Description
Technical field
The present invention relates to a kind of metal surface heavy antisepsis additive and anti-decaying paint, more particularly to a kind of addition graphene
Galfan alloy additions and anti-decaying paint.
Background technology
Zinc rich paint has cathodic protection effect due to being rich in zinc powder, to steel substrate, therefore is preferred anti-corrosive primer.Zinc-rich
Priming paint is in terms of anticorrosion of steel structure, at present mainly by three important kinds：Epoxy zinc rich primer, alcohol-soluble zinc-rich coating and
Waterborne inorganic einc-rich primer.
Zinc rich primer is current corrosion of steel structure and most-often used one of the anti-corrosion primer in protection field, which has excellent
Long-effective corrosion performance and good mechanical performance, can be mating with a variety of upper coatings.Zinc-rich bottom on domestic and international market at present
Paint is all made of spherical zinc powder as filler, and the dosage of spherical zinc powder accounts for 60% or more of zinc-rich paint formula.How zinc-rich is reduced
The dosage and wear rate of zinc powder in priming paint, are the important research contents of anti-corrosion industry.
In zinc rich primer film, zinc primarily serves cathodic protection effect, must contain a large amount of zinc fine particles in dry film,
They must contact with each other and keep good contact that could form galvanic circle with base material.But high zinc powder in zinc rich primer
Content also brings along a series of problem.Main problem is：1 zinc content is high, and the compactness of paint film declines, and can influence coating
Water resistance, adhesive force and impact resistance etc..2, production, storage and transportation of the high zinc content to zinc rich primer in zinc rich primer
And construction etc. brings inconvenience.For metallic zinc when producing and preparing coating, stably dispersing is more difficult, during storage
It easy tos produce and serious sinks to the bottom phenomenon.3, the steel substrate containing zinc rich primer can be due to the height in priming paint in welding and cutting
Zinc content will produce a large amount of zinc fume, endanger the health of staff.
The inert graphene of sheet is New Two Dimensional nano material, has excellent electric conductivity, physical mechanical property and right
The shielding properties of hydrone, air.Using the superpower electric conductivity of graphene microchip and superhigh intensity and the cathode of zinc powder is combined to protect
Shield is applied to anticorrosive paint, and after construction solidification, the graphene in paint film mutually overlaps the " graphene+zinc-formed with zinc powder
Aluminium powder " conductive film, the conductive film generate synergistic effect, both may be used using the zinc powder in the good electric conductivity activation coating of graphene
Zinc powder dosage in paint film is greatly reduced, the content of zinc powder only has 30% or so in traditional zinc rich primer, and paint film can be improved
Cathodic protection acts on, and shows superior antiseptic property and matching performance.
Therefore, it is that traditional anticorrosive paint upgrades using graphene microchip new material as the anticorrosive paint of critical material
Product, be a significant technology innovation of anticorrosive paint, have boundless application space
Galfan alloy be the 1970s Centre De Recherches Metallurgiques of Belgium developed under the support of international lead zinc tissue
Coating alloy, be mainly Zn-Al- with its ingredient with hot dip（Rare-earth elements La+Ce）(mass fraction).Galfan alloys
With replacement coating the features such as its low melting point, good corrosion resistance and suitable for wire galvanization.
Galfan coated articles would generally be bent, knot in practical applications, and the craze of coating thus caused can serious shadow
The corrosion resistance for ringing coating, to influence the service life of product, Galfan coated articles are only applicable in and the hot dip of steel wire wire rod,
To the finished product of steel construction, hot dip can not be taken.
