Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The invention relates to a method for repairing a hydrogen energy automobile part by using UV type resin, which specifically comprises the following steps of aiming at the scratch depth H being less than or equal to 1mm and the width W being less than or equal to 2 mm: firstly, coating or spraying UV resin on the changed area, covering a transparent film, then scraping the resin smoothly along the damaged area, removing the redundant UV resin, irradiating by using ultraviolet rays, and removing the surface film after curing (as shown in figure 1); aiming at the scratch depth H being more than or equal to 1mm and the width W being more than or equal to 2mm, the repairing method comprises the following specific steps: firstly, polishing a damaged area, laying fibers on the damaged area, coating UV resin with a certain thickness, irradiating by using ultraviolet rays, then coating UV resin with a certain thickness, irradiating by using the ultraviolet rays, repeating the steps until the repair is finished, and finally, polishing the surface to be neat and smooth (as shown in figure 2).
The method for repairing the hydrogen energy automobile part by using the UV resin has the following beneficial effects:
1. the high-efficiency rapid repair of parts is facilitated, and the UV resin can be cured in a very short time under the irradiation of ultraviolet light.
2. The operation is simple, the use is convenient, and the UV resin adopts a single-component system without mixing.
3. The method does not need to use a solvent, does not generate volatile gas, does not pollute the environment, does not harm human bodies, and is energy-saving and environment-friendly.
4. Excellent performance, wear resistance, solvent resistance, impact resistance, high strength and ultraviolet resistance.
5. The composite material and the metal material can be repaired.
The type of fiber is various and is not limited herein, for example: the fibers may include one or more of carbon fibers, glass fibers, basalt fibers, aramid fibers, and natural fibers.
Aiming at the scratch depth H being more than or equal to 1mm and the width W being more than or equal to 2mm, the thickness of the uv resin paved each time is not more than 3 mm. In the ultraviolet transmission range, the complete curing of the UV resin is ensured, and the phenomenon that the ultraviolet energy is insufficient and the curing is incomplete due to the over-thick layer is avoided. The curing time is as fast as possible within 3s by ultraviolet irradiation.
The above is not relevant and is applicable to the prior art.
