Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical waterproof rust proof paint and preparation method thereof.
Background technology
The chemistry of metallic surface from air, seawater etc. or the coating of galvanic corrosion can be protected.Coat the direct invasion that rust proof paint effectively can avoid various corrosives in air in metallic surface, make maximized prolongation metal time limit of service.Physical property and the large class of chemically antirust paint two can be divided into.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.Be applicable to kitchen, toilet, balcony, vault, pond, balcony swimming pool, the moistureproof and ground of warehouse, tunnel, timber floor warm up waterproof with the porcelain brick of various water regain and the stickup floor wall of cement basic layer and floor specialty WATER REPELLENT.
The rust-inhibiting paint used is roughly oily antirust varniss and aqueous antirust paint 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.Be applicable to the antirust of ferrous and nonferrous metals.
Select the powerful sequestrant myo-Inositol hexaphosphate of metal to be main component, 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.Be applicable to outdoor and have metal antirust under covering and indoor conditions.
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.Water-soluble, non-combustible, environmentally safe, use safety.
The main film forming substance of the clear lacquer is urethane resin, after it is applied to coated article surface, can react and film-forming with the moisture content in air, also can baking-curing film forming. this film has protection against the tide, Defend salt fog, anti-mildew NBC protective performance, and film transparency, luminance brightness is high, better apparent after being coated with, other rust-inhibiting paint rust-inhibiting paint kind also has a lot, as barium metaborate rust-inhibiting paint, zinc gray rust-inhibiting paint, epoxy anti-rust paint, iron mica rust-inhibiting paint, chlorinated polyvinyl chloride rust-inhibiting paint etc.
