Embodiment 1

[0049] (1) Formula of aircraft skin finishing paint

[0050]

[0051]

[0052] (2) Preparation steps

[0053] 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.

[0054] (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, rheology control aid, and catalyst reaches 20-30°C, and set aside;

[0055] (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 2-3 hours to obtain a uniform solution A;

[0056] (2.3) Slowly add fluorine-containing resin, SCA-modified polyester resin, and silicone-modified polyester resin to the uniform solution A in the pain...

Abstract

The invention relates to a formula and a preparation method of an aircraft skin finish coating. The formula consists of the following components in parts by weight: polyester resin with high hydroxyl content, 55-65 parts; fluororesin, 13-20 parts; SCA Modified polyester resin, 4‑8 parts; Silicone modified polyester resin, 6‑10 parts; Leveling aid, 0.05‑0.3 part; Rheology control additive, 0.1‑1 part; Catalyst, 0.05‑0.2 part ; Xylene, 3‑10 parts; Butyl acetate, 3‑5 parts. The aircraft skin coating of the present invention is matched with the crosslinking agent of HDI biuret and HDI trimer to have good weather resistance, corrosion resistance, oxidation resistance, high and low temperature resistance, excellent weather resistance, Impact and flexibility etc.

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....
