The invention provides an all-synthetic
grinding fluid, aiming at the problems of poor lubricating property and
surface smoothness, low precision, short
rust-proof period of the traditional
grinding fluid and adverse
impact on environment in the discharging process of the traditional
grinding fluid. The all-synthetic grinding fluid puts emphasis on comprising the following components in percentage by weight: 0%-15% of extreme-pressure additives, 0%-15% of lubricating agents, 15%-25% of dispersing agents, 15%-25% of
surface active agents, 15%-25% of
rust-proof components, 0.5%-1% of antifoaming agents, 0.5%-1% of foam suppressors and the balance of water, wherein the extreme-pressure additives and the lubricating agents are one or more than one of polyether, organic
carboxylic acid and organic
phosphate; the dispersing agents and the
surface active agents are one or more than one of JFC, AEO9,
polyethylene glycol and
diethylene glycol; the
rust-proof components are one or more than one of organic
carboxylic acid,
triethanolamine, diethanol amine, organic
molybdenum and
sodium borate; and the antifoaming agents and the foam suppressors are one or more than one of organic
silicon and the organic
phosphate. The invention has good extreme-pressure
lubricity, long rust-proof period and small foam without environmental
pollution.
