Embodiment 1

[0040] The invention discloses a metal surface treatment method, the specific steps are as follows:

[0041] (1) Degreasing: Use a white cotton cloth to dip in the oil cleaning agent to wipe the oil on the surface of the metal parts;

[0042] (2) Sandblasting: Use paper tape to seal and isolate the non-adhesive surface of the metal parts, and then perform sandblasting, and use the impact of high-speed sand to clean and roughen the surface of the metal parts, so as to promote the roughening of the adhesive surface of the metal parts , increase the surface roughness of metal parts;

[0043] (3) Wipe and clean: Use a clean white cotton cloth dipped in oil cleaning agent to wipe the surface of the metal parts until the surface of the metal parts is completely clean. After cleaning, place it at room temperature for 1.5 hours;

[0044] (4) Primer treatment: Take out the primer from the -18°C cold storage, place it at room temperature for 7 hours before use, and then evenly apply a ...

Abstract

The invention discloses a treatment method of a metal surface. The treatment method of the metal surface comprises the following specific steps that a white cotton cloth is adopted to be used for dipping an oil stain cleaning agent to wipe oil stains on the surface of a metal part; a non-adhesive junction face of the metal part is sealed and isolated by adopting a paper adhesive tape, then sand blasting is carried out, the surface of the metal part is cleared and coarsened by utilizing the impact action of a high drift sand, so that the coarsening of the junction face of the metal part is facilitated, and the surface roughness of the metal part is increased; the oil stain cleaning agent is used for wiping the surface of the metal part until the surface of the metal part is completely clean, and the metal part is left to stand for 1.5 hours under the condition of room temperature after clearing; a bottom glue is taken out of a cold storage at a temperature of minus 18 DEG C, then the bottom glue evenly coats the surface of the metal part, after the surface is coated with the bottom glue and the glue liquid is solidified, then the bottom glue can be put in a furnace for solidification; the constant-temperature solidification is performed for 1-2 hours; a layer of glue film is pasted to a part glue joint area; and the constant-temperature solidification is performed for 1-3 hours. The treatment method of the metal surface has the advantages that the bonding strength of a composite material and the metal part is enhanced, the service life is prolonged.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a metal surface treatment method. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote control with a parachute or a block. Can ...
