Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a surface decorative film for the exterior of the UAV and its preparation method and application, so as to solve the traditional UAV exterior painting proposed in the above-mentioned background technology. The decorative film on the surface of the part is usually wrapped with a simple waterproof film. When the UAV is in high temperature weather or thunderstorm weather, it cannot effectively protect the high temperature and thunderstorm, which will cause the UAV to be damaged and cause loss.

Abstract

The invention discloses an unmanned aerial vehicle exterior paint-sprayed part surface decoration film and a preparation method and application thereof. The preparation method comprises the following steps that 1, materials and experimental instruments needed by an experiment are prepared; 2, polyacrylonitrile, N, N-dimethylacetamide, polyvinylpyrrolidone, polyimide YJ-16 and polymethyl methacrylate are heated to 70 DEG C in a dissolving kettle according to the proportion and dissolved for 4-6 h, then standing defoaming is conducted for 24 h, dry-wet spinning is conducted at the room temperature, and the carbon fiber base film is obtained. By using the carbon fiber, the carbon fiber film has the advantages of being chemically stable and used at high temperature, and the performance of the film can be controlled according to the carbonization degree of the hollow fibers, is between that of an inorganic film and that of an organic film, and can meet the requirements of harsh conditions, the film can be used in the fields of high-temperature gas separation, organic solvent separation and the like, and avoids the problems that the film cannot effectively protect from high temperature, thunderstorm and the like and then the unmanned aerial vehicle is damaged and loss is caused.

Description

technical field [0001] The invention belongs to the technical field of decorative film for drones, and in particular relates to a decorative film for the surface of a painted part of an exterior decoration of a drone, a preparation method and application thereof. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photog...
