Comparative example 1 differs from example 1 in that chitosan was replaced with gingerol; the gingerol can not generate cross-linking reaction with the coating matrix, the binding capacity of the mildew-proof and shock-resistant coating is deteriorated, the integral film forming capacity is reduced, the adhesive force of the mildew is increased, and the final comprehensive performance is reduced.

Comparative example 2 differs from example 1 in that no chlorogenic acid was added; the mildew-proof and shock-resistant coating has reduced antibacterial groups, so that the mildew-proof capability of the coating is reduced, and the mildew-proof capability of the coating is further reduced.

Comparative example 3 differs from example 1 in that no vinyl benzoate was added; because vinyl benzoate is not added, the stability of macromolecules in the coating matrix is poor, the filling degree is reduced, the heat resistance is reduced, and finally the comprehensive performance of the mildew-proof and shock-resistant coating is reduced.
