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.

    本发明公开了一种飞机用蒙皮材料及其制备方法,涉及漆层技术领域。本发明包括基材、底漆、色漆和清漆,底漆为提高了低温柔韧性和耐腐蚀性的改性环氧底漆,所述色漆为提高了耐候性、刚性和柔韧性的改性聚氨酯色漆,所述清漆为聚氨酯清漆。本发明通过引入柔性链段改性环氧底漆,羟基开环接枝聚合法引入六元环状结构基团制备高性能面漆树脂,首次揭示柔性软醚键和联合酰胺基团对环氧树脂综合性能的影响规律以及六元环状结构基团、有机硅中间体对树脂聚合反应、树脂的成膜性能和涂料综合性能方面的影响规律和增强机理,诠释聚合工艺如二元醇种类和用量,反应温度等与漆膜综合性能的关系。
