Abstract
The invention discloses a lubricant for cold rolling of cobalt and alloy foils thereof. Poly-alpha-olefin is adopted to be compounded with poly-internal-olefin as base oil, and matched with a plurality of composite additives comprising an antiwear agent, an oiliness agent, an anti-foaming agent, an antioxidant, an anti-creaming agent, an extreme pressure agent and a friction modifier. The lubricant for cold rolling of cobalt foils is short in carbon chain, low in aromatic hydrocarbon, low in sulphur content, low in viscosity, large in heat capacity, and strong in cooling and cleaning abilities, and is stable in constituent and performance, and free of corrosion on metal and equipment, free of toxicity, and free of a pungent smell, meanwhile, the processing lubrication performance is improved, the strength of an oil slick inside a deformation zone is increased, the friction coefficient is reduced, and adhesion of a rolled piece and a roller is reduced.
Description
Technical field
The invention belongs to cobalt and alloy foil cold-rolling lubricant field thereof.
Background technology
The physics of cobalt, chemical property have determined that it is the important source material of producing refractory alloy, Wimet, anti-corrosion alloy, magneticalloy and various cobalt salts.Cobalt base alloy or cobalt-containing alloy steel are as the heat-resistant part of various high loadinies and the important meals material of nuclear industry in the parts of the blade of gas turbine, impeller, conduit, jet engine, rocket engine, guided missile and chemical industry equipment.Cobalt can guarantee that as the binding agent in powder metallurgy Wimet has certain toughness.Magneticalloy is indispensable material in Modern Electronic and mechanotronics, is used for the various elements of the equipment such as manufacture sound, optical, electrical and magnetic.
Cobalt metal is mainly used in producing alloy.Cobalt base alloy is the general name of one or more alloys made in cobalt and chromium, tungsten, iron, nickel group.Containing a certain amount of Cutlery Steel of cobalt, can improve significantly wear resistance and the cutting ability of steel.Even be heated to 1000 ℃ containing more than 50% stellite of cobalt, also can not lose its original hardness, nowadays this Wimet has become the most important material of alloy cutting tool and space application.In this material, cobalt combines other metallic carbide crystal grain in alloy composition, makes the toughness that alloy tool is higher, and reduces the sensitive property of impact, and this alloy is welding in piece surface, can make the life-span of part improve 3-7 doubly.By cold rolling to cobalt and alloy foil finished product thereof, can obtain the good shape material of surface quality.
Summary of the invention
It is short that the technical problem to be solved in the present invention is to provide a kind of carbochain, low aromatic hydrocarbons, low sulfur content, and viscosity is lower, and thermal capacitance is large, cooling, cleansing power is strong; Also there is the technological lubrication of raising performance simultaneously, increase oil film strength in distorted area, reduce frictional coefficient; Form and stable performance; Corrosion-free to metal and equipment; Reduce the adhesion of rolled piece and roll; Nontoxicity, the cobalt having no irritating odor and alloy foil cold-rolling lubricant thereof.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt Poly alpha Olefins (PAO) and poly-internal olefin compound as base oil, coordinate multiple composite additive, its each component and mass percent thereof are:
