Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-slip flooring material, and more particularly, to an anti-slip flooring material laid on a floor surface of a hospital, a school, a nursing home, stairs, or a vehicle floor such as a train.

[0002]

[Prior art]

 Traditionally, synthetic resin tiles mainly made of vinyl chloride resin and long floor materials have been widely used as floor coverings for office buildings, hospitals, schools, nursing homes, and trains. Such vinyl chloride-based synthetic resin floor materials are usually relatively slippery in corridors, etc., but are not suitable for hospitals, nursing homes, vehicles such as train floors, or stairs or slopes. When it is laid in a place where slip resistance is required, such as a passage, etc., various methods are used to add slip resistance to the floor surface to make it more slippery. As one of them, a synthetic resin floor material with a deep unevenness pattern formed on the surface to impart anti-slip properties, or fine particles of high hardness such as sand or stone are embedded in the surface layer of the floor material to improve anti-slip properties. What is given is known. It is also known that floor mats such as rubber mats do not easily slip.

[0003]

[Problems that the device is trying to solve]

 The above-mentioned conventional synthetic resin flooring material with a deep rugged pattern formed on the surface may not have sufficient slip resistance if the ruggedness is shallow, and if the ruggedness is deep, it may have slip resistance depending on its shape. However, if the unevenness is deep, dust and dirt tend to collect in the valleys of the unevenness, which is difficult to remove, and the unevenness becomes shallow due to clogging of dust and dirt, resulting in sufficient anti-slip properties. There was a problem that I could not do it. On the other hand, synthetic resin floor materials with hard particles such as sand or stone embedded in the surface layer or those dispersed and projected on the surface have excellent anti-slip properties. There was a risk that if you fell on the floor you might suffer abrasion.

Further, rubber floor mats and the like are also excellent in anti-slip properties, but since they do not slip, they have the drawbacks that the soles of shoes are dirty or heel marks are easily attached, and the stain resistance is poor. The only way to make the stains inconspicuous was to use a dark-colored floor mat mainly composed of black. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a flooring material which is excellent in anti-slip properties, stain resistance and design.

[0005]

[Means for solving the problem]

 The above object is achieved by the present invention described below. That is, according to the present invention, a region made of a polymer having a floor slip resistance coefficient of less than 1.0 and a region made of a polymer having a floor slip resistance coefficient of 1.0 or more are dispersed in a plurality to form a floor material surface. It is a non-slip floor material that is characterized by being

[Preferred Embodiment]

 Next, the present invention will be described in more detail with reference to preferred embodiments. The anti-slip flooring of the present invention basically comprises a backing sheet 1 and a surface layer 2 formed thereon as shown in FIG. 1a. The surface layer 2 has a plurality of regions composed of at least one polymer having a floor slip resistance coefficient of less than 1.0 and at least one polymer having a floor slip resistance coefficient of 1.0 or more dispersed therein. It is exposed on the surface. The shapes of the regions made of polymers having different floor slip resistance coefficients are such that they are unevenly formed on the surface, or various patterns such as stripe patterns and screens (screens) are formed of polymers. May be. For example, if the surface is patchy, one of the polymers is a granular discontinuous layer and the other polymer component forms a continuous layer, or all the polymers are granular chips or flakes. The particles may be in close contact with each other to form a surface layer.

When the polymer region is not patchy, for example, a liquid polymer or a sheet polymer is dispersed to form a marble or wood pattern, or a stripe or a lattice. It may be. Also, a liquid polymer having a floor slip resistance coefficient different from that of the polymer (1.0 or more if the floor slip resistance coefficient of the base is less than 1.0) is printed on the surface layer made of the base polymer (silk screen). Alternatively, the floor material surface may be formed into an arbitrary pattern. When the polymer forming the pattern has large irregularities, the surface may be finished to be substantially smooth by pressing with a roll or the like.

In any of the configurations, the surface of the floor material has a region made of a polymer having a floor slip resistance coefficient of less than 1.0 and a region made of a polymer having a floor slip resistance coefficient of 1.0 or more. , Each of which is dispersed in a plurality to form a floor material surface. The backing sheet 1 is usually laminated on the back surface of the surface layer 2 to form a laminated floor material. The polymer used for the backing sheet 1 is not particularly limited as long as it can be laminated with the polymer forming the surface layer 2. When the surface layer is formed only by the polymer component having a floor slip resistance coefficient of less than 1.0, sufficient slip resistance cannot be obtained, and the surface layer is formed by only the polymer component of 1.0 or more. When it is formed, it is not preferable, though it has slip resistance, but stains on the shoe sole and heel marks are liable to be formed, which spoils the aesthetic appearance of the resulting flooring material.

The floor slip resistance coefficient referred to in the present invention is a value measured in accordance with the floor slip test method of "JIS A 1407", and the measurement method falls from the height of a certain angle to the test surface. It takes the form of a pendulum, and the foot model has a metal plate attached to a metal base that imitates the heel, and a stainless steel plate is attached to this. While the pendulum was dropped and the foot was in contact with the surface of the specimen, the heel was attached with a spring so that the same pressure acts on the surface of the specimen, and the sliding piece moved on the surface of the specimen. Read the scale (which has been converted into energy) of the distance and the position where the hammer swings up, and obtain the floor slip resistance coefficient. In the present invention, the floor slip resistance coefficient was obtained from the measured values of a sheet with a substantially smooth surface.

The calculation formula is as follows. EU = ────P ・ D U: Floor slip resistance coefficient P: Spring force (kg) = 3 kg D: Contact distance of sliding piece (cm) E: Scale of hammer swinging position (kg / cm) As for the test method, if a deep uneven pattern etc. is formed on the surface of the test piece, the measured value may appear smaller or larger than that of the test piece with a smooth surface. The coefficient is shown as a value obtained by measuring a molded body portion in which the surface of the test piece is formed into a sheet or film shape and the surface thereof is substantially smooth.

The floor slip resistance coefficient measured by the above test using a test body having a substantially smooth surface is less than 1.0, and preferably 0.4 to 0.9 is a vinyl chloride resin, Vinyl chloride resin in which other polymers are mixed or copolymerized with vinyl chloride resin, and other than vinyl chloride resin, polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin, ethylene-ethyl acrylate copolymer resin, etc. Examples include olefin resin, polyester, polycarbonate and the like.

Examples of the polymer having a floor slip resistance coefficient of 1.0 or more include ultra-low density polyethylene, olefin resin such as ethylene-vinyl acetate copolymer resin, ethylene-acrylic ester copolymer resin, chlorinated polyethylene and the like. In addition to synthetic resins, natural polymers such as cellulose, thermoplastic elastomers such as olefin, urethane and vinyl chloride, or ethylene-propylene rubber, acrylonitrile-butadiene rubber, acrylic rubber, chloroprene rubber, styrene-butadiene rubber It may be a blend of synthetic rubber such as and natural rubber. Among them, those having a floor slip resistance coefficient of 1.5 or more are preferable, and chlorinated ethylene copolymer crosslinked alloys and acrylonitrile-butadiene rubber are particularly preferable.

The surface layer of the flooring material of the present invention includes, for example, a polymer sea component having a floor slip resistance coefficient of less than 1.0 (continuous layer) and a polymer island component having a floor slip resistance coefficient of 1.0 or more (unsaturated layer). Continuous particles) or a mixture of polymer particles (chips or flakes) with a floor slip resistance coefficient of less than 1.0 and polymer particles of 1.0 or more (chips or flakes). It is an inlaid type that is pressed and solidified, and at least a part of both polymers having a floor slip resistance coefficient of less than 1.0 and 1.0 or more are exposed on the surface. These polymer particles may be formed by blending a polymer having a floor slip resistance coefficient of less than 1.0 and a polymer having a floor slip resistance coefficient of 1.0 or more. Also in this case, the particles formed by blending are divided into those having a floor slip resistance coefficient of less than 1.0 and those having a floor slip resistance coefficient of 1.0 or more, and the surface layer is formed in the same manner as above.

When the surface layer is formed using a granular polymer, the particle size is preferably 0.5 to 50 mm in terms of the major axis of the exposed portion on the surface. In the case of a flooring material formed only of particles having a major axis of less than 0.5 mm, stains are likely to stand out, which is not preferable in terms of appearance, and when molded with only particles having a major axis of more than 50 mm, the particles are too large. The anti-slip property is localized, and it becomes difficult to impart substantially uniform anti-slip property as a whole. When particles less than 0.5 mm or more than 50 mm are added, it is preferable to mainly use particles of 0.5 to 50 mm. Even when the granular polymer is not used, the dispersed state of the area where the floor slip resistance coefficient is less than 1.0 and the area where the floor slip resistance coefficient is 1.0 or more, or the size of the area and the pattern may be too large or too small. . For example, if the polymer region has a stripe shape, one stripe may have a width of 0.5 to 50 mm, and if the polymer region has a marble pattern or a pattern formed by printing, it may have a length and width of 50 mm. It is preferable that at least one type of fishing season for both polymers having a floor slip resistance coefficient of less than 1.0 and a polymer having a floor slip resistance coefficient of 1.0 or more is present in an interval of -100 mm.

When the surface layer is composed of a sea component and an island component, for example, as shown in FIG. 2, a vinyl chloride resin paste having a floor slip resistance coefficient of less than 1.0 is used as the sea component, and An acrylonitrile-butanediene rubber (NBR) chip with a slip resistance coefficient of 1.0 or more is used as an island component, and a vinyl chloride resin paste is directly applied to the mold release material or the backing sheet, and the NBR chip is placed on top of it. The vinyl chloride resin paste is gelled by further placing and heating, and the surface is pressed with a roll or the like to form a sheet that becomes a surface layer. The polymer forming the floor surface of the present invention has a floor slip resistance coefficient of less than 1.0. The surface layer is not necessarily composed of two or more types of 0 or more, and may be a surface layer in which regions of a plurality of polymers of three or more types are exposed and dispersed on the surface, and at least one type has a floor slip resistance coefficient of 1.0 or more. It suffices that the floor material surface is formed by the exposed area of the polymer of less than 1.0 and the exposed area of the polymer of 1.0 or more.

In the present invention, the exposed surface area ratio of each surface of the floor material made of a polymer having a floor slip resistance coefficient of less than 1.0 and 1.0 or more is not particularly limited. 1. An exposed surface of a polymer with a coefficient of slip resistance of less than 1.0. The exposed surface of the polymer of 0 or more is 10:90 to 90:10, and more preferably 20:80 to 80:20. If the polymer region with a floor slip resistance coefficient of 1.0 or more is not exposed on the surface at a rate of 10% or more, sufficient anti-slip properties cannot be obtained, and if it is exposed at a rate of more than 90%, shoes It is not preferable because dirt due to friction on the bottom, that is, a heel mark is likely to be attached. The slip-resistant flooring material of the present invention has a surface layer formed of these polymers, and a flooring sheet is formed by laminating a backing sheet on the back surface of the surface layer as needed.

Examples of the polymer forming the back surface layer include vinyl chloride resins, ethylene-vinyl acetate copolymer resins, ethylene-acryl ethyl acetate copolymer resins, olefin resins such as polyethylene and polypropylene, polyester resins, Synthetic resin such as urethane resin, or thermoplastic elastomer such as olefin, ethylene propylene rubber, acrylonitrile-butanediene rubber, acrylic rubber, chloroprene rubber, styrene-butanediene rubber, etc. It may be a plurality of laminates or a foam. The structure and material of the backing sheet are not particularly limited.

The thickness of the anti-slip flooring material of the present invention is not particularly limited, but is preferably about 0.2 to 5 mm, particularly 1.0 to 3.0 mm. Therefore, the thickness of the surface layer or the surface layer and the backing sheet layer is also preferably within this range. The flooring material of the present invention has sufficient anti-slip properties without providing a deep uneven pattern on the surface, but it is also possible to provide an uneven pattern on the surface in order to further improve the anti-slip property or improve the design. .

As described above, in the present invention, the polymer component having a floor slip resistance coefficient of less than 1.0 is excellent in antifouling property, and this is used as a partial region of the surface layer, and on the other hand, it is 1.0 or more. The coexistence of the polymer region having the anti-slip property makes it possible to form a flooring material having a surface layer whose surface is resistant to stains and is hard to slip. Therefore, there is no problem even if the surface layer is colored in a bright color in which dirt is easily noticeable, and it is possible to obtain a floor material that is freely colored and has excellent designability.
