pcm(预涂金属)的涂膜主要由有机树脂(绝缘体)组成涂膜表面与其它材料(如模具皮带输送机)摩擦时产生静电,灰尘会粘附在pcm表面在面涂中加入适当的树脂和添加剂能抑制与其它材料摩擦所产生的表面静电压从而防止灰尘的粘附基于这种想法开发了抗静电预涂钢板抑制静电所导致的灰尘粘附当静电压产生和灰尘粘附时pcm显示了显著效果通过选择底涂和预处理也得到了一种不含铬酸盐型的pcm希望这种抗静电的pcm将来能广泛应用于各个领域

The coating of pcm (pre-coated metal) is mainly composed of organic resin (insulator). When the coating surface and other materials (such as mold, belt conveyor) produce static electricity, the dust will adhere to the pcm surface.Adding appropriate resin and additives to the surface coating suppresses the static surface voltage caused by friction with other materials to prevent the adhesion of dust.Based on this idea, antielectrostatic pre-coated steel plates were developed to inhibit dust adhesion caused by electrostatic forces.The pcm showed significant effects when static voltage generation and dust adhered.A pcm of the chromate-free type was also obtained by selecting the bottom coating and pretreatment.It is hoped that this anti-static pcm can be widely used in various fields in the future.

提供不大幅度地提高成本,能够可靠地抑制由涂层的静电产生的带电的pcm在金属板的至少一面上形成了涂层的pcm通过用规定的2种方法的任一种方法在室温或者70℃使该pcm进行剥离带电时所产生的带电电压的值分别不到0.15kV或者0.25kV由此来抑制由各温度下的静电引起的障碍的发生在涂料中通过相对于全体固形成分的比例含有大于或等于5质量%的异氰酸酯衍生物特别是异氟尔酮二异氰酸酯(IPDI)衍生物或者与异氰酸酯衍生物同时以相对于全体固形成分的比例大于或等于1质量%含有烷氧基胺盐可使剥离带电后的带电电压降低

Provides little increased cost and can reliably suppress the charged pcm generated by the electrostatic electricity of the coating.When a coated pcm is formed on at least one side of the metal plate, the charged voltage generated by stripping the pcm at room temperature or 70is less than 0.15kV or 0.25kV, respectively, thereby inhibiting the occurrence of obstacles caused by static electricity at each temperature.In the coating, the charged voltage after stripping charged can be reduced by containing the isocyanate derivatives greater than or equal to 5 mass%, especially the isofurone diisocyanate (IPDI) derivative, or simultaneously with the isocyanide derivatives in a proportion greater than or equal to 1 mass% relative to the isocyanide derivative.
