The invention relates to the technical field of diamond wire cutting of hard and brittle materials such as glass products, quartz optical products, crystal products, sapphire glass, magnetic materials and the like, and particularly relates to a fully synthetic glass cutting fluid and a preparation method thereof.

Background

In recent years, the demand of high-end optical glass is gradually increased, higher requirements are put forward on the manufacturing process and the technology, glass cutting is an important part in the preparation of optical glass products, and the cutting efficiency and the cutting quality can be greatly improved by using a diamond wire cutting machine.

Cutting oil is needed in the cutting process of the diamond wire cutting machine, belongs to a high-pollution product, and has a large influence on the use environment. Particularly, the traditional synthetic cutting fluid contains an organic silicon defoaming agent, so that the stock solution is easy to delaminate, a pipeline is easy to block after long-term use, and meanwhile, the problems of high Chemical Oxygen Demand (COD), serious pollution, poor cutting environment condition, medium recovery and the like are solved.

Therefore, there is a need to prepare an environmentally friendly aqueous cutting fluid that can solve the above problems.
