Problems solved by technology

[0008] There are also some patents that use full oil-soluble formulations, such as JP8041486 (1996), which introduces the addition of 0.05-20wt% lipophilic carboxylic acid, sulfonic acid and anhydride, partial ester, amide and salt hot-rolled oil to inhibit black scale (iron oxide scale) to reduce roll wear, JP8143881 (1996) uses 30-90wt% high alkali value alkylphenol to improve adhesion, but these additives cannot have high extreme pressure, and the pyrolysis products of phenol are also toxic

example 1

[0070] In the 1000ml there-necked bottle that thermometer is housed, add 4g quaternary ammonium salt modified bentonite (Bentonite-34, American Lead Company produces), 200g granular nylon 6, and 200g pentaerythritol oleate, remove by high-purity nitrogen Oxygen in the bottle, keep the flow rate of nitrogen at 30-100ml / min, raise the temperature to 300-310°C under stirring, react for 5 hours, then pour the reaction mixture into a stainless steel container to cool and solidify, smash the solid into a diameter of about Particles of 1-2mm.

[0071] Add 5g of the above solid particles and 235g of pentaerythritol oleate into a 1000ml three-necked flask, gradually add 100g of 98% concentrated sulfuric acid under stirring, and keep the temperature below 50°C, then continue to stir for 1 hour, then gradually add 500ml of water to terminate the reaction, Sedimentation and separation of waste acid, gradually add 107g diethanolamine, stir for 1 hour, then dilute with water to obtain 1400g...

example 2

[0073] The preparation method is basically the same as Example 1, but in step 1, the modified bentonite is 8g, nylon 6 is 100g, and the carrier oil is 200g of trimethylolpropane oleate, and the mixing temperature is 250-260°C; in step 2 The alcohol amine is 214g of triethanolamine, and 1400g of orange-yellow viscous liquid is obtained. Take out 15g of it, 12g of lauryl amidopropyl betaine and 3g of naphthenic mineral oil, heat to 110-120°C under stirring, and dehydrate 2- After 3 hours, 21 g of a brown translucent paste, the intercalated clay antiwear agent B, was obtained.

example 3

[0075] The preparation method is similar to Example 1. In a 100ml beaker, add the above-mentioned 2g solidified product, add dropwise 10g of 98% concentrated sulfuric acid and 13g of castor oil under stirring, and keep the temperature below 4°C with water cooling. After 2 hours, 20 ml of water was added in portions for washing, and the spent acid was separated by centrifugation. Gradually add 15g of diethanolamine under stirring to obtain 33.3g of viscous liquid, mix with 1g of lauryl amidopropyl betaine and 10g of 150SN mineral oil, heat to 110-120°C under stirring, and dehydrate for 2-3 hours to obtain 35g of brown half Transparent paste, that is, intercalated clay antiwear agent C.

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...
