自1979年日本对汽车实行噪声控制以来,各钢铁公司开发出夹层滞振钢板。它是在两层钢板之间夹着一层树脂的新材料。钢板可采用冷轧板、酸洗板、镀锌板、彩色涂层板或不锈钢板。夹层树脂可采用聚丙烯或尼龙,使用温度为80～100℃时,树脂层厚度为50～100μm,常温使用时为50～500μm。滞振钢板可直接利用夹层树脂的粘性予以粘接,也可以采用粘结剂。加热粘结可提高粘结力。有的厂家先将树脂涂刷在一层钢板上,再将另一层钢板压贴上去。夹层钢板在平直状态下的滞振系数为0.1～0.5,与夹层之间的粘结力呈反比,并与夹层树脂的类型有关。经变形加工成不同构件时,滞振系数
Since 1979, when Japan implemented noise control on automobiles, each steel company developed a sandwich-type vibration-resistant steel plate. It is a new material with a layer of resin sandwiched between two layers of steel. Cold-rolled steel plate can be used, pickling plate, galvanized sheet, color coated plate or stainless steel plate. The interlayer resin may be polypropylene or nylon. When the temperature is from 80 to 100 ° C, the thickness of the resin layer is from 50 to 100 μm and from 50 to 500 μm at room temperature. Vibrating steel can be directly laminated resin viscosity to be bonded, you can also use a binder. Heat bonding can improve the adhesion. Some manufacturers first brush the resin in a layer of steel, and then another layer of steel pressure paste up. The lagging coefficient of the sandwich plate in the flat state is 0.1-0.5, which is inversely proportional to the adhesive force between the two layers and is related to the type of the sandwich resin. Deformation processed into different components, the vibration coefficient
