AI Technical Summary

Problems solved by technology

This change may cause us to be unable to predict the service life of the precious metal paste, and the fluidity of the precious metal paste may also have unpredictable characteristics
[0004] In addition, the miscibility of specific silver thioresins is a limitation in many precious metal-containing formulations, which limits the choice of solvent and the amount of silver used

Effect test

Embodiment 1

[0025] 1998 grams of Venetian turpentine and 324 grams of sulfur were heated at 162°C for 4 hours in a container, and then cyclohexanone was added to make the total weight reach 4048 grams. After analysis, the sulfur content in the final product was 7.3%, and vulcanized Venetian turpentine was obtained.

Embodiment 2

[0027] In the solution that the methylene chloride of 48 gram silver carbonates and 70CC (milliliters) forms, stir and add 70 gram by the vulcanized Venetian turpentine that embodiment 1 obtains, experiment temperature is controlled at lower than 20 ℃. After the addition was complete, stir for one hour. Finally, 210 cc of ethanol was added. The silver resinate formed as a white oil immediately turned beige and then separated and washed with distilled water. It can be dissolved in cyclohexane, chloroform, benzene, toluene, xylene, monochlorobenzene, nitrobenzene, eucalyptol, terpineol, turpentine and rosemary oil to obtain a silver concentration of 39% by weight.

Embodiment 3

[0029] 25 grams of silver acetate (64.6 % silver content) were added with stirring to a solution of 101 grams of Cuban sulfide, 50 grams of cyclohexanone, and 25 grams of xylene. The addition was complete within 5 minutes and the operating temperature was raised to 100°C. After 5 minutes, the solution became two layers, one of which was a solution of silver resinate in xylene / cyclohexanone. Then separate, and wash with distilled water, the mass percentage of silver after testing is 20%.

Abstract

The invention provides preparation methods of a silver thio resinate. One preparation method includes the following steps: step A, carrying out a continuous reaction of Venice pine oil and sulfur for 4-6 hours with the reaction temperature of 160-170 DEG C, after standing, adding cyclohexanone, and thus obtaining vulcanized Venice turpentine; and step B, stirring to add the vulcanized Venice turpentine obtained in the step A into a solution formed by silver carbonate and dichloromethane, after addition is completed, stirring, then adding ethanol, allowing a formed white oily silver resinate to immediately turn into slight brown, then separating, cleaning with distilled water, and thus obtaining the silver thio resinate. The obtained silver thio resinate can be used as solvents of lavendin oil, lavender oil, turpentine, terpineol, rosemary oil and other essential oils. A decorative component containing the novel silver resinate can be melted at a relatively low temperature on decorative substrates such as glass substrates, and still has good viscosity.

Description

technical field [0001] The invention relates to materials used in the production process of precious metal preparations for the purpose of ceramic decoration, especially the preparation method of novel silver thio resin hydrochloric acid-mercapto compounds. Background technique [0002] Precious metal preparations containing gold thioresins for decorative purposes are described in known literature, for example Boudnikoff, Compt. rend., 196, 1898 (1933), and Chemnitius, J. Prakt. Chem. 117, 245 (1927). Gold thioresinates were prepared by reacting gold trichloride with sulfur-containing balsams or natural resins. [0003] Precious metal formulations of organic compounds of sulfur containing gold and silver for the purpose of ceramic decoration have been described in US Pat. No. 682,310 by Zsigmondy and Sprechsaal, 60, 313 (1927) by Chemnitius. Precious metal preparations containing silver (silver exists in the form of silver thioresinate) are prepared from natural products su...
