Description

Technical Field

[0001] The invention belongs to the technical field of indoor building construction, and in particular relates to a ceramic tile integral splicing method and application thereof. Background Art

[0002] During the renovation of an old house, the original tiles on the floor and walls need to be removed and re-tiled. This process not only wastes time, but also increases the cost of renovation. If the old tiles are not removed and new tiles are directly pasted on the old tiles, if the new and old tiles are pasted only by conventional process methods, the new tiles on the floor will fall off and break due to the frequent movement of the floor tiles. The new tiles on the wall will fall off due to thermal expansion and contraction and the weight of the tiles themselves.

[0003] If new tiles are spliced ​​into a whole and then pasted on old tiles, the problem of tile breakage and falling can obviously be solved. Chinese patents CN 217924582 U, CN 214402541 U, CN 116378352 A, etc. respectively splice tiles by splicing cards, card slots, side grooves, etc., but such spliced ​​tiles are heavy and the adhesive is not strong when the tiles are pasted together, so they can only be laid on the ground without old tiles. For walls and other places where there are old tiles, they cannot be directly laid.

[0004] Therefore, a new type of spliced ​​tiles is needed, which can be laid directly on the old tiles without breaking them, and will not cause problems such as breakage and falling. Summary of the invention

[0005] The purpose of the present invention is to provide a novel tile splicing method, which can splice multiple tiles together.

[0006] The present invention achieves the above technical objectives through the following technical means.

[0007] A method for integrally splicing tiles comprises the following steps: Step S1: Lay the required tiles on a platform or a mold in pairs, with the front of the tiles facing the platform or the mold; Step S2: Leave gaps between tiles, and fix the gaps at the joints of the four tiles with a plastic cross of the required gap size to control the gap size between the tiles; Step S3: After the tiles are laid, first, the gaps between the tiles on the back of the tiles are completely sealed with caulking materials. After the sealing is completed, let it stand for 20-50 minutes until the surface of the caulking material reacts and becomes non-sticky, then the next process can be carried out; Step S4: Apply the interface agent on the back of the tile. After applying the interface agent, immediately lay the glass fiber mat and roll the glass fiber mat with a roller to completely immerse the glass fiber mat in the interface agent. Let it stand for 20-50 minutes until the surface of the interface agent reacts and becomes non-sticky, then proceed to the next step. Step S5: brushing resin on the mixed layer containing glass fiber mat interface, immediately laying glass fiber cloth, and rolling the glass fiber cloth with a roller to completely immerse the glass fiber cloth in the resin, brushing resin on the glass fiber cloth again, laying glass fiber mat, and rolling the glass fiber mat with a roller to completely immerse the glass fiber mat in the resin, repeating the above process, laying glass fiber cloth and glass fiber mat again, and determining the number of laying layers of glass fiber mat and glass fiber cloth according to the thickness, length and width and weight of the tile; Step S6: After the resin has completely reacted chemically, the entire tile is turned over, with the front side of the tile facing upward, and the gaps between the tiles are filled with a caulking agent or an epoxy grout to form a whole tile splicing product.

[0008] Furthermore, in step S2, the gap between the tiles is 1-3 mm.

[0009] Furthermore, the caulking material in step S3 is a mixture of epoxy resin and silica powder or a mixture of vinyl resin and silica powder.

[0010] Furthermore, the weight ratio of the epoxy resin to the silica powder is 100:200-500.

[0011] Furthermore, the weight ratio of the vinyl resin to the silica powder is 100:200-500.

[0012] Furthermore, the interface agent material in step S4 is a mixture of epoxy resin and coupling agent or a mixture of vinyl resin and coupling agent.

[0013] Furthermore, the mass ratio of the epoxy resin to the coupling agent is 1:2%-8%.

[0014] Furthermore, the mass ratio of the vinyl resin to the coupling agent is 1:2%-8%.

[0015] Furthermore, the number of layers laid in step S5 is 3-7 layers.

[0016] Another object of the present invention is to provide application of the ceramic tiles made by the above method in the renovation of old houses.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present application uses glass fibers to splice multiple tiles into a whole and then affix them to the polished old tiles. The spliced ​​tiles are firmly bonded to the glass fibers and are not easy to break. In addition, due to the presence of glass fibers, the bonding strength between the new tiles and the old tiles is increased, avoiding the problem of a weak bonding surface caused by direct bonding between the new and old tiles.

[0018] At the same time, the spliced ​​tiles of the present application can be spliced ​​in advance in the factory according to the area and shape of the house, and then the spliced ​​tiles can be moved to the place where they need to be laid, saving work time and cost.

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood. The present invention will be further described below in conjunction with the drawings and specific embodiments. Example 1

[0023] A method for integrally splicing tiles comprises the following steps: Step S1: Lay the tiles to be spliced ​​on a platform surface or a mold in pairs, with the front of the tiles facing the platform surface or the mold; the tile sizes here are the sizes that can be purchased on the market, for example: 100mm*100mm, 300mm*300mm, 300mm*600mm, 400mm*400mm, 600mm*600mm, 800mm*800mm, 600mm*1200mm, etc. The number of tiles to be spliced ​​can be determined as needed, and there is no limit here.

[0024] Step S2: Leave a 2mm gap between tiles, and fix the gap between the four tiles with a plastic cross 2; the gap in this step can be kept at 1-3mm as needed, and the width of the plastic cross is consistent with the gap between the tiles. The position of the plastic cross is as follows: Figure 1 shown.

[0025] Step S3: After the tiles are laid, first, the gaps between the tiles on the back of the tiles are completely sealed with caulking materials. After the sealing is completed, let it stand for 20-50 minutes (the specific time here is determined according to the temperature at that time). When the surface of the caulking material reacts and is no longer sticky, the next process can be carried out; the caulking material in this step is a mixture of epoxy resin and silica powder in a weight ratio of 100:200~500, or a mixture of vinyl resin and silica powder in a weight ratio of 100:200~500.

[0026] Step S4: Apply the interface agent on the back of the tile. After applying the interface agent, immediately lay the glass fiber felt and roll the glass fiber felt with a roller to completely immerse the glass fiber felt in the interface agent. Let it stand for 20-50 minutes (the specific time here is determined according to the temperature at that time). When the surface of the interface agent reacts and is no longer sticky, the next process can be carried out. The interface agent in this step is a mixture of epoxy resin and coupling agent in a weight ratio of 1:2%-8%, or a mixture of vinyl resin and coupling agent in a weight ratio of 1:2%-8%.

[0027] Step S5: Apply resin to the glass fiber mat mixed layer containing the interface agent, immediately lay glass fiber cloth, and roll the glass fiber cloth with a roller to completely immerse the glass fiber cloth in the resin, then apply resin to the glass fiber cloth, lay glass fiber mat, and roll the glass fiber mat with a roller to completely immerse the glass fiber mat in the resin, and repeat the above process. Figure 1 As shown, fiberglass cloth and fiberglass mat are laid in sequence, and the number of layers of fiberglass cloth and fiberglass mat is determined according to the thickness, length and width of the tile, and the weight of the tile. Finally, the number of layers of fiberglass cloth and fiberglass mat is 3-7 layers. Step S6: After the resin has completely reacted chemically, turn the entire tile over, turn the tile face up, and use a caulking agent or epoxy grout to fill the gaps between the tiles to form a tile splicing product. Figure 2 shown. Example 2

[0028] According to the method in Example 1, the four spliced ​​tiles were subjected to the destructive strength and destructive film number tests according to GB / T 3810.4-2016 Ceramic Tile Test Method Part 4: Determination of Fracture Film Number and Destructive Strength. The average destructive strength of the spliced ​​tiles was 447N, and the average number of fracture films was 3.29N / mm 2 The specific values ​​are shown in Table 1.

[0029] Table 1 Test results of the number of broken films and the breaking strength

[0030] The modulus of rupture refers to the maximum stress value that a ceramic tile can withstand when subjected to bending stress until it breaks. It reflects the bending resistance of the ceramic tile. As can be seen from Table 1, the average modulus of rupture of the spliced ​​ceramic tile is 3.29N / mm 2 , which is equivalent to 3.29MPa, or 3290 kg of force.

[0031] The breaking strength refers to the maximum pressure value that a ceramic tile can withstand before it breaks. It reflects the compressive resistance of the ceramic tile. The average breaking strength of the spliced ​​ceramic tile is 447N, which means that a force equivalent to 44.7 kg must be applied to the tile to make it break.

[0032] The above results show that the spliced ​​tiles can be safely transported and will not break during transportation. Example 3

[0033] The method of using the tiles spliced ​​in the above-mentioned embodiment 1 in the renovation of the tile floor is as follows: Step 01: Roughen the floor tiles of the old house, damage the glaze layer of the floor tiles, clean the floor tiles and wait for them to dry thoroughly; Step 02: Apply epoxy resin on the tile floor and wait for the epoxy resin to react chemically for 6-12 hours before proceeding to the next step; Step 03: Mix 50-150 mesh sand with epoxy resin to make epoxy sand, spread the epoxy sand on the tile floor, fill the gaps between the original tiles and tiles, and the roughened tiles with epoxy sand, and allow the chemical reaction to last for 6-12 hours before proceeding to the next step; Step 04: Apply epoxy resin on the surface of epoxy sand, and lay the entire tile product on the epoxy resin. After the chemical reaction is completed and dried, it will become the renovated floor. Example 4

[0034] The method of using the tiles spliced ​​in the above-mentioned embodiment 1 in the renovation of the tile wall is as follows: Step 001: Roughen the old wall tiles, destroy the glaze layer of the wall tiles, clean the tile wall and wait for it to dry thoroughly; Step 002: Apply epoxy resin on the wall tiles and wait for the epoxy resin to react chemically for 6-12 hours before proceeding to the next step; Step 003: Mix 50-150 mesh sand with epoxy resin to make epoxy sand, lay the epoxy sand on the wall tiles, fill the gaps between the original tiles and tiles, and the roughened tiles with epoxy sand, and proceed to the next process after the chemical reaction for 6-12 hours; Step 004: Apply epoxy resin on the surface of epoxy sand, and lay the entire tile product on the epoxy sand. After the chemical reaction is completed and dried, it will become the renovated wall. Example 5

[0035] The new and old tiles were bonded together according to the method in Example 3, and the bonding strength of each part was tested. The specific results are shown in Table 2.

[0036] Table 2 Adhesion strength test results

[0037] In the above results, the maximum force tested is the maximum force required to separate the tiles and glass fibers spliced ​​in Example 1, and the average value is 10.3 kN, which is equivalent to a force of 10.3 tons to separate them.

[0038] The bonding strength test is the force required to separate the new and old tiles after they are bonded in Example 3. The average value is 4.13 MPa, which is equivalent to a force of 4130 kg to separate them.

[0039] The results in Table 2 show that the new and old tiles are very strong after being bonded by glass fiber, and there is no risk of breakage or falling off.

[0040] The series of detailed descriptions listed above are only specific descriptions of feasible implementation modes of the present invention, but the present invention is not limited to the above-mentioned implementation modes. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
