Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is mainly used to prevent slipping on smooth surfaces, specifically to prevent slipping of rugs on floors, to prevent objects placed on table surfaces, etc. This invention relates to a non-slip sheet used for and a method for manufacturing the same.

[Conventional technology]

Method: The back side of carpets, entrance cloaks, etc. that are laid on smooth floors such as linoleum floors, mortar floors, concrete floors, etc. should be treated with anti-slip treatment, such as embossed or lined with foam rubber sprayed. However, a sufficient anti-slip effect cannot be expected due to the lack of flexibility and the roughness of the formed irregularities. Furthermore, if the rug is laid in a state where there is surplus space, it will slip considerably on the floor surface if it is simply laid down, resulting in the rug falling over when a person steps on it or causing the rug itself to shift from its predetermined position.

In particular, if moisture or dirt is present between the rug and the floor,
These act to promote slippage, and the slippage becomes noticeable. For this reason, it is generally fixed with an adhesive that is applied directly, or if it is necessary to remove it (9, 1), it is temporarily fixed using double-sided adhesive tape, etc. This is the current situation.

[Problem that the invention seeks to solve]

However, according to the above-mentioned conventional means, when washing the rug or cleaning the floor when the rug gets dirty, the adhesive part is removed! ! , 1), and for this reason, it not only damages the floor surface or rug, but also requires a lot of effort to remove and is very difficult to clean.Also, adhesive tape, Anti-slip means using suction cups or the like have a relatively strong adsorption force in the direction perpendicular to the floor surface, but extremely weak resistance in the direction parallel to the floor surface. There have been problems such as the presence of the anti-slip member being transmitted through and the surface bulging due to the thickness of the anti-slip member, resulting in an unsightly appearance.

Also, for objects placed on a smooth table (th1)2, they will slide and roll off the table E due to a slight external force (1).
I fell down and broke! There were drawbacks that could lead to scandals such as

The present invention has been made in view of the above-mentioned conventional drawbacks, and is intended to achieve an excellent anti-slip effect by being used as the material of the product itself or combined with the product requiring anti-slip properties, and to reduce the added load. The object of the present invention is to provide an anti-slip sheet and a method for manufacturing the same, which can reliably discharge the fluid present on the contact surfaces by pressure and achieve excellent anti-slip effects by completely adhering the surfaces to each other.

[Means for solving problems]

The anti-slip sheet that achieves the above object is characterized by having a thin foamed rubber layer with open cells and fine surface irregularities formed on the sheet surface,
The anti-slip sheet is made by combining sheets that are supplied separately so that they face each other at a corner at a predetermined distance during the transportation process, and then inserting an open-cell foamed rubber material that has been mixed and stirred in advance between the two sheets. Manufactured by sandwiching and passing through a vulcanization device to form an open-cell rubber layer, and then dividing the open-cell rubber layer in the layer direction to form a finely uneven surface on each sheet surface. It will be done.

[Action of the invention]

The non-slip sheet of the present invention having the structure described above can be made by making the finely uneven surface formed by dividing the open cells face a smooth surface such as a floor surface, or by folding it in half so that the finely uneven surface becomes the front surface. The sheets may be used so that one side is in contact with the floor and the other side is in contact with the back side of the rug being laid down, or the lack of surgical gloves, etc. (used as raw material sorting for products that require non-slip properties, On one side, a thin foam rubber layer with open cells and a finely textured surface is formed.
When placed on the floor and subjected to a load, it significantly reduces the frictional resistance between the political commercial and the floor.

That is, when the load is negative 1;
・As it is compressed, air and moisture existing between the surface of the thin foam rubber layer and the floor surface or contained in the surface of the foam rubber layer are pushed out, and a lubricating film is formed between the two by the fluid. The convex portions and concave portions of the flexible finely textured surface are smoothed and come into complete contact with the floor surface.

In addition, the second invention, which is a method of manufacturing the anti-slip sheet of the present invention, involves forming a foamed rubber layer of open cells of a predetermined thickness in close contact between the separately supplied sheets, and then peeling off each sheet. Then, the open-cell foam rubber layer is divided into two layers and adhered to the surface of each sheet, and each sheet has a continuous band of two anti-slip sheets with finely textured surfaces. began to be produced.

〔Example〕

An embodiment of the anti-slip sheet of the first invention is shown in FIG. 1. That is, on one side of a sheet 1 made of non-woven fabric, which is a type of breathable sheet, a thin open-celled foamed rubber layer is formed by dividing an open-celled rubber layer in the layer direction so that the cut surface has fine irregularities 2. 3 was formed.

FIG. 2 shows an embodiment of the method for manufacturing anti-slip sheets 1 to 1 according to the second invention, in which a sheet 1 made of a long woven or non-woven fabric wound around a supply drum 4.4°, are continuously transported while being guided by guide rolls such as 5.5 degrees, and the transported sheets 1.1" are held between clip bins installed at equal intervals on the chain of the transport device section, and It is automatically fed into the vulcanizer 8 by passing it between the support table 6 and a knife 7 installed opposite thereto.Then, in front of the knife 7, the open-cell foamed rubber material 9, which has been mixed and stirred in advance, is foamed. The open-cell foamed rubber material 9 is supplied from the stirring tank 10 onto the base fabric 2', and after forming the foamed rubber layer 3 with a thickness of about 1 m by the knife 7, it is passed into the vulcanizer 8. This is then vulcanized and bonded.

Then, peel off the vulcanized and bonded integrated layer sheet so that the central foam rubber layer 3 is divided into two parts (see Figure 3).
, by winding each winding drum at an angle of 12.12 degrees.

Note that the sheets 1.1'' do not necessarily have to be made of the same material; for example, one may be made of non-woven fabric and the other may be made of woven fabric.
The foamed rubber layer 9 on the sheet 1 is vulcanized and bonded to the sheet 1.1' in a state that penetrates between the fibers, and its thickness is approximately 0.1 to 1.1 mm so that the remaining thickness upon peeling is average and constant. .51
It is set within a certain range, and nonwoven fabrics such as nylon, polyester, rayon, and polyethylene are suitable as the sheet to be used in terms of cost. Also,
The open-cell foamed rubber material 9 that is mixed and stirred in advance is, for example, natural rubber latex ---------------------50 styrene-butadiene latex. -5
0 Nonionic stabilizer 1.0 Sulfur Yellow
1.5 zinc white
3.0 Ammonium oleate
1.0 Light stabilizer 0.5
Thickener: These are mixed and stirred in small amounts, and a nonionic stabilizer is used to prevent coagulation due to stirring.

In addition, when forming open-cell foamed rubber layers on both sides of a sheet, three sheets are supplied, and after forming an open-cell foamed rubber layer between each sheet, the rubber layers are layered in the layer direction. By dividing, two sheets with non-slip on one side and a sheet with non-slip on both sides are produced.

〔Effect of the invention〕

The anti-slip sheet of the present invention having the above structure has a thin foam rubber layer with open cells and fine surface irregularities formed on one side of the sheet, so that the surface of the thin foam rubber layer and the floor surface are Air and water fluids interposed between them escape through the open-cell rubber layer, and the convex and four parts of the flexible finely textured surface are smoothed and come into close contact with the floor surface. Excellent anti-slip effect is achieved not only inside but also underwater. In addition, due to this excellent anti-slip effect, it is possible to sufficiently prevent rugs from slipping even without adhesively fixing them to the floor, making anti-slip treatments unnecessary, and by adhesively fixing them to the floor. The unsightly appearance that occurred when removing the rug will also be eliminated. Furthermore, since the anti-slip sheet of the present invention is composed of a thin sheet and a thin open-cell foam layer, even if it is laid under a rug, etc., the rug may float due to its thickness, or it may be difficult to see through. It is possible to provide a non-slip sheet that is stylish and usable without causing any inconvenience.

Furthermore, the anti-slip sheet of the present invention can be advantageously used not only as a non-slip rug, but also as a raw material for products that require anti-slip properties.

Furthermore, in the anti-slip sheet of the present invention, after forming an open-cell foam rubber layer of a predetermined thickness in close contact between the separately supplied sheets, the open-cell foam rubber layer is formed by applying '/il+dross for each sheet. is divided into two layers and adhered to the surface of each sheet, so that two bands of anti-slip sheets with each sheet having a finely uneven surface are produced simultaneously and continuously. The manufacturing efficiency is extremely high and the cost is extremely low.
