May be printed on the surface of the sheet as a guide for cutting, or perforations or cuts may be made along the cells to make it easier to separate the sheet itself for use.

Next, the production method of the present invention will be described. In the first step, 260 g of a vinyl chloride foam paint layer (2) is coated on a base layer (1) of a polyester film having a thickness of about 25 to 180 microns. / M ² , dried, and temporarily wound around a roll in an unfoamed state.

In the second step, a vinyl chloride paint layer (3) is formed on the unfoamed vinyl chloride foam paint layer (2).
By heating and foaming these layers at 180 ° C. to 200 ° C. at the same time or immediately after the application of 120 g / m ^2, the surface of the vinyl chloride paint layer (3) is affected by the unevenness of the foaming on the lower surface. Receiving them, a fine uneven surface of a crimped pattern is formed and integrated.

Further, when a slip-resistant sheet having an adhesive layer (4) and a release layer (5) is formed, an adhesive layer (4) may be formed on the back surface of the base layer (1) of the polyester film.
g / m ^2, and a third step of forming a release layer (5) thereunder is further added.

The above described slip-prevention sheet is made of a foamed paint layer of vinyl chloride (2) and a paint layer of vinyl chloride (3).
And the amounts of the adhesive (4) and the release layer (5) to be applied are shown below. Example of paint composition Vinyl chloride foam paint layer Vinyl chloride resin 39% Plasticizer 23% Inorganic filler 25% White pigment 3% Foaming agent 8% Stabilizer 1% Color pigment, fungicide 1% Total 100% Amount 260 g / m ² Vinyl chloride paint layer Vinyl chloride resin 40% Plasticizer 48% Inorganic filler 8% Stabilizer 1% Color pigment, fungicide 3% Total 100% Coating amount 120g / m ² Adhesive Layer Coating amount 30 g / m ² Release layer Coating amount 50 g / m ²

[0013] Incidentally, PVC paint layer (3) the coating amount of the vinyl chloride coating of 100g / m ² ~150g / m ² is preferred in the coating amount of the thin PVC paint 150 g /
If it is more than m ² , fine uneven pattern of the vinyl chloride paint layer (3) cannot be formed, but even if it is less than 100 g / m ^{2, the} fine unevenness is as long as a thin paint layer without unevenness can be secured. Is allowed because the grain pattern is formed. Further, even when the coating amount of the vinyl chloride paint of the paint layer (3) of the vinyl chloride is 150 g / m ² or more,
It is also possible to form fine embossed patterns by embossing in a later step.

[0014]

According to the present invention, an unfoamed vinyl chloride foam paint layer is laminated on the surface side of the base layer of a polyester film having strength and heat resistance, and a fine uneven surface can be formed on the foam paint layer. By laminating the paint layer and heating and foaming at the same time as or immediately after laminating the paint layer of vinyl chloride, the thin paint layer of vinyl chloride is on the lower surface along the uneven surface due to the foaming of the foam paint layer of vinyl chloride. Due to the effect of the foam layer, a fine uneven grain pattern is formed on the surface of the vinyl chloride paint layer. A non-slip sheet exhibiting an excellent non-slip function can be used, and the non-slip sheet is laid on a floor with the non-slip surface down.

The reason why the heat-foaming is carried out simultaneously with or immediately after the lamination of the vinyl chloride paint layer on the unfoamed vinyl chloride foam paint layer is that the vinyl chloride paint layer is heated and foamed and then the vinyl chloride paint layer is heated and foamed. This is because, when the layers are laminated, the foamed surface of the finely uneven vinyl chloride is filled with the vinyl chloride paint layer, and the finely uneven grain pattern is not formed in the vinyl chloride paint layer.

That is, in the case of the present invention, a foaming paint layer of vinyl chloride is applied to the base layer of the polyester film, and foaming is carried out at 180 ° C. to 200 ° C. simultaneously or immediately after the paint layer of vinyl chloride is applied. The fine uneven grain pattern due to the influence of the thin PVC paint layer is formed along the shape of the unevenness after foaming, and this fine uneven grain pattern softens the adhesion due to the soft viscous property of the vinyl chloride paint layer. As a result, an anti-slip effect can be formed and maintained.

Originally, when the vinyl chloride paint layer is coated as a single substance, a very adhesive sheet is formed by a combination of the mixing ratios of the plasticizers. In the case of, it has the property that it can be bonded without an adhesive, but the formation of fine uneven patterns like the present invention eases the adhesion of the vinyl chloride paint layer, The surface becomes smooth and dust is less likely to adhere, as a result, even if these sheets are stacked, it becomes difficult for the sheets to adhere to each other,
For this reason, the sheet is easily wound around a roll, and the subsequent printing and punching of the sheet is facilitated.

Further, if the vinyl chloride foam paint layer of the present invention is made thicker, the vinyl chloride paint layer is made thinner, and the foam is heated and foamed simultaneously with lamination, a slip-preventing sheet having cushioning and cushioning effects can be provided.

The slip sheet according to the present invention is such that the mat, the carpet, and the tatami move when used under a door mat, a bathroom mat, a kitchen mat, a carpet, and a floor under a tatami mat. Is prevented, dust is hardly attached, and it can be used cleanly forever.

Furthermore, if the anti-slip sheet of the present invention is adhered to legs of a dining table, a sofa, a TV stand, furniture, etc., rattling of the legs of the furniture or slipping of the legs can be stopped.

In addition, when the cushioning and cushioning properties of the present invention are not normally required, the sheet can be made thin without losing the anti-slip effect. The sheet can be cut to an appropriate size and can be widely used as a personal computer, a word processor mouse pad, or a desk mat as it is or by attaching a backing material to the back surface of the sheet.

Furthermore, if the back surfaces of the anti-slip sheet of the present invention are adhered to each other to form anti-slip surfaces on both sides of the sheet, a slip-preventive sheet that can be easily removed without the need for sticking can be produced. It is possible.
