High-dyeing-propertyalcohol alcohol acid paint vehicle
Technical field
The present invention relates to paint vehicle technical field, and in particular to a kind of High-dyeing-propertyalcohol alcohol acid paint vehicle.
Background technology
Alkyd paint alias alkyd resin coating or phthalic resin coating, are mainly made up of alkyd resin, are domestic at present raw
The maximum class coating of yield.It is plentiful hard, durable with cheap, simple, film less demanding to construction environment of constructing
Property and weatherability preferably, the advantages of ornamental and protectiveness is all relatively good.Alkyd paint is mainly used in general woodenware, furniture and family
The application of finishing, the application of common metal decoration, less demanding anti-corrosion of metal application, general agricultural machinery, automobile, instrument and meter, work
The aspects such as the application of industry equipment.Alkyd resin be with polyalcohol, polyacid and aliphatic acid as primary raw material, it is anti-by polycondensation
Should prepared by a kind of polymer because synthetic technology is ripe, raw material is easy to get, resin coating film good combination property, alkyd resin into
It is one of most wide kind of consumption maximum, purposes in synthetic resin.Alkyd paint includes solvent-borne alkyd paint and water-soluble alcohol acid paint
Two classes, traditional phthalic resin coating a large amount of solvents for solvent-borne type contains, main component be alkyd resin, No. 200 industrial napthas,
Drier anti skinning agent.Colored paint also contains pigment etc..The body of meeting serious harm environment and operating personnel during production and construction
Body health.In recent years, countries in the world environmental regulation is increasingly strict, and traditional solvent based coating is subject to increasing challenge.Apply
The Water-borne modification of material, high solid trend are increasingly apparent.Water soluble paint is to introduce hydrophilic or water in film forming polymer to increase
Molten group, become can be with water as dissolving medium a kind of coating, due to its advantage substantially, the water miscible research of coating should
Widely paid close attention to and achieve impressive progress with having caused.Water soluble alkyd resin coating is new development trend, is obtained
Substantial amounts of research and development.
The shortcoming of the paint vehicle that prior art is prepared is:Drying is not strong compared with slow, coloring, fineness is big and viscosity is small, uncomfortable
In the occasion of high-decoration.
The content of the invention

The present invention is modified using toluene di-isocyanate(TDI) to alkyd resin, synthesizes the alkyd tree containing urethane structure
Fat, it is formed by toluene di-isocyanate(TDI) substitution part phthalic anhydride with the monoglyceride reaction of vegetable oil, i.e., first by phthalic anhydride and plant
The monoglyceride of oil carries out esterification, and generation end group is the alkyd resin oligomer of-OH structures, is subsequently adding toluene two different
Cyanate, using the reaction of-OH and-NCO, toluene di-isocyanate(TDI) is introduced into Structure Detemination of Alkyd Resins.Realize to alkyd tree
Modified, the alkyd paint vehicle that modified alkyd resin is prepared for raw material of fat, has the advantages that high coloring, fast drying, Guar
Glue will not make the alkyd paint of preparation produce clustering phenomena as the raw material for preparing alkyd paint, improve manufacture and production operation
Convenience, it is ensured that the quality of alkyd paint, the adhesive force of alkyd paint can be strengthened as thickener from sodium carboxymethylcellulose,
Improve the coloring of alkyd paint.Drier can allow the moisture of alkyd paint to accelerate evaporation, shorten the drying time of alkyd paint.
