Embodiment Construction

[0012] The present invention will be described in detail below through specific examples.

[0013] A polishing solution for optical lenses, made of the following raw materials in parts by weight (kg): cerium hydroxide 10, cerium carbonate 5, thiourea 1, phytate 2, polyoxyethylene ether 4, sodium sulfate 2. Citric acid 3, oxidized alkylamine polyoxyethylene ether 3, zinc sulfate 2, methionine 1, additive 5, deionized water 300;

[0014] The auxiliary agent is made of the following raw materials in parts by weight (kg): boron nitride 5, silicon carbide 4, sodium silicate 1, potassium nitrate 2, benzimidazole 1, propylene glycol butyl ether 2, water-based acrylic polyurethane copolymer emulsion 4 , EDTA 3, Remibond 3, Gum Arabic 2.5, and water 50; the preparation method is to first add boron nitride, silicon carbide, gum Arabic, and Remibond to half the amount of water, grind for 1-2 hours, Then slowly add the remaining ingredients, slowly heat to 70°C-80°C, stir and react at 30...

Abstract

A disclosed polishing fluid for optical lenses is characterized by being prepared from the following raw materials in parts by weight: 10-12 parts of cerium tetrahydroxide, 5-7 parts of cerous carbonate, 1-2 parts of thiourea, 2-3 parts of inositol hexaphosphate, 4-5 parts of polyoxylethylene ether, 2-3 parts of sodium sulfate, 3-5 parts of citric acid, 3-5 parts of oxidized alkylamine polyoxethylene ether, 2-3 parts of zinc sulfate, 1-2 parts of methionine, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. The polishing fluid is safe, non-toxic, free of unpleasant smells and good in performances. By adding the auxiliary agent, the polishing fluid has good wear resistance, dispersity and cleaning property, and a polished surface is smooth, clean and bright. The polishing fluid is improved in quality and stable in quality, helps to shorten the flow time of a processing technology, is safe and environment-friendly, and is suitable for polishing of optical lenses.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a polishing solution for optical lenses and a preparation method thereof. Background technique [0002] In the manufacturing industry of optical lenses, the control of the preparation process is the key to the production of optical lenses. After the optical lens has been finely ground with abrasive fluid, there is still a crack layer about 2-3m thick on the surface. The method to eliminate this crack layer is polishing. Among them, for processing optical lenses, especially the polishing liquid used for grinding optical lenses has a great influence on this process. The traditionally used polishing liquid has the defects of long processing time, unstable product quality and poor overall operation efficiency. Contents of the invention [0003] The object of the present invention is to provide a kind of polishing liquid for optical lens and its preparation method. [0...
