A kind of Drawing Lubricant for High Speed Aluminium Rod Drawing Machine of low-friction coefficient
Technical field
The present invention relates to a kind of wire drawing oil, be specifically related to a kind of Drawing Lubricant for High Speed Aluminium Rod Drawing Machine and preparation technology thereof of low-friction coefficient.
Background technology
Wire drawing oil is the important industrial auxiliary agent of a class, in wire drawing, drawing process process, does efficient lubricant oil use, has lubricated, cleaning, the effect such as cooling, antirust, assists metal flow, avoids mould to drag colored bracing wire, improves yield rate, reduces production loss. Existing wire drawing oil is mainly divided into oiliness wire drawing oil and water-based wire drawing oil, this two classes wire drawing oil cuts both ways in the time that reality is used, as oiliness wire drawing oil exists heat dispersion poor, cleaning chip removal difficulty, the problems such as waste liquid difficult degradation, and although the wire drawing oil heat dispersion of water-based is good compared with oiliness wire drawing oil, but lubricant effect is not fully up to expectations, the wire drawing that is difficult to meet various metals line is drawn and is dialled technological requirement, therefore for improve enterprise machined level, reduce production costs, need to improve wire drawing oil formula and technique, make it reach good serviceability.
Summary of the invention
The object of the invention is to, a kind of Drawing Lubricant for High Speed Aluminium Rod Drawing Machine of low-friction coefficient is provided, to reach good wire-drawing effect, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of Drawing Lubricant for High Speed Aluminium Rod Drawing Machine of low-friction coefficient, it is characterized in that, material of the present invention is made up of the raw material of following weight portion: sulfonated oil 10-12, silicone emulsion 50-60, polyvinyl acetate 2-3, calgon 0.5-1, ethoxylated dodecyl alcohol 4-5, perfluoro polyether oil 100-120, triethanolamine borate 1-2, propane diols phenylate 0.5-1, calcium sulfonate with high base number 1-2, auxiliary agent 2-3; Described auxiliary agent is made up of the raw material of following weight portion: Graphene 1-2, silane coupler KH5600.1-0.2, isostearic acid 15-18, xanthans 10-12, sorbester p17 4-5, deionized water are appropriate; Preparation method is: first by Graphene and silane coupler mixed grinding 10-15min, the powder obtaining mixes with isostearic acid, sorbester p17, under the rotating speed of 1000-1500 rev/min, stir 20-30min, make emulsion for subsequent use, then xanthans is mixed with appropriate deionized water, be mixed with the xanthan gum solution that mass concentration is 60-70%, finally the aqueous solution, emulsion are mixed, continue to stir 15-20min with 1000-1500 rev/min of rotating speed, stir and finish rear standing 2-4h, to obtain final product.
The Drawing Lubricant for High Speed Aluminium Rod Drawing Machine of described a kind of low-friction coefficient, its preparation technology is:
(1) first sulfonated oil, calgon are mixed, stir 15-20min, mixed liquor is for subsequent use;
(2) perfluoro polyether oil is heated to 50-60 DEG C, adds step (1) gained material and ethoxylated dodecyl alcohol, fully mix and blend 30-35min, add again subsequently other leftover materials, continue to stir 50-60min, after stirring finishes, through naturally cooling to room temperature, get product.
The wire drawing oil that the present invention prepares, using perfluoro polyether oil as base oil, there is good lubricity and oxidation stability, but perfluoro polyether oil in use cost is higher, density is large, in order to reduce production costs, in formula, add the silicone emulsion with good lubricated and heat resistance, make it still retain good lubricity and heat resistance, again in conjunction with other additive, wire drawing oil viscosity prepared by the present invention is moderate, heat-resisting stable, easily and aluminum steel surface filming, and oil film can the attenuation along with the rising of temperature, low with the coefficient of friction of mould and wire surface, in protection mould, also reach good wire-drawing effect, the aluminium wire surface-brightening no marking of pull-out, energy consumption is low, be particularly suitable for aluminium wire and draw greatly at a high speed use.
Detailed description of the invention
Embodiment
The present embodiment wire drawing oil by following weight portion (kilogram) raw material make: sulfonated oil 12, silicone emulsion 50, polyvinyl acetate 3, calgon 0.5, ethoxylated dodecyl alcohol 5, perfluoro polyether oil 120, triethanolamine borate 2, propane diols phenylate 0.5, calcium sulfonate with high base number 2, auxiliary agent 3; Described auxiliary agent is made up of the raw material of following weight portion: Graphene 1, silane coupler KH5600.2, isostearic acid 15, xanthans 10, sorbester p17 4, deionized water are appropriate; Preparation method is: first by Graphene and silane coupler mixed grinding 15min, the powder obtaining mixes with isostearic acid, sorbester p17, under the rotating speed of 1500 revs/min, stir 20min, make emulsion for subsequent use, then xanthans is mixed with appropriate deionized water, be mixed with mass concentration and be 60% xanthan gum solution, finally the aqueous solution, emulsion are mixed, continue to stir 15min with 1500 revs/min of rotating speeds, stir and finish rear standing 2h, to obtain final product.
The Drawing Lubricant for High Speed Aluminium Rod Drawing Machine of described a kind of low-friction coefficient, its preparation technology is:
(1) first sulfonated oil, calgon are mixed, stir 20min, mixed liquor is for subsequent use;
(2) perfluoro polyether oil is heated to 50-60 DEG C, adds step (1) gained material and ethoxylated dodecyl alcohol, fully mix and blend 35min, add again subsequently other leftover materials, continue to stir 60min, after stirring finishes, through naturally cooling to room temperature, get product.
