Abstract
The present invention relates to volatile lubricating oil for machining metals, which is composed of 90.5 to 99.6 wt% of base oil with refining and narrow fraction, 0.2 to 8 wt% of nontoxic oiliness agent, 0.01 to 0.08 wt% of surface active agent and 0.1 to 1.5 wt% of antioxidant by taking the gross weight of the lubricating oil as reference. The volatile lubricating oil for machining metals has the advantages of good safety, anticorrosion performance, lubrication performance, hydrophilicity and versatility. The lubricating oil is suitable for the punch machining of aluminum, copper and alloy foil materials, and can be used for the lubrication of machining technology of expansion pipes and bend pipes made of copper and alloy pipe materials. Human skin has no allergic reaction after contacting the lubricating oil, and the lubricating oil belongs to extremely slight poison oil products.
Description
The invention belongs to lubricating oil composition, exactly, is a kind of volatile lubricating oil for machining metals.
The ductility of non-ferrous metal aluminium, copper and alloy thereof is good, will hang down concerning relative ferrous metal of the requirement of lubricant and stainless steel, but corrodibility is had relatively high expectations.The lubricant of industrial normal use mainly contains machinery oil, vegetable and animals oils or machinery oil and is aided with additive.Though these oil can satisfy the requirement of lubricated aspect, because viscosity is big, volatility is poor, and cooling performance is low, thereby process velocity and processing work surface clearness are all had disadvantageous effect.In order to clean the processing work surface, to use solvent cleaning toward contact, reduced production efficiency, increased facility investment.In order to ensure the surface clearness of processing work, adapt to the lubricating requirement of novel high speed pressing equipment, offshore company takes the lead in developing novel volatile-type non-ferrous metal aluminium, copper and alloy sheets thereof, foil punching oil, as the RF270 of Shell Co. Ltd's production.The RF270 outward appearance is a white, and the smell gentleness has good lubricating property and antiseptic property, but security and versatility are not really desirable.
Domestic similar patent application has 90104959,90110038 etc.90104959 consist of wherein: 3～40%, No. 360 pressed oils 45～84% of medium viscosity mineral oil, nontoxic extreme pressure agent 0.3～11%, nontoxic oiliness improver 1.7～5%, defoamer 0.001～0.01%.This prescription volatility and versatility are relatively poor.
90110038 composed as follows: molecular weight a.0.5～1.5% is 5～200,000 polyacrylamides; B.0.5～2% aliphatic alcohol polyethenoxy phosphate kalium salt; C.1.5～3% alkylphenol polyoxyethylene; D.1～1.3% borax; E.1～3% trolamine, surplus is a water.The antiseptic property of this prescription is relatively poor.
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of volatile lubricating oil for machining metals with good security, preservative property, oilness, wetting ability and versatility is provided.
Consisting of of volatile lubricating oil for machining metals provided by the invention: with the lubricating oil gross weight is benchmark, a.90.5～99.6 the refining narrow fraction base oil of heavy %; B.0.2～8 weigh the nontoxic oiliness improver of %; C.0.01～0.08 weigh the tensio-active agent of %; D.0.1～1.5 weigh the oxidation inhibitor of %.
Said refining close-cut fraction base oil be meant the fraction scope be no more than 50 ℃, aromaticity content less than 1%, Saybolt color greater than+25, sulphur content is less than the fraction of diesel oil of 10ppm.The content of base oil can be 90.5～99.6 heavy %, preferred 92.8～99.1 heavy %.
Said nontoxic oiliness improver is selected from Fatty Alcohol(C12-C14 and C12-C18), lipid acid or fatty acid ester, as: C
12～C
18Alcohol, C
12～C
18Acid, methyl stearate, butyl stearate, Laurate methyl, coconut oil methyl esters etc.The content of oiliness improver can be 0.2～8 heavy %, preferred 0.5～6 heavy %
Said tensio-active agent is polyxyethylated alkylphenol or fatty acid acyl amine, as lauric amide.The content of tensio-active agent can be 0.01～0.08 heavy %, preferred 0.02～0.06 heavy %.
Said oxidation inhibitor is phenol type antioxidant, as 2, and 6-di-t-butyl-4-cresols, 2,4-dimethyl-6 tert-butyl phenol, 2,6-di-tert-butylphenol and tertiary butyl mixed phenol etc.The content of oxidation inhibitor can be 0.1～1.5 heavy %, preferred 0.3～1.2 heavy %.
Volatile lubricating oil for machining metals provided by the invention has the following advantages:
(1) suitable with RF270 aspect volatility, than 90104959 good, but because of flash-point than RF270 innage, because of
And the security of using is better.
(2) aspect antiseptic property, be better than 90110038, suitable with RF270.
(3) suitable with RF270 aspect lubricity.
(4) aspect hydrophilicity, be better than 90110038 and RF270.
(5) aspect universal performance, be better than 90104959 and RF270.Oil of the present invention can be used for the pipe processing of rising of the punch process of aluminium, copper coin, foil and tubing simultaneously, and 90104959 pipes that can only be used to rise, and RF270 can only be used for punching, and the effect that is used to rise when managing is bad.
Therefore volatile lubricating oil for machining metals provided by the invention has good security, preservative property, oilness, wetting ability and versatility, and over-all properties is better than the product RF270 of Shell Co. Ltd and Chinese patent application 90104959 and 90110038.Lubricating oil provided by the invention is applicable to the punch process of aluminium, copper and alloy sheets thereof, foil, also can be used for the pipe processing technique that rises lubricated of aluminium, copper and alloy pipe thereof, and can not cause disadvantageous effect to the hydrophilic aluminium foil surface.This lubricating oil can not cause the human body skin anaphylaxis, through the small white mouse test, belongs to atomic malicious oil product.
The invention will be further described below by embodiment.
