| description | PROBLEM TO BE SOLVED: To provide a composite sound absorption material and sound absorptive interior material that can easily adjust the air permeability and can improve the sound absorption performance by adjusting the air permeability.SOLUTION: A composite sound absorption material 1 includes a synthetic resin foam layer 3 on the surface of a fiber substrate 2. The synthetic resin foam layer 3 includes synthetic resin emulsion mixed with thermal expandable micro capsules. The thermal expandable micro capsules are expanded by heating the synthetic resin emulsion, the size of the clearance formed between the thermal expandable micro capsules can be changed in response to the expansion degree of the thermal expandable micro capsules, thereby adjusting the air permeability to a desired value.SELECTED DRAWING: Figure 1
【課題】 通気度を容易に調節することができ、該通気度の調節によって吸音性能の向上を図ることができる複合吸音材料および吸音性内装材を提供する。【解決手段】 繊維基材２の表面に合成樹脂発泡層３を形成してなる複合吸音材料１であって、合成樹脂発泡層３には、熱膨張性マイクロカプセルが混合された合成樹脂エマルジョンを使用し、該合成樹脂エマルジョンを加熱して該熱膨張性マイクロカプセルを膨張させるとともに、該熱膨張性マイクロカプセルの膨張度合いに応じて該熱膨張性マイクロカプセル同士の間に形成される隙間の大きさを変えることにより、通気度が所望値となるように調節される。【選択図】 図１ |
