Therefore, taking advantage of the positive effects of multilayer structure of a-zirconium phosphate (α-ZrP) on the anti-aging properties of coatings, organic–inorganic composite materials based on a-ZrP were synthesized. Firstly, a-ZrP was synthesized by a hydrofluoric acid precipitation method. Then, CT-ZrP was prepared by a-ZrP, pre-intercalated successively with cholamine and cetyltrimethylammonium bromide (CTAB). The synthesized CT-ZrP was then used for synthesizing urushiol-titanium polymer/ZrP composite coatings (M-ZrP) through intercalation. The results of XRD, TEM, and FTIR proved the successful intercalation of α-ZrP and the loss of layering M-ZrP composite coatings in the process of exfoliation. TG results showed that the thermal stability of M-ZrP3 (3 wt% CT-ZrP) was higher than that of urushiol-titanium polymer (UTP). After 1000 h of accelerated aging, 3 wt% of CT-ZrP could significantly improve the anti-aging property of the UTP coating, and the maximum rate of gloss loss was the lowest (5.9%).
