The invention discloses a water-based color-adding UV coating with a long recoating interval, comprising the following two groups of components A and B. The water-based color-adding UV coating formed by mixing the A and B components is applied to ABS and PC substrates. Or when applied on metal substrates, it can effectively extend the recoating interval to 48 hours, and the VOC of the coating is 200-260g/L, which also meets environmental protection requirements. It overcomes the shortcomings of the traditional spray solvent-based UV additive paint whose VOC can no longer meet the requirements of ≤550g/L in GB/T30981‑2020 and the short recoating interval of the existing water-based UV additive paint.

The invention discloses a bonding process between a metal base material and a glass base material, which comprises the following steps: coating the surface of the metal base material with a layer of polymer coating, coating the surface of the glass base material with a layer of ink coating, and placing a glue film between the metal base material and the glass base material, and the adhesive film is respectively combined with the polymer coating and the ink coating. According to the bonding process between the metal base material and the glass base material, hydroxyl, carboxyl and isocyanato which are contained on a main chain of thermoplastic polyurethane resin in the adhesive film respectively react with a polymer coating on the surface of the metal base material and an ink coating on the surface of the glass base material; the binding force between the adhesive film and the metal base material and the binding force between the adhesive film and the glass base material are respectively enhanced, so that the connecting strength between the metal base material and the glass base material is improved.
