A small carpet may be placed at the entrance to make it easier to change into indoor shoes. Furniture is often placed on rugs to protect the flooring. In this way, a carpet made of woven fabric, natural material, etc., an electric carpet, a center rug, or rather a rug such as a rag, a bat, a fur, and a mat are placed on the floor material having a smooth surface, and the floor is partially laid. It is customary to cover the floor with furniture and furnishings such as tables, chairs, sofas and shelves.

用いられている。However, when a person walks on a rug or leans on furniture such as a sofa, furniture and furniture may be displaced from predetermined positions. Therefore, there has been a case where a non-slip material is conventionally attached to a rug or a lower surface of a sofa. Non-slip materials include polyethylene resin and ethylene-vinyl acetate copolymer (hereinafter "EVA").

欠点がある。Japanese Patent Application Laid-Open No. 11-35747 discloses a non-slip material made of a synthetic resin foam containing polyethylene polymerized using a metallocene catalyst. However, although polyethylene is excellent in workability and mounting properties as compared with EVA, it is inferior in slip resistance. In addition, in terms of durability (set restoring property), a place where furniture and furniture are placed for a long time remains crushed and does not recover to its original thickness, so there is a disadvantage that a step is formed on the non-slip material. .

M "), a foam having a high anti-slip effect can be obtained. Further, since the above-mentioned mixture has excellent resilience and familiarity peculiar to rubber, it is excellent not only in anti-slip effect but also in durability (sag recoverability) as compared with polyethylene. By preparing this foam in the form of a sheet, laying it under a rug or attaching it, or cutting it into strips or molding it into a foam molded product, attaching it to the sofa leg, and using it This has led to the completion of a non-slip material having a sufficient anti-slip effect and having a light weight and a moderate cushioning property.

させることが好ましい。The non-slip material of the present invention can be produced by forming a foam into a sheet and then processing it into a desired shape.
However, it can be formed by foaming into a predetermined desired shape. The resulting non-slip material is about 4 thickness
Although it is often about 12 mm, it can be used as it is,
When thinner is preferable, it can be processed to a required thickness, for example, 1 to 3 mm using a slicer or the like. It is preferable that the thickness of the sheet is changed depending on the place to be applied, the application, and the like.

状の凹凸を設けることができる。Further, in the vicinity of the surface of the sheet-like foam obtained by the above-mentioned method, a resin of a low-foaming layer generally called a skin layer is formed. This low foam layer reduces the anti-slip effect. In order to more reliably obtain the anti-slip performance, it is preferable to remove this skin layer by slitting the low foam layer. In addition, embossed irregularities can be provided on the foam.
