Abstract

The invention relates to a biodegradable rolled emulsified oil composition and a use thereof. The biodegradable rolled emulsified oil composition comprises, by weight, 60-80 parts of plant oil and synthetic ester, 2-10 parts of oleic acid or tall oil acid, 0-8 parts of at least one of sodium petroleum sulfonate, modified polyoxyethylene castor oil and alkylphenol polyoxyethylene ether, 0-10 parts of at least one of sulfurized fatty acid ester and phosphate ester, 1-5 parts of at least one of dodecanedioic acid and cyclohexene octanoic acid, 0.5-2 parts of di-tert-butyl methylphenol, 0.05-1 part of octyl diphenylamine, 0.05-0.2 parts of organosiloxane, and 0.5-2 parts of at least one of chloromethylthiazolinone and dibromonitrilopionamide. The composition can be used for technologic lubrication of a stainless steel plate band cold rolling process.

Description

technical field [0001] The invention relates to a biodegradable rolling emulsified oil composition and its application. Background technique [0002] In recent years, thanks to the development of my country's economy, the domestic metal processing industry has developed rapidly, and the consumption of metal processing fluids has increased year by year. At present, the non-renewable pure mineral oil-based metalworking oils in the market are gradually decreasing, and water-based metalworking fluids have become the mainstream products in the market, which has also brought a series of environmental problems. The emulsified metalworking fluid contains a large amount of mineral oil, which has poor biodegradability and is a substance that has a great impact on the environment. These waste liquids have low recycling value and are difficult to handle. The mineral oil has poor degradation ability in the environment, and direct discharge is harmful to humans. deterioration of the envi...
