Abstract
The invention discloses a kind of preparation methods of metal rust preventing lotion, belong to metal rust preventing technical field.The present invention is first modified sodium lignin sulfonate with halogenated hydrocarbons, and being divided to modified sodium lignin sulfonate 2:1 in mass ratio is two parts, wherein quality is biggish is denoted as No. 1 concentrate, quality is lesser to be denoted as No. 2 concentrates, No. 1 additive is made in No. 1 concentrate and nano silica, according to parts by weight, it successively weighs: 60~75 parts of water, 2~8 parts of mixed amines, 5~8 parts of epoxidized soybean oils, 2~4 parts of surfactants, 10~15 parts of rust-inhibiting additives, 3~8 parts of mixed alcohols and 2~4 parts of barium sulfate, machine amine is blended with to mix with water, and epoxidized soybean oil is added, rust-inhibiting additive, mixed alcohol and barium sulfate, after being stirred, obtain metal rust preventing lotion.Gained metal rust preventing lotion of the invention has excellent rustless property.
Description
Technical field
The invention discloses a kind of preparation methods of metal rust preventing lotion, belong to metal rust preventing technical field.
Background technique
Metal material is the basis of human civilization substance, and does not also give human society in the metal erosion of progress all the time
Cause massive losses.For example, building, equipment, aircraft, aircraft carrier, cable, metallic conduit etc., corrosion can be to the outer of metal
Shape, gloss and mechanical performance cause irreversible destruction and loss, and some even can directly make scrap of the product, to cause to provide
The waste in source endangers the life security of the mankind.Metal processing piece is during production and processing and transport, it is easy to it gets rusty, this
It just needs to form thin film in metal surface using antirust oil, prevents the chemicals of corrosion of metal.So-called rust be due to oxygen and
Water act on metal surface generate oxide and hydroxide mixture, iron rust be it is red, patina be it is green, and aluminium and
The rust of zinc claims white rust.Machinery is difficult not contact with oxygen, moisture or the other corrosive medias in air in operation and storage, this
A little substances will occur electrochemical corrosion in metal surface and get rusty, and prevent corrosion from the above substance must be prevented to contact with metal.
Antirust agent belongs to one kind of antirust product, and other types of there are also antirust oil, anti-tarnish papers etc..
In bearing parts process, metal working fluid directly acts on lathe, workpiece and tool surface, therefore it is required that
Working fluid has good rustless property.Especially high temperature, high humility area or season, if the bearing parts process-cycle compared with
It is long, then the rustless property of metal working fluid is required higher, it is desirable that working fluid itself will not cause to become rusty to workpiece, lathe and cutter
Erosion, while should also have certain rustless property, it can play the role of temporarily preventing corrosion.Synthesize metal working fluid cooling
Can be good, it is economic and environment-friendly, it is used widely in bearing parts process.But synthesis metal working fluid is usually used in use
Water dilution, water content is higher, and contact component is easy to cause to corrode, so the selection of antirust agent and compounding are to improve metal working fluid
One difficult point of rustless property has great importance to guarantee metal processing piece quality.The water-based antirust of early stage contains more
Nitrite, chromate or phosphate, except with stronger toxicity, causing environmental pollution or be discharged into water to generate eutrophication
Outside, also one layer of bloom can be formed in metal surface, the adhesive force of painting layer is influenced after coating.Therefore there is an urgent need to a kind of antirusts
Effect is good, environmental-friendly, does not influence the water-based antirust of subsequent handling service performance.Currently, common aqueous rust preventive is to metal material
Preservative treatment is carried out, aqueous rust preventive is that water-soluble organic inhibitor and surfactant, bleeding agent etc. is added using water as basic material
Be formulated, but due to the water-soluble limited time of organic matter, precipitating be easy to appear in storing process, influence product appearance and
Performance is not able to satisfy people's demand gradually.There is researcher to invent a kind of metal rust preventing lotion, raw material includes: O-phthalic
Acylamino- acetic acid alcohol amine salt, acetyl triethyl citrate, tetrabutyl ammonium acetate, defoaming agent, surfactant, dimethyl hydroxyethyl are fine
Dimension element, water-base resin and water.The preparation method for also proposing metal rust preventing lotion, includes the following steps: phthaloylamino
Acetic acid alcohol amine salt, acetyl triethyl citrate, tetrabutyl ammonium acetate are added to the water, and heating stirring is uniform, and prefabricated material A is made；It will
It is 7.5~9 that water-base resin, which adjusts pH value, is added in prefabricated material A, adds defoaming agent, surfactant, methyl hydroxyethyl cellulose
Element stirs evenly, and metal rust preventing lotion is made.Good film-forming property, the cohesive force of this antirust emulsion are strong, anticorrosion is high-efficient, green
Environmental protection.But the problem of traditional metal rust preventing lotion can not be further increased there is also rustless property at present, therefore also need pair
It is studied.
Summary of the invention
The present invention solves the technical problem of: it can not be further increased for conventional metals antirust emulsion rustless property
