Description

  TECHNICAL FIELD The present invention relates to a slip-proof floor construction method and a slip-proof floor, and more particularly to a slip-proof floor construction method in which an appropriate aggregate is dispersed in a thermosetting resin and the slip-proof floor.

Conventionally, for example, in an antiskid floor constructed on a base such as a road surface of a parking lot, an appropriate aggregate is mixed with a polyurethane-based resin (see Patent Document 1). . The surface of the anti-slip floor has an uneven shape due to the mixed aggregate, and an appropriate frictional force is applied by the uneven shape to prevent a vehicle tire or the like from slipping. In such a non-slip floor, it was constructed by appropriately applying a polyurethane-based resin and spraying an appropriate aggregate during the curing of the applied polyurethane-based resin.
JP 2003-120009 A

  However, the anti-skid floor constructed as described above is composed of polyurethane resin, which is an organic material, and aggregate, which is an inorganic material. Therefore, the adhesive strength between the polyurethane resin and the aggregate was weak. As a result, in such an antiskid floor, when it receives an external load such as friction, impact, and wear, it is mixed with the polyurethane resin by the external load and integrated with the polyurethane resin. The aggregate was easily peeled from the polyurethane resin.

  For example, a slip-proof floor constructed on the road surface of a parking lot is more susceptible to an external load at a location where the amount of traffic such as a vehicle is larger. It was happening. If the aggregate is peeled off from the polyurethane resin in this way, the anti-slip property that has been obtained until then is lost. In addition, the non-slip floor from which the aggregate has been peeled also leads to the exposure of the foundation serving as the foundation, thereby causing a problem of promoting the deterioration of the foundation.

  The present invention has been made in view of such circumstances, and enhances the mutual adhesive force between the resin and the aggregate mixed in the resin, and the aggregate is separated from the resin over a long period of time. Accordingly, it is an object of the present invention to provide a slip-proof floor construction method and a slip-proof floor capable of maintaining the slip-proof performance over a long period of time.

In order to solve the above-described problems, the present invention provides a method for constructing a non-slip floor and a non-slip floor according to the following means.
That is, the invention of the non-slip floor construction method according to claim 1 is a first resin material in which a resin material such as polyurethane resin, polyurea resin, epoxy resin, unsaturated polyester resin, vinyl ester resin, methyl methacrylate resin is applied. At least a part of the aggregate treated with a silane coupling agent having an outer surface having a functional group such as an epoxy group, an amino group, or a vinyl group is embedded in the applied resin material in the course of curing. And an aggregate spraying step of spraying.

  In the non-slip floor construction method according to the present invention, the first resin material application step and the aggregate spraying step are included. In the first resin material application step, a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin, which is a main agent, is applied. Further, in the aggregate spraying step, the aggregate is sprayed so that at least a part of the resin material is buried during the curing of the resin material. Here, the aggregate is treated so that its outer surface is coated with a silane coupling agent having a functional group such as an epoxy group, an amino group, or a vinyl group.

  This silane coupling agent has the property of being easily bonded to resin materials such as polyurethane resins, polyurea resins, epoxy resins, unsaturated polyester resins, vinyl ester resins, and methyl methacrylate resins. As a result, the adhesive strength between the aggregate coated with the silane coupling agent having such a functional group and these resin materials is improved. Therefore, in this anti-skid floor, the aggregate is hardly peeled off from the resin material, and the anti-skid floor capable of suitably maintaining the anti-slip performance over a long period of time can be constructed. In addition, the amount embedded in the resin material of the aggregate can be selected as an appropriate amount such as a part, a half, or the whole. However, the amount of the aggregate embedded in the resin material is preferably about half that the aggregate is preferably exposed from the viewpoint of the anti-slip performance of the anti-slip floor and the adhesive strength between the aggregate and the resin material. It is said.

  The invention of the non-slip floor construction method according to claim 2 is a first resin material application step of applying a resin material such as polyurethane resin, polyurea resin, epoxy resin, unsaturated polyester resin, vinyl ester resin, methyl methacrylate resin, etc. And the applied resin material in the middle of curing so that at least a part of the aggregate is treated with a silane coupling agent having an outer surface having a functional group such as an epoxy group, an amino group, or a vinyl group. And a second resin material application step of applying a new resin material of the same quality as the resin material on the resin material on which the aggregate has been dispersed.

  In the non-slip floor construction method according to the present invention, the first resin material application step, the aggregate spraying step, and the second resin material application step are included. In the first resin material application step, a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin, which is a main agent, is applied. Further, in the aggregate spraying step, the aggregate is sprayed so that at least a part of the resin material is buried during the curing of the resin material. Further, in the second resin material application step, after the aggregate spraying step, a resin material having the same quality as the resin material applied in the first resin material application step is further dispersed in the aggregate. Apply from above.

  Here, the aggregate is treated so that its outer surface is coated with a silane coupling agent having a functional group such as an epoxy group, an amino group, or a vinyl group. As described above, the silane coupling agent has a property of being easily adhered to a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin. As a result, the adhesive strength between the aggregate coated with the silane coupling agent having such a functional group and these resin materials is improved. The adhesive strength of the applied resin material and aggregate is preferably improved in any of the first resin material application process and the second resin material application process.

  Moreover, since the resin material applied in the first resin material application step and the second resin material application step is made of the same quality, the applied resins are easily bonded. Thereby, the resin materials applied in the first resin material application step and the second resin material application step are likely to be integrated. That is, the aggregate is suitably embedded in the resin material, and the aggregate and the resin material are preferably firmly bonded. Therefore, in this anti-skid floor, the aggregate is difficult to peel off from the resin material, and unlike the invention according to claim 1, the resin material is covered so as to cover the aggregate without exposing it. Since it is applied, it is possible to construct an antiskid floor that can suitably maintain antiskid performance over a long period of time.

  Further, the invention of the method for constructing a non-slip floor according to claim 3 is the method for constructing a non-slip floor according to claim 1 or 2, wherein the resin in the first resin material application step is provided on a waterproof layer provided in advance. Material is applied.

  In the construction method of the non-slip floor according to the present invention, the anti-skid floor constructed as described above is constructed on the waterproof layer provided in advance. That is, this waterproof floor is provided with a waterproof layer. Thus, by providing a waterproof layer, waterproofing is imparted to the anti-slip floor. Therefore, it is possible to construct a non-slip floor that can suitably prevent inundation of the construction site and avoid problems such as building water leakage.

  Further, the invention of the non-slip floor according to claim 4 is a resin material such as polyurethane resin, polyurea resin, epoxy resin, unsaturated polyester resin, vinyl ester resin, methyl methacrylate resin, and the outer surface is epoxy group, amino group, Or the aggregate processed by the silane coupling agent which has functional groups, such as a vinyl group, is filled with at least one part, It is characterized by the above-mentioned.

  In the non-slip floor according to the present invention, at least a part thereof is buried in a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin as a main agent. Aggregate made is mixed. Here, the aggregate is treated so that its outer surface is coated with a silane coupling agent having a functional group such as an epoxy group, an amino group, or a vinyl group. As described above, the silane coupling agent has a property of being easily adhered to a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin. Accordingly, the adhesive strength between the aggregate and the resin material to which the silane coupling agent having such a functional group is applied is improved.

  Furthermore, since the aggregate is at least partially embedded in the resin material, the aggregate and the resin material are preferably firmly bonded. Therefore, in this anti-skid floor, the aggregate is hardly peeled off from the resin material, and the anti-skid floor capable of suitably maintaining the anti-slip performance over a long period of time can be constructed. In addition, the amount embedded in the resin material of the aggregate can be selected as an appropriate amount such as a part, a half, or the whole. However, the amount of the aggregate embedded in the resin material is preferably about half that the aggregate is preferably exposed from the viewpoint of the anti-slip performance of the anti-slip floor and the adhesive strength between the aggregate and the resin material. It is said.

  According to a fifth aspect of the present invention, in the antiskid floor according to the fourth aspect, a waterproof layer is provided on the lower side of the resin material.

  In the non-slip floor according to the present invention, a waterproof layer is provided on the lower side. That is, this waterproof floor is provided with a waterproof layer. Thus, by providing a waterproof layer, waterproofing is imparted to the anti-slip floor. Therefore, it is possible to provide a non-slip floor that can suitably prevent inundation of the construction site and avoid problems such as building water leakage.

  According to the construction method and the anti-skid floor of the present invention, the adhesive force between the resin forming the anti-slip layer and the mixed aggregate is enhanced, and the aggregate is used for a long period of time. It is difficult to peel from the lever resin. As a result, an anti-skid floor capable of having anti-slip performance over a long period of time is obtained.

That is, as will be described in detail later, a primer layer 10 formed by applying a primer and a waterproof layer 20 formed on the primer layer 10 are formed on the upper surface of the base B serving as a base. An anti-slip layer 30 is formed on the waterproof layer 20. Further, a top coat layer 50 made of an appropriate resin or the like is formed on the top surface of the anti-slip layer 30 for the purpose of covering and protecting the anti-slip layer 30 and good appearance.

  The anti-slip layer 30 is mainly composed of a polyurethane-based resin, and is composed of the resin 31 and an aggregate 41 mixed in the resin. The aggregate 41 is mixed so as to be buried in the resin 31. In addition, the outer periphery of this aggregate 41 is processed so that it may be apply | coated with the silane coupling agent which has functional groups, such as an epoxy group, an amino group, and a vinyl group. As the main agent, as will be described later, an appropriate resin composed of a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, a methyl methacrylate resin, and the like can be selected. From this point of view, any resin having thermosetting properties is preferred.

  Next, a construction method for forming the above-described antiskid floor 1 will be described with reference to FIGS. 2 and 3. In addition, as for the construction method of this slip-proof floor, each process advances in order of FIG. 2 (a), FIG.2 (b), FIG.3 (a), FIG.3 (b), FIG.3 (c), and FIG. It has become a thing. 2A shows a primer coating process that is a part of the waterproof layer forming process, FIG. 2B shows a waterproof film forming process that is a part of the waterproof layer forming process, and FIG. a) shows the 1st resin material application | coating process used as a part of anti-slip layer formation process, FIG.3 (b) shows the aggregate spraying process used as a part of anti-slip layer formation process, FIG.3 (c) Shows the 2nd resin material application | coating process made into a part of slip prevention layer formation process.

In this primer coating process, an adhesive force is applied so that the waterproof layer 20 formed in the waterproof film forming process described below and the surface B1 of the base B are suitably bonded. In order to secure, a primer is applied to the base B. Specifically, an appropriate epoxy primer is uniformly applied to the upper surface B1 of the substrate B in an appropriate amount by a roller. In addition, as a method of this application | coating, the said primer may be sprayed and apply | coated to the base | substrate B with a spray gun, and it may apply with a brush. In this way, the primer layer 10 is formed on the upper surface B1 of the base B as shown in FIG.

  Then, after the primer application process, the process proceeds to a waterproof film forming process. This waterproof film forming step is a step of forming a waterproof layer 20 on the primer layer 10 as shown in FIG. Specifically, for example, a base material B on which the primer layer 10 is formed is made of polyurethane-based material using a two-component collision mixing type spray coating apparatus (two-component collision mixer) equipped with a high-pressure spray gun. The waterproof layer 20 is formed by spraying and applying toward the surface. Examples of the polyurethane-based material include a solvent-free ultra-fast curing two-component polyurethane system composed of two solutions of a solvent-free polyisocyanate prepolymer and a solvent-free polyol (which may contain a solvent-free polyamine in some cases). Resin is preferable in that it quickly reacts to form the waterproof layer 30. Moreover, about the thickness of the waterproof layer 20 formed, an appropriate thickness can be selected. As described above, since the primer is applied to the upper surface B1 of the substrate B, the waterproof layer 20 is suitably bonded to the upper surface B1 of the substrate B.

  In the above description, the waterproof layer forming step includes a primer applying step for forming the primer layer 10 on the upper surface B1 of the base B and a waterproof film forming step for forming the waterproof layer 20 on the primer layer 10. However, the primer coating process may be omitted and the waterproof layer forming process may be performed only by the waterproof film forming process. In this case, as shown in FIG. 1, the primer layer 10 described above is also omitted.

  Moreover, when forming this waterproof layer 20, it is not limited to this polyurethane-type resin, You may use the polyurea-type resin which can exhibit the outstanding waterproof performance. In the above description, the waterproof layer 20 is formed by mixing two liquids (two liquid mixing type) using a two-component collision mixing type spray coating apparatus equipped with a high-pressure spray gun. However, without being limited thereto, the waterproof layer 20 may be formed by hand-coating a one-component polyurethane material or polyurea material. In this case, the initial curing time is preferably 5 minutes to 24 hours.

  Furthermore, the polyurethane resin is preferably a two-component mixed type from the viewpoint of being less affected by humidity and easy to control the curing time. In particular, at least one selected from a main component mainly composed of polyisocyanate, polyol, polyamine and water is used. A polyurethane resin mixed with a curing agent as a main component is preferable. Further, the polyisocyanate is not particularly limited. For example, diphenylmethane-4,4′-diisocyanate (MDI), carbodiimide-modified diphenylmethane diisocyanate (liquid MDI), polymethylene polyphenyl isocyanate (crude MDI), 2,4-tolylene Low molecular weight isocyanate compounds such as isocyanate (2,4-TDI), 2,6-tolylene diisocyanate (2,6-TDI), xylylene diisocyanate (XDI), hexamethylene diisocyanate and the like can be mentioned. Moreover, the isocyanate group terminal prepolymer which modified | denatured the said isocyanate compound, a buret-modified body, etc. are mentioned. In addition, these may be used independently or may use 2 or more types together.

  In the case where the waterproof layer 20 is formed of a two-component mixed spray type polyurethane resin, the polyisocyanate is preferably MDI, liquid MDI or a modified product thereof, an isocyanate group-terminated prepolymer, or the like. In the case of a polyurethane resin with a hand coating type, 2,4-TDI, 2,6-TDI, MDI, liquid MDI or a modified product thereof, an isocyanate group-terminated prepolymer, and the like are preferable. In addition, additives such as a plasticizer, a curing catalyst, a filler, an antioxidant, a flame retardant, a stabilizer, an ultraviolet absorber, a surfactant, and a coloring pigment are added to the resin as necessary. It may be.

  Further, as the curing agent, it is preferable to use at least one selected from polyol, polyamine and water, but it is particularly preferable to use only polyamine or a mixture of polyamine and polyol. The polyol is not particularly limited as long as it has two or more hydroxyl groups, and examples thereof include polyether polyols, polyester polyols, general polyols such as polytetramethylene glycol, and flame retardant polyols such as phosphorus-containing polyols. . These may be used alone or in combination of two or more. Moreover, although it does not specifically limit as said polyamine, An aromatic polyamine, an aliphatic polyamine, etc. are mentioned. Specifically, diethyltoluenediamine, dialkyl-4,4′-methylenedianiline, tetraalkyl-4,4′-methylenedianiline, 4,4′-methylenebis (2-chloroaniline), bismethylthiotoluenediamine, Examples include polyoxyalkylene diamine, metaxylylene diamine, ethylene diamine, and isophorone diamine. These may be used alone or in combination of two or more.

Any one of thermosetting resins such as methyl methacrylate resin may be used. When a resin such as polyurethane-based resin or polyurea-based resin is used as the main component of the anti-slip layer 30, it is advantageous in that a waterproof effect is imparted, and without using an appropriate primer, It is also advantageous in that it is suitably bonded to the waterproof layer 20. Moreover, as such resin, from the viewpoint of workability, a thermosetting resin that cures when heated should be selected.

As described above, the top coat 50 is applied for the purpose of protecting the anti-slip layer 30 and improving the appearance of the anti-slip floor 1. Specifically, the top coat 50 is formed by selecting a material made of, for example, acrylic urethane resin and applying it with a roller.

  In the above-described anti-slip layer 30, as shown in FIG. 4A, the aggregate 41 mixed in the anti-slip layer 30 is cured by the resin materials 31 a and 35 a serving as the main agent being cured. In such a case, it is configured not to be exposed to the outside. However, the present invention is not limited to this, and part of the dispersed aggregate 41 may be exposed to the outside to form the anti-slip layer 30. Specifically, the anti-slip layer 30 may be formed by omitting the second resin material application step in the resin material application step. When the anti-slip layer 30 is formed by omitting the second resin material application step, a part of the aggregate 41 is exposed to the outside to form the anti-slip layer 30 as shown in FIG. 4B. Is done. In the case where the second resin material 35a is applied to form the resin 31, the specification is “with a sealing layer” in a later test. On the other hand, when the second resin material 35a is not applied, that is, when the resin 31 is formed up to the aggregate spraying process without the second resin material process, in a later test, “no sealing layer” It is said that.

  The following tests were performed on the strength of the adhesive force between the resin 31 and the aggregate 41 with respect to the anti-slip floor 1 formed as described above. In preparing the treatment liquid, a silane coupling agent having an epoxy group (Shin-Etsu Chemical Co., Ltd., trade name: KBM-403, chemical name: 3-glycidoxypropyltrimethoxysilane) and amino are used as silane coupling agents. A silane coupling agent having a group (Shin-Etsu Chemical Co., Ltd., trade name: KBM-603, chemical name: N-2 (aminoethyl) 3-aminopropyltrimethoxysilane) was used. When preparing the concentration of the silane coupling agent having an epoxy group, as described above, it is prepared by diluting with a 1% aqueous acetic acid solution to prepare the concentration of the silane coupling agent having an amino group. In this case, it is prepared by diluting with water as described above.

  Using the treatment liquid thus prepared, the aggregate 41 was treated as follows, and test pieces 1 to 4 were produced. That is, for the test pieces 1 to 4, the drying time after the application of the first resin material 31a was set to about 10 minutes, and the aggregate 41 was sprayed after the drying time of about 10 minutes passed. Is. In preparing the test pieces 1 to 4, using the treatment liquid prepared so that the concentration of the silane coupling agent containing the above-described epoxy group, amino group, vinyl group and the like is 1% by weight, The aggregate 41 is treated in advance by either the dry method (Example 3) or the wet method (Example 1).

  Specifically, as shown in Table 1 below, the test piece 1 and the test piece 2 are diluted with a 1% strength aqueous acetic acid solution so that the concentration of the silane coupling agent containing an epoxy group is 1% by weight. Using the treated liquid, the aggregate 41 is processed by either the dry method (Example 3) or the wet method (Example 1). In addition, the test piece 3 and the test piece 4 are prepared by using the above-described dry method (Example 3) or the treatment solution diluted with water so that the concentration of the amino group-containing silane coupling agent is 1% by weight. The aggregate 41 is processed by any one of the wet methods (Example 1). When the aggregate 41 is processed by the dry method, the aggregate 41 is 100% by weight, whereas the treatment liquid is added at 1% by weight.

  The aggregate 41 obtained in this way is sprayed on the polyurethane resin material 31a that has been applied for about 10 minutes, and then the polyurethane resin material 31a is cured to form the polyurethane resin 31. Each of the pieces 1-4 was produced. In addition, in this test piece 1-4, the aggregate 41 is spread | dispersed so that the weight ratio of the polyurethane-type resin 31 and the aggregate 41 may be set to 1: 2.5. The polyurethane-based resin material 31a is poured into a mold formed with a width of 20 mm, a thickness of 10 mm, and a length of 150 mm even in the test pieces 5 to 21 described later including the test pieces 1 to 4. Formed.

  And the intensity | strength of the adhesive force of the aggregate 41 and the polyurethane-type resin 31 was evaluated by the bending test (JISK7055 conformity) using these test pieces 1-4. This bending test is a bending test performed with three fulcrums. The distance between the fulcrums is 100 mm, and the compression speed is 5 mm / min. Moreover, when comparing the strength of the adhesive strength of these test pieces 1 to 4, the comparison piece 1 in which the aggregate 41 that has not been treated as described above is also tested. The test results are shown in Table 1 below.

  As shown in Table 1, it was found that the test pieces 1 to 4 had a strength higher than that of the comparative piece 1 when the breaking strength was 220 N. Moreover, even if it existed in the displacement amount, compared with the said comparison piece 1 being 4.8 mm, it turned out that the test pieces 1-4 become a displacement amount beyond this. Accordingly, it has been found that the aggregate 41 is less likely to be peeled off from the polyurethane resin 31 than in the past due to the increase in the strength at the time of breakage and the increase in the amount of displacement. That is, it has been found that the aggregate 41 has an increased adhesive force with the polyurethane resin 31 as compared with the conventional case.

  Next, in the case where the drying time after application of the first resin material 31a is set to about 6 to 8 hours, as described above, the concentration of the amino group-containing silane coupling agent is 1 to 50% by weight. Test pieces 5 to 9 are produced by spraying the aggregate 41 processed by the dry method (Example 3) using the processing solution prepared as described above.

  Specifically, as shown in Table 2 below, the test pieces 5 to 9 have an amino group-containing silane coupling agent concentration of 1% by weight in the test piece 5 and in the test piece 6. 5% by weight, 10% by weight for the test piece 7, 20% by weight for the test piece 8, and 50% by weight for the test piece 9, a treatment solution diluted with water. Is used to process the aggregate 41 by the dry method (Example 3). The aggregate 41 obtained in this manner is sprayed as described above on the polyurethane resin material 31a that has been applied for about 6 to 8 hours, and then the polyurethane resin material 31a is cured to form polyurethane. As the resin 31, each of the test pieces 5 to 9 was produced. And the strength of the adhesive force of the aggregate 41 and the polyurethane-type resin 31 was evaluated by the bending test (JISK7055 conformity) similarly to the above-mentioned test using these test pieces 5-9. In addition, in comparing the strength of the adhesive strength of these test pieces 1 to 4, the comparison piece 2 in which the untreated aggregate 41 is dispersed is also tested. The test results were as shown in Table 2 below.

  As shown in Table 2, it was found that the test pieces 5 to 9 had higher strength than that of the comparative piece 2 when the strength at break was 198N. Moreover, even if it existed in the displacement amount, compared with the said comparison piece 2 being 4.1 mm, it turned out that the test pieces 5-8 except the test piece 9 become displacement amount beyond this. Accordingly, it has been found that the aggregate 41 is less likely to be peeled off from the polyurethane resin 31 than in the past due to the increase in the strength at the time of breakage and the increase in the amount of displacement. That is, it has been found that the adhesive force between the aggregate 41 and the polyurethane resin 31 is increased.

Next, the strength of the adhesive force between the aggregate 41 and the polyurethane resin 31 was evaluated by a stationary test.
The stationary test will be described. First, a front wheel of a passenger car is placed on the obtained test piece. Then, the tire is turned back to the right and left a predetermined number of times on the upper surface of the test piece so that the tire as the front wheel rubs the upper surface of the test piece. Thereafter, it is observed how much the aggregate 41 constituting the anti-slip layer 30 is removed from the resin 31 or dropped, and the strength of the adhesive force between the aggregate 41 and the polyurethane resin 31 is evaluated. Is. In addition, the said test piece is constructed | assembled on a concrete board (length 300mm, width 300mm, thickness 50-60mm) like embodiment mentioned above based on the conditions demonstrated below (refer Table 3 and Table 4). The periphery of the construction is fixed with a metal frame.

  That is, the aggregate 41 is processed by the above-described dry method (Example 3) using a processing solution prepared so that the concentration of the amino group-containing silane coupling agent is 1 to 50% by weight. And the aggregate 41 was spread | dispersed on what the drying time after application | coating of the said 1st resin material 31a was set to about 10 minutes, and the test pieces 10-19 were produced. The test pieces 10 to 14 have a specification of “there is a sealing layer” in which the second resin material 35a is applied to form the resin 31 in the second resin material process. In the case of Nos. 15 to 19, the second resin material process is omitted, and the second resin material 35a is not applied and the resin 31 is formed so as to be “no sealing layer”.

  Further, in this stationary test, the concentration of the silane coupling agent containing an amino group as described above is set so that the drying time after application of the first resin material 31a is set to about 10 minutes. Test pieces 10 to 19 are produced by spraying the aggregate 41 processed by the dry method (Example 3) using a treatment liquid prepared to be 1 to 50% by weight.

  Specifically, as shown in Tables 3 and 4 below, the test pieces 10 to 19 are 1 when the concentration of the amino group-containing silane coupling agent is in the test pieces 10 and 15. 5% for test piece 6 and test piece 16, 10% for test piece 7 and test piece 17, 20% for test piece 8 and test piece 18, test piece 9. In the test piece 19, the aggregate 41 is treated by the dry method (Example 3) using a treatment liquid diluted with water so as to be 50% by weight. The aggregate 41 obtained in this way is sprayed onto the polyurethane resin material 31a that has been applied for about 10 minutes as described above, and then the polyurethane resin material 31a is cured to make the polyurethane resin 31. As above, each of the test pieces 10 to 19 was prepared. Regarding the test pieces 10 to 14, when the aggregate 41 is processed by the dry method, the aggregate 41 is 100% by weight, whereas the treatment liquid is 1% by weight. Is inserted. Further, regarding the test pieces 15 to 19, when the aggregate 41 is processed by the dry method, the aggregate 41 is 100% by weight, but different amounts of the processing liquid are supplied. That is, the test piece 15 is charged with 1 wt% treatment liquid, the test piece 16 is loaded with 5 wt% treatment liquid, and the test piece 17 is loaded with 10 wt% treatment liquid. The test piece 18 is charged with 20% by weight of processing solution, and the test piece 19 is charged with 50% by weight of processing solution.

Then, using these test pieces 10 to 19, the strength of the adhesive force between the aggregate 41 and the polyurethane resin 31 was evaluated by the above-described stationary test, similarly to the above-described test. In addition, when comparing the strength of the adhesive strength of these test pieces 10 to 19, the comparison piece 3 and the comparison piece 4 configured by spraying an untreated aggregate 41 are also tested. The test results were as shown in Table 3 and Table 4 below.

  As shown in Table 3, the removal and removal of the aggregate 41 of the comparative piece 3 were less than the removal and removal of the aggregate 41 of the test pieces 10 to 14 as compared with this. It became less. Moreover, as shown in Table 4, the removal and dropping of the aggregate 41 of the test pieces 15 to 17 are less than the removal and dropping of the aggregate 41 of the comparative piece 4 as compared to the large amount. As a result, the aggregate 41 of the test pieces 18 and 19 was removed and dropped slightly.

  Therefore, as can be seen from Table 4, when the anti-slip layer 30 is formed using the aggregate 41 treated with the treatment liquid, the anti-slip layer 30 is formed using the untreated aggregate 41. In comparison, it was found that the aggregate 41 was less removed and dropped, and the adhesive force between the aggregate 41 and the polyurethane resin 31 was increased. That is, it was found that the aggregate 41 was less likely to be peeled off from the polyurethane resin 31 than in the past.

  Furthermore, as can be seen from the fact that the aggregate 41 of the test specimens 15 to 17 is less removed and dropped, the aggregate 41 is treated with a treatment liquid in which the concentration of the silane coupling agent is 1 to 10% by weight. In this case, the aggregate 41 is less likely to be removed and dropped. It was found that the adhesive force between the aggregate 41 and the polyurethane resin 31 was preferably increased, and the aggregate 41 was less likely to be peeled off from the polyurethane resin 31 than in the past. In addition, when the concentration of the silane coupling agent in the treatment liquid is 1% by weight as in the test piece 15, the adhesive force between the aggregate 41 and the polyurethane resin 31 is preferably increased. It is very preferable because it can eliminate waste of raw materials.

  In the slip-proof floor construction method described above and the slip-proof floor 1 formed by the construction method, the slip-proof layer 30 in which the aggregate 41 is mixed is formed on the waterproof layer 20 formed on the base B. It is formed. The anti-slip layer 30 is composed of a main agent and an aggregate 41 partially or entirely embedded in the main agent. The main agent is made of a resin 31 such as a polyurethane resin or a polyurea resin, and an appropriate one can be selected for the aggregate 41. For example, the sand is finely crushed. Natural oxalic acid such as basalt and river sand can be selected, and it can be replaced by ceramics. Here, the outer surface of the aggregate 41 is treated so as to be applied with a silane coupling agent having a functional group such as an epoxy group, an amino group, or a vinyl group, and a coating film 42 made of the silane coupling agent is formed. The Rukoto.

  Further, in the aggregate 41, an appropriate amount can be selected. From the viewpoint of the anti-slip performance of the anti-slip floor 1 and the adhesive strength between the aggregate 41 and the resin 31, the aggregate 41 is It is preferable that the aggregate 41 is embedded so as to be approximately half exposed from the resin 31, that is, approximately half is embedded in the resin 31.

At this time, in the silane coupling agent having a functional group such as an epoxy group, an amino group, or a vinyl group described above,
Since it is considered to be well bonded to resin materials such as polyurethane resins, polyurea resins, epoxy resins, unsaturated polyester resins, vinyl ester resins, methyl methacrylate resins, silane coupling agents having such functional groups The applied aggregate is suitably bonded to a resin material such as a polyurethane resin, a polyurea resin, an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, or a methyl methacrylate resin. That is, the mutual adhesive strength is improved. Therefore, the aggregate mixed in the main agent of the anti-slip layer is preferably bonded to the main agent forming the anti-slip layer, and the aggregate is difficult to peel from the main agent over a long period of time. An anti-slip layer capable of maintaining anti-slip performance over the entire area is formed. As a result, a slip-proof floor capable of maintaining the slip-proof performance over a long period of time is obtained.

Note that the present invention is not limited to the above-described embodiment, and appropriate selections can be made without departing from the spirit of the present invention.
For example, in the embodiment described above, the waterproof layer 20 is formed by spraying a two-component mixed polyurethane resin, but the one-component polyurethane is not limited to this. The waterproof layer 20 may be formed by spraying a resin or a polyurea resin.
Further, the waterproof layer 20 is provided on the anti-slip floor 1 for the purpose of imparting a waterproof effect to the anti-skid floor 1, but the waterproof layer 20 may be omitted if appropriate. It does not depart from the spirit of the invention.
