Abstract: A waterproof screw includes a screw member including a head portion and a shank portion and a sealing material covering the circumference of the shank portion. In the sealing material, the tackiness of a surface at the outer side in a radial direction of the shank portion is lower than that of a surface at the inner side in the radial direction thereof and the inner side in the radial direction of the sealing material has a shear storage elastic modulus G′ at 25° C. measured at a frequency of 1 Hz of 50000 Pa or less.

Abstract: To be provided is a foam waterproofing material superior in waterproofness and flexible enough to be compatible with further minute clearance.The foam waterproofing material according to the present invention is a waterproofing material including a foam having a thickness of 0.1 to 1.0 mm, characterized in that the foam has a micro cell structure with an average cell diameter of 10 to 60 μm and an apparent density of 0.01 to 0.060 g/cm3. In the foam waterproofing material, the repulsive load when compressed to 0.1 mm (0.1 mm-compressive repulsion force) of the foam is preferably 0.01 to 0.1 MPa. The foam preferably has a closed-cell structure or a semi-open- and semi-closed-cell structure. In addition, the foam may have a pressure-sensitive adhesive layer on one or both faces thereof. The pressure-sensitive adhesive layer is preferably formed on the foam via a film layer.

Abstract translation: 要提供的是防水性优异且足够灵活以适应进一步微小间隙的泡沫防水材料。 根据本发明的泡沫防水材料是包括厚度为0.1至1.0mm的泡沫的防水材料，其特征在于，泡沫具有平均泡孔直径为10至60μm的微孔结构，并且表观密度 0.01〜0.060g / cm 3。 在泡沫防水材料中，当压缩至泡沫的0.1mm（0.1mm压缩斥力）时的排斥载荷优选为0.01〜0.1MPa。 泡沫优选具有闭孔结构或半开放和半闭孔结构。 此外，泡沫体可以在其一面或两面上具有压敏粘合剂层。 压敏粘合剂层优选通过膜层形成在泡沫上。
