Abstract
The present invention relates to a pearlescent white paint composition comprising a solids material and a film-former, said solids material comprising at least 90% w/w mica, 4-7% w/w TiO2 and 0.2-3.0% w/w particulate metallic Al. The relatively narrow combination of the three solids materials in the defined ratios provides highly desirable white pearlescent finishes at most advantageously relatively thin paint film thickness.
Description
Invention field
The present invention relates to white pearlescent coating, lacquer and priming paint; They are used for producing on the surface of painted or japanning the purposes of white " pearly-lustre " facing (finish) improving one's methods; Also relate to the substrate that obtains with described coating by described method, particularly car body.
Background of invention
In automotive industry, white (pearlescent white) facing of pearly-lustre is a kind of welcome and facing color of being praised very much for automobile and truck, more is subjected to human consumer's welcome because found the white facing of pearly-lustre than zero diopter white (flat white) facing.
By convention, in order to produce the white facing of pearly-lustre on vehicle, after the metal parts that exposes was smeared one or more primer coatings, it was necessary carrying out three step cladding processes.In order to produce the white facing of pearly-lustre, to apply a whitewash undercoat usually, then apply and contain micaceous pearlescent material coating usually, it is not colored, but the particle that contains the highly reflective material is to provide " pearly-lustre " facing; Apply Clear coating at last to seal following layer.Each coating must apply respectively, if must cure, must provide suitable time of drying before each succeeding layer applies.Therefore, the productive labor intensity of pearly-lustre facing is big, and consuming time.
No matter when two kinds of dissimilar paint coatings are coated on substrate, and compare between the multiple coating of coating of the same type, all must give the former long time of drying.In order to promote suitably solidifying of three coated coating facings, need time of drying and solidify each coating undercoat, pearicoat and Clear coating.By making the japanning vehicle on fabrication line, keep extra time to realize the time of drying of growing.Only make fabrication line pass through the japanning section of automobile assembling factory more slowly so that produce long time of drying between coating applies, this is infeasible.And whole fabrication line must prolong so that extra journey time to be provided between the coating dry epoch.Thus, in order to make the fabrication line time longer, just need a bigger actual factory floor space to move fabrication line.In the manufacturing works that real space is of great rarity, perhaps can not reserve between the coating that extra fabrication line length makes overbrushing material coating has the more time.Therefore, in some less manufacturing works, on the vehicle of manufacturing, perhaps can not provide some coating ornamental surface.
People's such as Jaffe United States Patent (USP) 5,871,827 whole theme is incorporated herein by reference, and the document discloses the method for two coatings and three coating automobile facings and their preparations, wherein by opaque light interfere pigment insertion Topcoating or inter coat are obtained multiple color.The method of Jaffe instruction relates to the use of two coatings, and wherein first coating contains opaque and white, black or coloured pigment obtaining whole the covering, and second coating is the coated interference pigment that can not hide first coating.Above colored film, also to apply transparent Topcoating to finish facing.The opaque coated interference pigment particle of being instructed is the multilayer particle with the opaque layer that applies with transparency dielectric layer, and they apply with semitransparent layer again.This is one and uses more complicated and expensive coating method, and the result of method has obtained the effect of polychrome coating.
People's such as Sada United States Patent (USP) 5,350,509 whole theme is incorporated herein by reference, the document discloses a kind of coating structure, it comprises coloured bottom, places first coating on the coloured bottom, contain transparent flash of light composition in first coating, every kind of flash of light composition comprises that the alternative stacked of at least two kinds of polymkeric substance, described two kinds of polymkeric substance have that different specific refractory poweres and control come the interference light of the reflection interference that free alternative stacked produces and is not the transmitted light of interference light.
The whole theme of the United States Patent (USP) 4,499,143 of Panush is incorporated herein by reference, and the document discloses a kind of transparent Topcoating composition, its contain be sealed in the mica particles, have a ferric oxide of low pigment ratio.The instruction of Panush is particularly related to and produces the colored finish with the degree of depth, transparency and colourity.Though this patent statement, the iron oxide pigment of mica sealing has the intrinsic opacifying power and has pearly-lustre, it is said that they have other color.Also statement, required color result can not obtain with metal such as aluminium and the former natural or synthetic dyestuff with pearly-lustre.These so-called " colourless and opaque " pigment have reduced the value of actual coloured pigment, cause gloomy low colourity color.Consider the concern for colored finish, this patent is not recognized and is instructed aluminium as the pigment in the white facing of pearly-lustre and the value of cover material.
The whole theme of the United States Patent (USP) 4,615,940 of Panush is incorporated herein by reference, and the document discloses utilizes the oyster white effect of overbrushing layer system to substrate, and wherein coloured substrate is coated on the surface, then applies the clear bottom coating, applies Clear coating then.This clear bottom coating should tend to have very poor covering performance and relative high transmittance.In order to compensate this specific character of undercoat, it is opacifying property to need priming paint to have a very effective black and white, and must take other measures to come the ultraviolet blocking-up level, otherwise, may significant electropaining layer degraded take place by the clear bottom coating just.In addition, the service requirements of clear bottom coating is primer coating layer and whole sand milling carefully, because the clear bottom coating can not be covered up the defective in the primer coating.
For conventional titanium dioxide white coating situation,, in paint medium, need the TiO 2 pigment of huge amount in order to obtain suitable opacifying power with rational film thickness (typically being the 30-50 micron).Such formulation for coating material has the ability of very little fixing more solid particulate, thereby does not almost have remaining space to add pearlescent material such as mica particle in coating compound.
Known, in the conventional white titania coating, add the visual appearance that mica can not change whitewash.Although there is pearlescent material, the conventional titania-based whitewash that has above the titanium content of pigment solids part 90%w/w still has " zero diopter " ultrawhite sight.
Solvent-based coating can carry 40-60%w/w pigment, and on the other hand, water-based paint and priming paint can not distribute pigment, have lower pigment load, such as the scope at 20-35%w/w.In all cases, for conventional white coating, 90% pigment must be white pigment, is generally titanium dioxide.Therefore, need mica sheet to be immersed in a large amount of TiO 2 pigments to make conventional white coating, like this, the micaceous pearlescent appearance can not with the naked eye be seen.
In order to make conventional white coating pearly-lustre facing, must suitably solidify the pearicoat of back coated mica or another kind of pearlescent material to stop " submergence " of pearlescent material, because conventional nacreous mica coating itself does not have opacifying power at white titanium dioxide.The covering characteristic of facing needs pigmented basecoat, so that the sand seal on the convering etc., and the true colors of generation painting products.Pearicoat only provides the luminous that " zero diopter " facing is changed into " pearly-lustre " facing.Because titanium dioxide white undercoat and pearicoat are two kinds of dissimilar coating, so every kind of coating all needs unique duration of light, so that before other material is coated on the surface, solidify each coating.If between the coating of pigmented basecoat and pearicoat coating, do not have duration of light, so will the starting the arc between the coating.The coating starting the arc is a kind of defect on paintwork, when dissolved and ooze out in the solvent of new coating material from the dyestuff of last dope layer or pigment, thereby when changing the facing color of new coating material, this defective just takes place.It is owing to when applying two kinds of dissimilar paint coatings, do not have sufficiently long duration of light to cause between the coating of two coatings.The coating of nacreous mica coating needs independent coating step separately, and this just requires the significant alteration of auto production line, thereby the coating cost that causes every car amount of manufacturing rolls up.
" opacifying power " is an important quantitative factor that definite coating constitutes.Opacifying power can be defined as quantitatively: coating hides fully by the performance of any background of its sprinkling.Generally speaking, acceptablely in the coatings industry be when the coating on being coated in black background has 0.98 the reflectance value that is coated in same thickness that white background coats, just to reach fully and hide.Therefore, opacifying power is the contrast coefficient of a background and paint thickness, and it need reduce to 0.02 with contrast difference.Standard digital 0.02 is received (Weber-Fechner) contrast rule based on weber-Fick, and the statement of this rule is imperceptible less than difference naked eyes for the people under medium lighting condition of 2% (0.02).
Opacifying power is by when coating is coated on painted surface, and the absorbing properties of the granules of pigments in the paint film produces.If produce a lot of light from the top on paint film surface, and substrate do not fog, and then the opacifying power of paint film is just poor.Most of pigment itself are crystalline.Particularly, when white pigment was dispersed in the paint medium, white pigment tended to scattered beam consumingly.If the single crystal growth of white pigment gets enough big, then it is considered to luminous, transparent glassy crystal.This light scattering characteristic causes a large amount of light to send from the paint film surface, and causes corresponding very poor opacifying power.
Titanium dioxide is the most frequently used white pigment in coating.Unfortunately, this pigment has relatively poor relatively opacifying power.In order to keep white, there is not a kind of coloured pigment (being defined as having big opacifying power) can improve the covering performance.Therefore, the conventional white undercoat is equipped with a large amount of TiO 2 pigments.Therefore, in order to obtain less than 35 micron thickness and whitewash color that have black and white covering performance, coating must contain 90%w/w titanium dioxide at least, and this approaches to allow in formulation for coating material coating to flow and is sprayed on lip-deep maximum pigment content effectively.By contrast, other painting color that comprises the pigment with more effective opacifying power also can comprise the pigment of about 5%w/w.
PCT/CA02/01810 disclose pigment, pigment formula, formulation for coating material and they at coated surface, particularly car body so that the purposes of white and color pearl facing to be provided.A described embodiment has the prescription in following solid ingredient scope, i.e. 0.1-15%TiO
2, 10-99% mica, 0.1-20% aluminium and 0-5% coloured pigment.
Though PCT/CA02/01810 has described the useful coating composition that the white facing of pearly-lustre is provided for substrate, but we surprisingly find a whitewash prescription that scope is very narrow, and this prescription provides an extremely good white facing of pearly-lustre that advantageously has thin film thickness with respect to two coatings of the prior art and three coating white pearlescent facings.
Therefore, though up to now, obtained major progress aspect improving one's methods providing, but still needed better coating composition, be used for improving the outward appearance and the coating method thereof of white pearlescent facing with the cost efficient manner for preparation white pearlescent coating ornamental surface and composition thereof.
Summary of the invention

Other preferred sheet form of micaceous also can successfully be used, and they can use separately, or and XIRALLIC
Product is used in combination.The mica ratio of different sheet form can be different, and this depends on required pigment performance and to the holding capacity of the manufacturing cost that increases, the manufacturing cost of described increase is from using preferred XIRALLIC
The increase ratio of product form.
Other pearl mica material can comprise the natural mica thin slice, and it has been coated with the metal oxides such as titanium dioxide or the ferric oxide of metal oxide such as aluminum oxide or high refractive index.
The membrane-forming agent that uses in the present composition can suitably be selected from those solvent base or water base materials of being used for usually known in the art in coating and paint formula.Preferably, membrane-forming agent is selected from those materials based on acrylic resin, urethane resin, vibrin or terpolycyantoamino-formaldehyde resin.Preferred acrylic resin is acrylamide, vinyl cyanide, methacrylic ester and ethylhexyl acrylate.
By the weight of the whole coating compositions that are coated on substrate, preferred compositions comprises about 7-8% acrylic resin, about 1% urethane resin, about 6% vibrin and about 5% terpolycyantoamino-formaldehyde resin.
Coating composition of the present invention can randomly also comprise one or more additives, and they are selected from ultraviolet protecting agent, extender, polymerizing catalyst, rheologic additive etc.
In order to oversimplify and knowing, in this manual, term " solid material " is meant solid-state material, i.e. TiO
2,, mica and Al.It does not comprise any original organic resin or the solid material that causes membrane-forming agent or is used for coating composition or coating material solidified above-mentioned solid additive.
On the other hand, the invention provides a kind of method that produces the white facing of pearly-lustre in substrate, this method is included in and applies a kind of pearly-lustre whitewash composition defined above in the described substrate; With the described composition of curing in described substrate.
