Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mat with legs used as a cushioning material for baths, closets, etc.

[Conventional technology]

Conventionally, mats made of polyolefin resin foams have been widely used, for example, as bath mats and cushioning materials for closets, taking advantage of the excellent elasticity and moisture resistance of polyolefin resin foams. Mats with legs are used in these mats in order to promote water drainage and improve hygiene in bath mats and ease of handling in closet mats.

However, when these legs are provided on the pine and the pine is rolled up (rolled) into a cylindrical shape to make it easier to carry, the pine may break or crack at the joints of the legs. There is a problem,
This has been a major cause of trouble especially when consumers take the matte products home after purchasing them.

[Problem that the invention attempts to solve]

The object of the present invention is to eliminate the cracking of the legged mat when it is rolled up, improve the performance of the mat product, and eliminate the above-mentioned troubles.

[Means for solving problems]

The purpose of the present invention is to provide a mat with legs provided on a polyolefin resin foam sheet.
The polyolefin resin foam sheet is formed from an ethylene-vinyl acetate copolymer containing 1 to 20% by weight of vinyl acetate, or the entire surface of the sheet is formed between the polyolefin resin foam sheet and the legs. This can be achieved by using a footed mat with excellent cracking resistance provided with a foam made of an ethylene-vinyl acetate copolymer containing 1 to 20% by weight of vinyl acetate.

Hereinafter, the present invention will be specifically explained based on the drawings.

FIG. 1 shows one embodiment of the legged pine according to the present invention, in which 1 is a polyolefin resin foam sheet (hereinafter referred to as foam sheet), 2 is an ethylene resin copolymer component containing vinyl acetate; A foam made of vinyl acetate copolymer (hereinafter referred to as anti-cracking foam), 3 indicates a leg.

In the figure, the foam sheet 1 is not particularly limited, and may be a foam made of various known polyolefin resins, such as polyethylene or polypropylene, and the legs 3 are also not particularly limited. Materials such as polyolefin resin foam sheets or molded plates of various resins can be used.

The feature of the present invention is that the foam sheet 1 and the legs 3 are integrally joined by interposing a crack-preventing foam 2 copolymerized with a specific amount of vinyl acetate. By providing the crack-preventing foam, cracks in the legs of the mat can be effectively prevented.

Here, the crack-preventing foam 2 needs to contain vinyl acetate as a copolymer component in the range of 1 to 20% by weight, and if this amount is less than 1%, it will prevent the mat from cracking. On the other hand, if it exceeds 20%, it is undesirable because it becomes difficult to set manufacturing conditions, excessively increases flexibility, and increases the price.

The thickness and expansion ratio of this crack-preventing foam are determined by the type of foam sheet (polymer type, expansion ratio,
(Thickness, etc.) and the material of the legs, etc., but usually the foaming ratio is 15 to 20 times and the thickness is 2 to 2.
It is best to select and use within the 30mm range.

Furthermore, in the present invention, a mat having a structure as shown in FIG. 2 may be used.

That is, in FIG. 2, the foamed sheet 1 itself, which serves as the footrest surface in the embodiment of FIG. No cracking occurs.

[Effect of idea]

According to the present invention, for example, 20 times, 4 mm and
30x, 30x made of ethylene-vinyl acetate copolymer containing 5% vinyl acetate component on a foam sheet laminated with 5mm polyethylene foam, 30x on the mat body, laminated with 3mm crack-preventing foam. 8mm
Made of polyethylene foam with 65mm wide legs spaced apart
A curvature radius of 70 mm for multiple 18 mm parallel pine mats.
When rolled up, the commercially available pine cracked at the joints of the legs, but the pine of the present invention did not cause any cracking, and even when the radius of curvature was set to 30 mm, no cracking occurred.
