Description
Technical field
The present invention relates to a kind of anticorrosive paint and preparation method thereof, in particularly relating at the bottom of a kind of double-component, face unification thick-film type epoxy turns rust type anticorrosion water-soluble coating and preparation method thereof.
Background technology
Anticorrosive paint, is generally divided into conventional anticorrosive paint and anticorrosive paint, is requisite a kind of coating in paint.Conventional anticorrosive paint is under general condition, and metal etc. plays etch-proof effect, the life-span that protection non-ferrous metal uses；For anticorrosive paint refers to relatively conventional anticorrosion, can apply in relatively harsh corrosive environment, and there is the class anticorrosive paint that can reach the protection period more longer than conventional anticorrosive paint.Anticorrosive paint is generally used for the emerging ocean engineering such as field such as Offshore Units, seashore and bay structure, Modern Traffic is transported such as fields such as the field such as freeway guardrail, bridge, large size industrial enterprise such as food chemistry equipment, canister inside and outside wall, chemical industry, iron and steel.
With conventional anticorrosive paint, anticorrosive paint differs primarily in that its technology content is higher, technical difficulty is bigger, relate to the most many technological progresses and product development, it the most too relies on the knowledge and experience of coating, and it is depending on electronics, physics, ecological, machinery, the multi-disciplinary knowledge such as instrument and management with cross, the synthesis of high corrosion-resistant resin, dispersant with high efficiency and the application of auxiliary rheological agents, the impervious pigment of new type corrosion resistant and the exploitation of filler, the application of advanced construction tool, construction maintenance technology, onthe technology of site test etc., it is required for integrated application among anticorrosive paint and application.So, the level of development of anticorrosive paint is how, and performance is how, becomes the mark of mark one national science technical merit, becomes the mark weighing anticorrosive paint advanced technology.
Anticorrosive paint is including solvent-borne type anticorrosive paint and water-based anticorrosive paint.Solvent-borne type anticorrosive paint is the coating prepared with organic solvent as disperse medium.CN 102433058A discloses one can epoxy ester primer capable of being applied to rusty surface, its formula is: configuration first component, oxygen ester 20%～30%, retarder thinner 20%～30%, filler 15%～25%, rust stabilizer 15%～25%, activity rust resisting pigment 1%～3%, drier 0.05%～0.3%, penetrating agent 0.1%～0.3%.Configuration component B, epoxy resin 26 ~ 33%, oleum lini 40 ~ 44%, Oleum Verniciae fordii 18 ~ 20%, phenolic resin 5 ~ 10%.Its preparation method is: resin and oleum lini mix homogeneously, adds Oleum Verniciae fordii and phenolic resin, prepares epoxy-ester.Add retarder thinner to be allowed to dissolve, then add filler, rust stabilizer, activity rust resisting pigment, penetrating agent and drier, dispersion stirring.
At present; what in the large-scale steel structure bridge that anticorrosive paint application both at home and abroad is more, steel chamber interior wall commonly used is solvent epoxy coatings; but when carrying out the repairing of inwall weld seam after steel box girder assembling, solvent epoxy coatings exists for the problems such as safe and environment-friendly, workmen's protection.
Water-based anticorrosive paint is entirely or primarily using water as solvent or the coating of dispersant, and wherein aqueous epoxy coating is an important research direction of water paint.CN 102627905A discloses a kind of water corrosion-resistant epoxy paint for steel construction protection; its formula is: epoxy resin 40%～60%; dispersant 0.5%～0.7%; high peptide ash 8%～12%, feldspar powder 7%～11%, corundum 5%～9%; pottery differential 4%～8%; nanosilica solution 3%～7%, zinc phosphate 3%～7%, auxiliary agent and firming agent.Its preparation method is: configuration first component, first aqueous epoxy resins, aqueous dispersion is mixed with high titanium ash, feldspar powder, corundum, ceramic, nanosilica solution, zinc phosphate, water stirring.Quickly cross sand mill and improve fineness, add that aqueous defoamer, aqueous levelling agent, water-based thickener, aqueous substrate wetting agents, preventing metal corrosion agent, metal base are anti-to be dodged rust agent and stir.Component B is firming agent.First component and component B 5～7:1 coordinate uniformly by volume.Then construct application.
Although current existing aqueous epoxy coating includes the aqueous epoxy coating safety and environmental protection sold, but the construction of solvent epoxy coatings, process based prediction model can not be reached simultaneously, such as one-pass film-forming 100-150 μm, wearability 750g/500R is less than the non-foaming non-corrosive of 0.050g, salt spray resistance 3000h.
Summary of the invention
