Description
Technical field
The present invention relates to a kind of rust-proofing wax, this rust-proofing wax is applicable to the surface of various steel, precision instrument, cast member and processing parts etc. and protection against the tide and the rust protection of inner chamber, and the antirust processing situation cheaply such as sewer line, plant effuent discharge line and the corrosion of boat landing salt fog resistance; The invention still further relates to purposes and the using method of this rust-proofing wax.
background technology
Iron and steel metalloid (as steel, automobile and cast member etc.), under natural storage condition, because environment and other factors make the easy corrosion of parts, thereby reduces or loses use value, causes security incident and financial loss.China is every year because the direct economic loss number that corrosion of metal causes is huge.
Corrosion of metal is mainly divided into chemical corrosion and galvanic corrosion mechanism.The reason that produces corrosion has a lot, as physical abuse, surface imperfection, subsurface defect, environmental factors etc.In physical environment, moist and high temperature can accelerate these reactions, also can aggravate reaction near dew-point temperature and freezing point temperature.Common corrosion factor has following some approach.
A, ingress of air: airborne oxygen, moisture content, sour gas, dust etc. can with iron and steel generation chemical reaction, when many factors exists, can mutually promote corrosion is accelerated.Such as in region following the line of the sea, in air, contain higher salinity; The harmful chemicals such as the formed acid rain of industrial pollution also can increase the weight of the corrosion to iron and steel.
B, surface contamination: greasy dirt, dust and acid, alkali, the salt etc. that are attached to workpiece surface are converted into corrosive medium at certain condition, with the composition generation chemical reaction in steel part, produce chemical corrosion and get rusty.Research shows, as long as there is the chloride ion content of 4～6mg/L, is just enough to destroy the passive film on steel surface.Northern area in the winter time in order to prevent or eliminate the vehicle slip of road surface because snowing and freeze and producing, conventionally all can spray cheap salt solution and carrys out snow melting or change ice on road, and automobile leaves out-of-date, and salt solution is splashed to vehicle body especially on chassis and produce corrosion.
C, galvanic corrosion: other element impurity in steel part forms galvanic cell and produces galvanic corrosion with iron after crevice corrosion medium.Welding, cut slag, the impurity metallic elements of the generation such as splash is attached to surface, also can form galvanic cell with corrosive medium.
D, surface tear: the destruction of various scuffings to painting protective layer, protection metal and passive film, its protective capability is reduced, easily react with chemical mediator, generation chemical corrosion and getting rusty.
E, roasting school: the composition of flame heating region and metallographic structure change and inhomogeneous, with corrosive medium formation galvanic cell and produce galvanic corrosion.
F, material defect: the chemical imperfection of steel matter (composition is inhomogeneous, C, S, P impurity etc.) and surface physics defect (loose, sand holes, crackle etc.) are conducive to form galvanic cell and produce corrosion with corrosive medium.
G, stress corrosion: the place of stress concentration easily forms stress corrosion.
In order to prevent getting rusty, many measures have been adopted, as use galvanized sheet material, it can protect metallic surface well, but can not guarantee non-corrosive completely, easily there is corrosion in the boring that the edge of galvanized sheet cutting, dress screw are used and the weld of galvanized sheet, zinc also can attenuate as the anode of galvanic corrosion until exhaust, thereby the protective effect of losing.As make Passivation Treatment, not only technical requirements is high, and because of after the damage of physics or chemical reaction, by putting and the damage propagation rate of face is very fast and be difficult for repairing.Stainless steel, due to its special metallographic structure and surface passivated membrane, makes its more difficult and medium generation chemical reaction in the ordinary course of things, but also can be corroded in specific situation.Under the simultaneous condition of corrosive medium and inducement (as scratched, splash, welding etc.), also can there is slowly chemical reaction and electrochemical reaction and be corroded with corrosive medium in stainless steel, and corrosion speed under certain condition produces corrosion phenomena, especially spot corrosion and crevice corrosion quite soon.
Priming paint, the finish paint of car surface spraying can cut off contacting of the chemical corrosion sources such as oxygen in air, water, acidic and alkaline gas and dust and car body metal effectively, thereby prevents to get rusty.Although paint film has certain intensity and sticking power, has work-ing life, can not stop the generation of corrosion completely.The main component of paint film is polymkeric substance, can be because of factor degradeds such as the radiation of sunlight middle-ultraviolet lamp, atmospheric oxidations after long-time use, and also can be because difference variation repeatedly etc. is former thereby weaken its sticking power to metal.External impacts more easily makes paint film impaired, and the collision of scratch or stone all can make automobile metal come out ingress of air and corrode.Once just acceleration is brought out in corrosion, along metallic surface diffusion, because be carries out below priming paint, be often difficult for discovering.In maintenance, find that a lot of outward appearances paint fair vehicle, its underpart metal is seriously corrosion, thereby makes the security intensity of metal lose assurance.
Body of a motor car, after integral body completes welding, need carry out cathode electro-coating, and vehicle body is more comprehensively protected, and guarantees the antirust time that electrophoresis position is certain.But this can only provide the protection at electrophoresis position, because the shielding effect of electric charge in cavity, the cavity inside of vehicle body cannot be implemented, and Here it is, and many vehicles start the reason of corrosion from inside.This internal corrosion is often more dangerous than extraneous rust, because the disguise of corrosion, and vehicle position corrosion open-work usually while by the time observing.
Along with the development of technology, some high-grade automobiles have also adopted the method for Electronic Protection and galvanic protection to alleviate galvanic corrosion now, have obtained certain effect in recent years, but cost costliness and protection effect are also limited.
In the protection against corrosion of metal products, applying maximum is that surface anticorrosion is processed.Conventional method generally has: surface brush is painted processing, Passivation Treatment, painting antirust grease, sprayed compound paint etc.The former two not only cost is high, and finished product in the middle of not being suitable for; Although it is with low cost easy to use to be coated with the method for antirust grease, also have that intensity is low, Anti-temperature difference, sticky hand, the shortcoming that easily runs off.
Metallic surface sprays the advantage that compound paint combines former three, is just progressively widely used at present.And its rush-resisting material used mainly contains two kinds, a kind of is to take rubber, wax, mineral oil and non-ferrous metal etc. to be the compound paint on basis, can effectively control the generation of metallic surface rust staining.Its advantage is high resilience, the shock of available buffer rubble, and cohesive force is strong, and anti oxidation time is long.In automobile protective, be mainly used in the positions such as automobile chassis, shirt rim; But use range is limited, occupy material behavior and traffic safety reason, generally at positions such as heat insulation guard shield, vapor pipe, oil pipe, brake system, universal joint and heat dissipation tanks, must not spray.Another kind of material is translucent cerul composite membrane, can form in metallic surface one deck chemical glue, as metallic surface film, to intercept the contact of moisture content, be specifically designed to windshield frame, bonnet, chassis skeleton, shroud upper panel, all car door inner chambers and luggage etc.
Traditionally, rust-proofing wax is usingd petroleum wax, biological wax (vegetable wax, animal wax) and the low molecular weight olefin polymerization thing main matrix material as rust-proofing wax.CN1386812A discloses a kind of antirust liquid wax for automobile, and Component comparison is single, and surface strength and glossiness are inadequate, is not suitable for the maintenance for precision instrument, and stripper-resistance is poor, and its high temperature resistant property is unknown.CN1488699A discloses a kind of water-based metal antirust protective agent, for improving its emulsifying effectiveness, has used the component of a large amount of polar functionalities, and weather resistance is not good enough.CN1766023A discloses a kind of water-based rust proof protection treating wax agent; by wax, resin, auxiliary agent, emulsifying agent, sanitas and water, made; this cerate is applicable to the conservation treatment of mechanical fitting lacquer painting; its wax content is low and the higher cost that causes of auxiliary agent content is higher, and particularly the antirust time needs further to improve its rustless property.CN101418186A discloses a kind of water-based rust proof protection treating wax agent, and it is to be made by Wax, synthetic resins, organic multicomponent amine acid salt, tensio-active agent and water, although be easy to use, surface strength and high temperature resistant property also need further raising.
