Description
Technical field
The present invention relates to field of metal surface treatment, and in particular to a kind of water base non-phosphor degreaser antirust wax removing agent of metal and
Preparation method and application.
Background technique
For metal works after polishing wax polishing, wax dirt is just viscous with Mechanical Adsorption, intermolecular absorption and electrostatic force absorption etc.
Subsidiary formula formula remains on workpiece.The main component of buffing wax has mineral oil, vegetable and animals oils, paraffin, native paraffin, resin, stearic acid
And abrasive material etc..At present metal paraffin removal stain, degreasing, degreasing method mainly have following a few classes: organic solvent method, chemical method,
Electrochemical process and aqueous cleaning agent method etc..Common organic solvent cannot completely remove buffing wax, metal oxidation especially thereon
The polishings such as object, carbide material cannot be washed effectively；And not only toxicity is big for chlorinated solvents, and has tendency towards hydrolysis, in moist item
Under part, corrosion is had to workpiece；Meanwhile chemistry, the degreasing of electrochemical process paraffin removal will use strong acid or highly basic, can corrode metal,
So also should not be used in cleaning.
Aqua type wax removing agent be using water as decentralized medium, it is green non-poisonous, mainly by the reversal effect of surfactant,
Wetting action, the effect of osmosis and washing, the wax being attached on surface of workpiece is disposed.Therefore, its use
Effect is temperature controlled.In general, when temperature rises, the washing ability enhancing of cleaning agent, this is because when temperature increases, meeting
Accelerate the solution rate of wax, but high temperature will cause the wasting of resources, also increase operating cost.
Although in addition, a variety of wax removing agents currently on the market can clean to a certain extent metal surface buffing wax and
Grease, but due to its component, content and technologic defect, rust-preventing characteristic is very poor, the metallic article after cleaning gets rusty easily, because
This, can add some corrosion inhibiter to improve the rustless property after metal cleaning in wax removing agent.Most commonly used in the market is to have
Machine phosphorus corrosion inhibiting and descaling agent, not only anticorrosion-antiscaling effect is good for organophosphorus corrosion inhibitor, and heavy metal in water will not be brought as chromate
Pollution, will not generate calcium phosphate precipitation as inorganic phosphate.However, a large amount of of organophosphorus corrosion inhibitor use the but row of causing
Discharge water the eutrophication of body, endangers environment, and country had begun the use of limitation high concentration organophosphor scale inhibitor in recent years.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of water base non-phosphor degreaser antirust wax removing agent and its systems
Preparation Method and application are suitable for various metallic articles, clear without high temperature such as steel, stainless steel, copper, aluminium, zinc and its alloy surface
It washes, the dirts such as buffing wax, polishing wax, grease, greasy dirt, the dust of metal surface can be removed under room temperature, has and uses concentration
It is low, permeability is strong, low bubble, the advantages that paraffin removal is high-efficient, without strong acid, sodium hydroxide and inorganic salts, non-combustible, do not hurt matrix,
Cleaning solution chemical stability is good, long service life, is free of APEO nonionic surfactant, green non-poisonous, not phosphorous, after discharge
Will not polluted-water environment, and have good rustless property.
To achieve the goals above, the present invention provides a kind of water base non-phosphor degreaser antirust wax removing agent, by following weight ratio
Formula composition:
Anionic carboxylic acid type high molecular surfactant 15 ~ 20%,
Diethanol amine oleate soap 15 ~ 20%,
Polyvinylpyrrolidone 10 ~ 18%
Alkanolamide phosphate 9 ~ 16%
Diene base succimide 6 ~ 10%,
Penetrant t A-2 5 ~ 9%,
S- carboxyethyl sulfosuccinic acid 1 ~ 3%,
Polyethylene glycol 400 10 ~ 15%,
Surplus is deionized water.
Wherein, the anionic carboxylic acid type high molecular surfactant include water-soluble polyacrylic acid and its copolymer,
Butenoic acid and its copolymer, acrylic acid copolymer-maleic anhydride etc..High molecular surfactant molecular weight is high, good in addition to having
Dispersibility, except emulsibility and foam stability, compared with the common low-molecular-weight, anionic surfactant of wax removing agent, also have
Less toxic, good film forming, adhesiveness, the cleaning agent containing high molecular surfactant can be after cleaning metal on its surface
One layer of film that adhesive force is good is formed, improves the paraffin removal degreasing of cleaning agent with antirust agent, other surfaces activating agent synergistic effect
And rustless property, it can especially improve the lasting rustless property of cleaning agent.
Diethanol amine oleate soap is a kind of low molecule anionic surfactant, relative to other higher fatty acids, oleic acid
Water solubility, stability in hard water, high/low temperature paraffin removal ability it is all more prominent, and this team finds under study for action, compared with monoethanolamine
For triethanolamine, diethanol amine has the effects that good inhibition, infiltration, complexing, alkali reserve, therefore the present invention uses
Diethanol amine oleate soap and carboxylic acid type high molecular surfactant improve cleaning as Compositional type anionic surfactant
The paraffin removal oil removing performance of agent.This team finds that the compound that the molar ratio of oleic acid and diethanol amine is 1: 2 removes in R&D process
Wax performance is best, therefore the diethanol amine oleate soap for selecting the molar ratio to be formed.
Polyvinylpyrrolidone PVP is a kind of nonionic polymer surfactant, has good dispersibility, emulsibility
And fouling resistance, also there is film forming, caking property, solubilization, on the one hand, PVP can be with anionic polymer surfactant
Common film forming, after being cleaned with cleaning agent, metallic substrate surface can cover one layer of high adhesion force, uniform and stable film, prevent
Rust agent is dispersed in this layer of macromolecule membrane, metal is isolated from the outside, this " barrier " can further increase Metal Substrate
The rust-preventing characteristic of body.On the other hand, PVP is as nonionic surfactant, can simultaneously with anionic surfactant and its
Its nonionic surfactant compounding, this synergistic effect can express lower surface tension, and the interface for improving cleaning agent is living
Property, soil removal efficiency is greatly improved, good cleaning effect is obtained.
The present invention also uses answering for nonionic surfactant alkanolamide phosphate 6503 and anionic surfactant
Match, by the addition of anionic surfactant, expands the cloud point spread of nonionic surfactant, epoxy glue can be formed
Group.Due to " insertion " of nonionic surfactant molecule, so that the repulsion of ionic portions drops between anionic surfactant
It is low, then by the interaction between two surfactant hydrophobic chain micellas, so that the generation of micelle becomes easier to, thus
Decline the critical micell value of solution, surface tension also declines, and surface-active increases.Alkanolamide phosphate 6503 in hard water and
There is extremely strong dirt-removing power in salt water, which does not have cloud point, can have to animal oil or mineral oil without high temperature good
Removing ability also has good foam stability, excellent emulsification and rustless property in cleaning.
Diene base succimide T154 be oil-soluble macromolecule dispersing agent, have rust-preventing characteristic, low temperature dispersity outstanding,
Solubilization and preferable high-temperature stability, the dispersibility in oil medium are generally significantly larger than low molecule dispersing agent.
The low bubble of penetrant t A-2, high cloud point, have fabulous adhesive force, penetration is stronger, shows one stream in high temperature or low temperature
Oil removing and paraffin removal ability, S- carboxyethyl sulfosuccinic acid is a kind of environmentally protective high-efficient corrosion inhibitor, and treatment effect is better than phosphorus system
Corrosion inhibiter, and be easily biodegradable, pollution will not be brought to environment, polyethylene glycol 400 cosolvent can increase between component
Dissolubility, improve the physics and chemical stability of cleaning solution.
