Description
The present invention is a kind of spraying metal on nonmetallic materials surface and antique treatment method, belongs to the painted field of non-metal material surface, is used for handicraft surface spray metal and antique coloring.
China is the ancient civilized country, and art ware is of a great variety, and wherein outstanding will count ancient bronze ware of China and rock cave engraving.In order to carry forward the ancient culture of China, large quantities of sculptors, artist and engineers and technicians are engaged in the replication work of bronze ware, but because the cast copper cost is higher, and the casting technique difficulty is big, and this work of giving causes very big difficulty.
At present, non-metal material surface spraying copper, aluminium etc. are carried out paintedly abroad, general adopt metal dusts such as copper powders, aluminium powder and after pigment mixed mutually, spary was to non-metal material surface, as the method for being introduced in the JP52-19736 patent specification more.But this method is difficult to preserve the long period because material ageing problem, after general spary is painted through peeling off gradually once, two years.
The objective of the invention is to provide a kind of spraying metal on nonmetallic materials surface and antique treatment method, this method is with nonmetallic materials, carry out surface preparation earlier as gypsum, pottery, potter's clay, cement, fiberglass and timber, paper etc., metal such as copper, the aluminium etc. that will be in fusion or high-ductility state with spray gun spray on the above-mentioned non-metal material surface then, form needed metal coating.Nonmetallic materials to behind the spray copper adopt acidic chemical treatment fluid of the present invention that processing modelled after an antique is carried out on its surface again, make it become bronze colour.Generally need not handle for aluminium-plated metal coating, also can on aluminium-plated surface, carry out specific processing, to reach satisfied effect with polypropylene pigment.
The present invention realizes by the following method:
At first, as required the different matrix surface of spray metal is carried out preliminary treatment, i.e. surface preparation respectively.The purpose of surface preparation is the cleaning surfaces to be painted that makes matrix, coarse and be trimmed to suitable shape, to improve the bonding of coating and matrix.Its method is: will remove releasing agent earlier to the plastering surface, and then apply waterglass heat-resistant agent, i.e. Na from the teeth outwards
2SiO
4The aqueous solution; The blasting treatment than low stress is carried out on pottery, potter's clay, glass fiber reinforced plastics product surface, general 3-5 kilogram/every square millimeter; At the rarer waterglass of the surface brush last layer of timber and paper.
To the spraying metal on nonmetallic materials surface through above-mentioned surface preparation, its process is then:
To desire that metal spraying belongs to powder or wire is sent in the paint spray gun, BPT-1 type flame-spraying rifle or U.S. 12E wire spray gun as Beijing metallurgical equipment Research Institute, heat effect by oxy-acetylene flame stream makes metal dust or wire reach fusion or high-ductility state, and spray distance will be controlled at 3/5～4/5 of the length of flame.Spray distance is too far away, and the temperature of motlten metal powder and speed are too low, and the collision deformation amount is little, and it is not remarkable to inlay effect, and bond strength is not high; Spray distance is too near, removes and causes flame not enough to the heating-up temperature of metal dust, outside the deposition efficiency of powder reduces, and because flame is too near from working surface, can cause that also the surface is overheated, and it is not firm to bond.The relative workpiece movement speed of spray gun should rule of thumb remain in the suitable scope, flame stream is pressed the certain speed injection (for same spray gun to vaporific molten drop simultaneously, its jet velocity is certain), the metal of spraying is deposited to through on the previously prepared non-metal material surface, form needed metal coating.
Artistic article to behind the spray copper need carry out processing modelled after an antique, makes the non-metallic process product surface present bronze effect.
Grinder buffing is used earlier on the artistic article surface that at first will spray behind the copper, corase grind adopts the emery wheel of 30～60 order granularities, and usual speed is polished, and adopts the emery wheel of 60～120 order granularities to finish grind then, speed is more than 5000 rev/mins during correct grinding, at last with fabric disc polishing light.A kind of acidic chemical treatment fluid that spary the present invention develops on the artistic article surface that the nonmetallic materials of the light of polishing are made, it is corroded, then through daylight or ultraviolet ray irradiation is about can meet the requirements of bronze effect more than 5 minutes to product surface.
Acidic chemical treatment fluid of the present invention is made up of hydrochloric acid, copper sulphate, nickel ammonium sulfate, nickelous sulfate and water.
Each composition proportion of this acidic chemical treatment fluid is: add in 1 liter water
Hydrochloric acid 20-40 milliliter
Copper sulphate 150-250 gram
Nickel ammonium sulfate 130-150 gram
Nickelous sulfate 80-100 gram
With the product surface of this acidic chemical treatment fluid spary at economy-combat grinding and polishing light, because mostly sprayed on material is to contain in the copper a small amount of alloying element, surface color becomes aubergine very soon in acid liquid, under daylight or ultraviolet ray irradiation, treatment fluid continues to react with the top layer, and quicken its oxidizing process, color becomes black by aubergine, promptly disposes after waiting to be blackish green.Black excessively as color in processing procedure, available clear water flushing once.For making the treatment effect long-term stability, can in treatment fluid, add the stabilizing agent of trace.
In addition, also can be with iron oxide red, iron oxide black, copper sulphate adds in the polyvinyl chloride vainiss, and this solution brush behind the spray copper and on the product surface of polishing light, is wiped examination with solvent or diluent then gently, high bright spot is exposed, and low bright spot keeps, and also can reach bronze effect after brushing, the wiping like this.The part by weight of the above-mentioned three kinds of compositions that add in the varnish is: iron oxide red: iron oxide black: copper sulphate=(2～4): (1～3): the part by weight of (0.5～1) various compositions can suitably be adjusted according to the effect of being copied.For making the treatment effect long-term stability, can in solution, add the stabilizing agent of trace.
The inventive method is compared with plating, does not need at the surface preparation conductive layer, has also solved the problem that big part handicraft is difficult for plating simultaneously, compares with brush plating, and cost is low, efficient is high, and superiority is comparatively outstanding.And pottery, potter's clay, cement, gypsum, fiberglass and timber, paper can carry out above-mentioned spray treatment.Do old processing for the surface archaizing behind the spray copper and can make the non-metallic process goods present bronze effect, solved the antique treatment method of present domestic complexity, also opened up a new road simultaneously for Chinese large-sized city carving the first day of the lunar month.
Method of the present invention is compared with process in the past has following advantage:
(1) cast copper: cost very high (present one ton of clear copper price is about 25000 yuan), the casting technique difficulty is bigger, particularly large-scale sculpture and complex-shaped artistic article, it is bigger to mould difficulty.
(2) strike copper sheet: cost comes lower compared with cast copper, and weight ratio the former is light, be suitable for large-scale sculpture, as U.S.'s Statue of Liberty, copper sheet thickness is 3mm～5mm.
(3) spray copper is modelled after an antique: cost is very low, because of the thickness of spray copper is 0.25～0.30mm, and chemistry to make old cost low, realize easily, follow one's bent, be very suitable for large-scale outdoor sculpture, compared with the former two, cost is all low.
Embodiment:
Example one, cement spray copper is modelled after an antique
North gate, gymnasium, Beijing sculpture-hope
Beijing modern art sculpture company moulds, and is once prize-winning at the national sport sculpture.
This sculpture is high 3.5 meters, uses earlier cement casting, and wire brushing falls the scum silica frost and the dirt on surface then; Then at its surface spray copper, 0.2～0.4mm is thick for the spray copper thickness, again with abrasive machine and emery cloth polishing, get high bright spot, be stained with of the present invention by polyvinyl chloride vainiss adding iron oxide red, iron oxide black, copper sulphate with brush, it is transferred the solution of all forming, and its part by weight is: iron oxide red, iron oxide black, copper sulphate=3: 2: 0.5.This solution at sculpture surface brush last layer, with solvent or diluent wiping gently, is exposed high bright spot again, then obtain satisfied bronze effect.
Example two, plaster matrix spray copper is modelled after an antique
