Problems solved by technology

The helicopter shell is made of aluminum alloy as the main material, combined with a part of high-strength polymer resin material and steel. During flight, dust, dirt in the air, and gas from helicopter fuel combustion may adhere to the surface of the aircraft. , These sundries are likely to contain corrosive substances, these dirt will adhere to the shell and make it polluted, if not cleaned for a long time, it will damage the structure of the aircraft, corrode the surface of the aircraft, and affect flight safety

Abstract

The invention discloses waterproof and anticorrosive paint for a helicopter. The waterproof and anticorrosive paint is prepared from components in parts by weight as follows: 36-45 parts of epoxy acrylic resin, 22-26 parts of isocyanate, 28-32 parts of n-butyl acetate, 16-25 parts of dibutyl benzoate, 21-27 parts of an organic solvent, 13-18 parts of polytetrafluoroethylene, 15-23 parts of polyethylene, 17-24 parts of neodymium fluoride, 13-22 parts of gadolinium fluoride, 15-19 parts of sodium oxide, 18-21 parts of triethanolamine,11-15 parts of titanium trioxide, 8-14 parts of a catalyst, 6-12 parts of filler and 22-34 parts of water. The paint has good waterproof performance, adhesive force and anti-corrosion property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof and anti-corrosion coating for helicopters and a preparation method thereof. Background technique [0002] Helicopters have many advantages that are difficult or impossible for other aircraft, and are widely used. Because helicopters can take off and land vertically without using large-scale airports, they are mainly used for sightseeing, fire rescue, first aid at sea, anti-smuggling and anti-drugs, fire fighting, business transportation, Various sectors of the national economy such as medical assistance, communication, and spraying pesticides to eliminate pests and explore resources. The helicopter shell is made of aluminum alloy as the main material, combined with a part of high-strength polymer resin material and steel. During flight, dust, dirt in the air, and gas from helicopter fuel combustion may adhere to the surface of the aircraft. , These sundries are li...
