Abstract
The present invention relates to anticorrosion paint, particularly either an anti-corrosion primer that can be painted on damp object surface with little pocking, or a high performance antiseptic primer on low surface treatment requirement that can low-temperature curing. The paint is bicomponent A and B epoxy anti-corrosive paint, wherein component A is composed by epoxy resins, rust protection pigment, fillers, rust stabiliser and osmotic agent, imported high performance ampholytic surface active agent, resist sagging accessory ingredient and water finishing agent, and in grey; the component B is composed by imported high performance special modified amine hardener group, and in brown. The paint has chemical properties like strong adhesive force, good physical mechanical behavior and excellent grease-proof, water resistance, acid and alkali resistance, salt-mist-resistance and heatproof, can be used together with most paints, has long service life because most surface treatment process can be avoiced, hence a great amount of paint time and expenses can be saved; the invention can be broadly applied in industries like ship, chemical industry, machinery etc. as matching primer on low surface treatment or anti-corrosive paint alone.
Description
Technical field
The present invention relates to a kind of protective system, especially refer to both can directly be coated with the body surface that is contained in humidity and has a small amount of corrosion simultaneously, the high-performance of low-temperature curable, low surface treatment require anti-corrosion primer again.This coating is the two component epoxy protective system, the protection against corrosion result of use reached more than 10 years, the first component is formed rust by Resins, epoxy, antirust face, filler, corrosion stablizer and permeate agent, Imported High-performance amphoterics, sag prevention auxiliary agent, moisture content treatment agent etc.Component B is made up of Imported High-performance special modified amine hardener group etc., and is brown.
Background technology
In coating project, steel surface is handled quality, is vital to the influence in film performance and life-span.In various rust cleaning modes, hydroblasting has characteristics such as high-level efficiency, high quality and low expense, low pollution, obtains application more and more widely abroad, just progressively replaces the derusting by sandblast mode that environment is caused very big pollution at home.But after the hydroblasting, steel surface can produce " returning rust " phenomenon in half an hour, and surface moisture is very big, and domestic existing coating can not directly carry out application.In addition, construct in harsh corrosive environment, clean corrosion can't be removed in many applications position; At some high humidity environment, steel surface constantly has water to ooze out, and has greatly influenced the antiseptic property of coating.Make a general survey of domestic coating variety, also do not have a kind of both can be with simultaneously rust, the wet application of band, again the coating of low-temperature curing in the winter time.
Summary of the invention
In view of this, purpose of the present invention overcomes the deficiencies in the prior art and shortcoming exactly, and provide a kind of directly in moist, the application of little rust steel surface, and have chemical properties such as extremely strong sticking power and excellent physical and mechanical properties and excellent oil resistant, water-fast, acid and alkali-resistance, salt spray resistance and heatproof, can with the good supporting high-performance long-acting low surface treatment epoxy coating of most coating.
The object of the present invention is achieved like this: earlier Resins, epoxy is poured in the solution of being made up of mixed organic solvents and stirred, disperse, make its whole dissolvings, about 2～3 hours.Add moisture treatment agent, permeate agent, toughner, high speed dispersion 0.5～1 hour is to mixing.Add various corrosion stablizers and transforming agent more successively, antirust face, filler stir, disperse, be ground to suitable fineness and viscosity through sand mill, in the packing jar, disperse slowly to add anti-settling agent at last, make long acting low surface treatment epoxy coating with middling speed.It is characterized in that: prescription by weight is:
