Abstract

The invention relates to the field of ferrous metal and copper alloy sealing storage and corrosion prevention, and particularly relates to rust preventive oil and a preparation method thereof. The rust preventive oil consists of the following raw materials in parts by weight: 62-65 parts of kerosene, 5-6 parts of zinc naphthenate, 2-3 parts of triethoxyvinylsilane, 2-3 parts of dodecenylsuccinic acid, 3-5 parts of diethylene glycol monoethyl ether, 0.2 part of Vaseline and 0.2 part of 2,6 butylated hydroxytoluene. The rust preventive oil plays an outstanding rust preventing role in storage and has an excellent rust preventing effect on cast iron, copper and the like; a workpiece can be stored for over two years in sealing by corrosion prevention; more importantly, the rust preventive oil neither discolors easily nor oxidizes easily; in addition, sealing removal is simple and convenient, the sealed rust preventive oil can be wiped away just by means of wetting spun cotton with a little kerosene or gasoline, and the appearance of the workpiece is not affected; the rust preventive oil is excellent in comprehensive properties and strong in universality.

Description

A kind of slushing oil and preparation method

technical field

The present invention relates to the protection against corrosion field, particularly a kind of slushing oil and preparation method.

background technology

In the metal processing industry, due to workpiece from the blank to the finished product, a plurality of operations will be passed through in centre, because deposit is used or can't carry out the processing of next process in a short time, therefore will place it in warehouse and preserve, in library procedure, metal can because around different environment, being corroded more or less, can affect the characteristic of itself and hinder its following process or use after corrosion, the annual loss caused due to metallic corrosion is huge, and the meaning of protection is particularly important.

Long-term antirust for the stock, present common practice is coated slushing oil by workpiece surface exactly before the stock, existing soft film anti-rust oil that sell market, mainly by one or both inhibiter and membrane-forming agent and auxiliary agent, formed, moiety is more single, its single or certain specific several aspect excellent property, but over-all properties performance is not good enough, such as oil film time of drying after Corrosion Protection, salt spray corrosion resistance, water and sweat displacement performance, oiling, the thin and thick of filming, and oil film the general aspect such as can remove and can not take into account comprehensively.

Because Chinese Regional is vast, the weather kind of various places differs, the corrosion of metal environment is varied, even also there is different variations in the corrosive environment of areal, when needs metal stock is antirust, will according to different corrosive environments and different corrosion season careful select slushing oil used, time-consuming effort again, the versatility of slushing oil is very poor.

summary of the invention

In order to overcome the above problems; the invention provides a kind of formula and preparation method of comprehensive, soft film anti-rust oil with versatility; no matter extraneous corrosive environment is the corrosive environment of what type; also need not manage how the corrosive environment of areal Various Seasonal to change, protected metal works is had to good rustless property.

The present invention is achieved by the following measures:

A kind of slushing oil is comprised of the raw material of following weight proportion:

62 ~ 65 parts of kerosene,

5 ~ 6 parts of zinc naphthenates,

2 ~ 3 parts of vinyltriethoxysilanes,

2 ~ 3 parts of dodecenylsuccinic acids,

3 ~ 5 parts of diethylene glycol monoethyl ethers,

0.2 part, Vaseline,

2,6 0.2 part of ditertbutylparacresol.

Described kerosene is the 3# aviation kerosene.

Described zinc naphthenate zinc content is 5-7%.

The preparation method of described slushing oil:

(1) kerosene is added to the reactor heated and stirred, to 50-80 ℃;

(2) zinc naphthenate, vinyltriethoxysilane, dodecenylsuccinic acid and diethylene glycol monoethyl ether are added, be warming up to 120-130 ℃, fully stir until machinery oil fully dewaters;

(3) cool the temperature to 40-50 ℃, add Vaseline and 2,6 ditertbutylparacresols, elimination impurity gets final product to obtain slushing oil.

The invention has the beneficial effects as follows: slushing oil of the present invention is antirust particularly evident to the stock, for cast iron and copper etc., fabulous rust-proof effect is arranged, the anticorrosion time of sealing up for safekeeping of workpiece reached more than 2 years, the more important thing is, seal in process slushing oil up for safekeeping not easy to change, be difficult for oxidation, and go to seal up for safekeeping simple and convenient, be stained with a little kerosene or gasoline wipe sealed anti-rust oil with cotton yarn, do not affect the outward appearance of workpiece, high comprehensive performance; The highly versatile of slushing oil of the present invention.
