DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the anti-slip synthetic resin sheet 1 of the present invention is formed by bonding an anti-slip layer 4 made of an ethylene-α-olefin copolymer to one or both sides of a cloth-like body 3 made of synthetic resin. .
[0014]
In the present invention, the cloth-like body is a general term for a flexible sheet-like body made of a linear body, and is a monofilament, tape, yarn, split yarn, short fiber spun yarn, etc. Using the bodies 2a and 2b, as shown in FIG. 1 (A), a woven fabric such as plain weave or twill weave is used, and as shown in FIG. 1 (B), a large number of filaments 2a are arranged in one direction. A cross-bonded cloth (SOF) in which a large number of linear bodies 2b are arranged side by side in an orthogonal direction thereon and the intersections thereof are joined using an adhesive such as a hot melt agent or by heat fusion. Can be used. Further, as shown in FIG. 1C, it is also possible to use as a nonwoven fabric in which synthetic resin short fibers are laminated or a braided fabric (not shown).
[0015]
The filament 2 may be a single layer of a crystalline resin, but can be a laminate in which a bonding layer is formed on at least one side of a synthetic resin layer serving as a base layer.
[0016]
The synthetic resin constituting the monolayer of the filament 2 or the base layer of the laminate is preferably a resin having a large stretching effect, generally a crystalline resin, such as high density polyethylene, polypropylene, ethylene / propylene copolymer, etc. Polyester such as polyolefin, polyethylene terephthalate, polybutylene terephthalate, polyamide such as nylon 6, nylon 66, or the like can be used.
[0017]
Of these, polyolefins such as polyethylene and polypropylene are desirable from the viewpoint of processability and economy, and linear low density polyethylene polymerized using a metallocene catalyst is particularly preferred. By using a linear low density polyethylene polymerized using a metallocene catalyst, a tough sheet having excellent flexibility can be obtained. The metallocene catalyst will be described later.
[0018]
The joining layer joins the filaments 2 after the filaments 2 are made into a cloth shape, or joins between the cloths 3 and the anti-slip layer 4, from the synthetic resin constituting the base layer 6. A synthetic resin having a low melting point and excellent heat-fusibility is used.
[0019]
Specifically, polyolefins such as polyethylene, polypropylene and ethylene / propylene copolymer, polyesters such as polyethylene terephthalate and polybutylene terephthalate, nylon 6 and polyamides of nylon 66 can be used, and the relationship with the base layer synthetic resin Thus, a synthetic resin having a melting point lower than that of the base layer is selected.
[0020]
The wire 2 may be a single layer as shown in FIG. 3 (A), and the bonding layer 7 is laminated on one side of the base layer 6 as shown in FIG. 3 (B). Alternatively, as shown in FIG. 3C, the base layer 6 may be laminated on both sides. Further, a seascore structure as shown in FIG. 3D and a side-by-side method as shown in FIG. Among them, as shown in FIG. 3C, it is desirable to laminate a low melting point bonding layer 7 on both surfaces of the tape-like base layer 6.
[0021]
Moreover, it is preferable that the linear body 2 uses the synthetic resin containing the unit derived from a polar monomer. As a synthetic resin containing a unit derived from a polar monomer, a homopolymer of a polar monomer or a copolymer of a polar monomer and another monomer can be used. Or mixed with other synthetic resins.
[0022]
Furthermore, it is also desirable to introduce a unit derived from a polar monomer by blending a modified polyolefin obtained by modifying a polyolefin with a polar monomer alone or in a base polyolefin.
[0023]
Examples of polar monomers constituting the copolymer or modifying the polyolefin include unsaturated carboxylic acids such as (meth) acrylic acid, (meth) acrylic acid ester, maleic acid and its anhydride, fumaric acid, itaconic acid, etc. The amount of the polar monomer to be modified is preferably 0.01 parts by weight to 20 parts by weight and more preferably 0 parts by weight with respect to 100 parts by weight of the polyolefin. 1 to 10 parts by weight. If it is 0.01 parts by weight or less, the effect of improving the adhesive strength is small, and if it is 30 parts by weight or more, the irritating odor may become strong.
[0024]
The reaction between these polar monomers and polyolefin can be carried out by kneading at a high temperature in the presence of a radical generator such as peroxide, or by dissolving in a solvent and heating to react.
[0025]
The amount of the modified polyolefin added to the polyolefin is preferably 0.5 to 20 parts by weight, more preferably 1.0 to 15 parts by weight with respect to 100 parts by weight of the polyolefin.

From the standpoint of the properties and light transmittance, a method of obtaining a laminated body of the base layer 6 and the bonding layer 7 in a single step by a multilayer coextrusion method is desirable. The seascore structure or side-by-side structure is generally based on a coextrusion method.
[0030]
Further, as a means for stretching to form the filament 2, a film that becomes the base layer 6 may be stretched in a uniaxial direction and then laminated with a synthetic resin that becomes the bonding layer 7 and may be slit into a tape shape, or It can also be obtained by stretching in a uniaxial direction before or after slitting the laminated film in which the base layer 6 and the bonding layer 7 are laminated. The draw ratio is usually about 3 to 10 times.

Moreover, as the filament 2, a stretched monofilament can be used, and further, a short fiber can be used when a non-woven fabric is used. Moreover, the twisted yarn obtained by spinning a short fiber can also be used.
[0033]
The obtained striated body 2 such as a uniaxially stretched tape is woven into plain weave, twill, etc., or a large number of striated bodies 2a are arranged in parallel, and the striated bodies 2b are arranged so as to cross over them. The cloth-like body 3 made into a cross-bonded cloth can be used. Moreover, it can be knitted by knitting into the cloth-like body 3, and can also be used as a non-woven fabric using short fibers. The cloth-like body 3 joins the intersections of the filaments 2 as necessary. As a method of joining the intersections of the filaments 2, bonding can be performed with a hot-melt adhesive, and when the filaments 2 have the bonding layer 7, bonding is performed by thermocompression using a hot roll. can do.
