材として好適なポリウレタンフオームとポリオレ
フンの積層体に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a laminate of polyurethane foam and polyolefin suitable for interior materials such as ceiling materials, door trims, instrument panels, and seat skin materials for automobiles and the like.
従来技術
従来、可撓性ポリウレタンフオームとポリオレ

浸し、積層体の柔軟性が悪くなる欠点が生ずる。 When the polyurethane foam has such a large average cell diameter, when it is adhered to a polyolefin sheet, a "pock" pattern appears on the surface, the surface smoothness is poor, and the adhesion between the two is also poor. In an attempt to improve this adhesion, if olefin resin is melt-extruded and applied thickly, or if an adhesive is used, the cells are coarse and a large amount of adhesive is impregnated into the foam, resulting in a disadvantage that the flexibility of the laminate deteriorates. .

ことのない積層体を提供するにある。Purpose of the Invention The present invention aims to eliminate the drawbacks of conventional laminates of polyurethane foam and polyolefin.
To provide a laminate that does not generate patterns, has a smooth surface, can be easily bonded even with a thin polyolefin layer, and does not impair flexibility.

明を完成した。Structure of the Invention As a result of research to achieve the above object, the present inventors have found that the conventional drawbacks can be overcome by reducing the average cell diameter of the polyurethane foam within a certain range. The present invention was completed based on this knowledge.

タンとポリオレフインの積層体にある。 The gist of the present invention is a laminate of polyurethane and polyolefin in which an olefin polymer layer is formed on the surface of a fine-cell flexible open-cell polyurethane having an average cell diameter of 90 to 380 microns.

しくない。 The polyurethane used in the present invention is a flexible open-cell polyurethane, and its average cell diameter must be 90 to 380 microns. If the average cell diameter is less than 90μ, the adhesion with polyolefin will be poor, and if it exceeds 380μ, “pockmarks” will occur on the surface and the surface smoothness will deteriorate, which is not preferable.

る。 In the present invention, it is also possible to use semi-cut pieces of polyurethane foam with self-skin on both sides as the polyurethane foam. In this case, an olefin polymer layer is usually formed on the cut half surface, that is, the surface other than the skin surface. A laminate using this self-skinned polyurethane foam is difficult to slip between the foam and the floor due to the adhesiveness of the self-skin, and is therefore suitable as a carpet underlay.

ても充分被着体との接着力が保たれかつ表面が高
度に平滑である。 Conversely, it is also possible to form an olefin polymer layer on the skin surface. In this case, apply adhesive to the skin surface. Since the adhesive is a skin surface, it is not absorbed by the foam, so even if it is applied thinly, sufficient adhesion to the adherend is maintained and the surface is highly smooth.

Any method may be used, including (3) heating a pre-obtained polyolefin polymer film or sheet and pressing it onto the polyurethane foam.
