Abstract
The present invention discloses the preparation process of antiwear, anticorrosive nanometer composite epoxy asphalt repair paint. The repair paint has organic surfactant coated nanometer level functional powder in 2-15 wt% added, and the nanometer level functional powder is one or two selected from titania, silica, zinc oxide, nickel oxide, alumina, chromium oxide, manganese oxide and barium sulfate. The nanometer level powder is first dispersed in small amount of epoxy resin through ball milling, sand grinding or high speed emulsification to form slurry, and the slurry is then mixed with the main epoxy asphalt repair paint component to obtain the antiwear, anticorrosive nanometer composite epoxy asphalt repair paint. The composite epoxy asphalt repair paint is used in repairing coated film and has high anticorrosive performance and high scratch resistance.
Description
Technical field
The present invention relates to a kind of preparation method of the coating composition based on Resins, epoxy, relate to a kind of preparation method who adds the epoxy asphalt repair paint of nano-function powder in particular.
Background technology
The ocean is the very harsh environment of corrodibility; nearly all position on oceanographic engineering facility and naval vessel, ocean all needs to carry out anti-corrosion protection; therefore protective system included scope in ocean is very extensive; and the category that all belongs to heavy-duty coating, as rust-proofing primer, ship hull paint, porch paint, interior cabin lacquer, coating container, harbour facility and platform coating, oil tank coating, cooled with seawater pipeline and floating pipe line with coating etc.Zinc-rich paint is one of focus of present oceanographic engineering protective coating.Zinc-rich paint the earliest is to add equivalent zinc powder formulated inorganic zinc rich paint in invention eighties of last century thirties with water glass by Australian Victov Nightingale.Through about 70 years development, zinc-rich paint reaches its maturity, and has developed many types, successfully steamer, offshore production platform, harbour, gate, basin, pipeline, bridge etc. has been carried out favorable protection.Over nearly 20 years, priming paint adopts zinc rich primer, intermediate coat to adopt epoxy-mica ferric oxide lacquer, finish paint to adopt the application system of high-performance weather-proof lacquer to become the measure that domestic and international modern large-scale steel structure fabrication corrosion-proof coating is taked jointly.
Along with the mankind carry out on a large scale drive oing boldly to the ocean, marine economy and marine industries are further upgraded and to development in pluralism, people have higher requirement for epoxy zinc-enriched paint, and epoxy zinc-enriched paint also is one of focus of current oceanographic engineering protective coating.Epoxy asphalt repair paint is the coating that cooperates epoxy zinc rich primer, and when the engineering component that applies coating during owing to reason generation holiday such as construction collision or paint film destruction, epoxy asphalt repair paint can in time be repaired these rejected regions.Certainly, people have also proposed the requirement of higher aspects such as corrosion-resistant and scratch resistance performance, for example permanent protective property energy, low consumption of resources and environmental ecology close friend etc. for epoxy asphalt repair paint.At present, the exploitation of epoxy asphalt repair paint no longer is a protective of only paying attention to coating, and the scientific research personnel attempts to improve its over-all properties when improving the epoxy asphalt repair paint barrier propterty always.It is found that the over-all properties that improves epoxy asphalt repair paint, its key is further to improve the quality of coating integral body after the epoxy asphalt repair paint film forming, and high resistance to corrosion seawater, scratch resistance performance etc. is its important feature.Practice shows that the key that improves the epoxy asphalt repair paint film quality is to select for use the high-performance epoxy asphalt repair paint.
At present, general epoxy asphalt repair paint is by resin, and filler such as zinc powder and subsidiary material are formed.According to the classical corrosion failure mechanism of filming, the corrosion failure of filming in corrosive medium has three kinds of forms usually: the one, and coming off appears in the poor adhesive force of coating and matrix; The 2nd, coating self is subjected to the erosion of media such as acid, alkali, salt and has lost protection to matrix; The 3rd, coating exists defective (as pin hole) or coating impervious poor, and resembling Na+, Cl-plasma can be by spreading, and causes local corrosion thereby the resistance of coating is descended greatly.Epoxy zinc-rich coatingsurface scratch resistance performance depends primarily on the micro-and wear resisting property of coatingsurface.Usually the main path that improves film resistance to corrosion seawater, resistance to marring performance is to adopt performance resins and high-quality filler and auxiliary material etc.But in resin and these traditional mode of production fields of paint filler, offshore company occupies absolute advantage.Offshore company's coating has been grasped and has been monopolized productions such as performance resins, pigment and filler in a large number, separates and gordian technique such as purification, and domestic enterprise does not have advantage in this field and can say.The domestic enterprise's lifting conventional industries technology content that develops into of nanosecond science and technology provides new opportunity.Nanoparticle is owing to have special effectses such as surface effects, small-size effect, quantum size effect, macro quanta tunnel effect, is used for performances such as light that coating can make coating, magnetic, electricity, mechanics and is improved or gives its new function.Improve aspects such as traditional epoxy asphalt repair paint sea water corrosion resistant and scratch resistance performance at employing nano composite powder body technique both at home and abroad and still lack relevant report, the present invention attempts to fill up this blank on the one hand.
