Abstract

The invention discloses a kind of waste heat black film special anti-rust oil, count by weight percentage, component content is as follows for each material component：3 10 parts of sulfonate rust-inhibiting additive, 8 15 parts of film forming agent, 0.1 0.5 parts of antioxidant, 26 parts of cosolvent are oily based on surplus；Wherein described film forming agent is lanolin fatty acid pentaerythritol ester and oleamide.In antirust oil of the present invention, lanolin fatty acid pentaerythritol ester and oleamide have better affinity with waste heat black film, under the action of cosolvent, can preferably spread over waste heat nigrescence film surface.And film forming agent additive amount helps to fill up in the gap in waste heat black film, and the agent material that forms a film is macromolecular, is long-term stored in warehouse and is not easy to volatilize much larger than the addition in conventional common antirust oil.In addition, adding in part Sulfonates rust-inhibiting additive in the present invention, it can adsorb and not by the metal surface of film forming agent polymerization crosslinking, play good rust-proof effect on a small quantity.

Description

Waste heat black film special anti-rust oil and preparation method thereof
Technical field
The present invention relates to a kind of waste heat black film special anti-rust oils and preparation method thereof, belong to metal surface treatment technology neck Domain.
Background technology
It is increasing to demands such as standard components with the fast development of the industries such as modern mechanical, national defence, automobile making, And the quality requirement of standard component is also improved therewith.Therefore, the cost standard part production of the antirust treatment of standard component, fortune An important step defeated, in storage process.Waste heat nigrescence is to make iron and steel parts using tempering waste heat in heat treatment process Surface polymerize with the macromolecule film former in waste heat blackening agent for surface, forms the technology of surface protection and decorative effect.Standard component passes through After nigrescence, a part of standard component manufacturer selection is impregnated or spray coating mechanical oil, although at low cost, the salt fog time of standard component It is short, especially risk of getting rusty is susceptible in summer.A part of standard component manufacturer selects common antirust oil on the market, although centainly The salt fog time is improved in degree, reducing summer gets rusty risk.Lack in existing market for the special antirust of waste heat black film Oil.
By being carried out to waste heat black film the study found that the filmogen of waste heat black film is polyacrylic acid or polyacrylic acid Ester；Common antirust oil and the contact angle on its surface are more than common antirust oil and the contact angle of bare metallic surface, cause commonly anti- Rust oil effectively can not be sprawled and soaked on waste heat black film.What waste heat black film was formed in metal surface is not fine and close Film, wherein having certain gap, if antirust oil effectively cannot be covered or blocked, it will standard component antirust is caused to fail.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of waste heat black film special anti-rust oil, without sodium nitrite, The not environmentally composition such as chromate, phosphate without easily leading to remaining silicate, and can effectively inhibit superposition and look unfamiliar rust.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of waste heat black film special anti-rust oil, count by weight percentage, component content is as follows for each material component：
Wherein described film forming agent is in lanolin fatty acid pentaerythritol ester and oleamide.
Preferably, the sulfonate rust-inhibiting additive for barium mahogany sulfonate, dinonyl barium mahogany sulfonate, petrolic magnesium sulfonate, Petroleum sodium sulfonate, middle base number calcium mahogany sulfonate, calcium sulfonate with high base number, synthesis sulfonic acid magnesium, synthesis barium sulfonate, calcium alkylbenzenesulfonate, conjunction Into sodium sulfonate, alkaline dinonyl barium sulfonate, neutral dinonyl naphthalene sulfonate barium one or several kinds.
Preferably, cosolvent is selected from polyol ester, polyol ester polyoxyethylene ether, fatty alcohol polyoxyethylene ether, fatty alcohol Polyoxyethylene ether fatty ester, alkylphenol polyoxyethylene ether, alkylphenol polyoxyethylene ether aliphatic ester.
Preferably, the antioxidant is phenols.
Preferably, the antioxidant is 2,6-di-tert-butyl p-cresol or 2,7- di-t-butyl mixed phenol.
Preferably, the base oil at 40 DEG C viscosity in 5-30mm2/s。
The invention also discloses the preparation method of above-mentioned waste heat black film special anti-rust oil, step includes：By 40- 70% base oil is added in reconciling in kettle, is heated to 60-80 DEG C, is then added in antioxidant, rust-inhibiting additive, film forming agent, helps Solvent is stirred to all substances and fully dissolved, and is eventually adding remaining base oil, is stirred evenly.
Compared with the prior art, technical solution of the present invention have the advantage that for：
In antirust oil of the present invention, lanolin fatty acid pentaerythritol ester and oleamide have preferably with waste heat black film Affinity under the action of cosolvent, can preferably spread over waste heat nigrescence film surface.And film forming agent additive amount is much larger than Addition in conventional common antirust oil, helps to fill up in the gap in waste heat black film, and the agent material that forms a film is big point Son is long-term stored in warehouse and is not easy to volatilize.In addition, adding in part Sulfonates rust-inhibiting additive in the present invention, can inhale It is attached on a small quantity not by the metal surface of film forming agent polymerization crosslinking, plays good rust-proof effect.
Compared with conventional antirust grease, conventional antirust grease needs to heat to be used the present invention, and is formed very in workpiece surface Thick oil film.Energy loss not only is caused to production process, but also influences the installation and use in downstream.The waste heat of the present invention blacks Special anti-rust oil can be used, one layer of very thin oil film only formed in workpiece surface, you can play anti-rust action at normal temperatures.
