  • Multilayer composite rubber-plastic foam insulation material and preparation method thereof
    Patent number: 11498309
    Abstract: The present invention discloses a multilayer composite rubber-plastic foam insulation material and a preparation method thereof. The composite rubber-plastic foam insulation material includes a two-layer structure; the two-layer structure includes an insulation layer and a first functional layer; the insulation layer and the first functional layer are both made of a rubber-plastic foam material; the first functional layer and the insulation layer are integrally molded by blending extrusion and vulcanization foaming, and the first functional layer and the insulation layer form an integral structure. The multilayer composite rubber-plastic foam insulation material provided by the present invention adopts a vulcanization foaming integral molding process, and not only ensures the thermal insulation property of the insulation layer, but also gives the functional layer corresponding functions by selecting different functional polymers, thereby satisfying a variety of personalized needs in engineering applications.
