    • The invention provides a steel plate reinforcing sheet that can provide improvement in adhesiveness as well as in reinforcement. In the steel plate reinforcing sheet comprising a restricting layer 1 and a reinforcing layer 2, the reinforcing layer 2 is formed of foam composition comprising styrene synthetic rubber, aromatic epoxy resin, and a foaming agent. Also, in the steel plate reinforcing sheet, a total thickness of the restricting layer 1 and reinforcing layer 2 is not more than 3.5 mm, and the steel plate reinforcing sheet is formed to have adhesion at 5° C. to an oiled, cold-rolled steel plate of not less than 2.0N/25 mm and also has bending strength of not less than 18N after heated at 160° C. for twenty minutes. This can satisfy both of the adhesion and the reinforcement which have been incompatible with each other hitherto, ensuring both sufficient adhesion to the steel plate and sufficient reinforcement of the same steel plate. Thus, this steel plate reinforcing plate, when adhesively bonded to a steel plate 4 used in a variety of industrial machines properly and then foamed, can provide an effective reinforcement of the steel plate 4 by forming the steel reinforcing plate bonded to the steel plate.
    • 本发明提供一种能够提高粘合性和增强性的钢板增强片。 在包含限制层1和增强层2的钢板增强片中,增强层2由包含苯乙烯合成橡胶,芳族环氧树脂和发泡剂的泡沫组合物形成。 此外,在钢板增强片中,限制层1和加强层2的总厚度不大于3.5mm,并且钢板增强片形成为在5℃下与含油, 轧制钢板为不小于2.0N / 25mm,并且在160℃加热二十分钟后还具有不小于18N的弯曲强度。 这可以满足迄今为止彼此不相容的粘合和增强两者,确保对钢板的充分粘合性和对同一钢板的充分加固。 因此,该钢板增强板在与各种工业机械中适用然后发泡的钢板4粘接时,可以通过形成与钢板接合的钢加强板来提供钢板4的有效加固。
