The invention discloses a skin material for an airplane and a preparation method of the skin material, and relates to the technical field of paint layers. The paint comprises a base material, a primer, a colored paint and a varnish, the primer is a modified epoxy primer with improved low-temperature flexibility and corrosion resistance, the colored paint is a modified polyurethane colored paint with improved weather resistance, rigidity and flexibility, and the varnish is a polyurethane varnish. The high-performance finishing paint resin is prepared by introducing a flexible chain segment modified epoxy primer and introducing a six-membered ring structure group through a hydroxyl ring-opening graft polymerization method; the influence rule of flexible soft ether bonds and combined amide groups on the comprehensive performance of epoxy resin and the influence rule and enhancement mechanism of six-membered ring structure groups and organic silicon intermediates on resin polymerization reaction, resin film-forming performance and comprehensive performance of paint are disclosed for the first time, and polymerization processes such as types and dosage of dihydric alcohol are explained. The reaction temperature and the like are related to the comprehensive performance of the paint film.
