Description
Technical field
The present invention relates to a kind of coloring liquid and application of spot copper, belong to surface treatment and the ornameutal handiwork field of metallic substance.
Background technology
Spot copper is as the peculiar brass in Yunnan, and it adopts high-grade copper-based alloy material, and through shape-designing, casting, Seiko is polished and the subsequent technique process making of other complexity obtains, and obtains the speckle being mingled with shape, varying in color.Spot copper has been valued for spot, speckle dimly visible in Copper base material make bornite handicraft have red in the marvellous color of thoroughly spot, golden yellow friendship brightness, be the exclusive a kind of special warfare of China.The surface of its maroon, the speckle presented, has simple and honest, simple and unsophisticated, elegant impression, can be rated as the hat of smithcraft.Its surface shows the staggered color of various irregular magnificent decorative pattern and golden red, is the distinctive folk traditional craft product in Yunnan Province, is also the traditional handicraft product that China shows unique characteristics, has very high artistic value.Current spot copper main " ripe spot ", because " ripe spot " is synthetic, and raw material sources is sufficient, so in moulding, the artwork variation that " ripe spot " makes, and not by the restriction of volume size, dissimilar circular engravure, high relief and bas-relief all can make." give birth to spot " because its starting material are rare, processed complex, cost is higher, and industrial scale is less, can only be used for manufacturing simple, that the scale of construction is small and exquisite ancient cooking vessel, stove, bottle etc.
The object of the invention is to propose a kind of new spot copper production method, adopt the spot coppery Ze Huali that present method is produced, and it is low to have cost, and simple to operate, color controllable is good, and the advantage such as can be mass-produced.Alleviate the short supply state of " raw spot " raw material to a certain extent, and provide technical guarantee for the casting of spot copper and retrofit.
Summary of the invention
The object of the present invention is to provide a kind of coloring liquid of spot copper, described coloring liquid is obtained by following preparation of raw material, copper sulfate 10 ~ 20 weight part, Repone K 6 ~ 15 weight part, potassium borate 4 ~ 12 weight part, cinnabar 1 ~ 4 weight part, distilled water 150 ~ 300 weight part.
Another object of the present invention is to provide the coloring liquid of described spot copper for the preparation of the method for spot copper, specifically comprise the following steps:
(1) put into diluted acid after foundry goods being polished and soak 3 ~ 5min, then foundry goods is cleaned up;
(2) foundry goods after cleaning in step (2) is put in aobvious spot solution reacts 5 ~ 10 minutes, the foundry goods after aobvious spot is cleaned;
(3) described coloring liquid is placed at normal temperatures and is obtained coloring liquid A in 6 ~ 8 days, and directly configuration obtains coloring liquid B;
(4) coloring liquid A is boiled directly water (consumption of coloring liquid A at least can drench whole foundry goods) on foundry goods afterwards, then foundry goods is put into the coloring liquid B after boiling and boil 25 ~ 40min, 8 ~ 14h is soaked after cool to room temperature, the height of coloring liquid exceedes foundry goods 6 ~ 10cm, rinses well and obtains dark red color spot copper casting.
The copper zinc alloy foundry goods of foundry goods of the present invention to be copper content be 93 ~ 97wt%.
Diluted acid of the present invention is hydrochloric acid, sulfuric acid or nitric acid, and its concentration is 10 ~ 12mol/L.
The composition of aobvious spot solution of the present invention is iron(ic) chloride 7 ~ 9wt%, hydrochloric acid 8 ~ 10wt%, Repone K or sodium-chlor 0.5 ~ 1wt%.
Cleaning process in described the present invention all adopts clear water to rinse.
The present invention compared with prior art has following advantages and effect:
(1) the spot copper color that coloring liquid of the present invention prepares is garnet or redness, can be used to prepare various artwork color and luster simple and unsophisticated magnificent, because the preparation process reaction times is longer, therefore the spot copper color controllable for preparing of described method is fine, the color of gained spot copper can be controlled according to the length of time and individual hobby, color is more thick and heavy can be grown some the time, and the more bright-colored time can be a little less, and preparation process is controlled flexibly;
(2) gained spot copper stability is fine, exposes not easy to change in atmosphere, facilitates waxing and processing further in subsequent process; Spot copper abundant raw materials of the present invention, production cost is low, simple to operate, and preparation process is not by the restriction of shape of product.
