THE PREPARATION OF LUBRICATING RESIN SOLUTION HAVING HIGH SURFACE LUBRICATING , NON-CORROSIVENESS, AND GOOD COATING PROPERTIES AND THE PREPARATION METHOD OF SURFACE TREATMENT OF STEEL PLATE BY USING THEREOF

摘要

PURPOSE: A process for preparing thermosetting aqueous lubricating resin is provided for accomplishing excellent surface lubricating ability, corrosion-resistance and painting ability by preparing the aqueous epoxy-graft acrylate resin by means of radical polymerization of epoxy portion and acrylic portion in a weight ratio of 1:1-5. CONSTITUTION: The process comprises the first step of preparing the aqueous epoxy-graft acrylate resin by means of radical polymerization of epoxy portion and acrylic portion in a weight ratio of 1:1-5; the second step of neutralizing the resin with the specific neutralizing agent; the third step of diluting the solution with water to have 10-35 wt.% of solid content; the fourth step of adding 5-25 weight parts of the lubricating agent, 10-80 weight parts of silica, 0.05-2 weight parts of silane coupling agent and 4-35 weight parts of hardening agent to the resultant solution based on total 100 weight parts of resin solid content.
