Abstract

Plastics surfaces are treated by blasting with accelerated, energy-charged metal or mineral particles to improve the bond of subsequent lacquers, dyes or adhesives to the surface. The jetting or bombardment may modify the structure of the surface, the particles becoming integrated into the surface in addition to the electrostatic charging of the surface. The method is intended as a replacement of chemical-thermal treatment and cleansing of surfaces and is simpler, less time- consuming and less energy-consuming.

Description

Titel: Kunststoffoberflächen-Behandlung durch Strahlen mitTitle: Plastic surface treatment by blasting with

beschleunigter und energiegeladener Teilchen, als Basis für Kusntstoffoberflächen-Beschichtungen. Accelerated and energetic particles as a basis for plastic surface coatings.

Anwendungsgebiete sind die zur Beschichtung vorgesehenen Kusntstoffoberflächen.Areas of application are the plastic surfaces intended for coating.

Zweck ist es, Einsparung von Zeit und Material zur Beschichtun -vorbehandlung von Kunststof?oberflchen, bei hoher Haftung des Beschichtungsmaterials.The purpose is to save time and material for coating pretreatment of plastic surfaces, with high adhesion of the coating material.

Es ist bekannt, zur Erfüllung der Erfordernisse von Beschichtungen auf Kunststoffoberflächen, $die dem Werkstück anhaftenden Trennmittelrückstände mittels eier chemisch-thermischen Befreiung zu entfernen. Die zu beschichtende Oberfläche mit einem Haftvermittler zu behandeln, um eine Haftung zwischen Kunststoffoberflächen und Beschichtungsmaterialien zu erhalten.It is known to meet the needs of coatings on plastic surfaces, the release agent residues adhering to the workpiece to remove by means of egg chemical-thermal liberation. The surface to be coated Treat with an adhesion promoter to create an adhesion between plastic surfaces and to obtain coating materials.

Das zeitaufwendige Verfahrfl 1 zur Beseitigung der ittickstände von Trennmitteln durch chemisch-thermische Befreigung entspricht dem Stand der Technik. Durch die chemisch-thermische Behandlung zur Befreigung von Trennmittel entstehen h@@ Energi@k@s@@n, sowie Verbrauch von erdölabhängigen Produkten bei der Befreiung der Werkstücke vom Trennmittel, ebenso bei der Haftvermittlung zwischen Kusntstoffoberflächen und Beschichtungsmaterialien.The time-consuming Verfahrfl 1 to remove the tick status of Release agents by chemical-thermal release correspond to the state of the art. The chemical-thermal treatment for the release of release agents is created h @@ Energi @ k @ s @@ n, as well as consumption of petroleum-dependent products during the exemption the workpieces from the release agent, as well as the adhesion between plastic surfaces and coating materials.

Es ist die Aufgabe, den Zeit- und Energieverbrauch bei der Befreiung von Kusntstoffoberflächen von anhaftenden und diffundierten chemischen Mitteln, Trennm-itteln, zu reduzieren, ebenso den Verbrauch von sogenannten Haftvermittlern auf chemischer Basis zu reduzieren.It is the job of the time and energy consumed in liberation of plastic surfaces from adhering and diffused chemical agents, Release agents, as well as the consumption of so-called adhesion promoters on a chemical basis to reduce.

Als Lösung bietet sich die Behandlung der Kunststoffoberfläch mittels beschleunigter und energiegeladener Teilchen an.The solution is to treat the plastic surface by means of accelerated and energetic particles.

Die Anwendung von beschleunigten und energie geladenen Teilchen aus metallogischen und mineralogischen Stoffen deren Beschleunigung mittels AuSschleudern, oder geführtem Luftdruck erzielt wird, und steuerbar ist, ist die Ausgestaltung der Erfindung.The application of accelerated and energetic particles metallogical and mineralogical substances their acceleration by means of ejection, or guided air pressure is achieved, and is controllable, is the embodiment the invention.

rzielbare Vortc-ile sind die einfache technische und sichere Verhinderung der Haftverminderung von Beschichtungen, durch in und nuf der Oberfläche vorhandene Trennmittel; ebenso der Verzicht von Haftvermittlern zur Haftverbesserung von Beschichtungen auf Kunststoffoberflächen. Grundsätzliche Behandlungsmöglichkeit von Kunststoffen, die zur Beschichtung bisher nicht in Frage kamen. Achievable advantages are simple technical and safe prevention the reduction in adhesion of coatings due to those present in and near the surface Release agent; likewise the waiver of adhesion promoters to improve the adhesion of coatings on plastic surfaces. Basic treatment options for plastics, which were previously out of the question for coating.

insparungen von Produkten die in Abhängigkeit von Erdöl stehen, und benötigt wurden zur Beschichtungsvorbehandlung, ebenso die Zeit-insparung bei der Behandlung von Kunststoffoberflächen die zur Beschichtung vorgesehen werden. inspections of products that are dependent on petroleum, and were needed for the coating pretreatment, as well as the time savings for the Treatment of plastic surfaces that are intended for coating.

Die zur Beschlchtung vorgesehene Kunststoffoberfläche wird durch dit, handlung mit beschleunigten, energiegeladenen Teilchen von metallogischen n und mineralogischen Stoffen steuerbar gestrahlt, wobei kleinere Teilchen in die Oberfläche integriert werden.The plastic surface intended for coating is provided by dit, action with accelerated, energetic particles of metallogical n and mineralogical substances controllably blasted, with smaller particles in the surface to get integrated.

Durch die t;nergieabgabe der auftreffenden Teilchen auf der Kunststoffoberfläche, entstehen elektrische Ladungsträger, (Ionen, Elektronen) insbesondere der durch Reibung aufgeladenen, in die Kunststoffoberfläche integrierten Teilchen bewirken eine elektrische Aufladung der Kunststoffoberflächenschicht, in Abhängigkeit des Materials welches zum Strahlen Verwendung findet, und der durch Beschleunigung energiegeladener Teilchen. Durch das gesteuerte Strahlen entsteht in der Kunststoffoberflche eine Veränderung der Rauhtiefe, die je nach Kunststoffart und Beschichtungsmaterial geändert werden kann, durch Beschleunigung und Art der verwendeten Teilchen. Ebenfalls erhält die Kunststoffoberflächenschicht eine elektrostatische Aufladung, die mit der Rauhtiefe eine hohe Haftung von Beschichtungsmaterialien ergibt. Auf die in der Art behandelten Kunststoffoberflächen ist eine Auftragung von beliebigem Beschichtungswittel möglich.Due to the energy output of the impacting particles on the plastic surface, electrical charge carriers (ions, electrons) arise especially through Cause friction charged particles integrated into the plastic surface an electrical charge of the plastic surface layer, depending on the Material that is used for blasting, and that which is more energetic through acceleration Particle. The controlled blasting creates a in the plastic surface Change in surface roughness, which changes depending on the type of plastic and coating material can be, by acceleration and type of particles used. Also receives the plastic surface layer generates an electrostatic charge, which increases with the surface roughness results in high adhesion of coating materials. On those treated in the way Any coating agent can be applied to plastic surfaces.
