example 1

[0071] Add 2 grams of sodium dodecylbenzenesulfonate, 5 grams of sodium carboxymethylcellulose, 0.5 grams of attapulgite, and 500 mL of distilled water into a beaker, stir for 3 hours, and then pour into an ultrasonic cleaner for ultrasonic dispersion (frequency 60 Hz) After 1 hour, pour it out, stir until it is completely dissolved, and prepare a suspension A containing 0.4% sodium dodecylbenzenesulfonate, 1% sodium carboxymethylcellulose, and 0.1% attapulgite.

example 2

[0073] According to the method of Example 1, a suspension B with attapulgite content of 0.4%, sodium lauryl sulfate content of 1%, and sodium carboxymethylcellulose 1.5% was prepared.

example 3

[0075] Take 5 grams of TW-80 (polyoxyethylene sorbitan monooleate), 5 grams of montmorillonite, 15 grams of sodium alginate, 15 grams of gluconic acid, 500ml of tap water (in Beijing area), stir for 1 hour and then ultrasonic (20HZ) for 30 minutes, and prepare a suspension sample C containing 1% TW-80, 1% montmorillonite, 3% sodium alginate, and 3% gluconic acid.

Abstract

A hot-pressed oil composition from water dispersible clay consists of lubricant base with viscosity 5-300mm2/s at 40 degree, 0.1-20wt% sulfur-contained extreme pressure agent from alkyl polysulfide, mineral oil sulfide and thiopoly alcohol ester, 0.1-15wt% phosphor-contained anti-scuff agent from organic phosphate, phosphonate ester, phosphate ester, acid amine salt organic phosphate, amine salt phosphate ester, phosphoamidster, dialkyl phosphateodithioate, dimercaptothioliazole phosphorodithioate and acid phosphate imidazoline salt and 0.001-0.5wt% clay wear-resistant anti-slip agent emulsified by clay suspensoid. It has excellent dispersibility, abrasion resistance, lubricity and degradability and has no environmental pollution.

Description

technical field [0001] The invention relates to a hot rolling oil composition. Background technique [0002] The use of hot-rolling oil is a new technology in the field of modern steel rolling. Early hot-rolling did not use oil but was lubricated with water. Later, hot-rolling oil was directly used to lubricate the rolls. Its ingredients include mineral oil, animal and vegetable oils, and synthetic fatty acids. Lubricating oil, causing great pollution. The lubricity of hot rolling has been greatly developed in the past ten years. At present, many large-scale hot rolling mills use the lubrication technology of water and oil co-spraying instead of pure oil lubrication. During the rolling process, a very small amount of hot rolling oil and A large amount of water (more than 99.5%) is mixed, forced to emulsify, sprayed onto the surface of the work roll, and the emulsion is brought into the deformation zone through the rotation of the roll, which not only effectively cools the r...
