Abstract
Compositions related to a water-based lubricant fluid for aluminum cold rolling which is free from measurable particles or oil droplets which can be applied in field production. A single-phase lubricant fluid may include water-soluble polymers, lubricating additives, anti-rust additives, anti-oxidant additives, pH-adjust additives, or combinations thereof.
Description
Background of invention
Aluminium is cold rolling to be one of most important technology of aluminium application.Lubricant is very crucial for continuous production and good quality.Traditionally, mainly contain two classes be used for cold-rolling process lubricating method: 1) lubricate with pure oil and 2) lubricate with O/w emulsion.First-generation lubricant is pure oil.Pure oil production provides good plate surface quality, but also has major defect: 1) inflammable; With 2) higher wear rate.S-generation product is the O/w emulsion product.With pure oil phase ratio, emulsion has been avoided the problem of using pure oil production to bring.The potential shortcoming of emulsion comprises: 1) since too high vaporization temperature cause annealing after the degree of cleaning of band limited; With 2) the easy emulsification of sump oil, this has reduced rolling performance.
Embodiments more of the present invention be used for the shortcoming that the cold rolling aqueous solution lubricant of aluminium has solved conventional lubrication.
US4,828,737 disclose the application of aqueous product in aluminium is cold rolling.Yet according to this patent, these aqueous products need reach 360 ℃ temperature just evaporation afterwards.Aqueous solution lubricant in embodiment of the present invention can allow all processing condition that apply when aluminium alloy (part) annealed thus 240 ℃ of evaporations fully.
Summary of the invention
According to some embodiments, be used for the cold rolling lubricant fluid of aluminium and comprise the single-phase water based sols with water-soluble polymers.In some embodiments, this polymkeric substance comprises at least a hydrophilic radical, as oxyethane (ethylene oxide).In some embodiments, the molecular weight of this polymkeric substance is about 200 or bigger.In certain embodiments, this lubricant fluid comprises the water-soluble polymers of the about 99wt% of about 5wt%-.In some embodiments, this lubricant fluid comprises at least a lubricant additive, and it can be water miscible.In some embodiments, this lubricant additive package is drawn together one or more carbon-chain structures, one or more hydrophilic radicals or its combination.Lubricant fluid can comprise the lubricant additive of the about 10.0wt% of about 0.1wt%-.In certain embodiments, this lubricant fluid comprises at least a functional additive for example rust-inhibiting additive, anti-oxidant additives, pH regulator additive or its combination.This lubricant fluid can comprise the functional additive of the about 5wt% of about 0.05wt%-.

Fig. 3 has shown the rolled strip that uses prescription of the present invention.
Embodiment
The composition of some embodiments of the present invention and method relate to the aluminium cold-rolling process that uses single-phase water base lubricating agent fluid.The compositions and methods of the invention can comprise for the cold rolling water base lubricant fluid of aluminium, and it does not contain or is substantially free of measurable particle or oil droplet.In some embodiments, lubricant fluid comprises one or more water-soluble polymerss.Lubricant fluid can also comprise one or more lubricant additive and various functional additive.
Traditionally, O/w emulsion is administered on the band in the aluminium cold-rolled process.But, use O/w emulsion to have shortcoming, for example cause the discordance on shredder, high oil consumption etc. in band degree of cleaning limited after the annealing, not enough filterableness, the emulsion characteristic of fluctuation.In some embodiments, such shortcoming can be avoided according to the single-phase water base lubricating agent fluid of embodiments more of the present invention by using.Single-phase water base lubricating agent fluid according to embodiments more of the present invention can be used for the aluminium of any kind and the cold rolling application of alloy.
According to traditional cold rolling lubrication theory and industry experience, in rolling technology, there are two kinds of lubricating status (regime): boundary lubrication and elastohydrodynamic lubrication (" EHD ").Many aluminium rolling technologys can carry out with mixed lubricating state, comprise that boundary lubrication and EHD lubricate the characteristic of the two.So in some embodiments, lubricant fluid of the present invention can provide lubricated-boundary lubrication and/or elastohydrodynamic lubrication.Because the aluminium deformation stress lubricates and tends to boundary lubrication.In some embodiments, lubricant fluid of the present invention can provide following characteristic: 1) the surface of good quality is provided, does not have the dirty marking of tangible water; 2) do not show residually on aluminium sheet after the annealing, wherein whole materials all should be eliminated before 240 ℃; With 3) repel sump oil, it should be easy to and solution separating.
So in some embodiments of the present invention, single-phase water base lubricating agent fluid can provide the lubricity that enough is used for the boundary lubrication of cold-rolling process.
