preparation example Construction

[0052] The preparation method of the above-mentioned cooling liquid for optical processing is as follows: take surfactant, lubricant, antirust agent, pH value regulator, bactericide, defoamer and distilled water according to the weight ratio, and place the surfactant in turn at room temperature , lubricant, antirust agent, pH regulator, bactericide, and defoamer are added to distilled water, stirred evenly, and the cooling liquid for optical processing of the present invention can be made.

[0053] The surfactant of the present invention adopts anionic surfactant, which has good permeability and can wet a large amount of dust generated, thereby minimizing the amount of dust entering the air, and most of the generated dust liquid away. At the same time, the anionic surfactant used has good glass shavings separation and settling properties, can discharge waste swarf in time, is not easy to cause blockage of the liquid supply system, and prevents secondary friction during process...

Abstract

The invention relates to cooling liquid for optical processing. The cooling liquid consists of the following ingredients in percentage by weight: 10 percent to 20 percent of surfactants, 5 percent to 20 percent of lubricants, 0.5 percent to 3 percent of anti-rusting agents, 3 percent to 8 percent of pH value conditioning agents, 0.05 percent to 0.5 percent of sterilizing agents, 0.05 to 0.5 percent of defoaming agents and the balance distilled water. The cooling liquid for optical processing has the advantages that glass chip separation performance and settleability are excellent, the environmental adaptation is wider, the stability is batter, the foaming is low, the rinsing is easy, the wettability is good, no damage is generated on the glass surface, no phosphorus element is contained, no peculiar smell, no poison or no corrosivity is generated, safety and reliability are realized, combustion and explosion are avoided, the environment is not polluted, the use cost is low, and the transportation and the storage are convenient.

Description

technical field [0001] The invention relates to a cooling liquid, in particular to a cooling liquid used in optical processing. Background technique [0002] During the optical glass cooling process, after the diamond abrasive tool is used for a period of time, glass shavings and abrasive shavings will block the abrasive tool, resulting in passivation of the abrasive tool and reduced processing capacity. Water-based lubricating coolant is required to improve the work of the diamond abrasive tool State, improve processing efficiency. [0003] Chinese Patent No. 200710026163.7 discloses a cooling liquid for optical processing, which includes an antirust agent. The phosphate, nitrite, and heavy metal ion potassium dichromate contained in the antirust agent will pollute the water environment. [0004] In view of this, it is urgent to develop a high-efficiency optical processing coolant to replace the traditional high-pH, non-environmentally friendly coolant. Contents of the i...
