NOVELTY - The method for preparing anticorrosive polyurethane pressure-sensitive adhesive for aviation, involves mixing hydroxy-terminated polybutadiene with modified diphenylmethane diisocyanate, adding organotin drying agent, heating and stirring under protection of nitrogen to obtain first intermediate product, adding anticorrosive system to first intermediate product, and stirring evenly to obtain second intermediate product, heating and stirring second intermediate product, amino-terminated polybutadiene and drying agent, and adding dye to obtain third intermediate product, adding reinforcing component to third intermediate product to prepare anticorrosive polyurethane pressure-sensitive adhesive for aviation, where the modified diphenylmethane diisocyanate is carbodiimide modified diphenylmethane diisocyanate. USE - Method for preparing anticorrosive polyurethane pressure-sensitive adhesive for aviation (claimed). ADVANTAGE - The method enables preparing anticorrosive polyurethane pressure-sensitive adhesive ensuring excellent anticorrosive performance and stable properties, and adapts to harsh environment of aviation applications.
