CN103666671B - Cold rolling lubricant for zinc and zinc alloy foil - Google Patents

Abstract

A cold rolling lubricant for zinc and zinc alloy foil is characterized by adopting No. 5 industrial white oil as basic oil and compounding multiple kinds of composite additives including an anti-wear agent, an oily agent, an antioxidation and corrosion prevention agent, an anti-foam agent, an anti-emulsification agent and a friction improver. The cold rolling lubricant has good cooling, cleaning, lubricating, diffusing, high temperature resisting and stable thermooxidizing performances, can better keep certain continuity and thickness of an oil film, reduces friction coefficient and phenomena of adhesion between a roller and a rolled piece during cold rolling, and can satisfy requirements on board shape and surface finishment.

Description

Zinc and alloy foil cold-rolling lubricant thereof

Technical field

The invention belongs to zinc and alloy foil cold-rolling lubricant field thereof.

Background technology

Zinc is the slightly light blue metal of a kind of silvery white, and density is 7.14g/cm ³, fusing point is 419.5 DEG C.At room temperature, property is more crisp; When 100 ~ 150 DEG C, deliquescing; After 200 DEG C, become fragile again.The chemical property of zinc is active, and in air at normal temperatures, the thin and zinc subcarbonate film of densification of Surface Creation one deck, can stop further oxidation.After temperature reaches 225 DEG C, zinc vigorous oxidation.In modern industry, have indelible status for battery manufacture, be a considerable metal.Zinc be mainly used in iron and steel, metallurgy, machinery, electrically, chemical industry, light industry, military affairs and medicine and other fields.Zinc alloy is that base adds other elementary composition alloys with zinc.The alloying element often added has the Low Temperature Zn alloys such as aluminium, copper, magnesium, cadmium, lead, titanium.Zinc alloy fusing point is low, good fluidity, easy melting welding, and soldering and plastic working are corrosion-resistant in an atmosphere, and maimed material is convenient to reclaim and remelting; But creep strength is low, easily there is natural aging and cause dimensional change.Because zinc easily generates layer protecting film in surface at normal temperatures, therefore, the purposes that zinc is maximum is for zinc-plated industry.Zinc can and many non-ferrous metals formation alloy, wherein the alloy that forms of zinc and aluminium, copper etc., is widely used in die casting.

Summary of the invention

The technical problem to be solved in the present invention be to provide a kind of have good cooling, cleaning, lubrication, diffusion, high temperature resistant, thermal oxidation stability energy, can better keep the continuity of oil film and thickness, minimizing frictional coefficient and cold rolling time adherent phenomenon, zinc and the alloy foil cold-rolling lubricant thereof of plate shape and surface smoothness requirements can be met.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 5 industrial white oils, coordinate multiple composite additive, its each component and mass percent thereof are:

Non-emulsifying agent	0.2%～0.4%
		Friction improver	4.0%～5.0%

Base oil is No. 5 industrial white oils.

Anti-wear agent is boronation phosphamidon ester.

Oiliness improver is wind rapeseed oil.

Antioxidant preservative is sulphur phosphorus fourth octyl group zinc salt.

Oxidation inhibitor is alkyl diphenylamine.

Kilfoam is dimethyl silicone oil.

Non-emulsifying agent is polyethers macromolecular compound.

Friction improver is the phosphoric acid ester of mass ratio 40% ~ 50% and No. 75 Microcrystalline Wax compounds of 60% ~ 50%.

Zinc of the present invention and alloy foil cold-rolling lubricant thereof, adopt oil based on No. 5 industrial white oils, coordinate multiple composite additive, comprise anti-wear agent, oiliness improver, antioxidant preservative, kilfoam, non-emulsifying agent, friction improver.There is the performance that good cooling, cleaning, lubrication, diffusion, high temperature resistant, thermooxidizing are stable; Better can keep continuity and the thickness of certain oil film; Reduce frictional coefficient and cold rolling time roll and the adherent phenomenon of rolled piece, meet plate shape and surface smoothness requirements.
