Embodiment 1

[0048] (1) Formula of aircraft skin finishing paint

[0049]

[0050] (2) Preparation steps

[0051] According to the production volume, choose equipment and tools such as dispersing cylinder and dispersing machine, and choose the power of the machine. In principle, the higher the power, the easier it is to disperse the material, and make sure it is clean and trouble-free.

[0052] (2.1) Put the leveling aid and rheology control additive in a constant temperature room at 20-30°C, wait until the temperature of the leveling aid and rheology control agent reaches 20-30°C, and set aside;

[0053] (2.2) Slowly add the polyester resin with high hydroxyl content into xylene and butyl acetate under stirring, adjust the rotation speed to 100-300r / min, and stir for 2-3H to obtain a uniform solution A;

[0054] (2.3) Slowly add fluorine-containing resin, SCA-modified polyester resin, and silicone-modified polyester resin to the uniform solution A in the paint mixing tank in sequence,...

Abstract

The invention relates to a formula of aircraft-skin finish coating and a preparation method thereof. The formula comprises the following components in parts by weight: 55-65 parts of polyester resin with high hydroxy content, 13-20 parts of fluororesin, 4-8 parts of SCA modified polyester resin, 6-10 parts of organic silicon modified polyester resin, 0.05-0.3 part of leveling additive, 0.1-1 part of rheological control additive, 0.05-0.2 part of catalyst, 3-10 parts of dimethylbenzene and 3-5 parts of butyl acetate. The formula has the advantages that the aircraft-skin coating is matched with HDI biuret and HDI tripolymer cross-linking agent, so that the aircraft-skin finish coating is good in weather resistance, corrosion resistance, oxidation resistance and high-low temperature resistance, and is excellent in weather resistance, impact resistance and flexibility and the like.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an aircraft skin finish paint and a preparation method thereof. Background technique [0002] The aviation industry is one of the key points of the industry revitalization plan in the rapid implementation of the economic stimulus plan in the face of the world economic crisis. Now, my country is one of the fastest-growing regions in the world's civil aviation market, and my country will become the third center of Airbus in the world, which is an important part of the national large aircraft development strategy. With the development of the global aviation industry, aerospace coatings have also been greatly developed. Since coatings play an important role in protecting aircraft, the technical requirements for aerospace coatings are also getting higher and higher. [0003] China's large aircraft project was officially established in 2007, and China Commercial Aircraft Co....
