Description

Technical Field

[0001] The present invention relates to the technical field of copper oxide production, and specifically to a preparation process of highly active copper oxide. Background Art

[0002] Copper oxide powder is soluble in acids, insoluble in water, alcohol, ammonium chloride and potassium cyanide solutions, slowly dissolves in ammonia solution, and can also react with strong alkalis. It is mainly used for preparing petroleum desulfurizers, catalysts, rayon, ceramics, pesticides, glass, etc. The active copper oxide powder with a nanoscale particle size has the advantages of rapid acid dissolution, fine particle size, low impurities, large specific surface area, high quality, strong activity, etc. Therefore, it has more advantages than ordinary copper oxide powder in printed circuits, especially in spray cone materials and electronic materials, where it has an irreplaceable role compared to ordinary copper oxide powder.

[0003] In the patent document with the application number "CN202110080050.5" and the name "A process for producing high-purity active copper oxide by complexation replacement method", it is recorded that "①. Prepare a copper sulfate solution in a reactor, heat it to 40 - 50 °C, slowly add the complexing agent ammonia water until complexation is complete, and make all the copper sulfate solution react to become copper ammonium complex salt; ②. Continue to heat to and maintain 70 - 75 °C, slowly add liquid alkali to make the pH value of the chemical solution reach 12 until oxidation is complete, and decompose the copper ammonium complex salt to obtain copper oxide; ③. Finally, boil for 2 - 3 hours to drive out the separated ammonia; ④. Use the filter cake for filtration to obtain copper oxide particles. After filtration, wash the filter cake with boiling water to wash away the sulfate radicals contained in the filter cake. ⑤. Dry the filter cake in an oven (90 - 110 °C), and then transfer it to a muffle furnace to bake for more than 3 hours to remove the substances that make the copper oxide active, and the finished product is obtained. The activity of the copper oxide obtained by this process technology can reach less than 20 s each time, the particles are uniform, loose and flowing, and the fineness of the copper oxide particles can reach more than 300 meshes". Although the copper oxide manufactured by this patent document has certain advantages such as activity, its specific surface area is relatively insufficient and still needs further improvement.

[0004] For another example, in the patent document with the application number "CN201711271156.3" and the title "Porous nano-copper oxide and its preparation method", it is recorded that "The preparation method of this porous nano-copper oxide is as follows: Dissolve the soluble salt and the swelling agent in deionized water, stir until completely dissolved, add the copper precursor to the obtained solution, stir until completely dissolved, place the obtained solution under dynamic conditions for hydrothermal crystallization, cool the solution to room temperature after hydrothermal treatment, filter, wash, dry, and calcine to obtain porous nano-copper oxide. The copper oxide prepared by the method of the present invention has the advantages of large specific surface area, adjustable pore channels, controllable thickness, good dispersibility, high thermal stability, and rich five-coordinated copper, etc. It can not only be used in the catalytic field, but also be applied to fields such as ceramics, coatings, and pigments after further subsequent high-temperature calcination to obtain copper oxide, etc.". Although the copper oxide manufactured by this patent document has advantages such as a large specific surface area, its own activity performance is not good.
