and AFm3A·3Ca(HCOO)2·30H2O、C3A·Ca(HCOO)·10H2O, etc., greatly shortening the setting time of the cement. In addition, calcium formate promotes calcium silicate hydration because of HCOO-Ion diffusion velocity ratio Ca2+Ions are fast and thus can penetrate to C3S and C2Hydration layer of S, accelerated Ca (OH)2Precipitation of calcium silicate and decomposition of calcium silicate. HCOO-The ions can further bind the silicon atoms to OH through chemical action-Reacting to crosslink adjacent silicate groups, promoting the formation of C-S-H gel and improving the hardening strength of cement mortar.
In a second aspect, the application provides a preparation method of a high-weatherability tile adhesive, which adopts the following technical scheme: a preparation method of a high-weather-resistance ceramic tile adhesive comprises the following preparation steps: adding ordinary portland cement, modified silica aerogel, natural fine sand, fly ash, redispersible latex powder, cellulose ether and an early strength agent into water, stirring, uniformly stirring, and standing to form the tile binder.
By adopting the technical scheme, if water is added into cement, the cement immediately begins to hydrate and generate heat when contacting with the water, the cement forms lumps and is difficult to form homogeneous ceramic tile adhesive, so other raw materials of the adhesive are added into the water.
In a third aspect, the application provides a construction method of a high-weatherability tile adhesive, which adopts the following technical scheme: a construction method of a high-weather-resistance ceramic tile adhesive comprises the following steps:
1) soaking the ceramic tile in water;
2) cleaning the smearing surface;
3) uniformly coating a ceramic tile adhesive on the coating surface;
4) bonding the ceramic tile on the ceramic tile adhesive on the smearing surface;
5) the tile is gently pressed or knocked towards the direction of approach to the application surface and the air is vented.
Through adopting above-mentioned technical scheme, the ceramic tile that does not soak the processing can absorb the moisture of ceramic tile binder, influences the ceramic tile binder and solidifies, causes the binder hollowly easily, the ceramic tile drops, has consequently carried out the soaking processing to the ceramic tile. If the painted surface is not cleaned, stains such as oil stains, mold release agents, floating dust and the like are remained, the tile adhesive is directly adhered to the stains, and is very insecure, so that the tiles and the adhesive are easy to fall off, and the painted surface is cleaned before painting.
Preferably, the tile is prevented from being subjected to a load for 24 hours after it has been adhered to the application surface.

Performance test
Tile adhesive samples were prepared according to the methods of examples 1 to 13 and comparative examples 1 to 3, and the properties of the tile adhesives were measured according to the following methods, and the results are shown in table 2.
Tensile adhesive strength: testing according to JC/T547-2005 standard;
coefficient of thermal conductivity: the test was carried out according to GB/T10294-2008 and ISO 8302-1991.
TABLE 2 results of the Performance test of examples 1 to 13 and comparative examples 1 to 3
As can be seen from Table 2, after the tile adhesive is subjected to soaking, thermal aging and freeze-thaw cycling treatment in the standard JC/T547-; compared with the commercially available tile adhesive, the tensile adhesive strength of the tile adhesive is higher than that of the commercially available tile adhesive in the comparative example 3 after soaking, thermal aging and freeze-thaw cycling treatment, which shows that the tile adhesive has better soaking resistance, thermal aging resistance and freeze-thaw cycle resistance, i.e. high weather resistance, than the commercially available tile adhesive. The lower the thermal conductivity, the poorer the thermal conductivity of the tile adhesive, i.e. the better the thermal insulation, and it can also be seen in combination with the thermal conductivity in table 2 that the tile adhesive of example 6 has better thermal insulation.
Combining the coefficient of heat conductivity and tensile adhesive strength in table 2, can see that the coefficient of heat conductivity height of the ceramic tile binder of this application is the negative correlation rather than the weatherability is strong and weak, and the coefficient of heat conductivity is lower more promptly, and the weatherability is higher, consequently the ceramic tile binder of this application has the advantage of high weatherability and high heat-proof quality simultaneously concurrently.
Comparing example 6 with comparative example 1, the tensile adhesive strength of the tile adhesive of example 6 after being respectively subjected to soaking, heat aging and freeze-thaw cycling is higher than that of the tile adhesive of comparative example 1, indicating that the hydrophobically modified silica aerogel provides the tile adhesive with better weather resistance than unmodified silica aerogel. This is probably due to the fact that unmodified silica aerogel has better hydrophilicity, absorbs moisture during soaking and freeze-thaw cycles, and influences the internal structure of the silica aerogel, thereby causing a reduction in the tensile adhesive strength of the tile binder.
Compared with the comparative example 2, the tensile adhesive strength of the tile adhesive of the embodiment 6 after being respectively treated by soaking, heat aging and freeze-thaw cycles is higher than that of the tile adhesive of the comparative example 2, which may be caused by the fact that the modified silica aerogel is not added in the comparative example 2, so that the heat transfer effect is improved, the resistance to the severe conditions such as soaking, heat aging and freeze-thaw cycles is reduced, the structural stability is greatly influenced, and the tensile adhesive strength of the tile adhesive is reduced.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
