COATING SOLUTION FOR SURFACE TREATMENT HAVING STABILITY OF FRICTION COEFFICIENT, CORROSION RESISTANCE, AND ECO-FRIENDLY PROPERTY, AND METHOD FOR PREPARING COATING LAYER USING SAME COATING SOLUTION

摘要

The present invention relates to a coating solution for surface treatment having stability of friction coefficient, corrosion resistance, and eco-friendly property, and to a method for preparing a coating layer using the coating solution. More specifically, a coating solution according to an embodiment of the present invention contains 13-17 wt% of (3-aminopropyl)triethoxysilane, 65-75 wt% of dipropylene glycol, 4-6 wt% of stearic acid, 13-15 wt% of tetraethoxysilane, 0.5-1 wt% of tetrabutyle titanate, and greater than 0 wt% and up to 0.5 wt% of tetraisopropyl titanate, and thus has an effect of simultaneously satisfying the stability of friction coefficient, corrosion resistance, and eco-friendly property.
