| The work aims to effectively block the oil steam, so as to reduce the risk of oil leakage and improve the safety and comfort of aircraft. The design method of polyurethane modification was adopted, and then the coating was synthesized and prepared. Next, the coating properties were tested and evaluated by means of grid method, mechanical stretching method, solution soaking method, neutral salt spray, wet heat and other methods. The following formula was selected, including polycaprolactone polyol with molecular weight of 2000 and content of 13.1%, amine chain extender E-300 with content of 8% and isocyanate HMDI with content of 25.2% and thus the coating with the best comprehensive properties was obtained. The fracture strength and elongation at break of the prepared coating reached 26.6 MPa, and the elongation at break reached 580.0%. The coating had no failures such as foaming and peeling after being subject to solution soaking (500 h), neutral salt spray (500 h) and moisture and heat (500 h). The design scheme of polyurethane modified vapor isolation coating material/coating is reasonable, the synthesis process is easy to realize and the comprehensive properties of the coating material system are excellent, so it can be used as the protective coating in the fuel tank of aircraft under complex and harsh conditions. |
