Abstract
The invention relates to an aircraft aluminum alloy plate strip hot-rolling lubricant which is prepared by adopting hydrogenated light component oil as base oil and compounding and mixing the hydrogenated light component oil with a plurality of additives. The additives include an anti-wear agent, an oil-based agent, an antioxidant, an anti-foaming agent, an antiseptic agent, an emulsifying agent, a coupling agent, a metal deactivating agent, a corrosion inhibitor and the like. The lubricant is low in viscosity, thereby quickening the cooling process; the oxidization stability is excellent, and the friction is proper; contamination does not exist in annealing; the aircraft aluminum alloy plate strip hot-rolling lubricant is high in flash point, low in final distillation point, and narrow in distillation range; the aircraft aluminum alloy plate strip hot-rolling lubricant is excellent in polishing action, thereby keeping high finishing degree; the aircraft aluminum alloy plate strip hot-rolling lubricant has less possibility of being adhered to a roll and can be easily filtered.
Description
Technical field
The invention belongs to aviation-grade aluminium alloy thick plate hot-rolled lubricant field.
Background technology
Aluminium alloy thick plate is the important structured material of modern aerospace industries, and current developed country aluminum i ndustry circle continually develops out the novel aluminum alloy slab of excellent performance, is widely used in aircraft ring frames, integral panel, landing gear, covering etc.They have high strength, good toughness, resistance to stress performance and antistripping corrosive nature, and fracture toughness property is better, and fatigue crack extended capability is strong, and aluminium alloy thick plate has good over-all properties as space flight and aviation material.
Aluminium alloy thick plate has a lot of sorting technique, have to divide by purposes, have to divide by thickness, has to divide by state.Divide by purposes, aviation-grade and non-aviation-grade can be divided into.The former is for the manufacture of spacecraft, and latter is for other department.Aviation-grade aluminium alloy thick plate more than 96% uses heat-treatable strengthened aluminum alloy rolling.Aviation-grade aluminium alloy thick plate has about 90% aluminium alloy material strengthened for thermal treatment.Their purposes widely, almost for each department of national economy.During the hot rolling of aviation-grade aluminium alloy thick plate, need to spray a large amount of emulsion to prevent from boning with aluminium because roll is overheated.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of viscosity is lower, excellent oxidation stability, frictional force suitably, annealing time do not form stains, high flash point, low final boiling point, narrow boiling range, good, the sticky roll of polishing action and the aviation-grade aluminium alloy thick plate hot-rolled lubricant easily filtered.
