Abstract

A microemulsified liquid for machining metals contains sodium petrosulfonate, basic oil, span-80 and tween emulsifier, phenyltriazole, alcohol-amine match, benzoic acid, phenyltriazole derivative, 2-6-di-tert-butyl p-cresol, castor-oil polyoxyvinyether, bactericiding antimildew agent and water. Its advantages are high stability, high antirusting and lubricating performance, and high cooling speed.

Description

Metal processing microemulsion

Technical field:

The present invention relates to a kind of be used for metal especially copper and the alloy course of processing thereof as lubricated, cooling, antirust and peace and quiet fluid composition.

Background technology:

In process of metal working, people generally adopt oil base working fluid or oil in water emulsion, and the oil base working fluid has good lubricity, and its weak point is cleaned for being difficult to, and easily stays spot, and environmental pollution is serious; Oil in water emulsion has good cooling, its weak point is: need could stablize in high pH value scope, propose extremely harsh requirement to mould inhibitor, cause its emulsion putrid and deteriorated smelly easily, the easy floating oil instability of emulsion shortens the working fluid work period.

Summary of the invention:

The objective of the invention is to overcome the weak point of the above oil base working fluid and oil in water emulsion, a kind of novel metal working fluid between oil base working fluid and oil in water emulsion is provided, make it both have oil base working fluid good lubricity, possess the good cooling of oil in water emulsion again.

The present invention, its components in weight percent is: petroleum sodium sulfonate 10-30%; Base oil (10-15mm ²/ s40 ℃) 20-60%; Emulsifying agent 15-30%; Rust-preventive agent 0.5-2%; PH buffer reagent 2-10%; Corrosion prevention rust preventer 2-5%; Metal passivator 0.1-0.5%; Oxidation inhibitor 0.1-0.5%; Kilfoam 0.1-1%; Biocide mildewcide 0.1-1%; Water 1-30%.

The present invention, described emulsifying agent can for Arlacel-80 and tween by 1: the proportioning of 1-2 constitutes; Rust-preventive agent can be 124 Triazole; The PH buffer reagent can be the hydramine compound; Corrosion prevention rust preventer can be phenylformic acid; Metal passivator can be the 124 Triazole derivative; Oxidation inhibitor can be the 2-6-ditertbutylparacresol; Kilfoam can be castor oil polyoxyethylene ether, and biocide mildewcide can be three red oil.

The present invention is a primary emulsion owing to adopt with the nonionic surface active agent, and emulsion is very stable in broad pH value scope and in the wide temperature range.This is because its emulsified particle thin (diluent is translucent to near-transparent), and carrying out metal with it, to add the man-hour intuitive strong, finds the fault in the course of processing easily, corrects so that in time find.Particularly adopt sapn, twain series emulsifier, have nontoxic, nonirritant, easily degraded does not produce environmental pollution, advantage such as prevent that the workman from coming to harm.Simultaneously, this emulsifying agent has multiple functional, integrate lubricated, cooling, antirust, cleaning, can overcome the drawback of common emulsifying agent functional limitation, therefore, microemulsion of the present invention has characteristics such as oilness is good, rust-preventing characteristic is splendid, speed of cooling is fast, spatter property is good, except being fit to copper and alloy precision work thereof, also be fit to the precision work of multiple non-ferrous metal, purposes is more extensive.

Embodiment:

The preparation of metal processing microemulsion can be by 12% petroleum sodium sulfonate, 40% base oil (10-15mm ²/ s40 ℃), 10% Arlacel-80,12% tween, 1% 124 Triazole, 8% hydramine compound, 3% phenylformic acid, 0.5% 124 Triazole derivative, 0.5% 2-6-ditertbutylparacresol, 0.5% castor oil polyoxyethylene ether, 0.5% biocide mildewcide and 12% water allotment constitute.

Its allocating technology is: at first, petroleum sodium sulfonate, base oil, hydramine compound and the water of formula ratio is at room temperature stirred into mashed prod, be warming up to 90-100 ℃ then gradually, become even diaphanous oily matter.Afterwards, be cooled to 80 ℃ at once, and under (insulation) stirring state with addings such as the sapn of formula ratio, tween, phenylformic acid, after treating the solution clear, be cooled to 50-60 ℃, add 124 Triazole derivative, the 2-6-ditertbutylparacresol of formula ratio again, under agitation add castor oil polyoxyethylene ether and biocide mildewcide at last, make it to become the oily liquids of homogeneous transparent, i.e. concentrated solution.Generally the concentrated solution thin up is become the concentration of 1-10% to use.

Metal processing microemulsion physics and chemistry technical indicator is as shown in the table:
