COMPOSITE FOAM, AND, METHOD FOR PRODUCING COMPOSITE FOAM
To provide a member which is lightweight and has excellent surface hardness, and a suitable method for producing the same.SOLUTION: A composite foam is provided which comprises a bead foam molded body 21 made from a thermoplastic resin and a foam sheet 22 made from a thermoplastic resin, and has an apparent density of 40-85 kg/m3, and in which the bead foam molded body 21 and the foam sheet 22 are heat-fusion bonded to each other. The foam sheet 22 comprises a first surface 22a heat-fusion bonded to the bead foam molded body 21 and a second surface 22b which is an opposite surface to the first surface 22a, and surface hardness of the second surface 22b is 2B or more by pencil hardness. In the composite foamed body, preferably, the foam sheet is thermoformed, and is a heat molded body having a three-dimensional shape. In the composite foamed body, preferably, the thermoplastic resin which is the same kind as the resin contained in the bead foam molded body is contained in the foam sheet, more preferably, the resin is a polystyrene resin.SELECTED DRAWING: Figure 3
【課題】軽量で優れた表面硬度を有する部材とその好適な作製方法の提供。【解決手段】熱可塑性樹脂製のビーズ発泡成形体２１と、熱可塑性樹脂製の発泡シート２２とを備え、ビーズ発泡成形体２１と発泡シート２２とが熱融着されている複合発泡体であって、見掛け密度が４０〜８５ｋｇ/ｍ3であり、発泡シート２２は、ビーズ発泡成形体２１に熱融着している第１面２２ａと、第１面２２ａの反対面となる第２面２２ｂとを備え、第２面２２ｂにおける表面硬度が、鉛筆硬度で２Ｂ以上である複合発泡体。好ましくは発泡シートには熱成形が施されており、３次元形状を有する熱成形体となっている複合発泡体。好ましくは、ビーズ発泡成形体に含まれている樹脂と同じ種類の熱可塑性樹脂が発泡シートに含まれており、より好ましくは、その樹脂がポリスチレン系樹脂である複合発泡体。【選択図】図３
