Problems solved by technology

The 3C coating film consists of three layers of primer, color paint and varnish in sequence. The primer is used to improve the adhesion of the topcoat, ensure the uniform absorption of the topcoat, and make the paint system play the best effect. During construction, we found that the use of In the process of painting with 3C1B process, the hiding power of the primer is unstable after painting, and the effect is not obvious after corresponding adjustments, and there are phenomena such as difficult process management, low cleanliness, and unstable quality during the painting process , which continues to plague construction operations

Embodiment 1

[0029] A C51E spoiler coating process, comprising the following steps:

[0030] The first step: pre-treatment, the operating environment temperature is 25°C, and the humidity is 30%. First, use shell water to degrease the C51E spoiler, then use a rag to wipe the C51E spoiler with absolute ethanol, and finally Blow away the accumulated dust still adhering to the spoiler with a static-removing gun, thereby completing the operation of removing oil and dust on the surface of the spoiler;

[0031] Step 2: Spray colored paint. The operating environment temperature is 26°C and the humidity is 40%. Mix 120g of colored paint main agent, 12g of colored paint curing aid and 105g of colored paint thinning aid and spray it with Iwata W101 pneumatic spray gun. The injection pressure of Iwata W101 pneumatic spray gun is 0.3Mpa, and the spray width is 120mm;

[0032] The third step: spraying varnish, the operating environment temperature is 26 ℃, humidity is 40%, mix 120g varnish main agent,...

Embodiment 2

[0038] A C51E spoiler coating process, comprising the following steps:

[0039] The first step: pre-treatment, the operating environment temperature is 25°C, and the humidity is 45%. First, use the shell water to degrease the C51E spoiler, and then use a rag to wipe the C51E spoiler with absolute ethanol, and finally Blow away the accumulated dust still adhering to the spoiler with a static-removing gun, thereby completing the operation of removing oil and dust on the surface of the spoiler;

[0040] The second step: spray paint, the operating environment temperature is 27 ℃, the humidity is 50%, mix 150g of paint main agent, 15g of paint curing aid and 120g of paint dilution aid, and then spray it with Iwata W101 pneumatic spray gun. The injection pressure of Iwata W101 pneumatic spray gun is 0.4Mpa, and the spray width is 130mm;

[0041] The third step: spraying varnish, the operating environment temperature is 27 ℃, humidity is 51%, mix 125g of varnish main agent, 56.3g of...

Embodiment 3

[0047] A C51E spoiler coating process, comprising the following steps:

[0048] The first step: pre-treatment, the operating environment temperature is 25°C, and the humidity is 55%. First, use shell wiping water to degrease the C51E spoiler, then wipe the C51E spoiler with a rag dipped in absolute ethanol, and finally Blow away the accumulated dust still adhering to the spoiler with a static-removing gun, thereby completing the operation of removing oil and dust on the surface of the spoiler;

[0049] Step 2: Spray colored paint. The operating environment temperature is 29°C and the humidity is 40%. Mix 165g of colored paint main agent, 30g of colored paint curing aid and 135g of colored paint thinning aid and spray it with Iwata W101 pneumatic spray gun. The injection pressure of Iwata W101 pneumatic spray gun is 0.3Mpa, and the spray width is 135mm;

[0050] The third step: spraying varnish, the operating environment temperature is 29 ℃, humidity is 40%, mix 130g varnish m...

Abstract

The invention provides a spoiler coating technology. The technology comprises following steps of pretreatment, color paint spraying, mixing a color paint main agent, a color paint curing assistant and a color paint dilution assistant, spraying a mixture through a spraying gun, varnish spraying, mixing a varnish main agent, a varnish curing assistant and a varnish dilution assistant, spraying a mixture through a spraying gun, leveling, drying, drying in a hot air drying furnace, offline operation and finished product checking. According to the spoiler coating technology, on the basis of original 3C1B, the primer working procedure is reduced, the work efficiency is correspondingly improved by 30%, the total use amount of the coating is reduced by 33%, and the yield of a coating working procedure is improved by 17%.

Description

technical field [0001] The invention belongs to the technical field of automobile surface treatment, in particular to a spoiler coating process. Background technique [0002] The original spoiler was painted using the 3C1B process, that is, the process of spraying the primer, metallic paint and varnish in a "wet-on-wet" manner, and drying them all at once. The 3C coating film consists of three layers of primer, color paint and varnish in sequence. The primer is used to improve the adhesion of the topcoat, ensure the uniform absorption of the topcoat, and make the paint system play the best effect. During construction, we found that the use of In the process of painting with 3C1B process, the hiding power of the primer is unstable after painting, and the effect is not obvious after corresponding adjustments, and there are phenomena such as difficult process management, low cleanliness, and unstable quality during the painting process , which continues to plague construction ...
