BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip dust mat having a high durability, which is to be laid on a floor such as a corridor or an entrance of a room where tiles, linoleum, carpets, etc. are constructed, and a method for producing the mat. .

[0002]

2. Description of the Related Art In the prior art, a releasable sheet is placed on a press table for vulcanization, and an unvulcanized rubber sheet is placed on it.
On this unvulcanized rubber sheet, rubber latex is applied to a tufted pile base fabric and placed on top of it, and a releasable sheet is laid on top of it. The vulcanized rubber sheet was vulcanized, the upper releasable sheet was peeled from the vulcanized rubber sheet, and then the rubber sheet was released from the lower releasable sheet.

However, with this technique, it is possible to obtain a dust mat in which a rubber sheet is provided with a wrinkle, but when this dust mat is laid on the floor such as a corridor or a room entrance where tiles, linoleum, carpets, etc. are constructed. However, there was a drawback of walking and sliding on the floor.

Good results with excellent durability were obtained. The above is the case where the continuous grid-like continuous linear grooves 4 are provided in communication with the outer periphery to form the trapezoidal trapezoidal protrusions 5, but the circular linear grooves are provided in communication with the outer periphery, When a circular trapezoidal protrusion is formed, when the trapezoidal protrusion has a diameter of 5,0 mm to 20,0 mm and a height of 0.2 mm to 0.6 mm, tiles, linoleum,
The non-slip dust mat laid on the floor such as a corridor with a carpet or the entrance of a room did not slip and move on the floor by walking, and good results with good durability were obtained.

FIG. 3 is an explanatory view of the manufacturing method according to the present invention, in which a releasable sheet 11 is placed on a press die 10 and formed on the releasable sheet 11 with glass fiber or the like. The net-like frame body 12 made of continuous grid-like filaments is placed, the unvulcanized rubber sheet 13 is placed thereon, and the pile fabric 2 is tufted onto the unvulcanized rubber sheet 13. It was disassembled and shown that the releasable sheet 14 was placed on top of it, and pressed by the press die 15 from above. Then, the unvulcanized rubber sheet 13 is vulcanized at 140 ° C. to 160 ° C. for 5 minutes to 20 minutes, the releasable sheet 14 is peeled from the vulcanized rubber sheet, and then the releasable sheet. The vulcanized rubber sheet is released from 11 and the frame 12.

The releasable sheets 11 and 16 have heat resistance that does not melt under the vulcanization conditions of the unvulcanized rubber sheet 13 and can be easily peeled from the rubber sheet after vulcanization. Made to a thickness of about 0.2 mm. Although glass fiber is used in this embodiment, it may be made of polyfluorinated ethylene resin.

FIG. 4 is a plan view of the frame body 12. The frame body 12 has heat resistance so that it does not melt under the vulcanization condition of the unvulcanized rubber sheet 13, and the rubber body after vulcanization is treated. It is made of a material that has the property of being easily peelable from the sheet. In this embodiment, the diameter is about 0.2 mm to 0.6
mm of glass fiber was used. And the rubber sheet 1
In the embodiment of the non-slip dust mat having a thickness of 20 mm, the vertical rod 6 and the horizontal rod 7 are connected by the contact points 9,
The size of the voids 8 was set to a linear mesh body having a mesh of 5,0 mm to 20,0 mm square. Further, the trapezoidal protrusion 5 of the rubber sheet 1 can be formed in a circular shape by forming the void 8 into a circular shape having a diameter of 5,0 mm to 20,0 mm. The frame 12 can be used even if it is formed of an aluminum plate.

During the vulcanization treatment, it is preferable that the releasable sheet 11 and the frame body 12 do not move, and the releasable sheet 11, the frame body 12 and the unvulcanized rubber sheet 13 are integrally formed. Make arrangements so that it can be moved. In addition to natural rubber, so-called synthetic rubber is used for the unvulcanized rubber sheet 13, and its thickness is preferably around 5,0 mm. It is reduced by vulcanization, but rubber latex is applied to the back surface. Adhesion with the rubber sheet 13 is made good. A non-woven fabric made of synthetic fiber such as polyester is used for the base fabric 3, and synthetic fiber such as crimped nylon fiber, vinylon fiber, acrylic fiber, natural fiber such as cotton fiber, or these 2 is used for the base fabric 3. The pile yarn 2 made of one or more kinds of blended fibers is tufted to form a dust mat surface.

[00010]

As described above, according to the present invention, a vulcanized rubber sheet having a tufted pile base fabric attached to the surface thereof has a continuous checkerboard line or a continuous line on the back surface of the rubber sheet. It is characterized in that a shallow linear groove such as a circular line is provided so as to communicate with the outer periphery to form a trapezoidal protrusion such as a square or a circle. When laid on the floor such as the entrance and walking on the floor, the air between the rubber sheet and the floor escapes through the linear groove, and the trapezoidal protrusion adheres to the floor. Therefore, the dust mat does not slip on the floor and move even when walking strongly.

Further, a releasable sheet is placed on a vulcanizing press die, and a continuous cross-shaped line or a continuous circular line formed of glass fiber or the like is placed on the releasable sheet. Place the frame body on which the unvulcanized rubber sheet is placed, and on top of this unvulcanized rubber sheet, place the tufted base fabric of pile yarns, stack the releasable sheet on it, and press from above. The unvulcanized rubber sheet is vulcanized by pressing with a mold and heating, the upper releasable sheet is peeled from this vulcanized rubber sheet, and then the lower releasable sheet and the rubber sheet from the frame body. Even if it is characterized in that the dust mat is removed, it is possible to efficiently and easily manufacture the dust mat which is vulcanized and non-slip at the same time by a simple operation of placing the mesh frame body.
