Problems solved by technology

[0003] Compared with developed countries such as the United States and Japan, my country's polishing industry still has a large gap. At present, the polishing liquid used for the precision processing of optical instrument glass components mainly depends on imports. There are few domestic zirconia polishing liquid products and manufacturers, and the performance cannot reach Precision Polishing Requirements
Although imported products have good effects, they are expensive, so independent research and development of high-performance zirconia polishing fluid has great economic and practical significance

Embodiment 1

[0028] The specific preparation steps of this embodiment are as follows (the unit of measurement in parts by weight in this example is 1 kilogram):

[0029] 1. Prepare materials: get 2 kilograms of zirconium oxychloride and 20 grams of Fe(NO 3 ) 3 9H 2 O, standby;

[0030] 2. Preparation of symbiotic solution: firstly, the spare zirconium oxychloride is dissolved in 10 kilograms of deionized water to become an aqueous solution of zirconium oxychloride; then, the spare Fe(NO 3 ) 3 9H 2 O is added to the zirconium oxychloride aqueous solution, stirred until completely dissolved, and becomes an iron-zirconium symbiotic solution, which is set aside;

[0031] ③. Preparation of symbiotic precipitation: Slowly add ammonia water with a concentration of 20% into the spare iron-zirconium symbiotic solution, and keep stirring until all zirconium ions and iron ions are precipitated, and continue to add ammonia water, adjust the pH value to 5-7, and prepare Zirconium hydroxide and fe...

Embodiment 2

[0038] The specific preparation steps of this embodiment are as follows (the unit of measurement in parts by weight in this example is 10 kilograms):

[0039] ①, material preparation: take 20 kilograms of zirconium nitrate and 400 grams of FeCl respectively 3 ·6H 2 O, standby;

[0040] 2. Preparation of symbiotic solution: slowly add spare zirconium nitrate into 100 kg of rapidly stirred deionized water to form zirconium nitrate aqueous solution; then, add spare FeCl 3 ·6H 2 O is added to the zirconium nitrate aqueous solution, stirred until it is completely dissolved, and becomes an iron-zirconium symbiotic solution, which is set aside;

[0041] ③. Preparation of symbiotic precipitation: Slowly add 10% NaOH solution into the spare iron-zirconium symbiotic solution, and keep stirring until all zirconium ions and iron ions are precipitated, and continue to add NaOH solution to adjust the pH value to 5-7. Make the symbiotic precipitation that zirconium hydroxide and ferric h...

Abstract

The invention discloses an iron-doped zirconium oxide polishing solution, and relates to the technical field of preparation of polishing materials. The iron-doped zirconium oxide polishing solution is prepared from water-soluble inorganic zirconium salt, soluble trivalent ferric salt, alkali, zirconium carbonate, additives and a pH value modifier. The method comprises the preparation steps of material preparation, symbiotic solution preparation, symbiotic precipitate preparation, washing, drying, roasting, grinding and stirring dispersion; the method has the characteristics that the cutting rate is good and no obvious defects are generated on the surface of a polished material; the iron-doped zirconium oxide polishing solution prepared by using the method is suitable for the processing field of high-grade optical instruments, and particularly can be applied to polishing flexible glass.

Description

Technical field: [0001] The invention relates to the technical field of preparation of polishing materials, in particular to a preparation method of iron-doped zirconia polishing liquid. Background technique: [0002] At present, the market demand for high-precision and large-diameter optical glass is gradually increasing, and the demand for high-hardness polished products is also increasing day by day. Zirconia polishing liquid has a good effect on glass surface processing, especially the polishing of soft glass, and has great market demand and development prospects. [0003] Compared with developed countries such as the United States and Japan, my country's polishing industry still has a large gap. At present, the polishing liquid used for the precision processing of optical instrument glass components mainly depends on imports. There are few domestic zirconia polishing liquid products and manufacturers, and the performance cannot reach Precision polishing requirements. A...
