Abstract
The utility model discloses a colorful coating structure of an acrylonitrile butadiene styrene (ABS) plastic exterior trimming part for an automobile, which takes ABS plastic as base material. The colorful coating structure comprises a primer layer and a finish paint layer inside-out from thee surface of the ABS plastic as the base material, wherein the finish paint layer can be a single-layer finish paint layer or a double-layer finish paint layer; the thickness of the paint film of the primer is 25-30 um; the double-layer finish paint layer comprises a primary colored paint layer and a varnish layer coated on the primary colored paint layer, wherein the thickness of the paint film of the primary colored paint layer is 15-20 um, the thickness of the paint film of the varnish layer is 35-40 um, and the thickness of the paint film of the single-layer finish paint film is 35-40 um. The colorful coating structure simultaneously satisfies the requirements of low price, light weight, easy processing, high strength and attractive appearance of the exterior trimming part for the automobile. As the ABS plastic serves as the base material, the colorful coating structure has no phosphating salt conversion coating or electrophoretic paint layer compared with the coating for the traditional steel plate coating, and the coating cost is also lowered.
Description
Technical field
The utility model relates to automobile-used exterior trimming parts, particularly a kind of coloured coating structure of ABS plastic exterior trimming parts.
Background technology
At present, the automobile-used exterior trimming parts that comprises bumper, radiator grille, deflector, radiator grid, dashboard and door trim plate etc. progressively is substituted by working of plastics by metalwork.The material of auto plastics comprises polypropylene, polyurethane, polyvinyl chloride, same with thermosetting compound material, ABS, polyamide, Merlon, polyformaldehyde, polyphenylene oxide, polymethyl methacrylate and polyethylene or the like.ABS wherein is an acrylonitrile (Acrylonitrile), 1, the graft copolymer of 3-butadiene (Butadiene), three kinds of monomers of styrene (Styrene), be a kind of intensity height, good toughness, be easy to thermoplastics type's macromolecular material of machine-shaping, and its hear resistance, lower temperature resistance, chemical proofing and excellent electrical properties, also have characteristics such as easy processing, product size is stable, lustrous surface is good, easily application, painted can also be carried out surperficial metalling, plating, welding, hot pressing and secondary operations such as bonding.The automobile-used exterior trimming parts of making of ABS resin that comprises automobile exterior spare is light weight, good economy performance not only, and can satisfy the complicated shape of exterior trimming parts and curved surface simultaneously and require requirement with high impact strength.Adopt the material of plastics, not only can reduce cost, design more fashion and the more profile of aerodynamic, simultaneously by to mould the deadweight that Dai Gang has alleviated automobile greatly as automobile-used exterior trimming parts.But because the color of this auto plastics exterior trimming parts just once forms when injection moulding, if will change, both have certain aberration.In addition, because of the restriction of color masterbatch kind, often can not satisfy the different demands of consumers in general simultaneously during injection moulding to various numerous and diverse colors.Therefore; often adopt with the similar method of steel exterior trimming parts in the corresponding coating of auto plastics exterior trimming parts external coating; make the auto plastics exterior trimming parts demonstrate needed color on the one hand, formed on the other hand coating plays the effect of protection auto plastics exterior trimming parts.Usually the face coat of auto plastics exterior trimming parts is three layers of coating, from inside to outside is followed successively by prime coat, the middle coat of paint and top coat layer.Top coat layer has two kinds of forms, a kind of form is the top coat layer (as colored polyurethane enamelled coating) of individual layer, another kind of form is double-deck top coat layer, by the primary colours enamelled coating that is positioned at internal layer (also claiming the background color enamelled coating) be positioned at outer field Lacquer finish enamelled coating (also claiming clearcoat layer or layer of varnish) and form.This coating system is complex structure not only, and the process-cycle is longer.
Summary of the invention
Technical problem to be solved in the utility model provides the coloured coating structure of short automobile-used ABS plastic exterior trimming parts of a kind of simple in structure, process-cycle.
The technical scheme that realizes the utility model purpose is a kind of coloured coating structure of automobile-used ABS plastic exterior trimming parts, comprises the ABS plastic matrix, also comprises prime coat and top coat layer; The prime coat bonding fixedly covers on the outer surface of ABS plastic matrix, and the top coat layer bonding fixedly covers on the prime coat.
The film thickness of above-mentioned prime coat is 25 μ m～30 μ m.
Above-mentioned top coat layer is double-deck top coat layer, comprise primary colours enamelled coating and layer of varnish, primary colours enamelled coating bonding fixedly covers on the prime coat, and the layer of varnish bonding fixedly covers on the primary colours enamelled coating, the film thickness of primary colours enamelled coating is 15 μ m～20 μ m, and the film thickness of layer of varnish is 35 μ m～40 μ m; The primary colours enamelled coating is coated with pearly-lustre primary colours enamelled coating for matel coated flash of light primary colours enamelled coating in exempting from or in exempting from.
Above-mentioned top coat layer is the individual layer top coat layer; The film thickness of individual layer top coat layer is 35 μ m～40 μ m; Top coat layer is for being coated with the individual layer top coat layer in exempting from.
The utlity model has positive effect: the coloured coating structure of (1) ABS plastic of the present utility model satisfies automobile-used exterior trimming parts economy, light weight, easily processing, high strength and requirement attractive in appearance simultaneously.(2) owing to adopt ABS plastic as base material, the coating when comparing the conventional steel plates application is saved phosphatization salt conversion film and electrophoretic paint layer, also reduces cost aspect application.(3) coating structure of the present utility model has been removed floating coat from, has further reduced painting cost, and has reached the purpose of energy-saving and emission-reduction.
