Abstract

A grease lubricant for drawing aluminium wire contains basic oil CN150, other components, viscosity improver and filler, and serves to ensure high surface quality of drown aluminium wire and prevent rust and oxidation. It features no dry crack and no deterioration.

Description

Aluminium wiredrawing lubricating grease

The present invention relates to metal wire drawing lubricating composition.

Begin since fine aluminium is drawn aluminum steel as good conductor, people just seek good aluminum wire drawing lubricant, and by long-felt, generally generally acknowledged and employing locomotive oil is made aluminum wire drawing lubricant.The aluminium that also has some chemical enterprises to develop the different trades mark draws the lubricating oil supply the market, but the difficulty that all exists some to be difficult to overcome draws lubricant to exist not bright in vain, the sticking oil of wire surface many as locomotive oil as aluminium, and cleaning performance is poor, the sticking one deck aluminium powder in line surface causes easy oxidation and rusting; Pollute Working environment and drawing device, cause the field management difficulty big.Aluminium draws oil incompatibility diaphragm capsule formula drawing wire machine in use, occurs seepage easily and splashes, and the wire surface quality is brightless, sticking Chuck Steak, and most enterprises do not use.In sum, the still unresolved at present aluminum wire drawing lubricant gordian technique of China.

The object of the invention provides a kind of good aluminum wire drawing lubricant, solves aluminium backguy material surface quality, makes to pull out product line surface-brightening, not sticking oil or few sticking oil; Solve aluminium wire surface oxidation problem of rustiness simultaneously, make product line under acid air, saline alkali air ambient, keep 6 months non-corrosives; Also solve the diaphragm capsule formula lubricated in the oil seepage problem of splashing, reduce oil consumption, improve Working environment.

The present invention finishes with following mode: feature is that its chemical composition prescription is composed as follows by weight percentage:

SN150 base oil (base-material) 49.27～37.74;

Transformer oil 9.86～15.09;

Vegetable oil acid 9.86～11.32;

Stearic acid 7.39～7.55;

Molybdenumdisulphide 1.46～2.64;

Polyisobutene or other viscosity modifier 2.46～3.02;

Talcum powder or other filler 19.70～22.64.

The present invention has following advantage:

1. the storing keeping is put for a long time and never degenerated easily, and is not dry and cracked.

2. do not have in drawing and splash, Working environment is had clear improvement.

3. the wire surface quality improves, and the trace that do not raise track is not given birth to air marks, and is bright and clean bright in vain, not sticking oil, and no aluminium powder glues line.

4. oil consumption is economized, and the mould loss reduces, and the life-span prolongs 1.5 times.

5. the line surface forms anti-oxidant, the antiacid alkali environment of passive film after Passivation Treatment, and one-tenth dish pack-thread is in outdoor placement not blackening of non-corrosive more than six months.

Production craft step of the present invention is as follows:

A: processed

All water content materials are carried out processed

B: fat processing

To the mixing of heating of lipid article

C: viscosity adjustment

D: material homogenization treatment

E: discharging detects

Operation instruction of the present invention is as follows:

1. finished product is canescence semi-solid state shape, by wide-mouth plastic tank packing, gets material by diaphragm capsule volume equivalance when getting material and adds, and compacting is smooth;

2. before reinforced inlet wire, wire hole are blocked up with felt piece, reduce seepage;

3. install a clean line box and a passivation box additional at finished product die orifice leading-out terminal, make line behind this two box, reach the Cleaning and Passivation surface action.

4. the grease temperature rise should promptly be opened cooling system for 20-100 ℃ in the diaphragm capsule, keeps cooling good.

5. the grease of in time annotating keeps in the diaphragm capsule 4/5 fuel head often being arranged, and must guard against water droplet and enters in the diaphragm capsule in order to avoid cause broken string.

6. the periodic cleaning diaphragm capsule is removed the diaphragm capsule bottom and is contained the more grease of aluminium bits.

7. regularly change clothes line box felt, in time add passivating solution, keep liquid level in the passivation box.

The technology of the present invention parameter and application example:

1. technical parameter:

Appearance off-white semi-solid state paste

Burning-point is flammable in naked light

Viscosity is the thickness fraction in the time of 100 ℃

It is 7 100 ℃ the time that corrodibility does not have the corrosion pH value to aluminium

2. application example: test inlet wire φ 10mm outlet φ 3.07mm passage on No. seven aluminium-drawing machines of aerial condutor factory of lake cable group: 6 road backguys, 15 dishes amount to the inspection after constructions of the 600Kg left and right sides: the 1. pure white bright seamless no air marks of line surface light, rounding.2. expose 6 months non-corrosives in the outdoor acid air.3. 6 months lights of the placement of indoor paper pack are as new.
