Description
Technical Field
The invention relates to the technical field of building materials, in particular to a water-retaining agent, a tile adhesive and a preparation method thereof.
Background
The ceramic tile is one of the commonly used decorative materials of walls and floors in the building industry, the ceramic tile glue is widely used as an adhesive for sticking the ceramic tile at present, and the ceramic tile glue with the largest using amount in the market is a cement-based dry powder product added with additives such as dispersible latex powder and the like. The manual construction process of ceramic tile glue spreading for ceramic tiles comprises the steps of plastering and scraping teeth on the wall and the ground, scraping the slurry on the back of the ceramic tile, and then spreading and pasting the ceramic tile. But at the ceramic tile shop subsides in-process, general constructor can have smeared the ceramic tile again after thick liquids in large tracts of land for the improvement efficiency of paving, and some ceramic tile glue is white because the surface crust of the time of placing is too of a specified duration is turned into white this time to because the hydroscopicity on wall ground can lead to the ceramic tile glue to lose water, the hydration in later stage is not enough, leads to the ceramic tile to glue later stage adhesion strength greatly reduced, produces the risk that hollowing, fracture fall the brick even.
The air-drying time is specified as an important index of the construction performance in an industry standard JC _ T547-2017 ceramic tile adhesive: the air-drying time refers to the maximum time interval from the time when the surface of the adherend is coated with glue to the time when the standard tensile adhesive strength of the laminated test piece is greater than or equal to 0.5MPa, and is the time interval from the time when the laminated test piece is hung on a concrete slab in batch to the time when the ceramic tile is laid. The tensile bonding strength of the C1 and C2 types is more than 0.5MPa in the open time of more than 20 minutes, and the tensile bonding strength of the E type with the longer open time is more than 0.5MPa in more than 30 minutes. The main influence factor of the airing time is the water retention property of the tile glue product, the conventional method for prolonging the water retention property is to add cellulose ether into the tile glue, the water retention property can be improved to more than 90 percent by adjusting and optimizing a formula (such as CN201711370568.2 and CN 201910428657.0), but the excessive addition of the cellulose ether can influence the setting time and the strength of the tile glue.
In actual construction, the tile area is developed towards a larger direction, so that the paving difficulty is relatively increased. The tile flatness and the height difference of adjacent tiles have the condition of back-and-forth adjustment, a constructor can only lay and paste tile areas of 10-20 square tiles in a day, and the airing time performance of 20-30 minutes can not guarantee that the laying quality of the tiles can be met under the normal laying speed of the constructor.
In addition, the tile paving has the problems of high labor cost and low efficiency, and can be replaced by automatic machine construction in the future with high probability. Machine construction can produce the new demand of storage, transportation, construction operating time to the ceramic tile glue, can produce subversive change to the construction method, storage mode, the operation route that the ceramic tile glued, and the comprehensive properties that current ceramic tile glued still can not match the requirement of the automatic construction of machine.
Therefore, the ceramic tile glue with super water retention performance and super long airing time has important practical significance.

Test examples
(1) The formulations of the water-retaining agents in examples 1 to 8 and comparative examples 1 to 10 are shown in table 1:
TABLE 1
(2) And (3) performance testing:
the tile adhesives prepared in examples 1 to 8 and comparative examples 1 to 10 were subjected to performance tests according to JC/547-2017 ceramic tile adhesive and JGJT/70-2009 basic performance test method for building mortar, and the results are shown in Table 2.
Wherein E is0The tensile bonding original strength is expressed in MPa; e1Tensile bond strength (no vibration) after soaking in water is expressed in MPa; e2Tensile bond strength after heat aging is expressed in MPa; e3The bonding strength after freeze-thaw cycling is expressed in units of MPa; e4The tensile bonding strength of the film is expressed by the unit of MPa, and the air-drying time is 20 min; e5Tensile bond strength in MPa with an open time of 40min is indicated.
TABLE 2
As can be seen from Table 2, the tile adhesives of examples 1-8 have a water retention of 95% or more, an initial setting time of 120min or more, are easy to construct, have excellent adhesion properties and high initial strength, and have satisfactory strength after immersion, thermal aging, freeze-thaw treatment or air-drying. In addition, the proportion and the dosage of the water retention agent in the embodiment 3 are the best water retention effect, and the strength of the tile adhesive also meets the national C1 level standard.
The tile glue in comparative examples 1-4 has a water retention rate of over 85%, but has short initial setting time, is inconvenient to construct, has poor adhesive property, and cannot meet the requirements for strength after thermal aging, freeze thawing treatment or airing. Combining the results of example 3 and comparative example 5, it is clear that the use of an active agent outside the scope of the present invention is not favorable for the water retention, initial setting time and adhesive properties of the tile adhesive, and the strength of the tile adhesive is much reduced after heat aging or freeze-thaw treatment, and thus the tile adhesive cannot meet the requirements. Combining the results of example 3 and comparative example 6, it is clear that the use of the uric acid in place of the hyaluronic acid of the present invention is not favorable for the water retention, initial setting time, adhesive property and strength of the tile adhesive, and the strength of the tile adhesive is much reduced after immersion, heat aging or air-drying, and thus the tile adhesive cannot meet the requirements. Combining the results of example 3 and comparative examples 7, 8, 9 and 10, it can be seen that if the ratio of the raw materials in the formula of the water-retaining agent is not within the range of the present invention, the water retention rate and the adhesive property of the tile adhesive are not good, and the strength of the tile adhesive is greatly reduced after soaking or freeze-thaw treatment, which cannot meet the requirement.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
