Problems solved by technology

There are many disadvantages of oil as a grinding fluid: 1. Large oil fumes, pungent smell, and many sludge sulfides, which affect the environment and endanger the health of workers; Third, products with high processing difficulty such as sapphire, electronic ceramics, NdFeB, magnetic materials, etc., put forward higher requirements for grinding fluid, and oil grinding fluid cannot fully meet the processing requirements. Require
In recent years, the industry has researched and developed water-soluble grinding fluids, but the quality of the existing water-soluble grinding fluids on the market is uneven, and it is often difficult to satisfy certain lubricity, sufficient cooling, and good Settling and better defoaming requirements

Abstract

The invention discloses a water-soluble grinding fluid and a preparation method thereof. The grinding fluid is prepared from, by weight, 5-20% of pyrazinecarboxamide, 5-20% of a water-soluble lubricant, 0.1-4% of a settling agent, 0.5-4% of a fungicide, 0.01-0.1% of benzotriazole, 0.1-0.5% of a defoaming agent and the balance water. The water-soluble lubricant is prepared by mixing polyether ester, triethanolamine, boric acid ester and polyethylene glycol in the weight ratio of (6-25):(5-20):(4-12):(1-3). The preparation method of the grinding fluid is simple, easy to implement and low in cost. The grinding fluid has the advantage of being good in lubricating property, cooling property, settling property, defoaming property, anti-rust property and cleaning property, and is high in water adaptation capability, good in chemical stability, lasting in low foaming state, excellent in grinding settling capability and oil stain resisting capability, long in service life and especially suitable for grinding of sapphire, electronic ceramic, neodymium iron boron, magnetic materials and other special materials which are hard and brittle and difficult to machine.

Description

technical field [0001] The invention relates to the technical field of grinding fluid and its preparation, in particular to a water-soluble grinding fluid and a preparation method thereof. Background technique [0002] The grinding fluid mainly plays the role of lubrication, cooling and cleaning in the grinding process, and the grinding fluid is required to have good settling properties at the same time. In traditional grinding, diesel oil and other oils are often used as grinding fluid. There are many disadvantages of oil as a grinding fluid: 1. Large oil fumes, pungent smell, and many sludge sulfides, which affect the environment and endanger the health of workers; Third, products with high processing difficulty such as sapphire, electronic ceramics, NdFeB, magnetic materials, etc., put forward higher requirements for grinding fluid, and oil grinding fluid cannot fully meet the processing requirements. Require. In recent years, the industry has researched and developed ...
