Drawings
In order that the detailed description of the present application may be clearly understood, reference will now be made to the accompanying drawings, which are used in a description of the detailed description of the present application, and which are, by way of illustration, specific embodiments of the present application.
Fig. 1 is a schematic flow chart of a construction method of a tile crack sealer provided by an embodiment of the application.
Detailed Description
In order to solve the technical problems described in the background section, as shown in fig. 1, the present application provides a tile crack sealer application method comprising the steps of:
s101: and selecting a bottom layer gap filler and a surface layer gap filler.
In the embodiment of the application, the selected bottom layer gap filler is aqueous emulsion and filler; the glass transition temperature of the aqueous emulsion is between 30 and 70 ℃, the glass transition of the aqueous emulsion is higher, and the hardness and the adhesive force of the cured bottom layer joint mixture are higher. In addition, the filler in the bottom layer gap filler is also beneficial to improving the hardness and the adhesive force of the cured bottom layer gap filler, so that the problem that the gap filler falls off for a long time is solved, and the long-term firmness of the gap filler is realized.
As a specific example of the present application, the glass transition temperature of the aqueous emulsion may be between 35 and 40 ℃ in order to make the hardness and adhesion of the cured crack sealer higher.
As another specific example of the present application, the aqueous emulsion selected for use may be an aqueous acrylic emulsion.
It should be noted that the filler contained in the underfill agent can increase the hardness of the underfill agent. The filler may be one commonly used in the art. As an example, granular sand can be used as the filler, so that the surface of the cured bottom layer joint mixture can be uneven, the adhesion of the surface layer joint mixture can be increased, and the risk of falling off of the surface layer joint mixture can be reduced. As a more specific example, the filler can comprise white sand and titanium dioxide, wherein the white sand comprises 70-80% (wt) of white sand with the particle size of 80-120 meshes and 20-30% (wt) of white sand with the particle size of 40-80 meshes.
In addition, in order to improve the bright effect of the seam beautifying agent, particularly the seam beautifying agent of glitter powder series after construction, the selected bottom layer gap filler can be white.
In addition, in the embodiment of the application, as an example, the bottom layer joint mixture can be an aqueous single-component color sand joint mixture, so that the bottom layer joint mixture can be filled in a glue bottle, and the bottom layer joint mixture is directly injected into gaps of ceramic tiles by using a glue gun during construction, thereby facilitating construction.
As a specific example of the present application, the selected underfill may also be an aqueous two-component epoxy color sand underfill.
In addition, in order to solve the problems of yellowing of the seam beautifying agent and incapability of flat matte, the binder in the surface layer gap filler selected in the embodiment of the application is aqueous acrylic emulsion, so that the surface layer gap filler is an acrylic seam beautifying agent and has excellent yellowing resistance, and the construction method solves the problems of yellowing of the seam beautifying agent and incapability of flat matte.
In addition, in order to improve the hardness of the seam beautifying agent after curing, when the surface layer gap filler is selected, the water-based acrylic emulsion with higher glass transition temperature can be selected as the binder in the surface layer gap filler. Specifically, the glass transition temperature of the aqueous acrylic emulsion may be between 30 and 70 ℃, more specifically, the glass transition temperature of the aqueous acrylic emulsion may be between 35 and 40 ℃ in order to make the hardness and adhesion of the cured caulk higher. In addition, the higher glass transition temperature of the binder in the surface layer gap filler is also beneficial to improving the overall stain resistance of the seam beautifying agent.
In addition, the acrylic seam beautifying agent is selected as the surface layer seam beautifying agent, and the ultraviolet resistance of the seam beautifying agent can be improved.
In addition, the surface layer gap filler is a single-component crack sealer for convenience of construction.
In addition, as a specific example of the present application, since the surface layer joint mixture is an acrylic joint mixture, in order to improve the adhesion between the bottom layer joint mixture and the surface layer joint mixture, according to the principle of similar compatibility, the aqueous emulsion in the bottom layer joint mixture can also be an aqueous acrylic joint mixture, so that after construction, chemical bond linkage can be established between the surface layer joint mixture and the bottom layer joint mixture, thereby greatly improving the compatibility and adhesion between the surface layer joint mixture and the bottom layer joint mixture, and further improving the firmness of the tile joint mixture.
S102: and filling the bottom layer joint mixture in the gaps of the ceramic tiles, wherein the gaps of the ceramic tiles are not filled with the bottom layer joint mixture.
As an example, when the selected underfill is an aqueous one-component color sand underfill, the underfill may be placed in a glue bottle so that the underfill is injected directly into the gaps between the tiles using a glue gun. Therefore, the single-component color sand joint mixture is beneficial to facilitating construction and improving the construction performance.
For another example of the present application, when the selected bottom layer joint mixture is a two-component epoxy color sand joint mixture, the epoxy color sand joint mixture needs to be mixed with a curing agent first, and then the mixed joint mixture is filled into the gaps of the ceramic tiles.
It should be noted that in order to leave some space for the top layer of caulk, the bottom layer of caulk fills only the portion of the tile gap near the bottom, which does not fill the entire tile gap. As a specific example of the present application, in order to improve the aesthetic effect, the distance between the upper surface of the underfill filled in the gap between the tiles and the surface of the tiles may be 0.5 to 1.5 mm. More specifically, it may be 1 mm.
As a specific example of the present application, the step may specifically be: firstly, filling a bottom layer joint mixture into a ceramic tile gap, then scrubbing the surface of the bottom layer joint mixture filled in the ceramic tile gap to scrub a gap with a certain depth, and finally enabling the distance between the upper surface of the bottom layer joint mixture filled in the ceramic tile gap and the surface of the ceramic tile to be 0.5-1.5 mm. More specifically, it may be 1 mm.
S103: and (4) leveling the surface of the bottom layer gap filler to ensure that the surface is flat and uniform.
In order to improve the aesthetic effect of the seam beautifying agent after construction, as an example of the application, before the surface layer joint sealing agent is filled, the surface of the bottom layer joint sealing agent can be leveled to be even. Specifically, this application can adopt the ox muscle to scrape the receipts material and smooth, wipes the gap with the sponge for the bottom joint mixture levels evenly.
S104: and after the bottom layer joint mixture is solidified, filling the surface layer joint mixture into the gaps of the ceramic tiles.
The step may be specifically, after the bottom layer joint mixture is cured to be free from sand, filling the surface layer joint mixture into the gaps of the ceramic tiles.
In the embodiment of the application, the selected surface layer gap filler is a single-component water-based acrylic emulsion, so that the surface layer gap filler can be pre-filled into a glue bottle and directly injected into gaps of tiles through a glue gun during construction. Then, the surface layer caulking agent was scraped off with a squeegee, followed by wiping the tile with a sponge.
The single-component water-based acrylic emulsion is selected as the binder of the surface layer joint mixture, so that the gaps of the ceramic tiles can not become black and mildew can not grow, and the glittering effect can be achieved after the glittering powder series products are constructed.
S105: and after the surface layer gap filler is cured, testing the hardness of the seam beautifying agent.
The step may specifically be: and after the surface layer gap filler is cured, pressing the gap of the ceramic tile, and inspecting the hardness of the gap filler.
It should be noted that, the application divides the construction process of the seam beautifying agent into two procedures: the bottom layer gap filler and the surface layer gap filler are constructed, and based on the selected bottom layer gap filler and the selected surface layer gap filler in S101, after the surface layer gap filler is cured, the seam beautifying agent has high hardness and is not easy to damage and fall off when contacting hard objects.
The above is a specific implementation manner of the construction method of the tile crack sealing agent provided by the embodiment of the application. In the specific implementation mode, the construction of the tile crack sealer is completed by two procedures of filling the bottom layer and the surface layer. Moreover, the glass transition temperature of the aqueous emulsion in the underfill is between 30 and 70 ℃, the glass transition of the aqueous emulsion is higher, and the hardness and the adhesion of the cured underfill are higher. In addition, the filler in the bottom layer gap filler is also beneficial to improving the hardness and the adhesive force of the cured bottom layer gap filler, so that the problem that the gap filler falls off for a long time is solved, and the long-term firmness of the gap filler is realized.
Moreover, the binder of the surface layer caulking agent is aqueous acrylic emulsion, so the surface layer caulking agent is acrylic seam beautifying agent which has excellent yellowing resistance, and the construction method solves the problems that the seam beautifying agent is yellow and cannot be flat matte.
In addition, in the construction method provided by the application, the single-component water-based acrylic emulsion is used as the binder of the surface layer gap filler, so that the gaps of the ceramic tiles cannot be blackened and mildewed, and the glitter powder series products can achieve the corresponding glittering effect after being constructed.
