Description

Ceramic tile adhesive and preparation method thereof
Technical Field
The application relates to the field of tile paving, in particular to a tile adhesive and a preparation method thereof.
Background
In daily construction, tile placement is usually carried out using cement, tile glue, or the like. Cement is a relatively traditional and widely applied material, and after the cement is dried and fixed, the ceramic tile and the veneers are bonded by mechanical biting force, so that the cement has the advantages of low price, easily available raw materials and simple preparation; however, the defects are obvious, the thickness of the paving is thick, and hollowness is easy to generate. Thus, another material, tile glue, was derived. The tile glue is a new material for modern decoration for sticking tile, face brick, floor tile and other decorative materials. The slurry is utilized to permeate into capillary holes on the back of the ceramic tile, and the adhesive force is formed after induction. The bonding mode of the tile adhesive ensures that phenomena such as hollowing, falling off and the like are not easy to occur between the tile and the veneers.
If the usage amount of the tile adhesive can be further reduced, the adhesive layer is thinned, so that the space and the material consumption can be saved, but the tile is easily detached due to insufficient adhesive strength when the usage amount of the tile adhesive is reduced. Therefore, there is still a need for improvement.
Disclosure of Invention
In order to improve the bonding strength of the tile adhesive, the application provides the tile adhesive and a preparation method thereof.
In a first aspect, the application provides a tile adhesive, which adopts the following technical scheme:
the tile adhesive comprises the following raw materials in parts by weight: 450-600 parts of filler, 450-550 parts of cement, 15-30 parts of vinyl acetate/ethylene copolymerized rubber powder, 1-2 parts of hydroxypropyl methyl cellulose, 0.2-0.6 part of starch ether, 5-10 parts of sodium formate, 0.8-1.5 parts of polypropylene fiber and 180-220 parts of water.
By adopting the technical scheme, under the common coordination of hydroxypropyl methylcellulose, sodium formate and polypropylene fibers, when the hydroxypropyl methylcellulose is reacted with water in a stirring way, a uniform network complex structure can be rapidly formed in the system, and the sodium formate is rapidly attached to the network structure and uniformly distributed on all parts of the system. Moreover, the speed of delaying the saturation of calcium ions can be further improved, so that the system has longer reaction time, and the strength of the adhesive is improved.
The various raw materials are connected together due to the evenly distributed network structure generated in the system. When force acts on the ceramic tile and is transferred to the ceramic tile glue, the ceramic tile glue is used as a whole to bear the force, and the force is rapidly distributed, namely, the force cannot be intensively attacked at a certain point, so that the bonding strength between the ceramic tile and the ceramic tile glue is further improved, and the ceramic tile can be firmly bonded on a veneer.
Preferably, the mass ratio of the hydroxypropyl methylcellulose to the sodium formate to the polypropylene fibers is 1: (3-5): (0.4-0.6).
By adopting the technical scheme, the mass ratio among the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fibers is further limited, the hydroxypropyl methylcellulose and the polypropylene fibers can form a network structure with flexibility and toughness, and the sodium formate can be more firmly attached to the network structure, so that the adhesive strength of the adhesive is further improved.
Preferably, the polypropylene fiber has a single fiber diameter of 22-32mm and a hydroxypropyl methylcellulose viscosity of 10W.
By adopting the technical scheme, the single fiber diameter of the polypropylene fiber and the viscosity of the hydroxypropyl methylcellulose are further limited, and the matching effect between the polypropylene fiber and the hydroxypropyl methylcellulose and between the hydroxypropyl methylcellulose and sodium formate is improved, so that the network structure is more stable, and the polypropylene fiber and the hydroxypropyl methylcellulose are rapidly dispersed in a system and uniformly dispersed.
Preferably, the filler is one or more of river sand, stone tailing Dan Wei placer and slag powder.
Preferably, the filler is river sand, stone tailing Dan Wei placer and slag powder, and the mass ratio of the river sand to the stone tailing Dan Wei placer to the slag powder is 1: (0.2-0.3): (0.1-0.18).
By adopting the technical scheme, the fillers with specific types and proportions are selected to be matched with each other, and are quickly attached to the network structure together and filled in the pores, so that the pores in the system are reduced, the compactness is increased, and the strength is improved. Due to the support of the network structure, the filler is not easy to displace and sink after being dispersed, and has higher stability.
Some tiles laid on the interior walls of a household may be exposed to high intensity, prolonged exposure to sunlight for a long time due to location problems, or severe moisture on the walls during the spring (especially in the southern areas), which may increase the risk of tile falling. The technical scheme provided by the application can effectively improve the stability of the adhesive, thereby improving the applicability of the product in different scenes.
Preferably, the river sand is 80-120 meshes, the Dan Weidan tailing is 50-80 meshes, and the slag powder is 120-160 meshes.
By adopting the technical scheme, the particle size of each filler is further limited, the porosity is reduced, the system is plump, and meanwhile, the filler is matched with the vinyl acetate/ethylene copolymerized rubber powder, so that the loss of cohesive force is reduced, and the tensile bonding strength of the adhesive is improved.
In a second aspect, the application provides a preparation method of a tile adhesive, which adopts the following technical scheme:
the preparation method of the tile adhesive comprises the following steps:
uniformly mixing the raw materials except water; then adding water to continuously and uniformly mix to obtain the finished product.
The preparation method is simple and quick, has lower requirements on equipment, is beneficial to reducing the cost and is suitable for popularization in the field.

By adopting the technical scheme, the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fibers are dispersed in advance, the mutual mixing of the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fibers is promoted, and then the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fibers are added and mixed with other raw materials, so that the matching effect among the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fibers is fully exerted, and the bonding strength of the adhesive is further improved.
In summary, the application has the following beneficial effects:

Moreover, the speed of delaying the saturation of calcium ions can be further improved, so that the system has longer reaction time, and the strength of the adhesive is improved.
2. The various raw materials are connected together due to the evenly distributed network structure generated in the system. When force acts on the ceramic tile and is transferred to the ceramic tile glue, the ceramic tile glue is used as a whole to bear the force, and the force is rapidly distributed, namely, the force cannot be intensively attacked at a certain point, so that the bonding strength between the ceramic tile and the ceramic tile glue is further improved, and the ceramic tile can be firmly bonded on a veneer.
3. The filler with specific types and proportions is selected to be matched with each other, and is quickly attached to the network structure together and filled in the pores, so that the pores in the system are reduced, the compactness is increased, and the strength is improved. Due to the support of the network structure, the filler is not easy to displace and sink after being dispersed, and has higher stability.

Performance test
Detecting an object: examples 1 to 11 and comparative examples 1 to 5.
Detection specification: the specification of the bricks is 40mm by 40mm, and the specification of the cement base plate is 70mm by 70mm.
The detection method comprises the following steps: the samples were tested according to JC/T547-2017 ceramic tile adhesive, and the tensile bonding strength (original strength), tensile bonding strength after soaking and heat aging bonding strength were calculated for 28 days.
The detection results are shown in Table 2.
TABLE 2
As can be seen from the comparison of the data in Table 2 between examples 1-3 and comparative examples 1-3, the tensile bond strength of the tile adhesives of examples 1-3 can still be maintained at a higher level after the original strength, heat aging treatment, and water immersion treatment, than the tensile bond strength of comparative examples 1-3. The ceramic tile adhesive prepared by the cooperation of hydroxypropyl methyl cellulose, sodium formate and polypropylene fibers has a tough network structure, so that the ceramic tile adhesive has good tensile bonding strength. Meanwhile, the adhesive has good flexibility, can be suitable for various different scenes, and can show good tensile bonding strength. As is clear from the comparison of the data in comparative example 4, although the increase in the cement amount can improve the tensile bond strength to some extent, it is not possible to provide a good base system for the blending of other raw materials, and the cement composition exhibits adverse effects in both heat aging treatment and water immersion treatment. It is understood from the data of comparative example 5 that the ratio of the hydroxypropyl methylcellulose, sodium formate, and polypropylene fibers is also important, and the performance of the tile adhesive cannot be sufficiently improved when the ratio of the hydroxypropyl methylcellulose, sodium formate, and polypropylene fibers is out of the range of the present application.
As can be seen from the comparison of the data of examples 1 and 4 and example 5 in table 2, the use ratio and the use amount of the hydroxypropyl methylcellulose, the sodium formate and the polypropylene fiber are further limited, and the matching relationship between the three can be more fully exerted, so that the original strength, the performance after the heat aging treatment and the performance after the water immersion treatment of the tile adhesive are improved.
As can be seen from the comparison of the data of examples 1 and 6 and example 9 in Table 2, the tensile bonding strength of the prepared tile adhesive is obviously improved when the specific river sand, stone tailing Dan Wei placer and slag powder are defined for matching. The comparison of the data in the embodiment 7 shows that when the filler is further limited to be matched in a specific proportion, the pores in the system can be better filled, and the tensile bonding strength of the ceramic tile adhesive after heat aging and water immersion treatment is improved by relying on a network structure. Meanwhile, it is understood from example 10 that the filler of a specific kind can further exert its filling effect after being blended in a specific mesh.
From a comparison of the data in Table 2 for example 1 and example 8, it is clear that the different parameters of hydroxypropyl methylcellulose and polypropylene fibers also have an effect on the performance of the tile adhesives. The hydroxypropyl methylcellulose and polypropylene fibers which are specifically selected can have better matching effect.
As can be seen from the comparison of the data of example 1 and example 11 in table 2, the pretreatment of hydroxypropyl methylcellulose, sodium formate and polypropylene fibers is beneficial to better dispersing effect in the system, and a stronger network structure is formed, so that the performance of the tile adhesive is improved.
The present embodiment is only for explanation of the present application and is not to be construed as limiting the present application, and modifications to the present embodiment, which may not creatively contribute to the present application as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present application.
