Description
Technical field
The invention belongs to antirust paint technical field, particularly relate to a kind of antiseptic and rustproof paint of water-base epoxy and preparation method thereof.
Background technology
Traditional solvent-borne antirusting paint is mainly with organic solvent as disperse medium.Therefore, can volatilize during preparation and use
Substantial amounts of organic compound i.e. Volatile Organic Composition (is called for short VOC).The volatilization of VOC to living environment and
The healthy of the mankind is all potential threat.On the other hand, jumping up occurs in the price of crude oil, and causes various places oiliness to be coated with
The price of material is forced constantly to promote, and its raw-material cost is also continuously increased.Therefore, scholars and research worker will researchs
Center of gravity is gradually turned to water paint by oil paint.
Water paint is the coating using water as solvent (or as disperse medium), have nontoxic, tasteless, cheap,
The features such as raw material resources is abundant, can greatly reduce the cost of raw material, and the pollution causing air；And can be greatly
Improve coating safety in storage, transport and work progress.
At present, abroad some companies are on polymer emulsion synthesizes, and use the self emulsifying technology of surfactant-free, i.e. use other
The polymer that specific polymerization technique makes multiple different monomers form is that layer structure is present in same micelle, thus reaches regulation
Vitrification point (Tg), it is ensured that the purpose of properties of product, makes product both have certain hardness, stain resistance, makes again construction easy
In carry out.It addition, improved the property of coating by prepared polymer emulsions such as stereospecfic polymerization, radiation polymerization, latex interpenetrating polymerizations
Energy and function.
And the developing direction of domestic water-based anticorrosive paint is mainly three below aspect: (1) waterborne zinc-rich primer: at the bottom of inorganic zinc-rich
Paint and epoxy zinc rich primer are one of long-acting priming paint, but it is solvent based coating.With the modified Portland of high mode as base material
Waterborne inorganic einc-rich primer be through practice test high-performance anticorrosion and antifouling coating, there is bigger development potentiality；(2) research and development
Organically-modified inorganic anti-corrosion material: in recent years, foreign applications organic emulsion modified concrete, to improve its intensity, media-resistant
Property, it is widely used in the application of industry ground slab, wherein epoxy aqueous emulsion is with fastest developing speed.Over nearly 10 years, have started to be applied to China
