Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-based paint for floors and a floor structure, and more particularly to a paint used for floor maintenance.

[0002]

2. Description of the Related Art Conventionally, floor materials for houses, offices, hospitals, department stores, gymnasiums, factories and the like include resin materials such as vinyl chloride, ceramic materials such as tiles, stone materials such as marble, and wood materials such as flooring. And concrete-based materials such as mortar and the like. These floor materials can be used as they are, but a polisher such as wax is applied to the floor surface. Thereby, deterioration of the floor surface can be prevented and durability can be improved. In addition, cleaning can be facilitated, and the appearance can be improved by giving glossiness.

[0003]

However, the above-mentioned conventional polishing agents have the following problems. That is, the application of the polishing agent is a routine maintenance work for the floor material and needs to be performed periodically. If the polishing agent is applied repeatedly, dust often enters the coated surface of the coating, and once the dust has entered, it can be cleaned with a vacuum cleaner or the like.
It is difficult to remove even by wiping with water, chemical cleaning of a cleaning agent such as thinner, mechanical cleaning of a buff or the like. For this reason, prior to the application of the polishing agent, a stripping operation using a stripping agent such as carbitol is performed to remove dirt that has penetrated with the coating film of the polishing agent.

[0004] However, the peeling operation is extremely troublesome.
Further, since the release agent is generally strongly acidic or strongly alkaline, the floor material itself may be deteriorated. Moreover,
It is difficult to completely remove the coating film to which dust adheres even by a peeling operation. Further, when walking on the coating film, the coating film layer is extended and becomes thin.

[0005] For this reason, the portion where the walking load is large may be thin, and the portion where the walking load is small may be thick, which may make the appearance unsightly. In particular, in places where an unspecified number of people frequently walk, such as restaurants, department stores, banks, etc., it was often the case that the floor material was left exposed and the deterioration of the floor material was left as it was without applying a polishing agent. .

In order to solve such a problem, Japanese Patent Application Laid-Open No. 4-65472 proposes improvement of a polishing agent. However, polishes must still be applied, and maintenance work on the floor is
It is complicated.

[0007] The present invention has the above-mentioned conventional problems. The water-based paint for floor and the floor paint which can easily perform maintenance work on the floor, and have a high effect of preventing the floor from slipping and can improve the appearance of the floor. It is intended to provide a surface structure.

[0008]

According to the first aspect of the present invention, there is provided a water-based paint for a floor applied to a floor, wherein the water-based paint for a floor contains an aqueous resin, a solvent, and an anti-slip agent, In addition, the content of the anti-slip agent is from 10 to 100 parts by weight based on 100 parts by weight of the aqueous resin.

In the present invention, the aqueous resin is a water-soluble resin component, and may contain a curing agent as described later. As such an aqueous resin, for example, an epoxy resin and / or an acrylic resin can be used. Further, it may contain an acrylic urethane resin, a urethane resin, a vinyl acetate resin, or the like.

[0010] Among these aqueous resins, Adeka Resin (Asahi Denka Kogyo Co., Ltd.)
Becko Pox (manufactured by Hoechst Japan K.K.),
It is preferable to use CAT-EPK (manufactured by Toyo Morton Co., Ltd.) or the like.

As the acrylic resin, polyzol (manufactured by Showa Polymer Co., Ltd.), acronal (manufactured by Mitsubishi Yuka Birdish Co., Ltd.), and neoacryl (Zeneca Co., Ltd.)
Manufactured by Dainippon Ink and Chemicals, Inc.
Acryl (Nippon Shokubai Co., Ltd.), Arolon (Nippon Shokubai Co., Ltd.), Phthalkid (Hitachi Chemical Industry Co., Ltd.), Movinyl (Hoechst Gosei Co., Ltd.), Armatex (Mitsui East) Pressure Chemical Co., Ltd.), Tokuril (Toyo Ink Mfg. Co., Ltd.), Riocryl (Toyo Ink Mfg. Co., Ltd.) and the like are preferably used. As the acrylic urethane-based resin, Neopack (Zeneca Corporation)
Is preferred.

As the urethane resin, Adekabon Titer HUX series (manufactured by Asahi Denka Kogyo Co., Ltd.), Permusen (manufactured by Zeneca Corporation), Neoretz (Zeneca Corporation)
), Spensol (Dainippon Ink & Chemicals, Inc.)
Manufactured by Dainippon Ink and Chemicals, Inc.)
It is preferable to use Neotan (manufactured by Toagosei Chemical Industry Co., Ltd.), Daotane (manufactured by Hoechst Japan Co., Ltd.), Olestar (manufactured by Mitsui Toatsu Chemical Co., Ltd.), or the like.

As the vinyl acetate resin, it is preferable to use polysol (manufactured by Showa Polymer Co., Ltd.) or movinyl (manufactured by Hoechst Gosei Co., Ltd.). The above various aqueous resins can be used alone or as a mixture.

[0014] The aqueous resin component may contain a curing agent. Examples of the curing agent include general curing agents used for resins, for example, epomate (made by Yuka Shell Co., Ltd.), cure amine (made by Ihara Chemical Co., Ltd.), and Beccopox Special Hardener (used for epoxy resin). Amines such as Hoechst Japan Co., Ltd., MF-40 (Toyo Morton Co., Ltd.), or Aquanate (Nippon Polyurethane Industry Co., Ltd.), Desmodur (Sumitomo Bayer Urethane Co., Ltd.), etc. A room temperature curing agent such as an isocyanate can be used.

Next, the solvent is a liquid capable of dissolving the aqueous resin. As the solvent, for example, water can be used.

Next, the above-mentioned anti-slip agent is a particle which does not dissolve or is hardly dissolved in a solvent. Examples of the anti-slip agent include alumina such as White Morundum WA (manufactured by Showa Denko KK), silica sand such as silica sand No. 8 (Sobueclay Shoji Co., Ltd.), nylon powder, vinyl chloride resin beads, and methyl methacrylate polymer beads. It is preferable to use pigments such as, medium-density polyethylene powder, ultra-high-molecular-weight polyethylene powder, kaolin, white carbon, granular pumice, activated alumina, artificial lightweight aggregate, cold water stone, perlite, calcined hillstone, and fluorescent pigment. These can be used alone or as a mixture of two or more. By using these anti-slip agents, the effects of the present invention can be more effectively exerted.

The content of the anti-slip agent is 10 to 100 parts by weight based on 100 parts by weight of the aqueous resin. This can prevent the floor from slipping. If the amount is less than 10 parts by weight, it may not be possible to prevent the floor from slipping. On the other hand, when the amount exceeds 100 parts by weight, the strength of the coating film composed of the water-based paint for floor may decrease.

Preferably, the content of the above anti-slip agent is
12.5 to 100 based on 100 parts by weight of the aqueous resin
Parts by weight. Accordingly, even if a slipping substance such as oil or water exists on the surface to which the water-based paint for floor surface is applied, a sufficient slip-preventing effect can be exhibited. For the same reason, the content is more preferably 25 to 50 parts by weight.

Some commercially available water-based resins have already been mixed with some volatile components such as a solvent in the water-based resin itself, but in this case, the water-based resin (non-volatile The above solvent and the anti-slip agent are added to the component (1) in the above-mentioned weight ratio.

Next, the operation and effect of the present invention will be described.
Since the water-based paint for floors of the present invention has the above-mentioned composition, it can be prevented from adhering foreign matter such as dust by applying it to the floor. Further, it has a gloss and a good appearance, and can maintain excellent gloss and appearance for a long period of time. For this reason, it is not necessary to apply the polishing agent repeatedly to the floor surface.

In addition, even if the user walks on the floor on which the water-based paint for floor is applied to form a coating, the coating does not extend. Therefore, the thickness of the coating film can be kept uniform. Also,
Excellent chemical resistance, such as acidic substances, alkaline substances, high temperature oil and water. Therefore, the floor surface is not damaged even if a detergent having a strong detergency is used. Therefore, it is possible to prevent the floor material from deteriorating and extend the service life.

The water-based paint for floors of the present invention is completely different from the conventional polishes and paints such as waxes, and is different from the conventional water-based paint for floors in that before the water-based paint for floors is applied, the floor is subjected to a washing treatment and an existing coating film. The above-mentioned excellent effects can be exhibited even when the composition is applied directly to the floor surface without performing a base preparation step such as peeling, polishing, and undercoating.

Furthermore, surprisingly, practically sufficient adhesion of the coating film to the surface to be coated with oil-soluble or water-soluble stains such as oil without completely removing them is also achieved. And the above-mentioned useful effects can be obtained at the same time. In addition, even if a sliding substance such as water or oil is present, a coating film having a high sliding effect can be formed by directly applying the water-based floor paint to the surface thereof.

Therefore, the water-based paint for floors according to the present invention not only replaces the application of a polishing agent required for maintenance of the floor material, but also removes the paint film itself, which has been conventionally required. Becomes unnecessary. Therefore, according to the water-based paint for floors of the present invention, maintenance work and cleaning work of the floor are extremely easy.

And, the maintenance of the floor is made easier.
The following effects are obtained. Conventionally, when repairing a floor inside a building, it has been necessary to pay great attention to ventilation since harmful components such as organic solvents contained in the repair material volatilize during or after construction. However, since the water-based paint for floors of the present invention is water-based and has a low organic solvent concentration, it is only necessary to perform simple ventilation such as opening a window and performing ventilation.

Further, in a business office such as a fast food restaurant which is open all year round, the floor repair time is extremely limited, so that the floor repair work must be completed within at least several hours. However, according to the water-based paint for floors of the present invention, a single-layer coating exhibits a sufficient function as a coating film, and it is water-based, Dry with. for that reason,
Walking on the painted surface several hours after painting does not cause any problems such as unevenness of the paint film. Therefore, it is particularly excellent as a material for maintenance of indoor floors.

In particular, various problems relating to the indoor floor, which have been extremely difficult to deal with conventionally, for example, stone materials such as marble, which are frequently used as floor materials for buildings, cannot be managed by an appropriate maintenance management method. The surface material was left untreated and naturally degraded. If stone material such as marble was used as the floor material immediately below the urinal of a toilet, the stone material deteriorated in a very short time due to the acid in the urine that was scattered. That the cooking floor of the restaurant became slippery due to the spilled cooking oil,
The floor paint at the entrance and exit of a department store has been unable to find a suitable solution in the past, such as being wet and slippery in the case of rain, making it difficult to endure complaints. It is a very effective solution.

The reason that the water-based paint for floors of the present invention exhibits the above-mentioned excellent effects is as shown in FIG.
After the application of the floor coating, the floor coating hardens and forms a hard coating film 2. It is also considered that this is because the anti-slip agent 1 protrudes from the surface of the coating film 2 and forms irregularities on the surface of the coating film 2.

Next, as in the second aspect of the present invention, the water-based paint for floor contains methanol and / or a surfactant, and the content of the methanol is 100 parts by weight of the aqueous resin. It is preferable that the content of the surfactant is 0.1 to 10 parts by weight based on 100 parts by weight of the aqueous resin. Thereby, the above-mentioned effect of the water-based paint for floor can be more effectively exhibited. Further, drying of the water-based paint for floors is quickened.

On the other hand, when the content of methanol is less than 2 parts by weight, or when the content of surfactant is less than 0.1 part by weight, the above effects due to the addition thereof can be obtained. May not be. On the other hand, when the content of methanol exceeds 100 parts by weight, the working environment may be deteriorated, and the intention of using the water-based paint may be impaired.
On the other hand, when the content of the surfactant exceeds 10 parts by weight, poor drying and poor adhesion may occur.

As the above-mentioned surfactant, a nonionic surfactant, an anionic surfactant, an amphoteric surfactant, a cationic surfactant and the like can be used. Examples of the nonionic surfactant include nonionic surfactants such as saponins, alkylene oxide derivatives, glycidol derivatives, fatty acid esters of polyhydric alcohols, alkyl esters of sugars, urethanes, and ethers. .

As the above saponin, there is, for example, a saponin formed by binding to a steroid. Examples of the alkylene oxide derivative include polyethylene glycol, polyethylene / polypropylene glycol condensate,
Examples include polyethylene glycol alkyl or alkyl aryl ethers, polyethylene glycol esters, polyethylene glycol sorbitan esters, polyalkylene glycol alkylamines or amides, and polyethylene oxide adducts of silicone. Examples of the glycidol derivative include alkenyl succinic acid polyglyceride and alkylphenol polyglyceride.

Examples of the anionic surfactant include triterpenoid saponins, alkyl carboxylate, alkyl sulfonate, alkyl benzene sulfonate, alkyl naphthalene sulfonate, alkyl sulfates, alkyl phosphates, N phosphates and the like. A carboxy group, a sulfo group, a phospho group, such as -acyl-N-alkyltauric acid, sulfosuccinates, sulfoalkylpolyoxyethylene alkylphenyl ethers, polyoxyethylene alkyl phosphates, and the like.
There is an anionic surfactant containing an acidic group such as a sulfate group or a phosphate group.

Examples of the amphoteric surfactant include amino acids, aminoalkylsulfonic acids, aminoalkylsulfuric acid or phosphoric acid esters, alkylbetaines, amineimides, and amine oxides.

Examples of the cationic surfactant include alkylamine salts, aliphatic or aromatic quaternary ammonium salts, heterocyclic quaternary ammonium salts such as pyridinium and imidazolium, and aliphatic or heterocyclic rings. Including phosphonium or sulfonium salts.

Next, as in the third aspect of the present invention, the average particle size of the anti-slip agent is 1.1 to 3.5 times the average film thickness of the coating film applied to the floor and dried. Is preferred. This makes it possible to form a coating film that more effectively prevents the floor from slipping. Also, the floor surface is glossy and the appearance is good. On the other hand, when the average particle size of the anti-slip agent is less than 1.1 times the thickness of the coating film, the floor surface may be slippery. On the other hand, if it exceeds 3.5 times, the gloss of the floor surface may be weakened and the appearance may be deteriorated.

Next, as in the fourth aspect of the present invention, the floor is made of, for example, any one of a resin material, a ceramic material, a stone material, a wood material, and a concrete material.

Examples of the resin-based material include a composition vinyl floor tile, a homogeneous vinyl floor tile, a composite floor tile, a rubber tile, a vinyl floor sheet having no foam layer, a vinyl floor sheet having a foam layer, a cushion floor, and a linoleum. Floor materials and the like can be used.

As the ceramic material, for example, a ceramic tile, a ceramic tile, a ceramic tile, a ceramic block, a non-slip tile, and the like can be used.
As the stone material, for example, a stone material for construction such as granite, marble, terrazzo tile, natural stone, processed stone, or other stone materials can be used.

As the wood-based material, for example, cork tile, wood brick, painted floor material and the like can be used. As the concrete material, for example, mortar or the like can be used. Further, in addition to the floor surface described above, the floor surface may be an edge deck, a single-layer flooring, or a composite flooring, which is generally applied with floor coating.

Further, in order to improve the weather resistance of the coating film of the water-based paint for floor surface, it is necessary to use a barnock (Dainippon Ink Chemical Industry Co., Ltd.)
Alkyd resins such as Residrol (manufactured by Hoechst Japan K.K.), glass coat (Sanyo Chemical Industries, Ltd.)
Acrylic silicone resin such as Nanocryl (manufactured by Toyo Ink Mfg. Co., Ltd.), Lumiflon (Asahi Glass Co., Ltd.)
) And Zeffle SE (manufactured by Daikin Industries, Ltd.).

The aqueous paint for floors of the present invention contains an antifoaming agent, a leveling agent, and the like, as long as the effects of the present invention are not impaired.
Additives contained in general paints, such as viscosity modifiers, anti-settling agents, anti-segregation agents, wetting agents, antistatic agents, oil repellents, film-forming aids, freeze stabilizers, plasticizers, preservatives, dyes, pigments, etc. Can be blended.

Next, as a floor surface structure formed by applying the above-mentioned water-based paint for floor surface, for example,

BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment An embodiment of the present invention is a water-based paint for floor surface to be applied to a floor surface. The water-based floor coating composition of this embodiment comprises an aqueous resin containing a curing agent, a solvent, an anti-slip agent, methanol, and a surfactant. For 100 parts by weight of aqueous resin,
91 parts by weight of a solvent, 25 parts by weight of an anti-slip agent, 0 to 91 parts by weight of methanol, and 0 to 18 parts by weight of a surfactant were used.

As the aqueous resin, a resin obtained by blending 100 parts by weight of a curing agent with respect to 20 parts by weight of CAT-EPK (manufactured by Toyo Morton Co., Ltd.) was used. As a curing agent, M
F-40 (manufactured by Toyo Morton Co., Ltd.) was used. CAT-
EPK and MF-40 contain 75% by weight and 40% by weight of a nonvolatile component (aqueous resin), respectively. Therefore, CAT-EPK and MF-40 contain 55 parts by weight of the non-volatile component (aqueous resin) in the total weight of 120 parts by weight.

Further, water was used as the solvent. As an anti-slip agent, White Random WA # 600 (manufactured by Showa Denko KK) was used. As a surfactant, BYK-
380 (manufactured by BYK Japan KK) was used. The average particle size of the anti-slip agent is 1.1 times the average thickness of the dried water-based floor coating.

Next, in producing the water-based paint for floor, first, 20 parts by weight of CAT-EPK, 10
0 parts by weight of MF-40, 50 parts by weight of water and 14 parts by weight of an anti-slip agent were mixed. Next, methanol and a surfactant were added to the mixture in an amount of 0 to 91 parts by weight and 0 to 18 parts by weight, respectively, based on 100 parts by weight of the nonvolatile components (aqueous resin) in CAT-EPK and MF-40. Parts and mixed. As a result, the above water-based paint for floor was obtained.

Next, the obtained water-based paint for floor surface was directly applied to the floor surface which had been previously washed with marble floor material without undercoating, and dried to remove the solvent and to remove the water-based resin. Cured. The number of application is one. As a result, a coating film composed of a water-based paint for floor was formed on the floor of the marble floor material. The thickness of the dried coating film was 20 μm.

Next, the adhesion performance of the coating film was evaluated. In the evaluation, the content of methanol and the surfactant in the water-based floor coating was changed, and a scratch test of the coating film was performed for each content. In this test, both the nail scratching method using a nail to scratch the coating surface and the coin scratching method using a coin to scratch the coating surface were performed.

The evaluation criterion of the measurement results is “○” when the coin is not easily peeled by the coin scratch method and the nail scratch method, and “「 ”when the nail is not easily peeled by the nail scratch method but is easily peeled by the coin scratch method. Δ ”, and“ x ”when easily peeled by the coin scratch method and the nail scratch method. Table 1 shows the evaluation results.

According to Table 1, 0 to 91 parts by weight of methanol,
And when the surfactant is 0 to 18 parts by weight,
The coating surface is not damaged for the nail scratch method,
Also, it can be seen that as the content of both increases, damage to the coating film surface can be suppressed.

[0055]

[Table 1]

Embodiment 2 This embodiment differs from Embodiment 1 in that the water-based paint for floor is applied to the surface of marble to which salad oil has been applied. The same water-based paint for the floor surface as in the first embodiment is used. Salad oil is a general commercially available edible oil, which was applied to a marble floor at 5 g / m ² . The thickness of the dried coating film of the water-based floor coating was 20 μm. The adhesion performance of the coating film composed of the water-based floor coating was evaluated in the same manner as in Example 1, and the results are shown in Table 2. Table 2 shows that the greater the content of methanol and surfactant, the more the damage to the coating film surface can be suppressed.

[0057]

[Table 2]

Embodiment 3 In the water-based floor coating composition of this example, 25 parts by weight of an anti-slip agent and 0 parts by weight of methanol were added to 100 parts by weight of an aqueous resin.
143 parts by weight and a surfactant of 0 to 29 parts by weight. Suisei opal (Gengen Chemical Industry Co., Ltd.) was used as the aqueous resin.

The Suisse opal contains a non-volatile component at 37% by weight. Suisei opal does not contain a curing agent. As the anti-slip agent, White Morundum WA # 600 (manufactured by Showa Denko KK) was used. Water was used as the solvent. As a surfactant,
BYK-380 (manufactured by BYK Japan KK) was used. The average particle size of the anti-slip agent is 1.1 times the average thickness of the dried water-based floor coating.

In the production of the water-based paint for floors, first, 100 parts by weight of Suisse opal, 1 part by weight of water, and 14 parts by weight of an anti-slip agent were mixed. Next, methanol and a surfactant are added to the mixture.
Non-volatile components (water-based resin) in Suisei Opal 100
0 to 143 parts by weight, 0 to 29 parts by weight
It was added and mixed so as to be parts by weight. Thus, the water-based paint for floor was obtained.

The above-mentioned water-based paint for floor was applied to a marble floor to which salad oil was applied, and dried to form a coating film composed of the water-based paint for floor. The amount of salad oil applied is
It was 5 g / m ² . The thickness of the dried coating film was 20 μm. The adhesion performance of the coating film composed of the water-based floor coating was evaluated in the same manner as in Example 1, and the results are shown in Table 3.

From Table 3, it was found that the greater the content of methanol and surfactant, the more the damage to the coating film surface could be suppressed. In addition, although the water-based paint for floors of this example has slightly lower adhesion of the coating film as compared with Embodiment 2, if methanol or / and a surfactant is added, practically sufficient adhesion performance can be obtained. I knew it could be done.

On the other hand, for comparison, an aqueous resin composed of Suisse opal was applied to the salad oil application surface. In this case, the amount of methanol is about 2 to 2 in comparison with this example.
Only when 3 times and about 1.5 to 3 times the amount of surfactant was added, good adhesion performance was obtained.

[0064]

[Table 3]

Embodiment 4 In this example, the adhesion performance of a coating film when a water-based coating material for floor surface was applied to various floor materials was evaluated. The water-based floor paint used for the evaluation was an aqueous resin containing a curing agent, a solvent,
It consists of methanol and an anti-slip agent. The aqueous floor coating composition contains 91 parts by weight of a solvent, 18 parts by weight of methanol, and 25 parts by weight of an anti-slip agent with respect to 100 parts by weight of an aqueous resin containing a curing agent.

As the aqueous resin, CAT-EPK (manufactured by Toyo Morton Co., Ltd.) to which MF-40 (manufactured by Toyo Morton Co., Ltd.) was added as a curing agent was used. As the anti-slip agent, White Morundum WA # 600 (manufactured by Showa Denko KK) was used. The average particle size of the anti-slip agent is 1.1 times the average thickness of the dried water-based floor coating.

In producing the water-based paint for floors, 20 parts by weight of CAT-EPK and 100 parts by weight of M
F-40, 50 parts by weight of water, 10 parts by weight of methanol, and 14 parts by weight of an anti-slip agent were mixed.

Next, the above-mentioned water-based paint for floor was applied once on the floor of each of the floor materials of P tile (plastic tile), porcelain tile and marble. The thickness of the dried coating is
It was 20 μm. The floor surface to which the floor-based water-based paint is applied is a washed surface obtained by cleaning the surface of each floor material, a coated surface in which 5 g / m ² of salad oil is applied to the surface of each floor material, and a floor-based water-based paint described above. The surface of the coating film was prepared by washing the surface of the coating film and the surface of the coating film coated with 5 g / m ² of salad oil.

Then, the adhesion performance of the coating film composed of these floor-based water-based paints was evaluated. As a result, there is almost no difference in the adhesion performance between the P tile, the porcelain tile, the marble floor material, and the surface of this coating film, and both the washed surface and the oil-coated surface. The results were satisfactory (corresponding to ○ in the evaluation criteria of adhesion performance in Example 1).

Embodiment 5 In this embodiment, the anti-slip performance of the coating film when the type and content of the anti-slip agent were changed was evaluated. The floor-based water-based paint used for the evaluation includes a water-based resin containing a curing agent, a solvent, methanol, and an anti-slip agent. The water-based paint for the floor is based on 100 parts by weight of the water-based resin containing the curing agent.
It contains 270 parts by weight of solvent, 18 parts by weight of methanol and d parts by weight of an anti-slip agent.

In producing the above-mentioned water-based paint for floor, 20 parts by weight of CAT-EPK (aqueous resin), 10
0 parts by weight of MF-40 (curing agent), 150 parts by weight of water (solvent), 10 parts by weight of methanol, and c parts by weight (this is a water-based resin containing a curing agent in a floor-based water-based paint ( (Equivalent to 100 parts by weight of the nonvolatile component) and various anti-slip agents.

Examples of the anti-slip agent include White Morundum WA # 600, White Morundum WA # 400,
White Morundum WA # 320, White Morundum WA # 280, White Morundum WA # 240, White Morundum WA # 180, and Silica Sand No. 8 were used. As described above, various water-based paints for floors having different types and contents of the anti-slip agent were obtained.

Next, 0 to 60 g / m ^{2 is} applied to the surface of the P tile.
Was applied, and the above-mentioned water-based paint for floor was applied to the applied surface and dried to form a coating film. The thickness of the dried coating film was 20 μm. On the other hand, for comparison, a resin wax for all floors (manufactured by Linley Co., Ltd.) was applied under the same application conditions as the water-based paint for floors to form a coating film.

Next, the anti-slip performance of these coating films was investigated. In this performance evaluation, the test surface was a brass weight 250g.
Was measured by measuring the angle at which the weight began to slide when the test surface was tilted. Silicone rubber was applied to the sliding surface of the weight, assuming a non-slip rubber shoe.

On the other hand, the same test was carried out on a weight that was left on a metal surface without attaching silicone rubber, assuming slippery shoes such as leather shoes. When the test was performed on a metal surface without applying silicone rubber, the slip angle without applying salad oil was 36 ° at the maximum, and when oil was applied, the slip angle was 30 ° or less in any case. There was no big difference. In addition, the measurement variation of this test was about ± 3 degrees regardless of whether silicon rubber was applied or not. From this, based on the test results when silicone rubber was applied, the anti-slip performance of the coating film when the type and amount of the anti-slip agent were changed was compared and evaluated. Table 4 shows the evaluation results.

In Table 4, when the slip angle is 36 degrees or more, the anti-slip effect is the best (）), when the slip angle is 30 to 36 degrees, the anti-slip effect is good (○), and when the slip angle is 20 to 30 degrees. Indicates that the sample has an anti-slip effect (△), and when the angle is less than 20 degrees, the sample has no anti-slip effect (×). When the oil is not applied, the slide-out angle of the weight on the coating film is
Indicated by measured values.

From the above results, it can be seen from the above evaluation results that a coating film having anti-slip performance can be formed with the floor-based water-based paint containing an anti-slip agent. In particular, since the relative value of the average particle size of the anti-slip agent is 1.5 (measured value of 30 μm) with respect to the relative value of the coating film thickness after drying of 1 (measured value of 20 μm), a considerable anti-slip effect is obtained. When the relative value of the average particle size of the anti-slip agent is 2.5 (actual value 50 μm), a sufficient anti-slip effect is obtained, and the relative value of the average particle size of the anti-slip agent is 3 (actual value). 60μm) or more,
It was found that there was an excellent anti-slip effect.

The amount of the anti-slip agent added is 2.5% to 20% by weight (c%) excluding the anti-slip agent from the weight of the water-based paint for the entire floor (in the water-based paint for the floor). (12.5 to 100 parts by weight based on the weight (d part) of the aqueous resin (non-volatile component) containing the hardener)), it was found that a sufficient anti-slip effect was exhibited. On the other hand, wax has an excellent anti-slip effect when oil is not present on the surface, as in the case of the water-based floor paint of this example, but when oil is applied to the surface, the anti-slip effect of wax is obtained. Was significantly inferior to the water-based floor paint of this example. From this,
It can be seen that the anti-slip performance of the water-based paint for floors of this example is superior to wax.

Embodiment 6 In this embodiment, the relationship between the content of the anti-slip agent in the water-based floor paint and the abrasion resistance and drying time of the coating film made of the water-based floor paint was investigated. The water-based paint for floors to be used for the survey was 100 parts by weight of water as a solvent, 9 parts by weight of methanol, and 100 parts by weight of an aqueous resin containing a curing agent.
The anti-slip agent is contained in an amount of 0 to 100 parts by weight.

The aqueous resin is 20 parts by weight of CAT-EPK.
Was added with 100 parts by weight of MF-40 as a curing agent. Anti-slip agent is White Morundum WA # 24
0 was used. Next, the above-mentioned water-based paint for floor is applied to the floor material (P
Tile) and dried. The thickness of the dried coating film was 20 μm.

Next, the abrasion resistance of the coating film made of the above-mentioned water-based paint for floor and the drying time of the water-based paint for floor were investigated. The abrasion resistance of the coating was measured using a taper abrasion tester. AA180 No. specified in JIS R6252 was used as the polishing paper. The total load applied on the test piece was 1 kg including the weight of the rubber disk. The coating film was rubbed with the above taper abrasion tester, and the surface of the floor material was reduced to 50.
The point of time when% exposure was reached was taken as the wear end point (the number of times of friction).

In measuring the drying time of the floor coating, the floor coating was applied at 20 ° C.
Dried under 65% RH. A gauze was put on the coating film every predetermined time, and a cylindrical weight having a flat bottom with a diameter of 40 mm and a mass of 500 g was put on the gauze, and after 12 hours, the weight and the gauze were removed and traces of the gauze were observed. . The time at which no trace of gauze was observed was taken as the drying time.

Table 5 shows the measurement results. From Table 5,
It was found that when the anti-slip agent was added in an amount of 12.5 to 100 parts by weight based on 100 parts by weight of the aqueous resin containing the curing agent, sufficient abrasion resistance was obtained and drying was quick. In particular, it has been found that when 25 to 50 parts by weight of the anti-slip agent is added to 100 parts by weight of the above-mentioned non-volatile component, extremely excellent wear resistance is obtained and the drying time is short.

Embodiment 7 In this embodiment, the glossiness and chemical resistance of a coating film made of a water-based floor coating were evaluated. The water-based paint for floor used in the investigation contains 100 parts by weight of water as a solvent, 9 parts by weight of methanol, and 25 parts by weight of an anti-slip agent with respect to 100 parts by weight of an aqueous resin containing a curing agent.

The anti-slip agent was White Morundum WA #
600 was used. Other than that, the water-based paint for floors was manufactured like Example 6. Next, the above-mentioned water-based paint for floor was applied and dried in the same manner as in Example 6 to obtain a coating film having a dry thickness of 20 μm.

Next, the gloss of the coating film was observed. The observation method used a visual test with the naked eye. In addition, the chemical resistance of the coating film was evaluated. This performance test relates to the acid and alkali resistance of the coating. Regarding acid resistance, the coating film was brought into contact with a 5% acetic acid aqueous solution for 6 hours. Regarding the alkali resistance, the coating film was brought into contact with a 1% aqueous solution of sodium carbonate for 6 hours. As a result, the gloss and chemical resistance of the coating film were the same between the water-based floor coating for maintenance and the wax without any difference, and no abnormality was observed.
