Abstract

The invention relates to a preparation method of surface patterns of metal artware, in particular to a preparation method of color patterns of a relief, belonging to the field of manufacturing technology of artware. The method comprises the following steps: (1) oil removing is carried out to surface of base material, and then washing, rust removal, washing, phosphating, washing, drying, sensitive development corrosion-resisting layer coating, washing and drying are carried out; (2) a relief pattern is manufactured on a light-sensitive film; (3) the light-sensitive film is used for exposure on the base material in a dark room, and then development and drying are carried out; (4) the base material is etched by corrosive liquid to lead a corrosion-resisting membrane layer to carry out light sensitivity and development; (5) coloring, baking varnish and polishing are carried out to the pattern. By adopting the method, pattern carving is exquisite, and control is easy, thereby being suitable for mass production of artware.

Description

Metal artware relief color-painting method

Technical field

The present invention relates to a kind of preparation method of metal handicrafts picture on surface, the preparation method of embossment multicolour pattern particularly belongs to the manufacture technology field of handicraft.

Technical background

Traditional metal handicrafts surface relief pattern has two kinds of mould forming method and hand engraving methods.

Mould forming method is, the operator carves good needed mould with icking tool on inkstone watt stone, behind metal moltens such as tin, casts in institute and carve in the good mould, and casting forms after cooling off.Though can produce in batches, pattern quality has much relations with engraving artist's level and state, when running into less font and pattern, just is difficult to reach effect preferably, and in addition, traditional tinwork netrual colour is decorated.

The hand engraving method is that the operator directly carves out font and pattern with scorper on metal, and this method production efficiency is very low, and technical requirement is very high, and can not guarantee that the pattern of every metal handicrafts is in full accord.

Computer-controlled engraving machine has appearred in the development of Along with computer technology in recent years, though its machining precision and efficient have been higher than hand engraving, and the only suitable flat board engraving less to size, and working (machining) efficiency is still lower, and the expense of equipment set is also higher.

Summary of the invention

The purpose of this invention is to provide a kind of metal artware relief color-painting method, its easy master, the pattern engraving is exquisite, and efficient is high, but painted decoration suits the handicraft of various sizes and shape is produced in enormous quantities.

Realize that the technical scheme that order of the present invention adopts is: to the substrate surface oil removal treatment, washing eliminates rust (1), washing, and phosphatization, washing, oven dry is coated with sensitization development resist layer, washing, drying; (2) embossing pattern is produced on the sensitive film; (3) make public on base material with sensitive film in the darkroom, develop drying; (4), remove the sensitization rete against corrosion that develops with corrosive liquid etching base material; (5) to pattern colouring, baking vanish, polishing.

Concrete technical scheme of the present invention also comprises:

What the substrate surface rust cleaning was adopted in the step (1) is the Tianna solution solution of mass concentration 20～30%; Phosphatization dried after being washed temperature is 90～110 ℃; Sensitization development resist layer adopts the photosensitive resist printing ink of anti-the plating, and the coating thickness 0.6～1.5mm of ink lay, baking temperature are 70～90 ℃; Time shutter is 9～11 seconds in the step (3), concentration 0.8～1.2wt% solution of developer solution, and development temperature is 25～32 ℃, the back of developing was 90～110 ℃ of dryings 5～10 minutes; Corrosive liquid adopts hydrochloric acid or the sulfuric acid solution of concentration 15～40wt% in the step (4), and corrosion temperature is 10～50 ℃, removes the Tianna solution solution that the photosensitive resist ink lay of anti-the plating adopts concentration 20～30%.

What colouring was adopted to pattern is baking varnish coating, and the baking vanish temperature is controlled at 45～120 ℃.

The invention has the beneficial effects as follows:

Owing to adopted the sensitization technology to combine with chemical etch technique; Can simplify the skill of making the embossment multicolour pattern greatly; Can high-level efficiency, produce the toreutics article in enormous quantities; Processing a same product this method is 1/60～1/80 of the artificial engraving method time spent, is 1/6～1/10 of the computer sculpture method time spent; The sensitization The Application of Technology can produce on the metal handicrafts surface than the meticulousr pattern of artificial engraving, and the chemical corrosion liquid etching has then solved the special demands to the high skill of workman, and anaglyph is more true to nature; The colored drawing baking vanish has solved traditional metal technology bossage can't go up a color difficult problem.

Embodiment

Embodiment:

1, design needed pattern with computing machine, design producing on sensitive film.

2, be processed into into needed shape with metals such as tin, copper, use the alkali lye oil removing, in 20～30% Tianna solution, add a small amount of corrosion inhibiter rust cleaning again; Washing is clean, carries out phosphatization and handles, the bonderite of washing metal surface; 90～110 ℃ of oven dry down; One deck 800 type photosensitive-ink of even coating thickness 0.6～1.5mm are washed 70～90 ℃ of dryings then.

3, in the darkroom, utilize sensitive film on metallic objects such as tin, copper, to make public, use 1% aqueous sodium carbonate to be developer solution, 25～30 ℃ of temperature are developed, and on metal, show required pattern, and the back of developing was 90～110 ℃ of dryings 5～10 minutes.

4, in the control of 10～50 ℃ temperature down, use concentration to erode away male and fomale(M&F) as the HCl corrosive liquid of 33wt%, the formation space pattern is again with the rete against corrosion that develops of residual sensitization on 20% the Tianna solution solution removal metal.

5, paint with baking varnish coating according to pattern, carry out baking vanish at 80～100 ℃ then, polishing obtains finished product at last.
