Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical magnetic red lead rust proof 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 red lead, zinc yellow anticorrosive paint etc. by the chemistry of rust-stabilising pigment.Antirust for metals such as bridge, boats and ships, pipelines.
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.The ferrous metal surface bottoming that alkyd red lead paint is mainly used in the ocean of slight and moderate corrosion and industrial environment is antirust, is not useable for portion under water.
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.
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.Lead red alcohol acid antirust paint is formed by Synolac, red lead powder, pigment extender, siccative, organic solvent mixed grinding.Lead red alcohol acid antirust paint good antirust property, fast drying, strong adhesion.
The main component of rust-inhibiting paint is rust-stabilising pigment and filmogen.Usually name with the title of rust-stabilising pigment, as: red lead 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.
