Description

Molten gold resisting high-temp sinter and production method thereof
One, technical field
The present invention relates to molten gold resisting high-temp sinter and preparation method thereof, belong to the technical field of ceramic decoration coating material production.
Two, background technology
Bright liquid gold is in Jinsui River again, is a kind of proof gold 10~12% that contains, and is added with the compound of metals such as a small amount of rhodium, chromium, bismuth, the brownish black thick liquid in oil medium.It can impose on the Ceramic glaze with modes such as brushing, stamps, and with weak fire heating (about 300 ℃), oil is evaporated and burns then, and gold-containing compound decomposes and leaves over down jewelly gold as thin as a wafer layer, can be bonded on the glaze securely during reheat to 750 ℃.Doing to decorate on the ceramic glaze with Jinsui River is one of cheap and good-quality gold trailing.Before the present invention, Jinsui River generally makes by following technology: gold is dissolved in chloroazotic acid obtains hydrochloro-auric acid, preparation sulfuration face cream and ammoniumper chlorate gold; Prepare golden organic compound; Preparation resinous acid chromium, bismuth resinate, resinous acid rhodium and ester (solvent); Prepare Jinsui River of necessary denseness (concentration).The subject matter that exists is that high temperature sintering resistant and sticking power are relatively poor, in Jinsui River of various prescriptions, the product that can high temperature resistant sintering reaches more than 850 ℃ is arranged seldom.There are gold and the sintering temperature contacted ceramic of people should be high more good more and decorate, so that the harmful material of some in the ceramic substrate material (as lead etc.) can in high-temperature sintering process, remove.Along with the relieving of national gold policy, the consumption of gold in ceramic decoration is increasing, so Jinsui River that R and D have a high temperature resistant sintering character has very big realistic meaning for ceramic decoration.
Three, summary of the invention
1, goal of the invention: the purpose of this invention is to provide a kind of molten gold resisting high-temp sinter and production method thereof with resistance to elevated temperatures and strong adhesion.
2, technology contents: a kind of molten gold resisting high-temp sinter, the components by weight percent in this Jinsui River are gold 5~10%, thorium 2.2~3.0%, rhodium 0.1~0.3%, antimony 0.1~0.8%, lead 0.3~0.4%, bismuth 1.0~1.4%, and all the other are mixed solvent; It is characterized in that described mixed solvent is is that 2~9% chloroform, 1~8% oil of mirbane mix by the turps of weight 24%, 41% star aniseed oil, 25% dibutyl phthalate and surplus.
The method of its preparation is at first making resinate respectively with thorium nitrate 99.99004323A8urity, Trichlororhodium, butter of antimony, above-mentioned three kinds of resinates are mixed, the weight content that makes thorium in the mixture is 5~10%, the weight content of rhodium is 0.5~1.0%, the weight content of antimony is 0.6~1.8%, obtains high temperature resistant Jinsui River additive; After gold perchloride made high gold trichloride ammonium, obtaining weight Gold Content with the reaction of sulfuration face cream was 50~65% resinous acid gold solid; Lead nitrate and Bismuth trinitrate are made resinate respectively, the two is mixed, making content plumbous in this mixture is 3.0%~5.0%, and the content of bismuth is 11.0%~17.0%, obtains Jinsui River sticking power toughener; High temperature resistant Jinsui River additive, resinous acid gold solid and Jinsui River sticking power toughener that above three parts are made mix, and dilute with mixed solvent at last.
3, positively effect: the fusing point of gold is 1064.43 ℃, and chemical property is very stable, is unique metal that does not at high temperature react with oxygen.And the decomposition temperature of the organic compound of gold is generally lower, gold is made organic compound, and to be applied to largest benefit on the ceramic surface again be that the distribution of gold is more even, and can form alloy in sintering process with other metal (must make organic compound in advance).Therefore, technological thought of the present invention is: in the suitable organic compound of gold, adding can form the organic compound of other metal of high temperature alloy with gold, under the prerequisite of the color effects that does not influence golden surface decoration, improve the high temperature resistant sintering character in Jinsui River, difference according to ceramic substrate material adds the different frit that can improve surface decoration gold sticking power simultaneously, thereby reaches the high temperature resistant sintering in raising Jinsui River and the purpose of sticking power.
