The coating has high solid content, low viscidity, strong permeability, lower VOC (Volatile Organic Compound), great adhesion, corrosion resistance, and the like, can be applied to the rust surface of low-surface-treated steel material and coatings of water-based inorganic zinc, and the like, can be compatible with coatings capable of matching an epoxy coating and have favorable effect.
Description
Technical field
The present invention relates to a kind of epoxy resin primer.
Background technology
It is reported, the steel iron facilities long-term exposure is in atmosphere, and the amount that annual corrosion is scrapped accounts for more than 20% of iron and steel ultimate production.For preventing corrosion, the most simple and effective method is protected with coating.
And giving full play to of anticorrosion with coat performance mainly depends on good surface treatment, when steel surface application traditional coating, usually all require thoroughly to eliminate rust (>=Sa2.5 level).Generally, in steel construction maintenance construction expense, rust cleaning accounts for 45%.In the maintenance process of the large-scale steel structure of having built up, as the ship structure compactness, be subject to the restriction of execution conditions, often adopt craft or power tool rust cleaning during maintenance, so be difficult to carry out surface treatment thoroughly, must be also on surface can residual iron rust, aging paint film and corrosive medium etc., in this case, to metal finishing, require high, performance good rust proof paint more also is difficult to play a role, can not get the preservative effect of expection, its life-span only has half of original design life-span even lower usually, therefore need to a kind ofly can directly carry out the high-performance of application with rusty surface this, the coating that low prepared surface requires, to reduce the surface-treated workload, the needs that adapt to maintenance engineering.And this coating must have remarkable infiltration and chelating ability, can be penetrated in the rust staining that is attached to the iron-based surface, play the effect of stable solid rust, so just can reduce or save the surface treatment of rust cleaning, can significantly reduce painting cost, improve the preservative effect of composite anti-corrosive coating, the maintenance of boats and ships, steel construction coating is had a very big significance.
In addition, what the large-scale steel structure long-effective corrosion was relatively more commonly used at present is aqueous inorganic zinc-enriched coating, and coatingsurface is comparatively coarse, porosity is larger, before the coated surfaces coating, need one seal coat confining surface pore, in order to avoid the defect such as pin hole occurs after the finish paint application.This seal coat is generally that solvent type epoxy cloud iron-dope adds about 70% solvent latting drown and forms, the volatile quantity of organic volatile (VOC) is very high, pollution to environment during construction is very severe, against the original intention that adopts water-borne coatings, the height infiltration seal coat that necessary exploitation matches with the aqueous inorganic zinc paint for this reason, meet the requirement of antiseptic project.
At present, due to the development of oceanographic engineering, large-scale lasting concrete works increases, also more common for the high epoxy coating permeated of low viscosity that keeps in repair distress in concrete.Domestic height infiltration epoxy coating great majority are applied to the protection of industrial concrete, terrace, are solvent based coating mostly.
The modified epoxy priming paint that has stable solid rust, chelating function in patent is single-component normally, is generally flexible low viscosity epoxy coating, but low viscosity epoxy coating normally solids content is lower, organic volatile content (VOC) is very high.
Existing domestic and international technical target of the product is in Table 1.
Table 1 is technical target of the product both at home and abroad
External priming paint shown in table 1 is typical product on market, is the epoxy primer of two components.Introduce it according to its data and there is low viscosity, hypertonicity, can be used for the reduction process steel surface, old paint film is had to adaptability.By test, find, the viscosity of this priming paint is 17 seconds.But its organic volatile (VOC) content is very high, this product description is introduced the VOC value for 204g/L, but national coating quality Supervision Test Center detects the VOC value of the said firm reaches 360g/L, on domestic market, typical product is the solvent-borne type seal coat, and organic volatile (VOC) content is equally very high.On the non-solvent epoxy priming paint market of high solid, hypertonicity, low viscosity, low VOC (VOC), yet there are no.
