Abstract

The invention discloses a cooling liquid for lens glass processing. The cooling liquid consists of the following components in percentage by weight: 5-15% of an antirust agent, 1-2% of a bactericide, 5-20% of a surfactant, 6-18% of a lubricant, 5-15% of an anti-scaling agent and the balance of pure water. The cooling liquid for lens glass processing disclosed by the invention is good in permeability, capable of preventing chip accumulation on the surface of a grinding wheel bar and constantly keeping the cutting capacity of the surface of the grinding wheel bar; the cooling liquid can improve the surface smoothness of a workpiece and reduce the occurrence of edge breakage and bad scratching; the PH value is around 7, and the cooling liquid is neutral and odorless, free from harm to human bodies and cannot cause skin allergy; after cutting, glass is easy to clean, and processing equipment is free from dirt accumulation as well, strong in anti-rust property and is not easy to become rusted; and the cooling liquid is strong in antibacterial capacity, stable in performance, free from environmental pollution and long in service life.

Description

technical field

[0001] The invention relates to a cooling liquid, in particular to a cooling liquid used in CNC machining of lenses of mobile phones and tablet computers. Background technique

[0002] In the process of optical lens glass processing, the diamond grinding wheel grinds glass, and the friction will generate heat. If there is no coolant, the grinding wheel will be damaged quickly, the processing ability will be lost, and the processing of the lens will be bad. Therefore, it is necessary to add coolant to improve the grinding wheel rod. processing status and improve yield.

[0003] The cooling liquid described in Chinese Patent No. 200710026163.7 contains nitrite and dichromium ions, which pollutes the environment.

[0004] The PH value of the coolant described in Chinese patent 201310308199.X is about 9. Although it is weakly alkaline, human skin is weakly acidic, and allergies may occur.

[0005] In view of this, it is in line with the needs of social developm...
