Abstract

The invention discloses an aluminum and aluminum alloy hot-rolled ionic emulsion composition. The 5# total-loss system oil is used as the base oil which is compounded with multiple additives such as an antiwear agent, an oiliness agent, an antioxidant preservative, a bactericide, an emulsifier, a metal deactivator and a coupling agent. The aluminum plate hot-rolled ionic emulsion has the advantages of good cooling and lubricating property, proper thermal decomposability, good aluminum powder separation ability, long service cycle, convenience in maintenance and management and the like, and is corrosion-free, odorless and non-toxic to a roller and related equipment.

Description

Al and Alalloy material hot rolling ionic microemulsion formulations

Technical field

The invention belongs to hot rolling aluminium technology lubricant, especially Al and Alalloy material hot rolling ionic microemulsion formulations.

Background technology

In metal-working industry, hot rolling is often referred to the operation of rolling that metal carries out more than recrystallization temperature.In the hot rolling, there are sclerosis and softening two processes in deformable metal simultaneously.It is generally acknowledged that course of hot rolling metal does not have work hardening, plasticity is higher, and distortion resistivity is lower, can obtain larger viscous deformation with less energy; Therefore, most metals all adopts hot rolling.

In existing non-ferrous metal, the large and mainly Al and Alalloy that use range is wider of consumption.When rolling aluminum and aluminium alloy material, rolling temperature is between 350 ~ 520 DEG C.Due in the operation of rolling, aluminium particulate shifts from rolled piece to roller surface, metallic aluminium bits and lubricating oil generation chemical reaction, forms the fine and closely woven aluminium powder of one deck, the oxide compound of aluminium and the sticky aluminium lamination of some oiliness improvers composition at roller surface.If lubricant quality is better, sticky aluminium lamination is just thinner.But, even if sticky aluminium lamination is very thin, can not ensure that the sticky aluminium of roller surface does not affect rolled piece surface quality.Therefore, as the technique lubrication prescription of Al and Alalloy material hot rolling, except cooling, lubrication should be had and reduce except roll wear effect, also must effectively reduce or prevent roll from gluing aluminium, ensure hot rolling blank surface quality, prevent the phenomenons such as collaring.And often in this, as one of important symbol evaluating rolling aluminum and aluminium alloy material technology lubricant.Therefore, the emulsion allocated by mineral oil and compound multiple additives and water, one of primary lubricant agent just becoming rolling aluminum and aluminium alloy material technique.

When rolling aluminum and aluminium alloy material, usually to spray a large amount of emulsion to prevent roll overheated and to bond with aluminium.Gathering for preventing the aluminium powder generated in the operation of rolling, sticking on roll, affect the quality of stocking, to require on all surfaces that emulsion can make aluminium powder be diffused into rapidly roll and can wash out at any time; Meanwhile, the emulsion of hot rolling aluminium also requires good emulsifying stability and thermostability; Also must there be suitable frictional coefficient and good lubricity.Because applying working condition is different with the water quality in region, in the O/W type emulsion that hot rolling aluminium adopts, be divided into ionic, non-ionic type and compound three types.The feature of ionic emulsion is: oilness, cooling performance are good, and cost is low, prepares easy, is easy to a large amount of use, and breakdown of emulsion is easy, convenient post-treatment, but more perishable and produce corrodibility.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of oilness and cooling performance is good, and cost is low, prepares easy, and breakdown of emulsion is easy, the Al and Alalloy material hot rolling ionic microemulsion formulations of convenient post-treatment.

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

Component	Content (mass percent)
		Base oil	55%～70%
