Waterproof anti-corrosion flame retardant coating for airplane and preparation method thereof

Abstract

The invention relates to a waterproof anti-corrosion flame retardant coating for an airplane and a preparation method thereof. The coating is prepared from tung oil, ethylene-vinyl acetatecopolymer emulsion, decabromodiphenyl oxide and magnesium hydroxide according to the weight ratio of 60-80:10-30:5-10:5-10. The waterproof anti-corrosion flame retardant coating for the airplane uses the tung oilhaving the characteristics of waterproof property, anticorrosion, high temperature resistance, and the like as the main material, matches the decabromodiphenyl oxide and magnesium hydroxide with theflame retardant function and uses the ethylene-vinyl acetatecopolymer emulsion as the adhesive. Therefore, when applied on the surface of a structural component of the airplane to form an adhesive film with the waterproof, anti-corrosion and flame retardant effects, the waterproof anti-corrosion flame retardant coating can prevent material lamination or even damage caused when the external moisture and corrosive substances enter the inside of the structural component and has flame retardant effect, thereby prolonging the service life of the structural component and ensuring good safety.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a waterproof, anti-corrosion and flame-retardant coating for aircraft and a preparation method thereof. Background technique [0002] At present, the materials used in aircraft structural components mainly include sheet metal and composite materials. Because composite materials can effectively improve the performance of aircraft, they have been widely used in the aviation industry and have become one of the indispensable materials in the field of aviation manufacturing. However, most of these composite materials are manufactured by lamination and bonding process. In the above process, the inside of the material and the bonding surface often have foreign matter inclusions, debonding, delamination, affinity detachment due to some reasons. Defects such as sticking, weak bonding and fiber breakage, especially debonding and delamination are the most common phenomena, whic...

[0003] In addition, the structural components in the aircraft galley are often in close contact with water, coffee and carbonated beverages, while the structural components in the bathroom are often in contact with water, urine, acid-base deodorants, detergents and other substances. This will cause the joints between these structural components to be corroded by the above-mentioned substances, and the material itself will also be corroded. The most severely corroded parts are the surface joint layer and internal honeycomb of the kitchen; the bathroom floor, the internal honeycomb of the floor, and the fixed door As a result, the service life of structural components is greatly shortened
