Description

A kind of wire drawing oil containing nanometer silver

Technical field

The present invention relates to a kind of wire drawing oil, be specifically related to a kind of wire drawing oil and preparation technology thereof containing nanometer silver.

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 processing requirement, therefore for improve enterprise machining level, reduce production costs, need to improve wire drawing oil formula and technique, make it reach good use properties.

Summary of the invention

The object of the invention is to, a kind of wire drawing oil containing nanometer silver is provided, reach the wear-resistant effect of rubbing of falling, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of wire drawing oil containing nanometer silver, it is characterized in that, material of the present invention is made up of the raw material of following weight part: Yatall MA 2-3, Oleum Gossypii semen 70-90, mineral oil 70-80, trolamine boric acid ester 5-6, xylitan monostearate 1-2, polyvinylpyrrolidone 1-2, nanometer silver 1-2, butylated hydroxytoluene 1-2, deionized water 4-5, auxiliary agent 2-3; Described auxiliary agent is made up of the raw material of following weight part: Graphene 1-2, silane coupling agent KH560 0.1-0.2, Unimac 5680 15-18, xanthan gum 10-12, sorbester p17 4-5, deionized water are appropriate; Preparation method is: first by Graphene and silane coupling agent mixed grinding 10-15min, the powder obtaining mixes with Unimac 5680, sorbester p17, under the rotating speed of 1000-1500 rev/min, stir 20-30min, make emulsion for subsequent use, then xanthan gum 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.

Described a kind of wire drawing oil containing nanometer silver, its preparation technology is:

(1) first nanometer silver is mixed with deionized water, be stirred well to nano silver powder and disperse completely in water, add subsequently polyvinylpyrrolidone, fully stir 20-30min, mixed solution is for subsequent use;

(2) by Oleum Gossypii semen, mineral oil, be heated to 50-60 DEG C, add Yatall MA, xylitan monostearate, stir after 20-30min, add again step (1) gained mixture and other leftover materials, continue to stir 40-50min, after stirring finishes, through naturally cooling to room temperature, get product.

The advantage of the more traditional wire drawing oil of wire drawing oil that the present invention prepares is: added especially the nano silver powder through surface modification treatment, the Nano silver solution making can be in base oil good distribution, these nano-silver powders that are scattered in lubricating oil can form low shearing film with metal wire and die surface, can effectively reduce skin friction coefficient, reduce production energy consumption, nanometer silver also has good antibacterial preservative activity simultaneously, extends the work-ing life of wire drawing oil; Contain in addition that some are anti-oxidant, the additive of antirust class, make wire drawing oil of the present invention have good over-all properties, more highly effective, can meet wire drawing, the drawing process demand of various metals material.
