Problems solved by technology

The above two methods have some disadvantages, such as large-area painting takes a long time and costs a lot, the thickness of the interface between the new spray paint and the original car paint is not easy to control, and there is a more obvious color difference between the new and old paint layers
However, in the small-area repair method that uses a small brush to fill the paint and then polish it as much as possible, it is limited to the small area on the scratch. In the repair method, the thickness of the brush to fill the paint is not easy to be uniform. After the treatment, there are obvious bumps on the interface between the scratch and the original car paint surface. Boundary and chromatic aberration take a long time, so it is not suitable for promotion

Embodiment 1

[0034] Embodiment 1: a kind of repairing method of depth scratch, it comprises the following steps:

[0035] Step 1: Use alcohol to clean up the dirt in the scratches;

[0036] Step 2: Use 1500# sandpaper to polish the scratches. The sandpaper uses long strips of soft sandpaper, and the sanding area is 3 ± 0.1 cm;

[0037] Step 3: Use scissors to cut the cigarette paper into long strips of the same size as the scratches, and use the long strips of paper to fill the scratches with the paint prepared by paint and thinner at a weight ratio of 1:4, requiring fullness , fill 3 times, the thinner the better each time, and bake each time with an infrared oven; the temperature of the infrared oven is 75°C, and the time is 3 minutes;

[0038] Step 4: Use a fine brush to dip the prepared saliva and thinner according to the weight ratio of 1:5. Apply the saliva around the scratch, and then bake it with an infrared oven. The temperature of the infrared oven is 70 ° C, and the time is 5 ...

Abstract

The invention discloses a method for restoring deep scratches. The method comprises the steps that long strip paper is dipped with paint to fill the scratches firstly, and then the scratches are baked with a heating lamp; a thin writing brush is dipped with blended sealing water to smear the peripheries of the scratches, and then the scratches are baked with the heating lamp; then the scratches are filled with blended restoration liquid and paper strips as thick as the scratches and then baked with the heating lamp; the scratches are coated with the restoration liquid once through fingers; finally, ash scratching, grinding, polishing and waxing are carried out. The method has the advantages that the method is suitable for iron sheets, steel plates, aluminum alloy, plastic parts and other materials; the situation that the deep scratches and surrounding interfaces are different in thickness is avoided, the thickness is even, the connector of the treated scratches and an original car paint face has no obvious concave-convex boundaries or color difference, and the method is suitable for popularization; the boundary marks and color difference of the boundary of the restored scratches and the restoration surface and the original car paint face achieve the effect that distinguishing cannot be achieved with naked eyes, and the scratches are stable and cannot fall off; abrasive paper of different roughness degrees is adopted for grinding aiming at different conditions, the expected effect is achieved, and paint faces of other places cannot be damaged.

Description

technical field [0001] The invention relates to a method for repairing deep scratches, in particular to a method for repairing deep scratches on an automobile paint surface, and belongs to the technical field of automobile maintenance. Background technique [0002] Car paint scratches are traces of lines that appear on the surface of the paint. There are many reasons for it, for example: when the car is scrubbed, if there are hard particles in the cleaning agent, water or scrubbing tools (sponge, towel, etc.), it will scratch the paint surface; when polishing the paint surface, If the particle size of the selected grinding disc is large, the grinding force is heavy or the grinding is missed, scratches of varying degrees will be left on the surface of the paint. Also, when waxing, if you choose the wrong type of wax, and use sand wax on a new car by mistake, it will cause circles of scratches. Scratching the car with other cars during driving, scratching with roadside branc...
