A presente invenção refere-se a um método de aplicação de umpadrão a um substrato com o uso de tinta constituída de pigmentos magneti-camente orientáveis. A presente invenção refere-se ainda a produtos provi-dos com um padrão por meio de tal método.The present invention relates to a method of applying a pattern to a substrate using paint consisting of magnetically orientable pigments. The present invention further relates to products provided with a standard by such method.
A Patente EP 556 449 apresenta um método de decoração deum substrato com uma tinta contendo pigmentos de flocos magneticamenteorientáveis que formam um padrão com profundidade ótica sob a influênciade um campo magnético de um ímã, que tem um contorno correspondenteao padrão desejado. O ímã tem que permanecer no local até que o filme detinta fique seco. Durante a solidificação do filme de tinta, o ímã é impedidode se movimentar.EP 556 449 discloses a method of decorating a substrate with an ink containing magnetically orientable flake pigments which form an optical depth pattern under the influence of a magnetic field of a magnet, which has a contour corresponding to the desired pattern. The magnet must remain in place until the detecting film is dry. During solidification of the ink film, the magnet is prevented from moving.
A Patente FR 2113650 apresenta um método de decoração desubstratos com pigmentos de flocos magneticamente orientáveis, nos quaiso campo magnético que define o padrão desejado sobre o substrato é umacamada de primer contendo partículas magnéticas permanentes. Somenteos campos magnéticos relativamente fracos podem ser gerados pela finacamada de primer. Com a utilização de tais campos magnéticos fracos, édifícil se obter padrões com profundidade ótica.FR 2113650 discloses a method of decorating substrates with magnetically orientable flake pigments in which the magnetic field that defines the desired pattern on the substrate is a primer layer containing permanent magnetic particles. Only relatively weak magnetic fields can be generated by the primer finlayer. Using such weak magnetic fields, it is difficult to obtain patterns with optical depth.
A Publicação WO 02/090002 apresenta um método similar noqual o campo magnético é provido por meio de uma impressão magnéticasobre o substrato a ser pintado. Esse método é especialmente adequadopara documentos ou notas bancárias, porém menos adequado para substra-tos moldados, tais como peças de plástico.Publication WO 02/090002 discloses a similar method in which the magnetic field is provided by a magnetic impression on the substrate to be painted. This method is especially suited for documents or banknotes, but less suitable for molded substrates such as plastic parts.
O objetivo da invenção é o de encontrar uma forma de melhorara qualidade dos padrões decorativos sobre substratos de plástico, em espe-cial para melhorar a aparência de linhas bem-marcadas. Um outro objetivo éreduzir o tempo necessário para realizar o processo.The aim of the invention is to find a way to improve the quality of decorative patterns on plastic substrates, especially to enhance the appearance of well-marked lines. Another goal is to reduce the time required to complete the process.
O objetivo da presente invenção é alcançado através de um mé-todo para a decoração de um substrato de plástico por meio das seguintesetapas:- a aplicação de uma camada de tinta constituída de pigmentosmagneticamente orientáveis sobre o substrato;The object of the present invention is achieved by a method for decorating a plastic substrate by the following steps: applying a paint layer consisting of magnetically orientable pigments on the substrate;
- a exposição da tinta recém-aplicada, ainda não solidificada aum campo magnético, por meio do que os pigmentos são orientados ao Ion-go das linhas de campo do campo magnético a fim de produzir um padrãona camada de tinta; eexposing the freshly applied, yet solidified paint to a magnetic field whereby the pigments are oriented to the ion of the magnetic field field lines to produce a pattern on the paint layer; and
- a solidificação da tinta sobre o substrato;o método sendo caracterizado pelo fato de que o campo magné-tico é gerado por, pelo menos, uma peça magnética embutida ao substratode plástico a ser revestido, por exemplo, moldado no substrato de plástico.- the solidification of the paint on the substrate, the method being characterized by the fact that the magnetic field is generated by at least one magnetic piece embedded in the plastic substrate to be coated, for example, molded into the plastic substrate.
Em uma primeira modalidade, a peça magnética embutida aosubstrato é um ímã permanente tendo um contorno correspondente ao pa-drão desejado.In a first embodiment, the magnetic part embedded in the substrate is a permanent magnet having a contour corresponding to the desired pattern.
O ímã pode ser embutido no substrato, colocando o mesmo emum molde e moldando o plástico à sua volta, por exemplo, por meio de mol-dagem por injeção, moldagem por injeção de reação, moldagem com lamaou rotomoldagem, moldagem por imersão, moldagem de folha, moldagempor sopro, extrusão, pultrusão, ou qualquer outro método de produção ade-quado. Quanto menor a distância entre o ímã e a superfície do substrato aser revestida, mais claros serão os detalhes do padrão. Quanto menor a dis-tância entre o ímã embutido e a superfície de substrato, mais nítidos serãoos detalhes mostrados. Para se ter uma distância operacional combinadacom detalhes bem-definidos, o ímã pode, por exemplo, ser embutido cercade 1 a 1,5 mm abaixo da superfície do substrato.The magnet can be embedded in the substrate by placing it in a mold and molding the plastic around it, for example by injection molding, reaction injection molding, mud or rotational molding, dip molding, sheet, blow molding, extrusion, pultrusion, or any other suitable production method. The shorter the distance between the magnet and the surface of the coated substrate, the clearer the details of the pattern. The smaller the distance between the embedded magnet and the substrate surface, the sharper the details shown. To have a combined operating distance with well-defined details, the magnet can, for example, be embedded about 1 to 1.5 mm below the substrate surface.
Em uma modalidade alternativa, a peça magnética no substratoé formada por uma parte do substrato constituída de partículas magnéticasou magnetizáveis dispersas que tenham sido magnetizadas de modo a geraro campo magnético pretendido. Isso resulta em propriedades físicas e me-cânicas mais homogêneas.In an alternative embodiment, the magnetic part on the substrate is formed by a portion of the substrate consisting of magnetic or magnetizable dispersed particles that have been magnetized to generate the desired magnetic field. This results in more homogeneous physical and mechanical properties.
As partículas magnéticas podem, por exemplo, ser dispersas nosubstrato, misturando as mesmas com a matéria-prima antes da moldageme, posteriormente, moldando a mistura. Em seguida, as partículas podem sermagnetizadas de tal forma que possam gerar o desejado campo magnético.Magnetic particles may, for example, be dispersed in the substrate by mixing them with the raw material prior to molding and subsequently shaping the mixture. Then the particles can be magnetized so that they can generate the desired magnetic field.
Após a solidificação da camada de tinta, a peça magnética dosubstrato de plástico pode ser desmagnetizada, se assim for desejado. Istopode ser feito, por exemplo, usando-se uma força magnética semelhanteapós a cura ou secagem da tinta. Este processo não irá afetar a aparênciado padrão da camada de tinta, mas irá diminuir ou eliminar o campo magné-tico no produto final.After solidification of the paint layer, the magnetic part of the plastic substrate may be demagnetized if desired. This can be done, for example, using a similar magnetic force after curing or drying the paint. This process will not affect the default appearance of the paint layer, but will decrease or eliminate the magnetic field in the finished product.
As partículas magnéticas dispersas no substrato podem ser, porexemplo, partículas de ferrita, tais como a ferrita de bário ou a ferrita de es-trôncio, ligas de metais de terra rara, tais como as ligas de cobalto de samá-rio, o dióxido de cromo, o manganês de bismuto, o neodímio ou materiaismagnéticos similares. Normalmente, o tamanho de partículas das partículasmagnéticas pode variar de cerca de 10 micrometros até tanto quanto 20 nmou mais.Magnetic particles dispersed on the substrate may be, for example, ferrite particles such as barium ferrite or strontium ferrite, rare earth metal alloys such as samarium cobalt alloys, chromium, bismuth manganese, neodymium or similar magnetic materials. Typically, the particle size of the magnetic particles may range from about 10 micrometers to as much as 20 nm.
Opcionalmente, o substrato composto das partículas magnéticasou magnetizáveis dispersas pode ser produzido em duas ou mais fases, porexemplo, usando-se uma técnica de molde por dois tiros, na qual uma pri-meira parte constituída das partículas magnéticas ou magnetizáveis é injeta-da em primeiro lugar, seguida de um segundo tiro que pode ser sem as par-tículas magnéticas ou magnetizáveis, por exemplo, a fim de obter as propri-edades selecionadas ou benefícios de custo.Optionally, the substrate composed of the dispersed magnetic or magnetizable particles may be produced in two or more phases, for example, using a two-shot molding technique in which a first portion consisting of magnetic or magnetizable particles is injected into first, followed by a second shot that may be without magnetic or magnetizable particles, for example, in order to obtain the selected properties or cost benefits.
Após a moldagem ou formação do substrato constituído das par-tículas magnetizáveis, as partículas são magnetizadas em um padrão cor-respondente ao padrão a ser aplicado no filme de tinta. Isto pode ser feitopor meio do uso de um forte ímã permanente, por exemplo, baseado em li-gas de neodímio-ferro-boro, tais como o Ndi2Fei4B, ou um eletroímã. O ímãpode ter um contorno correspondente ao padrão desejado ou pode ser mo-vimentado ao longo de uma trajetória que delineia o padrão desejado.After molding or forming the substrate consisting of the magnetizable particles, the particles are magnetized in a pattern corresponding to the pattern to be applied to the paint film. This can be done by using a strong permanent magnet, for example based on neodymium iron boron bonds such as Ndi2Fei4B, or an electromagnet. The magnet may have an outline corresponding to the desired pattern or may be moved along a path that delineates the desired pattern.
O substrato pode, por exemplo, ser feito de qualquer termoplás-tico ou tipo de plástico termocurável, tais como o poli(cloreto de vinila), o po-liestireno, a acrilonitrila-butadieno-estireno (ABS), o policarbonato, a poliami-da, o poliuretano, o poliéster, o politetrafluoroetileno, os plásticos acrílicos,tais como o PMMA, as poliolefinas, por exemplo, o polietileno de alta densi-dade ou de média densidade, o polibuteno, ou o polipropileno, etc. As mistu-ras ou os híbridos adequados destes tipos de plástico podem também serutilizados, se assim for desejado. Alternativamente, o substrato pode ser fei-to de qualquer outro tipo de material formável ou fundível, tais como de ma-teriais cerâmicos ou de alumínio.The substrate may, for example, be made of any thermoplastic or heat-curable plastic type, such as polyvinyl chloride, polystyrene, acrylonitrile butadiene styrene (ABS), polycarbonate, polyiami polyurethane, polyester, polytetrafluoroethylene, acrylic plastics such as PMMA, polyolefins, for example high density or medium density polyethylene, polybutene, or polypropylene, etc. Suitable mixtures or hybrids of these types of plastics may also be used, if desired. Alternatively, the substrate may be made of any other formable or fusible material, such as ceramic or aluminum materials.
Opcionalmente, o substrato pode ser revestido com um primerantes de a tinta de efeito com as partículas magneticamente orientáveis seraplicada. Isto é especialmente adequado, no caso dos substratos de polia-mida ou de polipropileno.Optionally, the substrate may be coated with a primer and the effect paint with magnetically orientable particles will be applied. This is especially suitable for polyamide or polypropylene substrates.

Os pigmentospodem ter qualquer forma adequada, mas os flocos e as plaquetas revelampadrões mais claros. Os pigmentos magnéticos adequados são, por exem-pio, baseados em ferro, níquel, cobalto, cobre, prata, ouro, cromo, gadolínio,itérbio, disprósio, érbio, e similares, ou baseados em ligas, óxidos ou suasmisturas. Os flocos de ferrita são particularmente adequados. Os pigmentosem floco podem também ser pigmentos de múltiplas camadas, tendo pelomenos uma camada magnética e, opcionalmente, uma ou mais camadasnão-magnéticas. Os exemplos adequados são, por exemplo, a mica revesti-da com Fe2O3 ou a mica revestida com CoFe2O4. Um outro pigmento mag-nético adequado pode ser, por exemplo, a mica revestida com uma misturade polímero contendo oxido de ferro e cobalto e um oxido de cobalto. Alémdisso, pigmentos de flocos magnéticos reflexivos adequados podem ser u-sados para criar marcações tendo destaques ou contornos lustrosos. Demaneira alternativa, pigmentos de interferência, tais como os pigmentos demudança de cor, podem ser utilizados em uma ou em mais de uma camadade revestimento de tal forma que os pigmentos de interferência criem mar-cações que variam de cor e/ou variam de intensidade de cor quando vistos apartir de diferentes ângulos.Magnetically orientable pigments in paint can be made of magnetic or magnetizable material. Pigments may be of any suitable shape, but flakes and platelets reveal lighter patterns. Suitable magnetic pigments are, for example, based on iron, nickel, cobalt, copper, silver, gold, chromium, gadolinium, ytterbium, dysprosium, erbium, and the like, or based on alloys, oxides or mixtures thereof. Ferrite flakes are particularly suitable. Flake pigments may also be multi-layer pigments having at least one magnetic layer and optionally one or more non-magnetic layers. Suitable examples are, for example, Fe2O3-coated mica or CoFe2O4-coated mica. Another suitable magnetic pigment may be, for example, mica coated with a polymer mixture containing iron and cobalt oxide and a cobalt oxide. In addition, suitable reflective magnetic flake pigments may be used to create markings having glossy highlights or contours. Alternatively, interference pigments, such as color-changing pigments, may be used in one or more layers of coating such that interference pigments create markings that vary in color and / or vary in intensity. color when viewed from different angles.
Os materiais de pigmentos magnéticos doces adequados po-dem, por exemplo, ter uma coercividade de menos de cerca de 2000 Oe, porexemplo, de menos de cerca de 300 Oe. Os revestimentos constituídos detais materiais magnéticos doces não são magnéticos em resposta a metaisnão- magnetizados, tais como o aço, o latão ou o alumínio.Suitable sweet magnetic pigment materials may, for example, have a coercivity of less than about 2000 Oe, for example less than about 300 Oe. Coatings made of such sweet magnetic materials are not magnetic in response to non-magnetized metals such as steel, brass or aluminum.
Os flocos podem ter um tamanho de partícula médio de, por e-xemplo, 2 a 60 micrometros, por exemplo, de 10 a 30 micrômetros. A espes-sura de partícula média dos flocos pode ser, por exemplo, de 1 a 8 micrôme-tros.The flakes may have an average particle size of, for example, 2 to 60 micrometers, for example, 10 to 30 micrometers. The average particle thickness of the flakes may be, for example, from 1 to 8 micrometers.
