Description
Technical field
The present invention relates to technical field of aqueous paint, more particularly to a kind of quick-dry type waterborne metal anti-corrosive paint and its preparation
Method.
Background technology
With modern industry revolution wheel rolling forward, resource and environmental problem have turned into today's society sustainable development
A pair of principal contradictions.To adapt to the requirement of environmental protection and energy-conservation, the environment protecting water-based paint for developing low VOC develops as coating industry
Inexorable trend.
In the industry urgently exploitation quality is superior, easy construction environment-friendly water-based industrial coating, and waterborne metallic paint is even more water
Coating variety that is mostly important in property industrial coating, most being hoped for.In the waterborne metallic paint market for having obtained tentative application,
Water paint product mainly has alkyd water paint, polyurethane aqueous paint, acrylic compounds water paint, epoxy sort aqueous paint, fluorine carbon
Water paint etc..Alkyd water paint good brightness but hardness is not high, antiseptic property is poor.Polyurethane aqueous paint pliability is good, paint film synthesis
Excellent performance, but it is relatively costly.Acrylic acid aqueous paint hardness is good, has excellent weather resistance, but poor in flexibility, and antiseptic power is poor.Fluorine
Carbon water paint is weatherability coating type the most excellent, but physical and mechanical property is general, and expensive.Various types of
In waterborne metallic paint product, epoxy water paint is antiseptic property protrusion, excellent combination property, cost performance popular product high
Product, are widely used in the anti-corrosion protection of various different metal base materials.
However, the limitation by epoxy technologies in itself is influenceed, aqueous epoxy coating generally has two in use
Class drawback：1) epoxy coating of pot-life (up to 4 more than hour) more long, rate of drying is too slow；2) speed epoxy faster is done
Coating, pot-life is too short (being less than 2 hours).

Water of the present invention is preferably deionized water.
The mechanism of action to instant component is further described through below：
1. the present invention is creatively by water-base epoxy technology and aqueous acrylamide technic acid composite usage, realizes two kinds of technologies
Have complementary advantages, be obtained the excellent aqueous industrial coating product of antiseptic property, and assign new product with pot-life more long with it is very fast
Rate of drying.
Aqueous epoxy coating has superior anti-corrosion of metal performance, is particularly well-suited to moderate anti-corrosion and heavy antisepsis field.Water
Property epoxy coating be dual-component coating, i.e. component A and B component including being commonly called as in the industry.Come from existing domestic and international coating technology
See, component A is mostly with amine epoxy hardener as base-material, and B component is then main construct with epoxy resin latex.Application is applied
, it is necessary to component A is mixed with B component by certain weight ratio before work, and stir.As a rule, between A, B component
Reaction is more violent, and drying varniss speed is faster, and pot-life is naturally shorter.Conversely, the reaction between A, B component is slower, activation
Phase is more long, and drying varniss speed just accordingly slows down.
Water-borne acrylic coatings have rate of drying faster, and component is single, easy to operate, can be voluntarily under normal temperature condition
Drying and forming-film.Present invention research finds, water-based acrylic resin is compounded by a certain percentage with epoxy hardener, with obtained in it
Coating component A is used after mixing with B component, both can significantly extend pot-life, and can maintain drying and forming-film speed quickly.
