動性にしたものである。In the present invention, the ultra-high molecular weight PE sheet formed by the shaving method is a heating and press sintering of an ultra-high molecular weight polyethylene powder to produce a columnar molded product, and the molded product is formed into a cylindrical shape. It refers to a sheet or film cut in a thin direction. The display material of the present invention is formed from a composite sheet in which an ultra-high molecular weight PE sheet formed by shaving on both sides of a polyethylene colored sheet mixed with a colored powder is heat-bonded. The polyethylene colored sheet is prepared by mixing a colored powder with heat-flowable low-molecular-weight polyethylene such as low-density polyethylene obtained by a normal high-pressure method or high-density polyethylene obtained by a low-medium-pressure method, and molding this mixture into a sheet. Then, the obtained sheet is irradiated with an electron beam to be crosslinked to make it hard to flow.

さが２０〜２００μｍの範囲のものがよい。Further, the polyethylene colored sheet needs to be made hard to flow by electron beam irradiation. This is because if the liquid is not made hard to flow, it is fluidized when thermally bonded to the rubber product under pressure, and the display form such as characters and designs disappears. The irradiation condition of the electron beam is not particularly limited, but it is preferable to set the irradiation dose to 1 to 20 Mrad. This polyethylene-colored sheet is used to form a display such as a character or a design, and when used, is formed into a composite sheet having both surfaces sandwiched between two ultra-high molecular weight PE sheets and thermally bonded. This ultra-high molecular weight PE sheet is formed by a shaving method, has excellent adhesiveness to rubber, and is flexible and easily bent.
Moreover, because of its high crystallinity, it has high tensile strength and has many excellent properties such as dimensional stability, gas permeability resistance, and water resistance. Such an ultrahigh molecular weight PE sheet is desirably made of polyethylene having a molecular weight of at least one million and has a thickness in the range of 20 to 200 μm.

法である。There are two methods of using the composite sheet to label a rubber product, one in which the rubber product is not vulcanized, and the other in which it is performed after vulcanization. In the first method, a colored sheet made of a heat-flowable polyethylene mixed with a colored powder and made hard to flow by electron beam irradiation is used.
A composite sheet that is heat-bonded between two ultra-high molecular weight PE sheets is cut out into characters, designs, etc. and used as a display, and this display is attached to the surface of the unvulcanized rubber product before vulcanization, This is a method in which the unvulcanized rubber is bonded simultaneously with vulcanization.

る。According to a second method of the present invention, a display material produced in the same manner as in the above-mentioned first method and another ultra-high molecular weight PE sheet are attached to an unvulcanized rubber surface of a rubber product before vulcanization. In this method, the ultra high molecular weight PE sheets are bonded together with the rubber product to which the ultra high molecular weight PE sheet is bonded at the same time as the vulcanization, and the ultra high molecular weight PE sheets are superposed on each other and heat-sealed. According to the present invention, by thermally bonding an ultrahigh molecular weight PE sheet in advance, even if the rubber product has been vulcanized, it is possible to strongly thermally bond the mark. Further, as in the case where the rubber product is unvulcanized, a rubber composition containing a raw rubber having a critical surface tension γc of 25 to 35 mN / m can be used. When the rubber product has been vulcanized, the above-mentioned critical surface tension γc increases due to the crosslinking of the raw rubber, and the adhesiveness to the ultrahigh molecular weight PE sheet decreases, but the raw rubber having a γc in the range of 25 to 35 mN / m is used. The composite sheet prepared as described above can be directly heat-bonded to a vulcanized rubber product containing.

The vulcanization temperature or the heat fusing temperature at the time of heat fusing with a high molecular weight PE sheet is such that the unvulcanized rubber can be vulcanized and the melting point (125 ° C.) or more of the ultrahigh molecular weight PE sheet is higher, preferably 130 ° C. The above temperature may be sufficient. If the temperature is too high, the ultra-high molecular weight PE sheet may be thermally degraded.

A colored sheet formed from heat-flowable polyethylene mixed with a colored powder, processed into a non-flowable colored sheet by electron beam irradiation, and two colored sheets formed by shaving out the colored sheet. Along with producing a composite sheet sandwiched between high molecular weight polyethylene sheets and thermally bonded,
Characters, designs and the like are cut out from the composite sheet, the display is attached to the unvulcanized rubber surface of the rubber product before vulcanization, and the display is attached to the rubber product to be adhered simultaneously with the vulcanization of the unvulcanized rubber.

A colored sheet formed from heat-flowable polyethylene mixed with colored powder, processed into a non-flowable colored sheet by electron beam irradiation, and the colored sheet is cut out and molded into two super-colored sheets. While preparing a composite sheet sandwiched between high-molecular-weight polyethylene sheets and thermally bonded, and cutting out characters, designs, and other indications from the composite sheet, another ultra-vulcanized rubber surface is applied to the unvulcanized rubber surface of the rubber product before vulcanization. A high-molecular-weight polyethylene sheet is laminated, and a rubber product is produced by heat-bonding simultaneously with the vulcanization of the unvulcanized rubber, and the surface of the ultra-high-molecular-weight polyethylene sheet of the display object is attached to the surface of the ultra-high-molecular-weight polyethylene sheet of the rubber product. How to attach a label to a rubber product to make it adhere.
