A kind of car paint repair paint and its repair process

Abstract

The invention discloses a car paint repair paint and a repair process thereof. The car paint repair paint includes a filling component and a primer component, and the filling component is arranged at the bottom of the scratch to scratch the paint surface of the car. Filling, the bottoming component is set on the surface of the filling component to further fill the car paint surface; the present invention sets the repair paint as the filling component and the bottoming component, through the filling component with high solid content and good fluidity The position to be repaired is automatically filled, avoiding the step of using atomic ash for grinding, and at the same time, the bonding force between the filling component and the body sheet metal is greatly improved by pretreatment of the body sheet metal. The component further fills the position of the car body to be repaired, and the base component dissolves the original car paint surface and the filling component in contact with the base component, which reduces the color difference of the interface, makes the color transition smoother, and improves The binding force between the filling component and the bottom component is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance and repair, and in particular relates to an automobile paint repair paint and a repair process thereof. Background technique [0002] In order to protect the car body and make the car body have a good luster for a long time without being corroded, the surface of the car body will be coated with car paint, which not only has a good protective effect, but also can improve the exterior light of the car. The car paint mainly includes primer Compared with the topcoat, the primer is a paint with more filler content, and the topcoat is a paint with a low filler content. The primer is mainly used to fill the uneven sheet metal body to form a smooth surface, and then apply it to the primer Coat the topcoat to form a weather-resistant and acid-base protective layer with high hardness. In the prior art, the body surface paint is mainly processed and prepared with resin, additives and solvents ...

Problems solved by technology

[0002] In order to protect the car body and make the car body have a good luster for a long time without being corroded, the surface of the car body will be coated with car paint, which not only has a good protective effect, but also can improve the exterior light of the car. The car paint mainly includes primer Compared with the topcoat, the primer is a paint with more filler content, and the topcoat is a paint with a low filler content. The primer is mainly used to fill the uneven sheet metal body to form a smooth surface, and then apply it to the primer Coat the topcoat to form a weather-resistant and acid-base protective layer with high hardness. In the prior art, the body surface paint is mainly processed and prepared with resin, additives and solvents as the main materials. When encountering a certain intensity of scratches Sometimes, the paint layer on the surface of the car will be scraped off, leaving white marks, and even the metal layer of the car body will be exposed seriously. Contaminated with dust, it needs to be cleaned in time. During the cleaning process, due to the hard particles attached to the paint surface of the car and the defects of the cleaning tool itself, it is easy to leave many tiny scratches on the car body. Bad appearance

[0003] In the prior art, in order to make up and cover the scratches, it is necessary to fill the scratches. When filling, the scratches are first filled with putty, and then the surface of the putty is coated with a topcoat to achieve repairing. When using atomic putty to fill scratches, it needs to be continuously polished. It is difficult to clean up after polishing, and it is easy to form a solidified atomic putty film around the scratches, resulting in a large area of ​​color difference. At the same time, atomic putty is composed of a large amount of filler and a small amount of curing agent. , the drying time is long during curing, the drying effect is poor, and deformation and local looseness are prone to occur. In order to solve this problem, the present invention provides the following technical solutions
