Abstract

The invention discloses hot-rolling lubricant for silver and silver alloy plate strip. The hot-rolling lubricant adopts No.15 technical white oil as base oil, and the base oil is matched with multiple composite additives, wherein the additives comprise an anti-wear agent, an oiliness agent, an antioxidant, an antifoaming agent, a metal deactivator, an assistant, a friction improver and a dispersant. The lubricant has necessary medium separating, friction reducing and wear resistant performance, and is stable in chemical properties for rolled pieces and rollers, can prevent adhesion objects from generating on a rolling mill and a rolled product, and has good scale removing performance so as to remove rolling lubricant which falls on plate strips or roller tables possibly.

Description

Silver and alloy plate strip hot-rolled lubricant thereof

Technical field

The invention belongs to silver and alloy plate strip hot-rolled lubricant field thereof.

Background technology

Fine silver is a kind of argenteous metal of beauty, and it has good ductility, and its electroconductibility and thermal conduction are all the highest in all metals.Silver is commonly used to make the high physical apparatus element of sensitivity, and various automated installation, rocket, undersea boat, computer, nuclear machinery and communication system, a large amount of point of contact in all these equipment is all done by silvery.During use, each point of contact will work up to a million time, must wear-resisting and dependable performance, and can bear strict job requirement, silver can meet all requirements completely.If add rare earth element in silver, performance is just more excellent.With the point of contact that this silvery adding rare earth element is done, the life-span can extend several times.Element purposes: for alloyage, welding agent, silver foil, silver salt, chemical apparatus etc., and for aspects such as silver coin processed and end silver.Silver-colored or a kind of can be edible for humans metal, in the record that all useful silver foil encasing food of China and India and pill are taken.Silver or the food of some biology simultaneously.Due to the good characteristic that silver is exclusive, people once gave its currency and decoration dual value, and the silver dollar of sterling and China pre-peaceful liberation period is exactly the silver based on silver, copper alloy.Because silver-colored hot-rolled temperature is higher, its lubricant composition is more more complex relative to period element.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind ofly to be possessed necessary separate medium, reduce friction, wear-resistant performance, can prevent from producing bur on milling train and rolled products, has silver and the alloy plate strip hot-rolled lubricant thereof of good de-sludging performance.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 15 industrial white oils, coordinate multiple composite additive, its each component and mass percent thereof are:

Component	Content (mass percent)
		Base oil	Surplus
Anti-wear agent	5.0%～8.0%
		Oiliness improver	3.0%～5.0%
Oxidation inhibitor	0.5%～1.0%

Kilfoam	0.001%～0.003%
		Metal passivator	2.0%～3.0%
Auxiliary agent	2.0%～4.0%
		Dispersion agent	2.0%～3.0%
Friction improver	3.0%～5.0%

Base oil is No. 15 industrial white oils.

Anti-wear agent is the tritolyl phosphate of mass ratio 40% ~ 50% and the dioctyl sebacate compound of 60% ~ 50%.

Oiliness improver is the sulfurized castor oil of mass ratio 60% ~ 70% and the Uniphat A60 compound of 40% ~ 30%.

Oxidation inhibitor is the 2,6 ditertiary butyl p cresol of mass ratio 60% ~ 50% and the N-phenyl-a-naphthylamines compound of 40% ~ 50%.

Kilfoam is dimethyl silicone oil.

Metal passivator is 124 Triazole derivative.

Auxiliary agent is soap manufacturing paraffin.

Dispersion agent is polyisobutene succinimide.

Friction improver is industrial vaseline.

Silver of the present invention and alloy plate strip hot-rolled lubricant thereof, adopt oil based on No. 15 industrial white oils, coordinate multiple composite additive, comprise anti-wear agent, oiliness improver, oxidation inhibitor, kilfoam, metal passivator, auxiliary agent, friction improver, dispersion agent.Possess necessary separate medium, reduce friction, wear-resistant performance; All stable to rolled piece and its chemical property of roll; Can prevent from producing bur on milling train and rolled products, there is good de-sludging performance, to remove the rolling lubricant may fallen on Strip or roller-way.
