きる場合は、必然的ではない。However, when the thickness of the adhesive layer is made to be a thin layer of less than 0.5 mm, it is not necessary if migration of auxiliary materials such as a vulcanizing agent from the rubber substrate 1 is expected.
■上記接着剤層の厚みは、0.1〜2mmとする。(2) The thickness of the adhesive layer is 0.1 to 2 mm.

If it exceeds m, the material cost will increase and the properties of the rubber base will be lost, which is undesirable.

The thickness of the decorative coating layers 3A and 3B after heating and gelling is 50 to 2000 μm, which is almost the same as the coating thickness before gelling.

A rubber laminate in which a design coating layer made of PVC gel is formed on a rubber base made of DM, and between the rubber base and the design coating layer, 40 to 80% by weight of NBR and EPDM.
An adhesive layer consisting of a blended rubber or a rubber compound thereof having a composition of 20 to 60% by weight and SBR of 0 to 35% by weight is interposed, and short fibers or natural leather powder are interposed in the PVC keloid. Since they are mixed to form a fabric-like or leather-like design coating layer, the following actions and effects are achieved.

It required a lot of man-hours such as attaching the cloth and curing the adhesive. On the other hand, the rubber laminate with a designed coating layer of the present invention does not require such a time-consuming pre-treatment, but can be made by simply interposing an adhesive layer with a specific blended rubber or its rubber compound. Good adhesion can be ensured between the rubber base and the decorative coating layer. Also, there is no need to attach cloth or leather. Therefore, a cloth-like or leather-like design surface can be formed with good productivity on the EPDM rubber substrate.

) (width 35mm x thickness 4m)
mt) was extruded (conditions: extrusion speed 5 m/min). Next, the top surface of the extrudate (rubber base) was coated with a PVC paste (after vacuum degassing) mixed with short fibers having the formulation shown in Table 3 to a film thickness of 1 mm using a shower coating method. A design coating layer (PVC paste layer) is formed, and the extrudate is carried into a hot air tank, and the paste layer is heated to gel on the vulcanized mold of the rubber base 1 and adhesive layer under the conditions of 200°C x 1O min. It was done at the same time.
