Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical aluminium antirust 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 aluminium powder, aluminium powder, graphite rust-inhibiting paint etc.; The latter presses down rust effect, as pure water, zinc yellow anticorrosive paint etc. by the chemistry of rust-stabilising pigment.Antirust for metals such as bridge, boats and ships, pipelines.Pure water rust-inhibiting paint is the paint that a kind of pure water and siccative oil mix.Its perviousness, wettability are good, and paint film is soft, attachment is strong, but drying is slower.In addition because pure water 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 phosphoric acid 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 Aluminum rust-inhibiting paint, Epoxy Aluminum rust-inhibiting paint, epoxy Sodium chromate rust-inhibiting paint, Epoxy Aluminum 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. aluminum oxide powder 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 Aluminum, Epoxy Aluminum and epoxy Sodium chromate rust-inhibiting paint aluminum oxide powder are the rust-stabilising pigments that epoxy anti-rust paint is conventional, if add aluminium powder, then can strengthen its rustless property, epoxy Sodium chromate rust-inhibiting paint containing Sodium chromate and aluminum oxide powder 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 Sodium chromate is slightly soluble in water, although so the rust-inhibiting paint rustless property containing Sodium chromate pigment is better than the rust-inhibiting paint only containing aluminium powder, 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: pure water anticorrosive paint, aluminium powder 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.Pure water 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: aluminium powder, natural aluminium powder, iron mica, aluminium powder, Graphite Powder 99 and trickle sheet glass etc.Aluminium powder chlorinated rubber anti-rust paint is mainly applicable to the corrosion protection of hull bottom waterline, sluice, underwater steel construction, underground pipeline and other structures, is the good rust-inhibiting paint of a kind of shielding.
