Embodiment 1
[0035] Preparation method of adhesion enhancing resin
[0036] Take 67 parts of JF-PE-3020 alkyd resin, 20 parts of phthalates, 10 parts of MDI-50 isocyanate monomer, and 3 parts of DY-12 (dibutyltin dilaurate). 60°C, after reacting for 1h, let it stand to room temperature.
[0037] The preparation method of the novel hybrid resin of water-based nano-coating adhesion performance is as follows, and concrete formula is shown in Table 1:
