As optionally, the first water-based short processes basecoat layer of background color enamelled coating is equal with the film thickness of second water-based short processes basecoat layer.
The utility model has positive effect: the coating structure of automobile ABS plastics exterior trimming parts of the present utility model eliminates floating coat on the one hand, and each coating is aqueous coating on the other hand, reduces painting cost, environmentally friendly, reaches the object of energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in above-mentioned accompanying drawing is as follows:
ABS plastic base material 1, first water-based short processes basecoat layer 2, second water-based short processes basecoat layer 3, clearcoat layer 4.
Detailed description of the invention
(embodiment 1)
See Fig. 1, the coating structure of the automobile ABS plastics exterior trimming parts of the present embodiment is made up of ABS plastic base material 1, background color enamelled coating and clearcoat layer 4; Background color enamelled coating comprises first water-based short processes basecoat layer 2 and second water-based short processes basecoat layer 3.Wherein first water-based short processes basecoat layer 2 covers and is fixed on the outer surface of ABS plastic base material 1, second water-based short processes basecoat layer 3 covers and is fixed on first water-based short processes basecoat layer 2, and clearcoat layer 4 covers and is fixed on second water-based short processes basecoat layer 3.
The film thickness of the first water-based short processes basecoat layer 2 of background color enamelled coating is 5 μm ~ 35 μm, in the present embodiment be 15 μm, flat smooth, it is the first water-based short processes basecoat of WBX-01A that first water-based short processes basecoat used derives from the commercial disignation that Changzhou Wujin Chenguang Metallic Paint Co., Ltd. produces, and comprises paint component and curing agent.
The film thickness of the second water-based short processes basecoat layer 3 of background color enamelled coating is 5 μm ~ 25 μm, in the present embodiment be 15 μm, flat smooth, it is the second water-based short processes basecoat of WBX-01B that second water-based short processes basecoat used derives from the commercial disignation that Changzhou Wujin Chenguang Metallic Paint Co., Ltd. produces.
The film thickness of clearcoat layer 4 is 25 μm ~ 60 μm, is 30 μm in the present embodiment, the coating varnish used acroleic acid polyurethane coating varnish for market is sold.
The preparation method of the coating structure of above-mentioned ABS plastic exterior trimming parts has following steps:
1. paint front surface process, namely the oil on removing surface and releasing agent complete the process of paint front surface.
2. first water-based short processes basecoat is sprayed; The paint component of first water-based short processes basecoat mixed with curing agent, be then sprayed on the surface of ABS plastic base material 1, levelling, after 2 ~ 3 minutes, obtains the first water-based short processes basecoat layer of 5 μm ~ 35 μm of thickness; First water-based short processes basecoat layer sprays second water-based short processes basecoat, and levelling, after 2 ~ 3 minutes, obtains the second water-based short processes basecoat layer of 5 μm ~ 25 μm of thickness; Predrainage at 80 DEG C, until the moisture taking off in first and second water-based short processes basecoat more than 85%.
During spraying first water-based short processes basecoat, every square meter solvent flashing 1 ~ 10g/m
