Abstract

The invention discloses a spray protection material usable for nondestructive color change and automobile body secondary creation. The spray protection material is made from raw materials including, by weight, 75-80 parts of TPU (thermoplastic polyurethane) resin, 5-10 parts of coloring pigment, 5-10 parts of solvents, 4-10 parts of curing agents, 3-10 parts of fillers, 3-5 parts of ultraviolet absorbents and 3-5 parts of antioxidants. A method for spraying the spray protection material on automobiles includes steps of spraying waterborne TPU materials on the surfaces of automobile paint underthe condition of the film thicknesses of 100-200 micrometers, and carrying out baking, drying and film forming by short-wave infrared rays for 1-1.5 hours; spraying waterborne TPU coating with pigment, carrying out uniform covering under the condition of the film thicknesses of 50-80 micrometers, and carrying out baking, drying and film forming by short-wave infrared rays for 30-50 minutes. The spray protection material has the advantages that the spray protection material is excellent in peeling property, waterborne coatings are free of optional damage on the original automobile paint, and accordingly nondestructive color change can be implemented; automobile body secondary creation can be carried out, and accordingly the spray protection material has great significance in maintaining the values of the automobiles; novel automobile life fashion can be led by nondestructive color change, and accordingly social harmony and splendidness and urban traffic cultural development can be assisted.

Description

technical field [0001] The invention relates to the technical field of automobile spraying, in particular to a spraying protection material which can be used for non-destructive color changing and secondary creation of car bodies. Background technique [0002] Existing car color changing mainly uses two categories of car spray paint and color changing sticking film. [0003] 1. Automobile painting: advantages, the paint is a permanent coating, and the original car paint needs to be destroyed before the construction operation can be carried out. The damage to the original car paint is relatively large, and the original car paint is permanently damaged and cannot be restored; the advantage is that the appearance is beautiful and beautiful, and the color variety is more Many, more mature industrial technology. [0004] 2. Color-changing film: Advantages, the film is generally made of PVC material, and the adhesive is pasted on the surface of the car paint, which can provide a ...
