CN104164285A - No-clean punching oil - Google Patents

Abstract

The invention provides a no-clean punching oil, which is prepared from the following components in percentage by mass: 80-90% of C13-C16 alkanes, 1-5% of Span-80, 0.2-0.6% of GY-10, and 6-15% of tall oil. The no-clean punching oil is fast in volatility, the surface of a punched workpiece is dry and clean, and free from cleaning, and does not contain substances such as chlorine, sulfur, silicon, the no-clean punching oil has an antirust function, and is simple in production technology, low in cost, non-corrosive and odorless.

Description

One exempts to clean punching oil

technical field:

The present invention relates to a kind of punching oil, relate in particular to one and exempt to clean punching oil.

background technology:

At present, the punching press of aluminium fin both at home and abroad, all adopts the low-density oil solvent that contains a small amount of aromatic hydrocarbon conventionally, has certain smell, contaminate environment with this low-density oil solvent that contains aromatic hydrocarbon.And in this punching oil product, mostly contain chlorine, sulphur, silicon etc., to human body and the harmful composition of environment, and utilize existing punching oil not have antirust function, for the stamping parts product easily getting rusty containing iron and steel composition, Yin Qiyi gets rusty and is difficult for preserving.How with one be beneficial to environmental protection, lubricity is good, punching oil stamping parts to antirust function is used as substitute, becomes the major issue that domestic and international punching press industry is paid close attention to.

summary of the invention:

The open one of the present invention exempts to clean punching oil, has quick volatility fast, and the surface dry of stamped workpieces does not need to clean, and the materials such as not chloride, sulphur, silicon, have antirust function, and manufacture craft is simple, and cost is low, non-corrosiveness, odorlessness.

One of the present invention exempts to clean punching oil, is made up of than component following quality:

C ₁₃-C ₁₆alkanes 80-90%,

Span-80 1-5%，

GY-10 0.2-0.6%，

Yatall MA 6-15%.

One of the present invention exempts to clean punching oil, is preferably made up of than component following quality:

C ₁₃-C ₁₆alkanes 86.5%,

Span-80 3%，

GY-10 0.5%，

Yatall MA 10%.

Component S pan-80 of the present invention is Sorbitol Powder fatty acid ester or sorbitan oleate;

GY-10 is the esters polymer of high molecular.

Preparation method of the present invention is: in reaction unit, the bottom installation outlet valve of device, under normal temperature, normal pressure, by the feed composition C of aforementioned proportion ₁₃-C ₁₆alkanes, Span-80, GY-10, Yatall MA drop in the reaction unit mixing kettle of bottom mounted valve outlet with pump respectively, and with mixing pump circulation stirring, after 15-20 minute, then leaving standstill 10-15 minutes can fillingly be product of the present invention.

The present invention compared with prior art tool has the following advantages and positively effect:

Have quick volatility, especially, under heating condition, workpiece surface is dry and comfortable, does not need to clean, and reduces production costs;

There is good extreme boundary lubrication, can extend die life, ensure the good processing quality of workpiece surface;

Stamping parts is had to antirust function, be convenient to the short-term storage of workpiece; The punching oil product flash-point of producing is high, smell and light; Viscosity pole is low, and cooling is good; Not chloride, sulphur, silicon, to human body and environmentally friendly.Product stability is good.

Stability of the present invention: referring to that composition prepared by the present invention was placed after 4-6 hour observes solution layering situation; Stabilize to not stratified, not muddyly, shakiness is decided to be layering or muddiness.

Product clean-out system of the present invention detects all technical through Institute of Analysis of Jiangxi Province and all reaches requirement;

Test atmosphere condition: temperature: 20 DEG C, humidity: 55%,

Sample situation: sampling, liquid,

Test basis: SH/T 0692-2000 standard etc.,

Testing instruments: automatical potentiometric titrimeter etc.;

Assay is as following table 1.

Table 1, technical target of the product:

Illustrate: 1, the corrodibility (40 DEG C ± 2 DEG C) in the present invention's product, 45 ﹟ steel discs, 0 grade of 4h,

Duralumin LY12,0 grade of 2h,

Brass H62,0 grade of 2h;

2, volatility is good when product punching press of the present invention, and the shelf time is long.

embodiment:below in conjunction with specific embodiment, the invention will be further described.

embodimentas follows:

Illustrate: each component of the present invention all can be by commercially available acquisition.

The above-described each embodiment of the present invention is all prepared by following method:

Carry out as follows: in reaction unit, in the bottom installation outlet valve of device, under normal temperature, normal pressure, by the feed composition C of aforementioned proportion ₁₃-C ₁₆alkanes, Span-80, GY-10, Yatall MA drop in the reaction unit mixing kettle of bottom mounted valve outlet with pump respectively, and with mixing pump circulation stirring, after 15-20 minute, then leaving standstill 10-15 minutes can fillingly be product of the present invention.
