Description

  The present invention relates to a tile repair method and an injection, and more particularly to a tile repair method for tiles arranged on an underlying wall via an adhesive member and an injection used for the tile repair method.

  On the outer wall, inner wall, floor, etc. of a building where tiles are placed on the base wall via adhesive members, etc., the adhesive force between the base wall and the adhesive member decreases due to deterioration over time, and the adhesive member from the base wall The tile may be lifted by peeling off. When the tile float occurs, there is a risk that the tile will fall, so it is necessary to repair the tile float.

  As a method for repairing such a tile, as disclosed in Japanese Patent Laid-Open No. 5-18324 (Patent Document 1) and the like, a two-component type epoxy resin of a main component and a curing agent component is formed in a portion where the floating occurs. A method of injecting the composition may be mentioned. In Patent Document 1, an epoxy resin composition is obtained by mixing 660 g of a main ingredient component and 330 g of a curing agent component, left at 20 ° C. for 40 minutes, filled into a grease gun, and injected with 50 g of the epoxy resin composition by the grease gun. Is disclosed.

Japanese Patent Laid-Open No. 5-18324

  However, in the said patent document 1, this inventor revealed for the first time that the predetermined performance of an epoxy resin composition may not be obtained. In this case, since the base wall and the adhesive member cannot be bonded, the floating of the tile cannot be repaired. For this reason, it is necessary to inject | pour the epoxy resin composition which has predetermined | prescribed performance, and to perform adhesion | attachment with a base wall and an adhesive member again, and there exists a problem that workability is bad.

  In view of the above problems, an object of the present invention is to provide a tile repair method and an injection agent that improve workability.

  The problem that the predetermined performance of the epoxy resin composition cannot be obtained in Patent Document 1 is a measurement error when mixing a predetermined amount of a main agent component and a predetermined amount of a hardener component at a construction site where tile repair is performed. The present inventor has paid attention to the fact that it is caused by the above. Then, this inventor completed this invention as a result of earnestly examining the means which prevents the measurement mistake of a main ingredient component and a hardening | curing agent component in a construction site.

  That is, the tile repair method according to one aspect of the present invention is a tile repair method that is arranged on an underlying wall via an adhesive member, and includes a first agent containing an adhesive component and a curing agent component. A step of preparing an injection containing at least one of the first agent and the second agent further containing a thixotropic agent; and a state in which the adhesive member floats from the base wall, A step of forming a hole penetrating the adhesive member in the joint formed in the step, and mixing the first agent and the second agent with the same weight, and injecting the mixed injection into the hole, And the step of preparing the adhesive member and the step of preparing the adhesive component, the curing agent component, and the thixotropic agent when the same amount of the first agent and the second agent are mixed in the bonding step. And a step of preparing so as to be a predetermined ratio.

  The injecting agent of the present invention is used for repairing tiles arranged on the base wall via an adhesive member, and is injected from a hole formed in the adhesive member in a state where the adhesive member floats from the base wall. An injection agent for bonding a wall and an adhesive member, comprising: a first agent containing an adhesive component; and a second agent containing a curing agent component, wherein at least one of the first agent and the second agent is shaken. It further contains a modification-imparting agent, and is prepared so that the adhesive component, the curing agent component, and the thixotropic-imparting agent are in a predetermined ratio when the first agent and the second agent of the same weight are mixed. .

  According to the tile repair method and the injection agent in one aspect of the present invention, the thixotropic agent is contained in at least one of the first agent and the second agent, and the same amount of the first agent and the second agent are mixed. The adhesive component, the curing agent component, and the thixotropic agent are prepared in advance so as to have a predetermined ratio. For this reason, at the construction site where the tile is repaired, it is only necessary to weigh the first agent and the second agent, so even if the first agent and the second agent are mistaken, The adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio. Thereby, since the injecting agent after mixing has a predetermined performance, the floating of the tile can be repaired by injecting the injecting agent between the base wall and the adhesive member. Therefore, workability can be improved.

  Further, the present inventor has found that the problem that the predetermined performance of the epoxy resin composition cannot be obtained in the above-mentioned Patent Document 1 is determined after mixing the main component and the curing agent component at the construction site where the tile is repaired. I found out that it was due to the passage of time. When the main agent component and the curing agent component are mixed, curing starts, and when time elapses, the adhesive ability of the injecting agent decreases, and a predetermined performance cannot be obtained. Therefore, the inventor of the present invention has completed the present invention as a result of earnestly examining means for suppressing the injection agent from being cured by the reaction of the main agent component and the curing agent component before the injection.

  That is, the tile repair method according to another aspect of the present invention is a tile repair method arranged on an underlying wall via an adhesive member, and includes a first agent containing an adhesive component and a curing agent component. A step of preparing an injection containing at least one of the first agent and the second agent further containing a thixotropic agent; and a state in which the adhesive member floats from the base wall, A step of forming a hole penetrating the adhesive member in the joint formed in the step, and a step of adhering the base wall and the adhesive member by injecting the first agent and the second agent into the hole portion while mixing. It has.

  In the tile repair method according to one aspect of the present invention, preferably, in the bonding step, the first agent and the second agent are mixed and injected into the hole.

  Thereby, since the 1st agent and the 2nd agent can be mixed just before the hole which should be inject | poured, hardening of an injectant can be suppressed until just before injection | pouring to a hole. For this reason, since the injection has a predetermined performance, the floating of the tile can be repaired by injecting the injection between the base wall and the adhesive member. Therefore, workability can be further improved.

  Preferably, in the tile repair method according to one aspect and the other aspect of the present invention, the step of preparing the first agent and the second agent so that the viscosity of the first agent is the same as the viscosity of the second agent. It further has the process of preparing.

  Thereby, since a 1st agent and a 2nd agent can be easily mixed in a construction site, a workability can be improved more.

  Preferably, in the tile repair method according to one aspect and the other aspect of the present invention, the preparing step includes a Ti value of 6 when the same amount of the first agent and the second agent are mixed in the bonding step. The process further includes the step of preparing the first agent and the second agent so as to be 5 or more and 8.0 or less.

  Thereby, after inject | pouring an injection into a hole, the dripping of an injection can be suppressed. For this reason, since the adhesiveness between a base wall and an adhesive member can be improved, workability | operativity can be improved more.

  According to the tile repair method and the injection agent of the present invention, workability can be improved.

It is sectional drawing which shows roughly the state which implemented the repair method of the tile in embodiment of this invention. It is sectional drawing which shows roughly the tile repaired in embodiment of this invention. It is a figure which shows the injections 1-4 injected into the hole in Example 1, (A) is the injection 1, (B) is the injection 2, (C) is the injection 3. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

  With reference to FIG.1 and FIG.2, the repair method and injection | pouring of the tile of one Embodiment of this invention are demonstrated.

  First, the injection agent in the embodiment of the present invention will be described. As shown in FIG. 1, the injection 11 is used for repairing the tile 14 arranged on the base wall 12 via the adhesive member 13, and the adhesive member 13 is in a state where the adhesive member 13 is lifted from the base wall 12. The base wall 12 and the adhesive member 13 are bonded to each other by being injected from the hole 15 formed in the above.

  The injection agent 11 includes a first agent containing an adhesive component and a second agent containing a curing agent component, and may further contain other components, but the first agent and the second agent. It is preferable to consist of. At least one of the first agent and the second agent further contains a thixotropic agent, and the first agent and the second agent preferably contain a thixotropic agent. When the same weight of the first agent and the second agent are mixed, the adhesive component, the curing agent component, and the thixotropic agent are prepared in a predetermined ratio. The first agent and the second agent are mixed immediately before use.

  Here, “when the same amount of the first agent and the second agent are mixed, the adhesive component, the curing agent component, and the thixotropic agent are prepared in a predetermined ratio”. “Weight” means an amount that can be regarded as comparable when the first agent and the second agent are weighed in the construction site where the tile is repaired, and includes a measurement error at the construction site. That is, “the same weight” means that the weight of the first agent and the weight of the second agent are completely the same, and the case where there is a difference between the weight of the first agent and the weight of the second agent (first The weight of the agent: The weight of the second agent = 1.0: 1.2 to 1.2: 1.0). However, it is preferable that the hardening | curing agent component in a 2nd agent is more than the weight which all the adhesive agent components in a 1st agent can react.

  Further, the “predetermined ratio” means a ratio at which the adhesive component, the curing agent component, and the thixotropic agent function as an injection agent, and is preferably a ratio that provides an optimum composition as an injection agent.

  The first agent contains an adhesive component that adheres the base wall 12 and the adhesive member 13. The adhesive component is not particularly limited, and for example, epoxy resin, bisphenol A, or the like can be used. The first agent may further contain a thixotropic agent, an additive and the like, and is preferably composed of an adhesive component, a thixotropic agent and an additive.

  The second agent contains a curing agent component that cures the adhesive component. Although a hardening | curing agent component is not specifically limited, For example, an aliphatic amine etc. can be used. The second agent may further contain a thixotropic agent, an additive and the like, and is preferably composed of a curing agent component, a thixotropic agent and an additive.

  The thixotropic agent is a viscosity modifier for suppressing dripping of the injection 11. In this embodiment, since the injection 11 is arranged in the gap 16 between the base wall 12 extending in the vertical direction and the adhesive member 13 bonded to the tile 14, the injection 11 is injected downward in the vertical direction. In order to prevent the agent 11 from sagging, the injection agent 11 contains a thixotropic agent to increase the viscosity. The thixotropic agent is not particularly limited, and for example, silica powder or the like can be used.

  The injectable 11 after mixing preferably has a viscosity of 99 Pa · s or higher when measured at 2 rpm in accordance with JIS Z8803, and preferably has a viscosity of 137 Pa · s or higher. It is more preferable.

  Moreover, the viscosity of the 1st agent and the viscosity of the 2nd agent are the same. “The viscosity is the same” includes a category in which the first agent and the second agent can be easily mixed at the construction site where the tile is repaired. That is, “the viscosity is the same” means that the difference between the viscosity of the first agent and the viscosity of the second agent is exactly the same as the viscosity of the first agent and the viscosity of the second agent is 25 Pa · s or less. Including the case of In addition, the viscosity in this case is a value when measured at a rotation speed of 20 rpm in accordance with JIS Z8803.

  The Ti value of the injection 11 in which the first agent and the second agent are mixed is preferably 6.5 or more and 8.0 or less, more preferably 6.9 or more and 7.6 or less, More preferably, it is 2 or more and 7.6 or less. When the Ti value is 6.5 or more, it is possible to prevent the infusate 11 from dripping downward in the vertical direction while the injecting agent 11 is injected, and when the Ti value is 7.2 or more, the injecting agent 11 is dripped. Can be further suppressed. When the Ti value is 8.0 or less, mixing of the first agent and the second agent is easy, and when it is 7.6 or less, mixing of the first agent and the second agent is easier.

  Here, the Ti value is a value obtained from an equation of (viscosity of 2 rpm / viscosity of 20 rpm) based on the viscosity measured at 2 rpm and 20 rpm in accordance with JIS Z8803.

  The additive is prepared so that the adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio when the same amount of the first agent and the second agent are mixed. It is further contained in at least one of the agent and the second agent as necessary. Although an additive is not specifically limited, For example, a rheology control agent etc. can be used.

  Next, a tile repair method according to the present embodiment will be described with reference to FIGS. 1 and 2. The tile repairing method according to the present embodiment is a repairing method for a tile 14 disposed on the base wall 12 via an adhesive member 13 as shown in FIGS. 1 and 2. The base wall 12 is, for example, a cement board, the adhesive member 13 is, for example, mortar, and the tile 14 is, for example, brick, tile, stone, or the like.

  First, an injection 11 containing a first agent containing an adhesive component and a second agent containing a curing agent component, and at least one of the first agent and the second agent further containing a thixotropic agent is prepared. To do. In this step, when the same amount of the first agent and the second agent are mixed in the step of bonding the base wall 12 and the adhesive member 13 described later, the adhesive component, the curing agent component, and the thixotropic agent. And so that it becomes a predetermined ratio. In this step, prior to the step of bonding the base wall 12 and the adhesive member 13 at the construction site, the prepared first agent and second agent are filled in the containers, respectively.

  In this preparing step, the above-described injectable 11 before mixing is prepared. Specifically, in the step of preparing, the first agent and the second agent are prepared so that the viscosity of the first agent and the viscosity of the second agent are the same. Further, in the step of preparing, when the same amount of the first agent and the second agent are mixed in the step of bonding the base wall 12 and the adhesive member 13 described later, the Ti value is 6.5 or more and 8 The first agent and the second agent are prepared so as to be 0.0 or less, preferably 6.9 or more and 7.6 or less, more preferably 7.2 or more and 7.6 or less.

  Next, as shown in FIG. 2, the portion where the tile 14 is lifted, that is, the position of the gap 16 generated between the base wall 12 and the adhesive member 13 due to the adhesive member 13 floating from the base wall 12. Confirm.

  Next, in a state where the adhesive member 13 is lifted from the base wall 12, a hole portion 15 penetrating the adhesive member 13 is formed in the joint formed around the tile 14. When the joint material 17 is filled in the joint material, the hole 15 penetrating the joint material 17 and the adhesive member 13 is formed.

  Next, as shown in FIGS. 1 and 2, the base agent 12 and the adhesive member 13 are mixed by mixing the first agent and the second agent with the same weight and injecting the mixed injection 11 into the hole 15. And glue. In this step, the injection 11 is disposed in the gap 16 between the base wall 12 and the adhesive member 13 through the hole 15.

  This step is performed as follows, for example. Specifically, the same amount of the first agent and the second agent prepared in advance is mixed. More specifically, a predetermined amount is weighed from a container filled with the first agent, and a predetermined amount is weighed from a container filled with the second agent and mixed together. The predetermined amount is the same weight. Moreover, a 1st agent and a 2nd agent can be easily mixed as the viscosity of a 1st agent and the viscosity of a 2nd agent are the same. Thereby, the injection 11 can be produced. The mixing of the first agent and the second agent is performed immediately before injection. A predetermined pressure is applied to the injecting agent 11 thus mixed, and the mixture is injected from the hole 15. The injection method of the injection 11 is not particularly limited, but for example, a grease gun 18 or the like is used.

  As another injection method, the first agent and the second agent may be mixed and injected into the hole 15 as follows. Specifically, this is performed using an injection member that includes a first agent supply unit, a second agent supply unit, and a mixing unit. The first agent supply unit is supplied with the first agent from one end side to form a flow path for the first agent. A 2nd agent is supplied from the one end side, and the 2nd agent supply part forms the flow path of a 2nd agent. In the mixing unit, the other end of the first agent supply unit and the other end of the second agent supply unit are connected, and the first agent from the first agent supply unit and the second agent from the second agent supply unit are connected. Mixed. At the tip of the mixing part, an injection port for injecting the injection 11 in which the first agent and the second agent are mixed into the hole 15 is formed. As such an injection member, a static gun (not shown) etc. can be used, for example. The weight of the first agent supplied to the first agent supply part of the injection member is made equal to the weight of the second agent supplied to the second agent supply part, and a predetermined pressure is applied to the first and second agents to mix them. The first agent and the second agent are mixed in the mixing unit, and the mixed injection is discharged into the gap 16 from the injection port.

  As shown in FIG. 1, when the injection 11 is injected into the gap 16 between the base wall 12 and the adhesive member 13, the injection 11 is disposed in the gap 16. The injection agent 11 has a predetermined ratio of the adhesive component and the curing agent component by mixing the first agent and the second agent. The adhesive member 13 can be bonded.

  In this step, since the first agent and the second agent are mixed and the thixotropic agent becomes a predetermined ratio, the base wall 12 extends in a direction intersecting from the horizontal direction (for example, the vertical direction). Even so, sagging of the injection 11 downward in the vertical direction can be suppressed. In particular, the injection 11 in which the first agent and the second agent are prepared so that the Ti value becomes 6.5 or more and 8.0 or less when the same amount of the first agent and the second agent are mixed. When prepared, the dripping of the injection 11 can be effectively suppressed, and mixing of the first agent and the second agent is easy.

  Next, the hole 15 into which the injection agent 11 has been injected is filled with the joint material 17. Note that this step may be omitted.

  By performing the above-described steps, the base wall 12 and the adhesive member 13 of the tile 14 can be bonded by the injecting agent 11, so that the tile 14 in which the floating has occurred can be repaired.

  As described above, the tile repair method and the injection agent 11 according to the present embodiment are thixotropic to at least one of the first agent and the second agent prior to the step of bonding the base wall 12 and the adhesive member 13. When the first agent and the second agent having the same weight are mixed, the injection agent 11 is prepared so that the adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio. In other words, when the same amount of the first agent and the second agent are mixed, the first agent and the second agent are prepared in advance so as to have a composition satisfying the performance as an injecting agent. For this reason, at the construction site where the tile is repaired, it is only necessary to weigh the first agent and the second agent, so even if the first agent and the second agent are mistaken, The adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio. Thereby, the mixed injection 11 can obtain a predetermined performance stably. By injecting the injection 11 into the gap 16 between the base wall 12 and the adhesive member 13, the floating of the tile 14 can be repaired. Therefore, workability can be improved.

  In the tile repairing method of the present embodiment, the first agent and the second agent are injected into the hole 15 while being mixed. In other words, the first agent and the second agent before mixing are supplied separately to the injection member, the first agent and the second agent are mixed in the injection member, and the mixed injection is supplied to the injection member. Inject into the hole 15 from the inlet. Thereby, since the 1st agent and the 2nd agent can be mixed just before the hole 15 which should be inject | poured, hardening of the injection 11 can be suppressed until just before the injection | pouring to the hole 15. FIG. For this reason, since the injection 11 has a predetermined performance, the floating of the tile can be repaired by arranging the injection 11 in the gap 16 between the base wall 12 and the adhesive member 13. This is particularly effective when using an injecting agent having a high curing rate. In addition, since a member for mixing work such as a container for mixing the first agent and the second agent and a stirring member can be omitted, preparation work, cleaning work, cleaning work and the like of these members are omitted. You can also Therefore, workability can be further improved.

  Further, the tile repairing method and the injection agent 11 according to the present embodiment provide the hole 15 that penetrates the adhesive member 13 in the joint formed around the tile 14 in a state where the adhesive member 13 is lifted from the base wall 12. An injecting agent formed and mixed with the first agent and the second agent is injected into the hole 15. Compared with the method of removing a defective tile and pasting a new tile with an adhesive member, in this embodiment, it is not necessary to replace the tile 14, so that noise and the like due to the replacement of the tile 14 are prevented. it can. Further, compared to a method of drilling on the surface of the tile 14 and inserting a metal pin, in this embodiment, it is not necessary to insert the pin, so that cracking of the tile due to the insertion of the pin can be prevented.

  In addition, the tile repairing method and the infusate 11 of the present embodiment use the infusate 11 prepared in advance so that the viscosity of the first agent is the same as the viscosity of the second agent. Since the adhesive component and the hardener component are liquids having greatly different viscosities, and the thixotropic agent is a powder, the adhesive component, the hardener component, and the thixotropic agent are repaired at the construction site where the tile is repaired. Compared with the method of mixing, in this Embodiment, a 1st agent and a 2nd agent can be stirred easily. For this reason, the fall of the performance of the injection agent by insufficient stirring can be prevented.

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these.

[Example 1]
In Example 1, when the same amount of the first agent and the second agent are mixed, the injection components 1 to 4 prepared so that the adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio are used. The effect etc. were investigated.

(Injectant 1-4)
An epoxy resin (JBX-97SA manufactured by Aika Kogyo Co., Ltd.) as an adhesive component and silica powder as a thixotropic agent were mixed to prepare a first agent. A second agent was prepared by mixing an aliphatic amine (JBX-97SB manufactured by Aika Kogyo Co., Ltd.) as a curing agent component and silica powder as a thixotropic agent. When the same amounts of the first agent and the second agent were mixed, injections 1 to 4 were prepared so that the adhesive component, the curing agent component, and the thixotropic agent were in a predetermined ratio. This predetermined ratio is a ratio at which the performance assumed in advance as the injection agent is expressed. Further, when the same amount of the first agent and the second agent are mixed, the silica to be mixed so that the Ti value of the mixture (viscosity of 2 rpm / viscosity of 20 rpm) becomes the numerical value described in Table 1 below. Injections 1 to 4 were prepared by adjusting the weight of each powder.

(Test method)
A spacer having a thickness of 4 mm was disposed on an acrylic plate having a thickness of 5 mm as a base wall, a mortar as an adhesive member was formed on the spacer, and a plurality of tiles were disposed on the mortar. The spacer is for forming a gap, and the mortar was lifted from the acrylic plate by the spacer. In this state, a hole penetrating the mortar was formed in the joint formed around the tile using a drill having a diameter of 4 mm.

  Next, the 1st agent and 2nd agent of the injections 1-4 were measured so that weight ratio might be set to 1: 1, and it stirred by hand kneading. Thereby, the injections 1-4 by which the 1st agent and the 2nd agent were mixed were prepared. Table 1 shows the viscosities of the first agent and the second agent before mixing, and the viscosity of the injection (mixture) after mixing. The viscosity was measured according to JIS Z8803 with the rotation speed being 2 rpm and 20 rpm. Moreover, Ti value was calculated | required from the formula of (viscosity of 2 rpm / viscosity of 20 rpm). Moreover, the mixed injections 1-4 were scooped up with a spatula, and the sauce from the spatula was confirmed. The results are shown in Table 1 below. In Table 1, the occurrence of sagging was “none” if it was less than 5 mm, and the occurrence of sagging was “present” if it was 5 mm or more.

  Each of the injections 1 to 3 was filled in a grease gun and injected into the hole. The amount of the injection to be injected into the hole was about 1.7 g in one stroke. The stroke speed was 3-5 seconds / time. The temperature was 23 ° C. Under these conditions, the number of strokes of the injections 1 to 3 injected into one hole was set to 5 times, 10 times, and 15 times, respectively.

  Next, it was confirmed whether the acrylic board and the mortar were adhered by the injecting agents 1 to 3 injected at each stroke.

  In addition, it was confirmed whether or not the infusion of the infusate 1 to 3 injected in each stroke occurred after 60 minutes. The results are shown in Table 2 below and FIG. Each of FIGS. 3 (A) to 3 (C) shows injections 1 to 3 located in the gap, and the upper left injection has 15 strokes, and the right injection has 10 strokes. The lower left infusate has 5 strokes. Regarding “sagging” in Table 2, “existing” means that the distance extending downward from the center exceeds 10 mm with respect to the distance extending upward from the center where the injecting agent is injected, and “no” indicating that the distance is 10 mm or less. "

  Moreover, about the injection agents 1-3 inject | poured by each stroke, the area arrange | positioned in the clearance gap between an acrylic board and mortar was measured, and it was measured how much it was filled. The results are shown in Table 2 below. In Table 2, the “filling rate” is a value calculated by (area of injecting agent) / (area of two tiles).

(Evaluation results)
When the same amount of the first agent and the second agent are mixed, for the injections 1 to 3 prepared so that the adhesive component, the curing agent component, and the thixotropic agent are in a predetermined ratio, the acrylic plate and The mortar was bonded with high adhesiveness. For this reason, since the tile was repaired by mixing the 1st agent and the 2nd agent of the same weight, it turned out that workability can be improved. In addition, although the experiment which inject | pours the injection agent 4 into a hole is not performed, when the 1st agent and the 2nd agent of the same quantity are mixed, an adhesive agent component, a hardening | curing agent component, and a thixotropic agent are added. Since it prepared so that it might become a predetermined ratio, this inventor has acquired the knowledge that an acrylic board and mortar can be adhere | attached.

  Moreover, in the injection agents 1-4, since the 1st agent and the 2nd agent were prepared so that the viscosity of the 1st agent and the viscosity of the 2nd agent might become the same, mixing with the 1st agent and the 2nd agent Easy and mixing time was short.

  In addition, as shown in Table 1, when the same amount of the first agent and the second agent are mixed, the first agent and the second agent are adjusted so that the Ti value becomes 6.5 or more and 8.0 or less. Since the prepared injections 1 to 3 were free of dripping when scooped with a spatula, as shown in Table 2 and FIG. 3, dripping of the injections 1 to 3 can be suppressed when injected into the hole. It was.

  In the present embodiment, the description has been given by showing the injecting agents 1 to 4 having a predetermined Ti value. However, the present inventor explained that the Ti value is increased when the same amount of the first agent and the second agent are mixed. About each of the injection agent which prepared the 1st agent and the 2nd agent so that it might be 6.5 and 8.0, it was easy to control sauce and mixing with the 1st agent and the 2nd agent was easy I have confirmed that.

[Example 2]
In Example 2, using a static gun including a first agent supply unit, a second agent supply unit, and a mixing unit, while mixing the first agent and the second agent, the injections 1 to 3 of Example 1 Poured into the hole.

  Specifically, using a static gun having a tapered nozzle with an inner diameter of the tip (inlet) of 1.6 mm and a total length of 32 mm and a static gun having a nozzle with an inner diameter of 2.8 mm and a total length of 30 mm, Injecting agents 1 to 3 were injected into the same hole as 1 while mixing the first agent and the second agent. Specifically, the first agent supply unit is filled with each of the first agents 1 to 3 and the second agent supply unit is filled with each of the second agents 1 to 3 and the mixing unit The first agent and the second agent were mixed, and the mixed injection was injected into the hole. The single stroke of the infusate to be injected into the hole was about 4.5 g of infusate 1, about 6.2 g of infusate 2 and about 6.6 g of infusate 3. The temperature was 23 ° C. Under these conditions, for the injections 1 to 3, the number of strokes injected into one hole was set to 1, 3, 5 and 7 times, respectively.

(Test method)
In the same manner as in Example 1, it was confirmed whether the acrylic plate and the mortar were adhered by the injecting agents 1 to 3 injected at the respective strokes using the respective static guns. In addition, as in Example 1, it was confirmed whether or not sagging of the infusate occurred after 60 minutes for the infusibles 1 to 3 injected in each stroke.

(Test results)
By injecting the first agent and the second agent into the hole while mixing them, it was possible to prevent the injection agent from being cured before being injected into the hole, so that the acrylic plate and the mortar are highly adhesive. And had a bond. For this reason, it turned out that a tile can be repaired and workability can be improved by inject | pouring into a hole part, mixing a 1st agent and a 2nd agent.

  Also, by this injection method, the first agent and the second agent are prepared so that the Ti value becomes 6.5 or more and 8.0 or less when the same amounts of the first agent and the second agent are mixed. It was found that the injected agents 1 to 3 can effectively suppress dripping.
