CN102218530A - Special anti-rust oil for iron powder stamping part - Google Patents

Abstract

The invention provides special anti-rust oil for iron powder stamping part, which comprises components with weight percent as follows: 1-2 percent of oleic acid, 4-9 percent of triethanolamine, 3-7 percent of sodium alkylsulfonate, 3-7 percent of dinonylnaphthalene sulfonate, 4-5 percent of span-80, 1-2 percent of phytic acid, 5-10 percent of base oil 60SN/75SN, 30 percent of kerosene D60 and 28-49 percent of number 120 solvent naphtha. The anti-rust oil has low viscosity and quick draining speed; the surface of the anti-rust oil is smooth and not sticky. Compared with common anti-rust oil, the anti-rust oil has good anti-rust effect, is convenient to use, saves materials, improves the packaging speed of finished products, and has excellent economic benefit.

Description

The special-purpose antirust oil of a kind of iron powder stamping parts

Technical field

The invention belongs to petrochemical industry, relate in particular to the special-purpose antirust oil of a kind of iron powder stamping parts.

Background technology

The consumption maximum of iron powder in powder metallurgy is produced; the main application of iron powder is the manufacturing machine part; when producing iron powder; for mouldability and the plasticity of improving powder adds plasticizer such as gasoline, rubber or paraffin usually; add an amount of demoulding lubricant before the punch forming, under 500～600MPa pressure, be pressed into required form then; stamping parts just becomes the metallurgic product with certain porosity carry out sintering in high temperature furnace that nitrogen protection is arranged or vacuum drying oven after.Produce each operation of stamping parts and usually can not carry out simultaneously,, be easy to the moisture absorption and get rusty, so stamping parts difficult quality guarantee in storage, the process of circulation because stamping parts has certain porosity and odium stearate class demoulding lubricant commonly used.The iron powder stamping parts does not have special-purpose antirust oil, and the universal antirust oil viscosity of using is bigger at present, is difficult for immersing inside, stamping parts space, displacement moisture needs the scene to use with solvent naphtha dilution back, usually can not obtain effective rust-proof effect, cause by the gross stamping parts to be scrapped, economic loss is bigger.

Summary of the invention

The invention provides the special-purpose antirust oil of a kind of iron powder stamping parts, solved the shortcoming of the antirust oil rust-proof effect difference in the background technology.

Technical scheme of the present invention is achieved in that the special-purpose antirust oil of a kind of iron powder stamping parts, the mass percent of each component is: oleic acid 1-2%, triethanolamine 4-9%, petroleum sodium sulfonate 3-7%, dinonyl naphthalene sulfonate barium 3-7%, Si Ben-804-5%, phytic acid 1-2%, base oil 60SN/75SN 5-10%, kerosene D6030%, 120# solvent naphtha 28-49%;

The mass percent of each component is: oleic acid 1.5%, triethanolamine 7%, petroleum sodium sulfonate 5%, dinonyl naphthalene sulfonate barium 5%, Si Ben-804.5%, phytic acid 1.5%, base oil 60SN/75SN 7%, kerosene D6030%, 120# solvent naphtha 38.5%;

The preparation technology of the special-purpose antirust oil of a kind of iron powder casting die:

(1), earlier phytic acid and oleic acid are dissolved in base oil 60SN/75SN;

(2), the mixture with (1) gained is dissolved in kerosene D60;

(3), continuous stirring, triethanolamine is slowly joined in the mixture of (2) gained;

(4), petroleum sodium sulfonate, dinonyl naphthalene sulfonate barium, Si Ben-80 are joined in the mixture of (3) gained;

(5), promptly get the antirust oil product with 120# solvent naphtha dilution (4) resultant mixture.

The invention has the beneficial effects as follows: the made antirust oil viscosity of the present invention is little, and the speed that drains is fast, and product surface is bright and clean tack-free, compares favorable rust preventing effect with universal antirust oil, and is easy to use, saves the materials amount, improves finished product packing speed, has good economic benefit.

The specific embodiment

In order to understand better and to implement, describe special-purpose antirust oil of a kind of iron powder stamping parts of the present invention and preparation method thereof in detail below in conjunction with embodiment: accurately take by weighing oleic acid 1.5kg, triethanolamine 5kg, petroleum sodium sulfonate 6kg, dinonyl naphthalene sulfonate barium 6kg, Si Ben-804kg, phytic acid 1.5kg, base oil 60SN/75SN 5kg, kerosene D6030kg, 120# solvent naphtha 41kg, (1), elder generation are dissolved in base oil 60SN/75SN with phytic acid and oleic acid; (2), the mixture with (1) gained is dissolved in kerosene D60; (3), continuous stirring, triethanolamine is slowly joined in the mixture of (2) gained; (4), petroleum sodium sulfonate, dinonyl naphthalene sulfonate barium, Si Ben-80 are joined in the mixture of (3) gained; (5), promptly get the antirust oil product with 120# solvent naphtha dilution (4) resultant mixture.
