Abstract
The present invention relates to a silvery white rare earth ceramic liquid gold. The present invention is prepared by mixing organic resin, nitration rosin fillers and dissolution oil (of metals such as platinum, palladium, gold, silver, bismuth, rhodium, praseodymium, etc.) which are used as color formers and secondary components. A novel coloring system is formed by leading in the metallic silver and a rare earth element of the praseodymium, so the present invention does not comprise or comprise a small amount of gold, the gold consumption and the noble metal consumption are reduced, the production cost is greatly reduced, and the present invention has the advantages of pure color, high glossiness, high whiteness, good use performance and high chemical stability, and can be widely used of the painted decoration of the hard porcelain, artificial porcelain, stoneware and fine pottery products.
Description
What the present invention relates to is a kind of silvery white rare-earth ceramic metal coating, belongs to the liquid decorative material that hard-paste, soft porcelain, delicate china, glass and enamelware colored drawing are used.
At present, in silvery white ceramic Jinsui River of domestic production, all contain gold, remaining precious metal also has platinum, rhodium, bismuth, palladium etc.The content of metallic element is in for example common silvery white ceramic liquid palladium gold: gold 6.0%, palladium 1.6%, rhodium 0.15%, bismuth 0.22%, chromium 0.04%: the constituent content that silvery white ceramic platinum underwater gold belongs to is: gold 2.7%, platinum 0.9%, rhodium 0.08%, bismuth 0.14%, chromium 0.02%.The former color bodies is gold---palladium, the latter's color bodies are a gold---platinum, because bullion content is higher in these two kinds of Jinsui River, and all contains gold, take national specified gold index, so cost is higher, and range of application also is restricted.
Introduced the ceramic Jinsui River of a kind of silvery white in the English Patent 1527294, wherein the content of each metallic element is: platinum 3.9%, and silver 0.875%, bismuth 0.52%, though wherein do not contain gold, other bullion content height, production cost is also higher.
Purpose of the present invention is overcoming (liquid palladium gold) silvery white ceramic Jinsui River that above-mentioned weak point of the prior art provides (the platinum water) that does not contain gold or contains a small amount of gold, other noble metal dosages are low simultaneously, production cost is low, and silvery white pure, glossiness and degree is high certainly, use properties and chemical stability are good, and wear resisting property is good.
Silvery white rare-earth ceramic metal coating of the present invention has platinum water and liquid palladium gold, by introducing metallic element silver and rare earth element praseodymium, has formed new color development system, makes it not contain gold or contains gold less, reduces the consumption of other precious metal simultaneously.Wherein platinum water is with platinum---palladium---praseodymium system color development, liquid palladium gold is with palladium---and its weight percent of gold---silver---praseodymium system color development is formed:
Platinum water: the organic resin 18～59% of metallic element platinum, palladium, silver, bismuth, rhodium and rare earth element praseodymium, nitrated rosin weighting agent 31～62%, dissolving oil 10～25%; Liquid palladium gold: the organic resin 29～81% of metallic element palladium, gold and silver, bismuth, rhodium and rare earth element praseodymium, nitrated rosin weighting agent 13～33%, dissolving oil 5～39%.
Wherein the content of each metallic element is:
Platinum water liquid palladium gold
Platinum 0.8～2.5% palladium 0.8～3%
Palladium 0.8～2.5% gold medal 2～4%
Silver 0.2～0.8% silver medal 0.4～1.2%
Bismuth 0.2～0.6% bismuth 0.2～0.6%
Rhodium 0.03～0.1% rhodium 0.03～0.1%
Praseodymium 0.05～0.2% praseodymium 0.05～0.3%
Platinum, palladium, praseodymium are chromogenic reagent in platinum water, and silver, bismuth, rhodium are auxiliary composition; Palladium, gold and silver, praseodymium are chromogenic reagent in liquid palladium gold, and bismuth, rhodium are auxiliary composition.Wherein bismuth is a metal solvent, and major function is to improve sticking power and the wear resistance of silvery white film on the porcelain base; Rhodium is the high temperature fixative, and its major function is to make color bodies tie up to high temperature (more than 800 ℃) to continue to keep silvery white; The adding of silver has certain effect to wear resistance and the gloss that improves silvery white film; Introduce the rare earth element praseodymium, the alloy grain of decapacitation refinement precious metal improves beyond the color development effect, can also form superalloy with the metal solvent bismuth, to improving glossiness, whiteness and temperature tolerance tangible effect is arranged, and can also reduce the usage quantity of rhodium simultaneously.Above-mentioned each 8 component in the prescription all has effect separately, replenishes mutually again simultaneously, promotes, reaches an ideal purpose jointly.
The preferable range of metal element content is in the silvery white rare-earth ceramic metal coating of the present invention:
Platinum water liquid palladium gold
Platinum 1～2% palladium 1～3%
Palladium 2～3% gold medals 2～4%
Silver 0.3～0.6% silver medal 0.8～1.2%
Bismuth 0.3～0.5% bismuth 0.2～0.5%
Rhodium 0.05～0.1% rhodium 0.05～0.1%
Praseodymium 0.1～0.2% praseodymium 0.1～0.3%
Above-mentioned metallic element is introduced with the form of its organic resin, and its preparation method is as follows:
Resin platinum: PtCL4 weight be 1 with weight be 1～3 vulcanized oil, weight is that 1～2 dissolving oil reaction forms;
The resin palladium: PdCL2 weight be 1 with weight be that 1～3 vulcanized oil, weight are that 1～2 dissolving oil reaction forms;
