Description

Copper alloy cold rolling emulsified fluid composition

Technical field

The invention belongs to metal working lubricant field, particularly copper alloy cold rolling emulsified fluid composition.

Background technology

Copper is the non-ferrous metal very close with human relation, be widely used in electrically, light industry, machinofacture, building industry, the field such as national defense industry, in the consumption of China YouSe metallic substance, be only second to aluminium.Copper is most widely used in electric, electronic industry, consumption is maximum, accounts for aggregate consumption over half.For various cable and wire, motor and transformer, in the manufacture of switch and printed-wiring board (PWB).In machinery and carrier vehicle manufacture, for the manufacture of industrial valve and accessory, instrument, sliding surface bearing, mould, heat exchanger and pump etc.Be widely used in manufacturing vacuum, still pot, brew-kettle etc. in chemical industry.In order to manufacture bullet, shell, firearms part etc. in national defense industry.In building industry, be used as various pipeline, pipe fitting, trim component etc.

In the cold rolling industry of copper alloy, along with roll speed and rolled piece surface quality requirements improve constantly, also more and more higher to the requirement of milling train and Rolling Lubricant.Cold-rolling emulsion ubiquity poor stability, the lubricity of current use are not enough, the easy emulsified corrosion in rolled piece surface, the shortcomings such as clean annealing rear surface is of poor quality.Copper alloy cold-rolling emulsion has good adhesivity, resistance to abrasion, shear resistant and emulsifying stability are good, extreme pressure property is strong, oil film thickness stability, cooling, mobility, wetting property and oilness, oil film strength is large, there is less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability, ensure to use and easy to clean, have the ability preventing rust staining and surface imperfection.

Summary of the invention

The technical problem to be solved in the present invention is to provide one and has good adhesivity, resistance to abrasion, shear resistant and emulsifying stability are good, extreme pressure property is strong, oil film thickness stability, cooling, mobility, wetting property and oilness, oil film strength is large, there is less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability, ensure to use and easy to clean, have the copper alloy cold rolling emulsified fluid composition of the ability preventing rust staining and surface imperfection.

Copper alloy cold rolling emulsified fluid composition, adopt oil based on No. 10 total loss system oil, coordinate multiple additives, its each component and mass percent thereof are:

		Corrosion inhibitor	0.5％～1％
Kilfoam	50ppm～100ppm
		Auxiliary agent	3.0％～4.0％
Strengthening agent	1.0％～1.5％

Emulsifying agent is the NPE50 compound of the OPE-10 and 50% of mass ratio 50%.

Oxidation inhibitor is 2,6-di-t-butyl mixed phenol T502.

Oiliness improver is the soybean oil of mass ratio 50% and the butyl oleate compound of 50%;

Extreme pressure agent is sulfuration Oleum Gossypii semen.

Anti-wear agent is single sulfuration normal-butyl phosphoric acid ester T311.

Corrosion inhibitor is the lanolin compound of the benzotriazole T706 and 50% of mass ratio 50%.

Kilfoam is dimethyl silicone oil.

Auxiliary agent is phosphoric acid ester.

Strengthening agent is petroleum sodium sulfonate T702.

Remarkable advantage of the present invention is: have good adhesivity, resistance to abrasion, shear resistant and emulsifying stability are good, extreme pressure property is strong, oil film thickness stability, cooling, mobility, wetting property and oilness, oil film strength is large, there is less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability, ensure to use and easy to clean, have the ability preventing rust staining and surface imperfection.
