Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-like body such as a footwear sole and a bathroom mat that does not slip even when worn.

Conventionally, sponge sheets made of ethylene vinyl acetate resin have been used as elastic plate-like bodies such as footwear soles and bath mats, but smooth There was a problem with the floor being slippery when it leaked. Furthermore, when forming a sponge sheet using ethylene vinyl acetate resin, the ethylene vinyl acetate resin and a filler such as calcium carbonate are easily mixed together, resulting in not only poor workability but also poor mixing! After rolling it up into a sheet on a KO-ru, when winding it up on a KO-ru, the so-called 1 loincloth phenomenon occurs.
There was a problem in that a phenomenon called sag occurred and it was difficult to wind up.

The present invention was invented in view of the above points, and its objectives are based on the following four points: The upper layer is not too soft, has shape retention, and does not sink too much when the foot is placed on it. In addition, since both the upper and lower layers are mainly made of ethylene vinyl acetate resin, it is easy to mix with the filler, and there is no sagging phenomenon called the so-called 1-loin phenomenon when winding onto a roll during manufacturing, making it easy to work. Our goal is to provide excellent footwear soles and plate-like bodies such as Ouro washing room mats.

The footwear soles and plate-like bodies such as bathroom mats of the present invention are
Then, 1 part by weight of ethylene acetate resin, 2 to 61 parts by weight of ethylene acetate resin, filler, foaming agent, etc. were mixed to form an upper layer consisting of a sponge sheet. Nyl acetate resin) ethylene resin
Rare acetate branch j IBM? A lower layer made of a sponge sheet is formed by mixing an equal amount of a polypropylene resin with a filler, a filler, and a foaming material 11, and the upper layer and lower layer are laminated together. This will be explained in detail below.

：4j ttt part, filler, foaming agent, etc. are mixed and kneaded in a mill, thirty-sixth mill, etc., then a sponge sheet is formed with a roll, and this is rolled up into a flat plate shape. The upper layer (1) is obtained by cutting or ladling.

In addition, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, ethylene vinyl acetate, etc. After kneading with etc., a non-stick sheet 1- is formed using a 0-roller, and the lower layer (2) is obtained by cutting or punching into the shape of a plate-like object.

An example of the composition of the upper F%f++ and the lower layer (2) is shown below.

Agent: 3 parts stearic acid, 1 part stearic acid
1st part □Next image When the above-mentioned upper F) f+) and lower layer (2) are laminated and heated and pressurized, the ethylene vinyl acetate resin mixed with the upper PK and the ethylene vinyl acetate resin mixed with the lower layer m& are formed. and upper layer (1)
The Horip 0jishi-J resin mixed with K and the polypropylene resin mixed into the lower layer (2) form the upper layer +11 and the lower layer (2).
The foaming agent is completely melted and integrated at the contact area, and the foaming agent is foamed to produce a plate-shaped body such as a footwear sole or a bathroom mat having appropriate cushioning properties.

Here, the reason why Horip D-Hishin resin was mixed in the lower layer (2) in an approximately equal amount to Nibu Shinji Nirudate resin was that the Popu D Hishin resin was mixed in an approximately equal amount to the ethylene vinyl acetate resin. By mixing the lower layer (2) with the upper layer (1)
It is softer than K and has an anti-slip effect. On the other hand, cut into the upper layer + 1) K ethylene dinylacetate resin 100 and add 2 to 10 polypropylene resin.
By mixing the heavy cutting part, it becomes easy to mix the ethylene vinyl acetate resin with fillers such as calcium carbonate, and it also gives an appropriate amount of flexibility, which prevents the so-called 1-loin phenomenon when winding into a zero roll. It eliminates the so-called sagging phenomenon, and is also given appropriate flexibility, yet maintains shape retention and prevents the sole of the foot from sinking in. In this case.

In layer (t) ethylenedipinyl acetate resin 10
The L upper layer (1), which is made of 10 parts by weight or more of polypropylene resin to 0 parts by weight, becomes too soft and the sole of the foot sinks in when the foot is placed on it, and it is difficult to maintain its shape and serves as a binding board. Also, if the polypropylene resin is 2 parts by weight or less, the mixture of ethylene vinyl acetate resin and filler such as calcium carbonate can be used to prevent When winding up the cloth, a sagging phenomenon called the so-called one-loincloth phenomenon occurs, resulting in poor workability.

In the present invention, as described above, both the upper layer and the lower layer contain ethylene vinyl acetate resin and polyurethane resin, and the upper layer and the lower layer are heated and pressurized to form a single layer. , the ethylene vinyl acetate resin and the poly"jO hylene resin, which are present in the upper and lower layers, are both integrated into a binder, and there is no need for a separate special binder. Moreover, the lower layer is made of 7-vinyl acetate resin. It is made by foaming a mixture of resin and polyjo fin/resin at a high fit, so it is more flexible than the upper layer and has an anti-stick effect. Acetate transfer 1〃100m
2 to 10 parts of polypropylene resin per 1 part,
Since it is a mixture of filler and foaming agent, it is easy to mix ethylene vinyl acetate resin and filler! ! ,! There is no sagging phenomenon called the so-called "loincloth phenomenon" when winding up to zero during manufacturing, and the winding is correct.
Although the upper layer is given a suitable amount of flexibility, it has only one printability and does not lose its role as a substrate, and the feet may sink too much when you put your feet on it. There is no such thing.
