Abstract

The invention relates to an additive, specifically relates to an additive added to a cooling liquid to improve the properties of the cooling liquid, and more specifically relates to an antirust agent and a preparation method thereof. The antirust agent is prepared by virtue of the following steps: heating dechlorinated tap water, triethanolamine and diethanol amine together to 70 DEG C to obtain a solution a, cooling the solution a to 40 DEG C, adding polyethylene glycol, stirring for 15 minutes to obtain a solution b, heating the solution b to 45 DEG C, adding sorbitol, stirring for 20 minutes to obtain solution c, heating the solution c to 50 DEG C, adding sorbitol, and mixing and stirring until the sorbitol is dissolved and the solution is transparent. The prepared antirust agent is added to the cooling liquid and capable of functioning in lubricating and preventing rust in the cutting process; the preparation method is simple; and the prepared antirust is a non-toxic compound without toxicity and harm, and is non-toxic and unharmful to a human body, good in rust prevention property and non-corrosion to a cut piece.

Description

A kind of rust-preventive agent and preparation method thereof

Technical field

The present invention relates to a kind of additive, be specifically related to a kind ofly be added on a kind of additive that cooling fluid increases cooling fluid performance, relate to a kind of rust-preventive agent and preparation method thereof specifically.

Background technology

Metal processing piece is in the process of process for processing and transport, be easy to get rusty, this just needs to use slushing oil to form thin film in metallic surface, prevent the chemical of corrosion of metal, so-called rust is because oxygen and water act on the mixture that metallic surface generates oxide compound and oxyhydroxide, iron rust is red, patina is green, and the rust of aluminum and zinc claims white rust, machinery operation and storage in be difficult to not with the oxygen in air, moisture or the contact of other corrosive medium, generation galvanic corrosion is got rusty in metallic surface by these materials, prevent corrosion from must stop above material and metallic contact, rust-preventive agent belongs to the one of antirust product, the slushing oil in addition of other type, anti-tarnish paper etc., rust-preventive agent is a kind of synthesis permeate agent of super grade high efficiency, it powerfully can infiltrate iron rust, erosion, dispose screw like a cork in greasy dirt, rusty stain on nut and erosion, there is infiltration rust cleaning, loosen lubrication, resist corrosion, the performances such as protection metal.And can be formed on parts surface and store one deck lubricant film, the corrosion that moisture and other Chemical Composition many cause can be suppressed, cooling fluid of the prior art also exists unstable properties, not easily preservation, and these rust-preventive agent are serving harm to environment band in various degree.

Summary of the invention

Object of the present invention is added in cooling fluid providing one, a kind of rust-preventive agent preventing cut part from getting rusty and preparation method thereof.

The technical solution used in the present invention is:

A kind of rust-preventive agent, it is made up of 20%-30% dechlorination tap water, 20%-30% trolamine, 12%-20% diethanolamine, 15%-20% polyoxyethylene glycol, 28.5%-35% sorbyl alcohol, 2.8%-5% benzotriazole;

A preparation method for rust-preventive agent, it is made up of following steps:

(1) in above ratio part remove chlorine tap water, trolamine, diethanolamine merge be heated to 70 DEG C solution a;

(2) solution a is cooled to 40 DEG C, adds polyoxyethylene glycol, stir 15 minutes, obtain solution b;

(3) solution b is heated to 45 DEG C, adds sorbyl alcohol, stir 20 minutes, obtain solution c;

(4) solution c is heated to 50 DEG C, adds sorbyl alcohol, mix to dissolving transparent.

The rust-preventive agent that the present invention prepares, it is for adding in cooling fluid, lubrication and antirust function can be played in cutting process, its preparation method is simple, the rust-preventive agent prepared belongs to non-toxic type compound, toxicological harmless, to the effect of human non-toxic's evil, good antirust property, and corrosion can not be caused to cut part.
