Description

  The present invention relates to an anti-slip synthetic resin sheet, and more particularly to an anti-slip synthetic resin sheet suitable for holding exhibits, preventing load collapse, and the like.

  In recent years, an anti-slip sheet has been widely placed under the exhibits in order to prevent the exhibits from being laterally displaced due to shaking such as an earthquake. In addition, the demand for anti-slip sheets is increasing in a wide range of fields, such as prevention of collapse of goods when carrying luggage and prevention of displacement of installed objects.

  Conventionally, a rubber sheet is often used as such an anti-slip sheet. However, a rubber sheet is not foldable, and a sheet having a particularly large area is used because it is bulky when transported or carried. There is a problem that the property is poor, and there is a problem in durability because the deterioration is large in a state where a load is applied.

  On the other hand, a thermoplastic resin is inexpensive and has excellent mechanical strength, and can be folded with a small area even in a large area. For example, an anti-slip leisure sheet in which a protective layer made of a polyolefin sheet is formed on a flat yarn woven fabric and an anti-slip layer such as an ethylene-ethyl acrylate copolymer is formed thereon has been proposed (Patent Document 1). However, the above-mentioned leisure sheet is an invention that places importance on designability, and is an invention that places emphasis on the transparency of printed printing. As long as it is evaluated, it is not satisfactory.

Under these circumstances, development of an anti-slip sheet that is high in productivity, inexpensive, high in anti-slip property, and easy to collect and recycle is demanded.
Japanese Patent No. 3079054

  The present invention provides an anti-slip sheet that is excellent in anti-slip property and excellent in productivity and mechanical strength.

  The present invention has been made as a result of intensive studies in order to solve the above-mentioned problems. Specifically, a large number of adhesives are locally applied on both sides of a thermoplastic resin substrate with a space therebetween. An anti-slip synthetic resin sheet is provided which is formed by dispersing and forming the adhesive region.

  The present invention also relates to the above-mentioned anti-slip synthetic resin sheet, wherein the thermoplastic resin base material is a uniaxially or biaxially stretched thermoplastic resin sheet, and the thermoplastic resin linear body in which the thermoplastic resin base material is uniaxially stretched. The above-described anti-slip synthetic resin sheet comprising a cloth-like body woven, a cloth-like body woven from a uniaxially stretched thermoplastic resin filament, and one side of the cloth-like body or The above-mentioned anti-slip synthetic resin sheet composed of a laminated sheet with a thermoplastic resin film laminated on both sides, and a laminate in which a cloth-like body is laminated with a bonding layer made of a thermoplastic resin having a low melting point on one side or both sides of a base layer It is intended to provide the above-mentioned anti-slip synthetic resin sheet obtained by intersecting thermoplastic resin filaments and fusing the intersections.

  Furthermore, the present invention provides the above-mentioned anti-slip synthetic resin sheet, wherein the adhesive area is formed by applying an adhesive to dispersed islands, and the adhesive area is formed in a linear shape with the adhesive areas spaced apart in parallel. The above-mentioned anti-slip synthetic resin sheet formed by coating, the above-mentioned anti-slip synthetic resin sheet whose thermoplastic resin substrate is made of polyolefin, and the thermoplastic resin substrate were obtained using a metallocene catalyst An anti-slip synthetic resin sheet made of linear low-density polyethylene is provided.

  The anti-slip synthetic resin sheet of the present invention has a high anti-slip property because an adhesive is applied to both sides, and because the adhesive area is dispersed and formed at intervals, it is easy to peel off, unloads, and collects the sheet. In addition, it is possible to obtain an anti-slip synthetic resin sheet that can be easily performed without causing any trouble. Also, collection and regeneration are easy.
