    摘要： Plastic foam has excellent heat insulation properties, however, moisture absorption is causing a decrease in the heat insulation, and plastic foam has almost no mechanical strength. Therefore, a heat insulation material that absorbs almost no moisture and has satisfactory strength is desired to appear. According to the present invention, a foam composite with a skin can be formed in one shot by charging plastic powders or minute particles together with polyolefin pellets that can be cross-linked and foamed in a mold, and heating the mold while rotating. The composite absorbs almost no moisture, having satisfactory strength, being excellent as an insulating material. Further, providing a covering of a non-foaming or a slightly foaming material to the pellet of polyolefin that can be cross-linked and foamed, and conducting the forming, foamed granules of preferably 5 to 50 mm largeness as a core, and a covering of a reinforcing member with 0.05 to 0.5 mm thickness for the core, can be formed, which permits that thus obtained shaped body is lightweight, strong, with an equivalent strength to wood that undergoes deformation without breaking when subjected to impact.

    摘要翻译： 塑料泡沫具有优良的隔热性能，但是吸湿性导致绝热性降低，塑料泡沫几乎没有机械强度。 因此，希望出现吸收几乎没有水分并且具有令人满意的强度的隔热材料。 根据本发明，可以通过将塑料粉末或微小颗粒与可以在模具中交联和发泡的聚烯烃粒料一起加入，同时旋转加热模具，一次性形成具有皮肤的泡沫复合材料。 复合材料吸收几乎没有水分，具有令人满意的强度，作为绝缘材料是优异的。 此外，为可交联和发泡的聚烯烃颗粒提供不发泡或稍微发泡的材料的覆盖物，并将成形优选为5至50毫米的发泡颗粒作为核心，以及覆盖物 可以形成具有对于芯部具有0.05至0.5mm厚度的加强构件，这允许由此获得的成形体重量轻，强度高，与受到冲击时经历变形而不破裂的木材相当。
