COMPOSITION FOR RUST-PREVENTIVE AGENT, AQUEOUS RUST-PREVENTIVE LUBRICANT AND PROCESSING METHOD OF METAL MATERIALS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To develop a composition for a rust-preventive agent exhibiting excellent rust preventive performance by mixing with an aqueous lubricant used in processing such as cutting, machining, drilling, polishing of metals, to provide an aqueous rust-preventive lubricant having excellent rust-preventive lubrication performance and stability by blending with a rust-preventive agent and a lubricant in appropriate amounts, and to provide a rust-preventive lubrication method and a processing method of metals by using the aqueous rust-preventive lubricant.;SOLUTION: The composition for a rust-preventive agent has a synergistically improved rust-preventive performance by containing gluconate and/or heptogluconate, and a saccharide compound as rust-preventive components, and exhibits outstanding rust-preventive performance on aluminium materials or aluminum alloy materials in the case of processing metal materials.;COPYRIGHT: (C)2014,JPO&INPIT
