pcm(預涂金屬)的涂膜主要由有機樹脂(絕緣體)組成,涂膜表面與其它材料(如模具、皮帶輸送機)摩擦時產生靜電,灰塵會粘附在pcm表面。在面涂中加入適當的樹脂和添加劑,能抑制與其它材料摩擦所產生的表面靜電壓,從而防止灰塵的粘附。基于這種想法,開發了抗靜電預涂鋼板,抑制靜電所導致的灰塵粘附。當靜電壓產生和灰塵粘附時,pcm顯示了顯著效果。通過選擇底涂和預處理,也得到了一種不含鉻酸鹽型的pcm。希望這種抗靜電的pcm將來能廣泛應用于各個領域。

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,能夠可靠地抑制由涂層的靜電產生的帶電的pcm。在金屬板的至少一面上形成了涂層的pcm,通過用規定的2種方法的任一種方法,在室溫或者70℃使該pcm進行剝離帶電時所產生的帶電電壓的值分別不到0.15kV或者0.25kV,由此來抑制由各溫度下的靜電引起的障礙的發生。在涂料中,通過相對于全體固形成分的比例含有大于或等于5質量%的異氰酸酯衍生物,特別是異氟爾酮二異氰酸酯(IPDI)衍生物,或者與異氰酸酯衍生物同時以相對于全體固形成分的比例大于或等于1質量%含有烷氧基胺鹽,可使剝離帶電后的帶電電壓降低。

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.
