Abstract

The invention discloses a cold-rolling lubricant for cadmium and alloy foil materials thereof. According to the cold-rolling lubricant, 7# industrial white oil adopted as base oil is compounded with various composite additives including an anti-wear agent, an oiliness agent, an anti-oxidant preservative, an anti-oxidant, an anti-forming agent, a metal deactivator, and the like. The cold-rolling lubricant disclosed by the invention has lower viscosity, greater heat capacity and strong cooling and cleaning capability, can be used for reducing an adhesion phenomenon of a rolling piece and a rolling roller; meanwhile, the cold-rolling lubricant further can be used for improving the process lubricating performance, increasing the oil film strength in a deformation zone and lowering the friction coefficient, and is stable in composition and performance, free from corrosion to metals and equipment, non-toxic and free from pungent smell.

Description

Cadmium and alloy foil cold-rolling lubricant thereof

Technical field

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

Background technology

Cadmium is the glossiness metal of silvery white, fusing point 320.9 DEG C, boiling point 765 DEG C, density 8650kg/m3.Flexible and ductility.Cadmium slow oxidation lose metalluster in damp atmosphere, during heating, surface forms brown oxide skin.Cadmium is mainly used in the plating of steel, iron, copper, brass and other metals, strong to the anti-corrosion capability of alkaline matter.Cadmium can be used for manufacturing the battery that volume is little and electrical capacity is large.The compound of cadmium is also a large amount of for the production of pigment and fluorescent material.It is a kind of superior metal absorbing neutron, makes rod and can slow down nucleon chain reaction speed in atomic reactor, and rather useful in zinc-cadmium cell.

For the manufacture of alloy: cadmium, as alloy compositions element, can be made into a lot of alloy, as the hard copper alloy containing cadmium 0.5% ~ 1.0%, there are higher tensile strength and wear resistance.Cadmium (98.65%) nickel (1.35%) alloy is the bearing materials of aircraft engine.Containing cadmium in a lot of low melting point alloy, in famous wood's alloy, reach 12.5% containing cadmium.Cadmium has larger thermal-neutron capture cross-section, and therefore the alloy of argentiferous (80%) indium (15%) cadmium (5%) can make (neutron-absorbing) control rod of reactor.The compound of cadmium was once widely used in manufacture (yellow) pigment, stabilizer for plastics, (video mapping pipe) fluorescent material, sterilant, sterilant, paint etc.For plating etc.: cadmium oxidizing potential is high, therefore can be used as the protective membrane of iron, steel, copper, is widely used on electroplating anticorrosion, but because of its toxicity large, this purposes has reduces trend.For rechargeable battery: ni-cd and silver-cadmium cell have the advantages such as volume is little, capacity is large.

Summary of the invention

It is lower that the technical problem to be solved in the present invention is to provide a kind of viscosity, and thermal capacitance is large, cooling, cleansing power are strong, can reduce the adherent phenomenon of rolled piece and roll, can also improve technological lubrication performance simultaneously, increase oil film strength in distorted area, reduction frictional coefficient; Composition and stable performance; To metal and equipment corrosion-free; Nontoxicity, the cadmium had no irritating odor and alloy foil cold-rolling lubricant thereof.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 7 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	3.0%～4.0%
		Oiliness improver	3.0%～5.0%

		Oxidation inhibitor	0.3%～0.5%
Kilfoam	0.001%～0.005%
		Non-emulsifying agent	0.2%～0.5%
Friction improver	10.0%～15.0%

Base oil is No. 7 industrial white oils.

Anti-wear agent is boronation phosphamidon ester.

Oiliness improver is hydrogenated castor oil.

Antioxidant preservative is sulphur phosphorus Zhong Ji zinc salt.

Oxidation inhibitor is thiadiazoles derivative.

Kilfoam is dimethyl silicone oil.

Non-emulsifying agent is polyethers macromolecular compound.

Friction improver is mass ratio 30% ~ 35%.Phosphoric acid ester, No. 75 Microcrystalline Waxes of 30% ~ 35% and the whiteruss compound of 40% ~ 30%.

Cadmium of the present invention and alloy foil cold-rolling lubricant thereof, adopt oil based on No. 7 industrial white oils, coordinate multiple composite additive, comprise anti-wear agent, oiliness improver, antioxidant preservative, oxidation inhibitor, kilfoam, metal passivator etc.This cold-rolling lubricant viscosity is lower, and thermal capacitance is large, cooling, cleansing power are strong, can reduce the adherent phenomenon of rolled piece and roll; Technological lubrication performance can also be improved simultaneously, increase oil film strength in distorted area, reduce frictional coefficient; Composition and stable performance; To metal and equipment corrosion-free; Nontoxicity, has no irritating odor.
