Description
Technical field
The present invention relates to anticorrosive metal field, specially a kind of water base Anti-corrosion wax composition and its application, institute of the present invention
The water base Anti-corrosion wax composition stated is applied at positions such as automobile industry chassis, cavity, hinges.
Technical background
Metal is widely used in current industrial and civilian industry, such as Aero-Space, automobile, household electrical appliances, building, boat
Sea etc..The anti-corrosion of metal also just becomes metal one of necessary problem to be processed in application process.Nowadays, many technologies
Different degrees of contribution can be made for the anti-corrosion of metal, such as, by coating the modes such as antirust fluid, metal can be obtained
Temporary protection；By the coating of coating, metal can be made to obtain longer Corrosion Protection；Partial coating and passivation
(zinc-plated and Cr VI), or metal tape carrys out certain antiseptic property.
It is more traditional antirust means that the mode of steel coating antirust fluid carries out anti-corrosion, using the pole in antirust fluid
Property corrosion inhibiter composition to the absorption film-forming of steel surface, and then reach the effect for intercepting corrosive medium.But it is because binding molecule
Film forming thickness is thin, and adsorption strength is not enough, and film forming is easily destroyed, so not reaching long-term corrosion-resistant purpose.Additionally, antirust oil makes
Volatile solvent can bring certain body harm to user, and inflammable and explosive, there is potential safety hazard.
The comparatively safe environmental protection of water-repellent preservation material, but because water soluble rust inhibitor molecular weight is small, adsorption capacity is weak, and film forming is not
Densification, is easily washed and is dissolved with counter, it is impossible to reach long-term corrosion-resistant purpose.
For cavitation corrosion aspect, patent CN201310439006 provides a kind of method, using vapour phase inhibitor in normal temperature
The principle with certain vapour pressure, introduces this vapour phase inhibitor in antirust oil down, by the volatilization of vapour phase inhibitor, absorption
Certain anti-rust action is played to cavity structure metal inner surface.But, this kind of volatile rust preventive oil still can volatilize solvent, and anti-
Rust oil does not reach long-term corrosion-resistant effect in itself.
Solvent-borne type rust-proofing wax improves original hot melt casting mode because its antiseptic property high is in automobile industry extensive use
Many deficiencies, patent CN02115915 introduces a kind of liquid flux type automobile rust-proofing wax.But the solvent used by it is mainly aromatic hydrocarbons
Class, esters, alkanes oil product, volatility are stronger, inflammable and explosive, there is security risk, irritant, big to harm.
Patent CN200610024565 describes a kind of production method of emulsified antiseptic wax, with emulsify in the form of by water with add
Plus agent mixing, reach nonflammable security purpose.But, this form is not appropriate for long-term corrosion-resistant automobile inner cavity high makes
With ponding position while welding easily causes reversely emulsification, and film forming is easily washed, while being unable to reach the longer-term anti-corrosion cycle.
Therefore, it is an object of the present invention to provide a kind of water base Anti-corrosion wax composition with anti-corrosion function high, garage is met
Processing performance of the industry in the spraying operation at the positions such as chassis, cavity, hinge.This Anti-corrosion wax composition, is different from tradition aqueous
Emulsification form, is to be dispersed in water the materials such as wax class material, filler with high shear discrete form, uses a small amount of table
Face activating agent stablizes its dispersity, it is to avoid the anti-molten and reverse emulsification problem that exhibiting high surface activating agent is caused, meanwhile, utilize
The characteristics of normal temperature of unsaturated-resin spontaneously dries film forming, increased the compactness and water proofing property of cere, not only solve tradition
Flammability hazard and VOC the volatilization safety issue of solvent based product, while, there is provided long-term anti-corrosion capability.
