Embodiment Construction
[0012] The present invention will be further described below in conjunction with specific embodiments.
[0013] A method for repairing damaged surface of engine exterior paint, is characterized in that, comprises the following steps:
[0014] a. Grind the surface of the barge, and use fine mist water to clean the polished part during the grinding process, and then use deionized water and organic solvents to clean the surface of the engine shell to make the surface of the engine shell smooth, clean and free Dust, no rust, no grease;
[0015] b. The treated barge is treated to increase the surface roughness to enhance the surface adsorption capacity of the car door;
[0016] c. Pre-coat the primer on the spraying part of the engine shell. The primer is a silicone rubber pre-coating primer. When spraying, the shell is rotated along the axial direction and sprayed at the same time, so that the spraying track is a circle;
[0017] d. Put the engine casing sprayed with pre-coated ...

Abstract
The invention discloses a repairing method for an external lacquer damaged surface of an engine. The repairing method comprises the following steps that (1) the surface of a roll line is polished, in the polishing process, fine mist water flow is used for cleaning of the polishing position, and then deionized water and an organic solvent are used to conduct cleaning treatment on the surface of an engine shell, so that the surface of the engine shell is smooth, clean and free of dust, rust and grease; (2) the treated roll line is subjected to surface roughness increasing treatment to improve the adsorption capacity of the surface of a car door; (3) priming paint precoating is conducted on a spraying part of the engine shell, priming paint adopts silicone rubber precoating priming paint, and when spraying is conducted, the shell rotates along the axial direction and is sprayed simultaneously, so that a spraying track is a circular ring; and (4) the engine shell spayed with the precoating priming paint is placed at indoor space, solidifying is conducted for 12 h at the indoor temperature, and then a heat-insulating coating is sprayed. By adopting the repairing method, the stability of the coating can be improved effectively.
Description
technical field [0001] The invention relates to the field of engine manufacturing, in particular to a method for repairing damaged surfaces of engine exterior paint. Background technique [0002] At present, whether it is used in aerospace, or vehicles such as vehicles, the engine must withstand high temperature and heat. In order to improve the heat resistance of the engine, the outer surface of the engine is sprayed with heat-insulating paint and anti-static primer to form a protective coating. However, most of the coatings produced by existing processes have poor quality stability and low coating efficiency. Contents of the invention [0003] The present invention aims to provide a method for repairing the damaged surface of the outer paint of the engine to solve the above problems. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A method for repairing damaged surface of engine exterior paint, is characterize...
