Description
Technical field
The present invention relates to a kind of technical field of paint preparation, more particularly to painting coating and its system in a kind of automobile water-based property
Preparation Method.
Background technology
Currently, common painting dressing automobiles need to follow the steps below：Pre-treatment, electrophoresis, middle painting (usual base coat), face
Apply and varnish.The coating that current painting dressing automobiles (particularly domestic auto vendor) are used is except pre-treatment and electrophoresis are basic
On outside Water-borne modification, other each road coatings are also all using solvent based coating as main flow.It is molten contained by solvent based coating
The substantial amounts of solvent discharge that agent is brought can cause serious environmental pollution.In every respect all when VOC emission is paid close attention to, vapour
Car coating certainly will need Water-borne modification.
Chinese patent CN1306055A, CN1306056A are used as matrix using saturated polyester resin and isocyanate resin
Invention has obtained that the water paint in auto parts and components can be used, but does not find that inventor says to the use in car body aspect
It is bright.And it is well known that the requirement to the coating of auto parts and components and the requirement to the coating of car body are different.Even
In similarly for the coating of car body, the requirement for car paint and the car paint of underbody suitable for roof is also
Different.
The auto vendor for having minority is had begun to using aqueous middle painting, but also develops slow.And solvent based coating
Compare, middle painting common problem aqueous at present also compares many：
1, price is higher
Because domestic aqueous developer resin is than later, import is also relied primarily on.For scribbling higher hitting property of stone in aqueous
The requirement of energy, typically just exacerbates the pressure in cost using aqueous isocyanates.
2, resistance to stone hits poor-performing
The market-oriented aqueous primer surfacer of contrast, resistance to stone hits performance and does not reach the standard of solvent based coating also (particularly
Composite coating).
3, baking temperature is higher
The aqueous middle baking temperature generally used that applies that the country is used is 150 DEG C, and this compares baking with solvent based coating
Temperature drift, this results in the raising of energy-output ratio.
In summary, it is aqueous that this area lacks that a kind of resistance to stone hits that performance is high, baking temperature is relatively low, cost is relatively low and environmentally friendly
Coating composition and automobile inter coat, therefore in the urgent need to resistance to stone is hit, performance is high, baking temperature is relatively low, cost is relatively low for this area
And the water-based paint compositions and its automobile inter coat of environmental protection.
The content of the invention
An object of the present invention is that providing resistance to stone hits performance height, the vapour that baking temperature is relatively low, cost is relatively low and environmentally friendly
Automobile-used aqueous middle painting coating.
The second object of the present invention is to provide the preparation method that coating is applied in a kind of automobile water-based property
Coating in the coating in the first aspect of the present invention is there is provided a kind of automobile water-based property, the automobile water-based property
Including following component：
In a preferred embodiment of the invention, the water-soluble polyester resin is selected from Bayhydrol D 270.
In a preferred embodiment of the invention, the emulsion-type polyester resin be selected from Bayhytherm 3146,
One kind in WatersolNP-5300, Setaqua 6071.
In a preferred embodiment of the invention, the aqueous epoxy resins are selected from the upper sea green good limited public affairs of water paint
Take charge of the water-soluble epoxy resin produced.
In a preferred embodiment of the invention, the methyl-etherified melamine amino resins be selected from Cymel-285-100,
Cymel-303、Cymel-301、Cymel-303LF、Cymel-303ULF、Cymel-350、Cymel-3745、Cymel-9370、

751st, Maprenal757, Maprenal 758, Maprenal MF900, Maprenal MF904, the and of Maprenal 745
One kind in Maprenal 747.
As the preparation method that coating is applied in the automobile water-based property of second aspect of the present invention, it is above-mentioned parts by weight, by water
It is dissolubility polyester resin, emulsion-type polyester resin, aqueous epoxy resins, talcum powder, calcium carbonate, barium sulfate, aqueous dispersion, aqueous
Levelling agent, aqueous wetting agent agent are added in homogenizer, with
1200-1600rmp rotating speed is stirred 1-3 hours, obtains mixture A；Aerosil is added into mixture
Anti-settling agent, methyl-etherified melamine amino resins, butyl glycol ether, 4-6 hours are stirred with 1800-2200rmp rotating speed, then,
With obtaining coating in automobile water-based property after the filter-cloth filtering of 200 mesh.
As a result of technical scheme as above, the present invention has excellent anti-stone impact property and impact strength, anti-stone
Impact property reaches more than 3 grades, and impact strength is 300Ncm, and the performance such as adhesive force, wet-heat resisting and salt spray resistance has reached molten
The standard of formulation Automotive Primer Surfacer.
