Abstract

The invention relates to a nano aircraft coating and a preparation method and using method thereof. The coating is mainly applied to decoration of aircraft skin. According to the formula of the coating comprises, the component A comprises the the following raw materials in percentage by mass: 40 to 70 percent of high hydroxy acrylic polyol resin, 2 to 8 percent of nano SiO2 concentrated slurry, 10 to 30 percent of pigment filler, 1 to 5 percent of aid and 10 to 25 percent of organic solvent, the component B is a cross linker; and the mass ratio of the components A to the component B is 100: (25-50). The preparation method comprises the following steps of: 1) preparing the raw materials in the component A in a ratio, dispersing, and grinding to the fineness being less than 15 microns; and 2) mixing and curing the component A and the component B to prepare the nano aircraft coating. The nano aircraft coating is suitable for normal-temperature drying or low-temperature baking drying, and a film formed by the coating has the characteristics of high climate resistance, high self-cleaning property, high corrosion resistance, low friction, excellent wet and heat resistance, long service life and the like.

Description

technical field [0001] The invention relates to a nano coating, in particular to a nano aviation coating and its preparation method and application method. Background technique [0002] Aviation coatings are used for the coating and protection of aircraft skins. They are not only the appearance decoration materials of aircraft, but also important materials for aircraft structures that prolong the service life of aircraft and ensure safe flight. China's civil aviation department has predicted that in 2011, the domestic large aircraft C919 will usher in new orders, there are already 100 orders, and the total sales will reach 2,000 in the next 20 years; by 2012, China will need more than 1 of various general and military aviation aircraft. 10,000 aircraft, the various aviation coatings required for new manufacturing and maintenance will reach 5,000 tons, and there is a great demand for high-performance aviation coatings. Existing aerospace coatings, including nano-scale aviati...
