Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical iron oxide red anticorrosive paint and preparation method thereof.
Background technology
Rust-inhibiting paint a kind ofly protects the chemistry of metallic surface from air, seawater etc. or the coating of galvanic corrosion.Mainly be divided into physical property and the large class of chemically antirust paint two.The former leans on the suitable cooperation of pigment and paint vehicle, forms fine and close paint film to stop the intrusion of corrosives, as iron oxide red, aluminium powder, graphite rust-inhibiting paint etc.; The latter presses down rust effect, as barium sulfate, zinc yellow anticorrosive paint etc. by the chemistry of rust-stabilising pigment.Antirust for metals such as bridge, boats and ships, pipelines.Barium sulfate rust-inhibiting paint is the paint that a kind of barium sulfate and siccative oil mix.Its perviousness, wettability are good, and paint film is soft, attachment is strong, but drying is slower.In addition because barium sulfate is than great, easily precipitate, and stored for a long time can be thickening, brushing property is also poor.
The rust-inhibiting paint used is roughly oiliness and water-based two kinds.Oily antirust varniss makes the greasy removal difficulty of material surface, seldom uses.Oily antirust varniss is easy to use, cheap, but because of containing the toxic substance such as nitrite, chromic salt, comparatively large to operator's harm, country limits use, and these type of product performance are single, can not meet the antirust requirement of magnetic alloy material.Epoxy anti-rust paint is used for polymeric amide as solidifying agent, and dihydroxyphenyl propane dimethylbenzene is cakingagent, and film is good to substrate adhesion, and workability is good, and paint film flexibility is good, water-fast, oil resistant chemicals-resistant is good.Add different rust-stabilising pigments, different rust-inhibiting paints can be mixed with, mostly be priming paint.
Water-based metal rust-inhibiting paint selects the powerful sequestrant myo-Inositol hexaphosphate of metal to be main component, and several aqueous promoter is composite forms with other.Myo-Inositol hexaphosphate is the Nantural non-toxic Organic chemical products extracted from food crop; when it uses as magneticsubstance rust-preventive agent; at surface and the rapid chelating of metal, the unit molecule complex compound protective membrane of one deck densification can be formed, effectively can suppress corrosion of metal.Material surface after this product treatment keeps primary colors, need not wash and can enter the next procedures such as application.Conventional epoxy anti-rust paint has epoxy iron red shop rust-inhibiting paint, Epoxy Aluminum rust-inhibiting paint, epoxystearic acid aluminium rust-inhibiting paint, epoxy iron red shop rust-inhibiting paint and epoxy zinc rich primer etc.
Rust-stabilising pigment is the important component part of rust-inhibiting paint. physics rust-stabilising pigment is the pigment that the chemical property of a class own is comparatively stable, they are the physicalies by itself, stable chemical performance, quality is hard, particle is trickle, excellent fillibility, improve the density of paint film, reduce the permeable of paint film thus play antirust effect. red iron oxide just belongs to this kind of material. and the rust-preventing characteristic of metallic aluminium powder is because aluminium powder has flaky texture, formation paint film is tight, also have the ability of stronger reflect UV linear light, paint film aging-resistant ability can be improved.Epoxy iron red shop, Epoxy Aluminum and epoxystearic acid aluminium rust-inhibiting paint red iron oxide are the rust-stabilising pigments that epoxy anti-rust paint is conventional, if add aluminium powder, then can strengthen its rustless property, epoxystearic acid aluminium rust-inhibiting paint containing aluminum stearate and red iron oxide rust-stabilising pigment, antirust except for steel surface, also may be used for the antirust of galvanized workpiece especially.Should be noted that and be, because aluminum stearate is slightly soluble in water, although so the rust-inhibiting paint rustless property containing aluminum stearate pigment is better than the rust-inhibiting paint only containing iron oxide red, it does not recommend long-term for underwater sites, otherwise can produce the problems such as foaming.
The main component of rust-inhibiting paint is rust-stabilising pigment and filmogen.Usually name with the title of rust-stabilising pigment, as: barium sulfate anticorrosive paint, iron oxide red anticorrosive paint etc.If divided with its rust inhibition, be broadly divided into four large classes: physical action anticorrosive paint, chemical action anticorrosive paint, electrochemical action anticorrosive paint, comprehensive action anticorrosive paint.Barium sulfate rust-inhibiting paint forms: by modified alkyd resin, rust-stabilising pigment, pigment extender, siccative, the compositions such as organic solvent.Characteristic: sticking power is good, and rustless property is high, water tolerance is strong, and seasoning is fast at normal temperatures.Some anticorrosive paints with trickle flakey material for main pigments.Physical action rust-stabilising pigment mainly contains: iron oxide red, natural iron oxide red, iron mica, aluminium powder, Graphite Powder 99 and trickle sheet glass etc.
Iron oxide red anticorrosive paint a kind ofly protects the chemistry of metallic surface from air, seawater etc. or the coating of galvanic corrosion.By modified alkyd resin, rust-stabilising pigment, pigment extender, siccative, the compositions such as organic solvent.Mainly be divided into physical property and the large class of chemically antirust paint two.The former leans on the suitable cooperation of pigment and paint vehicle, forms fine and close paint film to stop the intrusion of corrosives, as iron oxide red, aluminium powder, graphite rust-inhibiting paint etc.; The latter presses down rust effect, as red lead, zinc yellow anticorrosive paint etc. by the chemistry of rust-stabilising pigment.Antirust for metals such as bridge, boats and ships, pipelines.Sticking power is good, and rustless property is high, and water tolerance is strong, and seasoning is fast at normal temperatures.Be mainly used in mechanical means, steel construction, pipeline etc.
