    • PROBLEM TO BE SOLVED: To impart a rust preventive effect (discoloration prevention and corrosion prevention) to a copper or copper alloy sheet or strip by subjecting the copper or copper alloy sheet or strip to rust preventive treatment by benzotriazole or its derivative and simultaneously to prevent the deposition of green powder on a wiping pad at the time of press working, such as punching.
      SOLUTION: The surface of the copper or copper alloy sheet or strip is subjected to the rust preventive treatment by the benzotriazole or its derivative and thereafter a press oil or rolling mill lubricant is applied thereto. The oil of a viscosity 1 to 30 cst is preferably applied thereto at a coating weight of 0.01 to 10 mg/m
      2 . By the coating application of the oil, the dislodgment of the rust inhibitive film by the benzotriazole from the surface of the sheet or strip is substantially prevented, the generation of the green powder is suppressed and the deposition of the green powder of the wiping pad is prevented.

    • 要解决的问题:通过对铜或铜合金板或带进行苯并三唑或其衍生物的防锈处理,使铜或铜合金板或带材具有防锈效果(防变色和防腐蚀) 同时防止在冲压加工时诸如冲压之间的绿色粉末沉积在擦拭垫上。 解决方案:通过苯并三唑或其衍生物对铜或铜合金板或带材的表面进行防锈处理,然后对其施加压榨油或轧机润滑剂。 粘度为1〜30cst的油优选以0.01〜10mg / m 2的涂布重量施加于其上。 通过油的涂布,基本上防止了苯并三唑从片材或带的表面脱落防锈膜,抑制了绿色粉末的产生,擦拭垫的绿色粉末的沉积是 预防。 版权所有(C)2005,JPO&NCIPI
