High-dyeing-propertyalcohol alcohol acid paint vehicle
Technical field
The present invention relates to paint vehicle technical fields, and in particular to a kind of High-dyeing-propertyalcohol alcohol acid paint vehicle.
Background technique
Alkyd paint alias alkyd resin coating or phthalic resin coating, are mainly made of alkyd resin, are current domestic raw
The maximum a kind of coating of yield.With cheap, construction is simple, of less demanding to construction environment, film is plentiful hard, durable
The advantages that property and weatherability are preferable, decorative and protective all relatively good.Alkyd paint is mainly used for general woodenware, furniture and family
The coating of finishing, common metal decorate coating, anti-corrosion of metal coating of less demanding, general agricultural machinery, automobile, instrument and meter, work
The coating etc. of industry equipment.Alkyd resin be using polyalcohol, polyacid and fatty acid as primary raw material, it is anti-by polycondensation
Since synthetic technology is mature, raw material is easy to get, resin coating film good combination property, alkyd resin has become a kind of polymer prepared by answering
For one of the kind that dosage in synthetic resin is maximum, purposes is most wide.Alkyd paint includes solvent-borne alkyd paint and water-soluble alcohol acid paint
Two classes, traditional phthalic resin coating are that solvent type contains a large amount of solvents, main component be alkyd resin, No. 200 industrial napthas,
Drier anti skinning agent.Colored paint also contains pigment etc..Environment and the body of operator can be seriously endangered during production and construction
Body health.In recent years, countries in the world environmental regulation is increasingly strict, and traditional solvent based coating is by increasing challenge.It applies
Water-borne modification, the high solid trend of material are increasingly apparent.Water soluble paint is to introduce hydrophilic or water in film forming polymer to increase
Molten group, becoming can be using water as a kind of coating of dissolving medium, and since its advantage is obvious, the water-soluble research of coating is answered
It is widely paid close attention to having caused and achieves impressive progress.Water soluble alkyd resin coating is new development trend, is obtained
A large amount of research and development.
The shortcomings that paint vehicle that prior art preparation goes out, is: it is dry compared with slow, coloring is not strong, fineness is big and viscosity is small, it is uncomfortable
In the occasion of high-decoration.
Summary of the invention
In view of the above problems, the invention proposes a kind of High-dyeing-propertyalcohol alcohol acid paint vehicles, have high coloring, drying

Lower stirring 40-50min, can be obtained High-dyeing-propertyalcohol alcohol acid paint vehicle.
Preferably, the guar gum is cation guar gum.
Preferably, the surfactant selects benzalkonium bromide.
Preferably, the thickener selects sodium carboxymethylcellulose.
Preferably, the emulsifier selects Arabic gum.
Preferably, the drier selects aqueous polyurethane.
Using above-mentioned technical solution, the beneficial effect that the present invention reaches is:
The present invention is modified alkyd resin using toluene di-isocyanate(TDI), synthesizes the alkyd tree containing urethane structure
Rouge, it replaces part phthalic anhydride to react with the monoglyceride of vegetable oil by toluene di-isocyanate(TDI), i.e., first by phthalic anhydride and plant
The monoglyceride of oil carries out esterification, and generating end group is the-alkyd resin oligomer of OH structure, and it is different that toluene two is then added
Toluene di-isocyanate(TDI) is introduced into Structure Detemination of Alkyd Resins by cyanate using reacting for-OH and-NCO.It realizes to alkyd tree
The modification of rouge, modified alkyd resin are the alkyd paint vehicle of raw material preparation, have the advantages that high coloring, fast drying, Guar
Glue will not make the alkyd paint of preparation generate clustering phenomena, improve manufacture and production operation as the raw material for preparing alkyd paint
Convenience, it is ensured that the quality of alkyd paint selects sodium carboxymethylcellulose that the adhesive force of alkyd paint can be enhanced as thickener,
Improve the coloring of alkyd paint.Drier can allow the moisture of alkyd paint to accelerate evaporation, shorten the drying time of alkyd paint.
