Abstract
The invention discloses a hardware surface spraying technique which comprises the following work procedures of cleaning materials, removing dust, spraying base coat, spraying topcoat and curing through ultraviolet rays. Before the work procedure of spraying base coat, hardware is pre-roasted at low temperature, and a hardware work piece is roasted for 1 minute to 2 minutes at the temperature of 40-45 DEG C. After the hardware work piece is roasted, base coat is sprayed on the hardware work piece at the temperature of 45 DEG C.
Description
Technical field
The invention belongs to five metals processing technique field, be specifically related to a kind of five metals surface spray coating process.
Background technology
Hardware is the important industry link that industry manufactures, because most hardware is instrument used etc. in auxiliary products, half product and production process during industry manufactures, in long-term evolution, hardware industry has become the industry of a comparative maturity, the production technology of existing hardware is basically identical, after hardware stamping is shaping, through polished and cleaned, radium is carved, surface coloring sprays paint formation finished product.And in the face of the more and more specialized market demand and more and more fierce competition, mainly can capture market with client's or the surface treatment of five metals.The surface-treated object of handware is the attachment on five metals surface by coating or coating, obtain protecting five metals surface to be not easy to scratch, performance that anticorrosion, wear-resisting, resistance to hand perspiration etc. is good, obtained the various appearance colors of client's needs by surface coloring process simultaneously, wherein five metals steel disc, aluminium flake, zinc alloy surface spraying coloring process are exactly a kind of quick, surface treatment that cost is low, but the spraying effect that existing handware adopts always is high-brightness light surface effect; Namely on handware, spray transparent UV oil, then by ultraviolet curing, obtain the appearance that a kind of glossiness is high; And due to specular removal, really transparency is good, and some little defects on five metals surface are also difficult to cover in, so, higher defective products can be caused, reduce the first-pass yield of product, and, handware does high finish surface technique, has very high requirement to before material table, is unfavorable for reducing production cost.
Summary of the invention
Goal of the invention: for above-mentioned prior art Problems existing and deficiency, the object of this invention is to provide a kind of five metals surface spray coating process.
Technical scheme: the invention discloses a kind of five metals surface spray coating process, comprise following operation: cleaning material, dedusting, spray primary coat, spray plane painting, ultraviolet curing, before spray primary coat operation, low temperature prebake conditions is carried out to five metals, 1-2 minute is toasted under hardware workpiece being placed in the temperature conditions of 40-45 DEG C, after baking terminates, hardware workpiece carries out spray primary coat under temperature 45 C.
As further optimization of the present invention, the present invention is after described spray plane is coated with operation, and liquid coating on hardware workpiece surface spraying, the thickness that this liquid coating is formed on workpiece is 10-12um.
As further optimization of the present invention, liquid coating of the present invention is ultraviolet-curing paint.
As further optimization of the present invention, the present invention carries out low-temperature bake to hardware workpiece after liquid coating spray mo(u)lding: toast 10-15min under hardware workpiece being placed in the temperature conditions of 35 DEG C, naturally cools after low-temperature bake under dustless condition.
Beneficial effect: the present invention compared with prior art, have the following advantages: the present invention by adding prebake conditions operation in operation, make primary coat and face be coated with can be better more stable be attached to five metals surface, by low temperature prebake conditions, face is coated with and can not answers ambient temperature and form crackle on five metals surface, improve five metals surface coating quality, there is good economic benefit.
