Description
Technical field
The present invention relates to metallic paint corrosion-resistant field, more particularly to a kind of silane-modified water-base epoxy two-component zinc-rich paint and
Its preparation method.
Background technology
Zinc rich paint is due to rich in zinc powder, having cathodic protection effect to steel substrate, therefore be 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.
Epoxy zinc rich primer epoxy zinc rich primer is using epoxy resin as base-material, and super-fine zinc dust is main rust resisting pigment, epoxy
Zinc rich primer construction is more convenient than zinc-rich coating.There is fabulous cathodic protection to act on, fabulous antiseptic property, fast drying,
Adhesive force is strong, good Impact wear resistance, well gas cutting and weldability.With the steel adhesive force after blasting treatment
It is fabulous.It is primarily used to steel surface and protects anti-corrosion temporarily, also available for ship, bridge, offshore platform and steel construction antirust bottom
Paint.
At present, China's major part aqueous double-component epoxy zinc-rich product, deficiency that generally existing is water-fast, adhesive force is bad, salt
During mist adhesive force also can continuous decrease the problem of.The aqueous epoxy resins used for aqueous double-component of tracing it to its cause are to carry
The modified epoxy of polyether-modified segment, although such a modification by water-borne modification of epoxy resin, so as to prepare water-base epoxy
Two-component zinc-rich paint product, but its polyether-modified segment can greatly reduce the water resistance of film, especially hot and humid
Environment, this is also water-thinned epoxy zinc-rich coating products salt spray test possessed environment just, causes aqueous double-component epoxy rich
Zinc product loses adhesive force in salt spray test, and same phenomenon also occurs during the water-based cold cycling of re-test.This is such a production
One big problem of product, does not improve for many years.
In addition, the current system of aqueous double-component epoxy coating product is three kinds：1) solvent type resin is prepared by emulsifying
System；2) system of the aqueous epoxy resins as host；3) system of the waterborne curing agent as host.
In past more than ten years, Chinese aqueous double-component zinc-rich product, slower development, its main target is to replace
Solvent based product, so as to reduce VOC discharge.But its performance can not contrast with solvent based product all the time, and main performance is still
Water-fast deficiency, so as in the few achievements always of heavy antisepsis field.
Existing aqueous double-component epoxy zinc-enriched paint product mainly for product be：Engineering machinery shell, shipping collection
Vanning, high ferro locomotive, platform oil well, storage tank facility etc. are that market is extensive, and Difficulty reason just can not be with its performance
Solvent based product contends with
Aqueous double-component epoxy zinc-enriched paint product, although it is low to possess VOC content, construction close to solvent type feature,
Performance also needs to continue to strengthen.
For aqueous double-component epoxy zinc-enriched paint product, although it is low to possess VOC content, construction is close to solvent type spy
Point, but performance also needs to continue to strengthen, and the present invention provides a kind of silane-modified water-base epoxy two-component zinc-rich paint formula,
In view of drawbacks described above, creator of the present invention obtains this creation finally by prolonged research and practice.
The content of the invention
Problems to be solved by the invention
It is an object of the invention to a kind of silane-modified water-base epoxy two-component zinc-rich paint, to overcome above-mentioned technology to lack

Embodiment
Hereinafter, the embodiment of the present invention will be specifically described, it is necessary to illustrate, embodiment party of the invention
Formula is not limited to following explanation, therefore, illustrates also to be not construed as carrying out all enforceable forms of the present invention below
Limitation.In addition, unless there are specified otherwise, the organization appeared below is international unit title, for example, the content occurred
Unit or " % " unless specifically indicated, be weight percentage.
<First embodiment>
The first embodiment of the present invention provide firstly a kind of silane-modified water-base epoxy two-component zinc-rich paint combination
Thing.Described composition is made up of host and curing agent two-component.Contain the tree based on aqueous epoxy resins in the host
Fat composition.
Aqueous epoxy resins in the present invention can obtain according to chemic modified method, and chemic modified method is also known as self-emulsifying
Method, i.e., some hydrophilic groups are incorporated on epoxy molecule chain, or block or grafting, epoxy resin is derived from breast
The property of change, when this polymer-modified plus water is emulsified, hydrophobicity high-polymer molecular chain will be gathered into particulate, ion
Group or polar group are distributed in the surface of these particulates, due to mutually exclusive with like charges, as long as meeting necessarily
Dynamic conditions, so that it may form stable aqueous epoxy resin emulsion, this is the base that chemic modified method prepares aqueous epoxy resins
Present principles.The water-based ring prepared according to the difference of the hydrophilic radical property with surface-active action of introducing, chemic modified method
Oxygen tree fat liquor can be divided into three kinds of anionic, cationic and nonionic.
In some currently preferred embodiments, aqueous epoxy resins are selected from non-ion aqueous epoxy resin, special
It is not to be based on aqueous epoxy resins obtained from structure of bisphenol A, there is polyether segment to provide required hydrophily in its structure.

Methyldiethoxysilane ", epoxide group therein can be had with the abundant chain link reaction bonded of epoxy resin using the coupling agent
There are excellent paint adhesion, solvent resistance, salt fog resistance.
System is water-fast and the aqueous silane product of adhesive force present invention adds can significantly improve, such a silane product by
In possessing relatively good dispersion stability, so as to up to ensureing not separate out from system in year, in solidification process
In can rapidly raise with the volatilization of moisture and solvent, the concentration of silane, such a silane has relatively good wettability, and one
Fixed hydrophobic solvent, when water and solvent volatilize to a certain extent, the position of silane, which deadens, to be hindered and can disappear, wherein polar functional group meeting
With metallic substrate surface hydroxyl formed polymerize, the polar functional group of their own can also form auto polymerization, so can coating into
One layer of inorganic passivation film is formed before film in advance, its non-polar functional group can form second adsorption with resin, so as to which film is firm
Jail absorption is as a result exactly that resin more closely can be attached on base material, even if moisture is worn on the passivation film that silane is formed
Saturating epoxy zinc-rich film can not also penetrate the passivation film of siloxanes, even if penetrating, because silane passivation film conductivity is stronger,
The greatly sacrificed anticathode effect of increase zinc powder, it is very permanent so as to reach antiseptic property.So as to reach film it is long when
Between water-fast and relatively good adhesion performance.
