Vorzugsweise wird keramisches oder sehr schmelzbares Pulvermaterial mit einem Durchmesser zwischen 25 und 250 Mikron verwendet.Preferably ceramic or very fusible powder material with a diameter between 25 and 250 microns used.
Die Erfindung sieht ferner vor, daß als keramisches oder schwer schmelzbares Pulvermaterial ein Metalloxyd, ein Metallsilikat, Siliciumdioxyd, Porzellan oder Glas verwendet wird.The invention also provides that a ceramic or difficult to melt powder material Metal oxide, a metal silicate, silicon dioxide, porcelain or glass is used.
Gemäß einer Ausführungsform der Erfindung wird das Glas in Kugelform (Ballotini) verwendet, wobei die Glaskugeln einen Durchmesser zwischen 60 und 80 Mikron aufweisen. Ferner sieht die Erfindung die Aufbringung einer abdichtenden Schicht aus Epoxydharz auf die schlagfeste Schicht vor.According to one embodiment of the invention, the glass is used in spherical form (Ballotini), wherein the glass spheres are between 60 and 80 microns in diameter. The invention also provides Applying a sealing layer of epoxy resin to the impact-resistant layer.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, das erfindungsgemäße Verfahren zum Überziehen eines nichtmetallischen Körpers anzuwenden.According to a preferred development of the invention, the method according to the invention is provided to be used for coating a non-metallic body.
Die Verfestigung kann durch Wärme oder dadurch bewirkt werden, daß das Material bei normaler Umgebungstemperatur für eine bestimmte Zeit sich selbst überlassen wird.Solidification can be effected by heat or by leaving the material at normal ambient temperature is left to its own devices for a period of time.
Vorzugsweise ist das Kunstharz ein Epoxydharz, während der bevorzugte Stoff für die schlagfeste Schicht geschmolzenes Aluminiumoxyd ist. Fernei kann auf der schlagfesten Schicht eine Endschicht aus Kunstharz, z. B. einem Epoxydharz vorgesehen sein.The synthetic resin is preferably an epoxy resin, while the preferred material for the impact-resistant one Layer of molten aluminum oxide is. Furthermore, a final layer can be applied to the impact-resistant layer made of synthetic resin, e.g. B. an epoxy resin.
Die Größe der keramischen oder schwer schmelzbaren Teilchen ist nicht kritisch; ihr Durchmesser sollte jedoch nicht größer als 250 Mikron und nicht kleiner als 25 Mikron sein. Vorzugsweise werden Ballotini-Glaskugeln mit einem Durchmesser von 60 bis 80 Mikron verwendet.The size of the ceramic or refractory particles is not critical; their diameter however, it should be no larger than 250 microns and no smaller than 25 microns. Preferably be Ballotini glass balls with a diameter of 60 to 80 microns are used.
Im folgenden wird die Erfindung an Hand von Ausführungsbeispielen beschrieben.The invention is described below with reference to exemplary embodiments.
Eine den Grundkörper bildende Fiberglastafel wird vollständig gereinigt. Auf die gereinigte Oberfläche der Tafel wird dann eine Schicht aus Kunstharz aufgebracht. Das Kunstharz ist ein Epoxydharz, insbesondere ein flüssiges Harz. Das Harz wird in einer Dicke zwischen 0,05 und 0,2 mm und vorzugsweise von 0,13 mm aufgespritzt.A fiberglass sheet forming the base body is completely cleaned. On the cleaned surface A layer of synthetic resin is then applied to the board. The synthetic resin is an epoxy resin, especially a liquid resin. The resin is in a thickness between 0.05 and 0.2 mm and preferably 0.13 mm.
Nach der Auftragung und vor der Verfestigung wird eine Schicht von kleinen Glas-Ballotini mit einem Durchmesser zwischen 60 und 80 Mikron auf die Oberfläche des Harzes aufgebracht, wobei die Teilchen bis zu einer Höhe von zwei Dritteln des Durchmessers freigelegt bleiben.After application and before solidification, a layer of small glass ballotini is made with a diameter between 60 and 80 microns is applied to the surface of the resin, the Particles up to a height of two thirds of the diameter remain exposed.
Nachdem die Schicht aus Kunstharz getrocknet ist, wird sie durch Erhitzen der Tafel auf Temperaturen in dem Bereich zwischen 50 und 100° C verfestigt. Diese geringe Verfestigungstemperatur beeinträchtigt weder die physikalischen Eigenschaften der Tafel noch die der Glas-Ballotini; die Verfestigungszeit bei dieser Temperatur kann den Angaben des Harzherstellers entnommen werden.After the layer of synthetic resin has dried, it is made by heating the board to temperatures solidified in the range between 50 and 100 ° C. This low solidification temperature is detrimental neither the physical properties of the tablet nor those of the glass ballotini; the solidification time this temperature can be found in the information provided by the resin manufacturer.
Eine schlagfeste Schicht aus geschmolzenem Metalloxyd oder Mischungen von Siliciumdioxyd mit Metalloxyden wird dann auf die Oberfläche der freigelegten Teilchen der Schicht von Glas-Ballotini aufgebracht; diese haftet auf der Kunstharzschicht.An impact resistant layer of molten metal oxide or mixtures of silicon dioxide with Metal oxides are then applied to the surface of the exposed particles of the layer of glass ballotini; this adheres to the synthetic resin layer.
Die Schicht besteht zweckmäßigerweise aus geschmolzenem Aluminiumoxyd. Das bevorzugte Aufbringungsverfahren für diesen Überzug ist in der USA.-Patentschrift 2 707 691 beschrieben. Die schlagfeste Schicht ist zwischen 0,25 und 0.64 mm und vorzugsweise 0,38 mm dick.The layer expediently consists of molten aluminum oxide. The preferred method of application this coating is described in U.S. Patent No. 2,707,691. The impact-resistant layer is between 0.25 and 0.64 mm and preferably 0.38 mm thick.
Anschließend wird eine weitere Schicht aus Epoxydharz auf die schlagfeste Schicht aufgebracht und verfestigt. Diese Schicht ist zwischen 0,5 und 0,13 mm und vorzugsweise 0,076 mm dick. Auf diese Weise wird die sonst poröse Oberfläche der schlagfesten Schicht abgedichtet; diese zusätzliche Schicht ist nicht immer erforderlich.Then another layer of epoxy resin is applied to the impact-resistant layer and solidified. This layer is between 0.5 and 0.13 mm and preferably 0.076 mm thick. In this way, the otherwise porous surface becomes impact-resistant Layer sealed; this additional layer is not always required.
ίο Das Kunstharz enthält nach einer weiteren Ausführungsform kleine Glasteilchen und wird ohne die Aufbringung einer Schicht derartiger Teilchen verfestigt. Nach der Verfestigung wird die Oberfläche der Kunstharzschicht behandelt, um eine Schicht kleiner Glasteilchen freizulegen. Das weitere Verfahren verläuft dann wie oben beschrieben.ίο The synthetic resin contains according to a further embodiment small glass particles and is solidified without the application of a layer of such particles. After solidification, the surface of the synthetic resin layer is treated to form a layer to expose small glass particles. The rest of the procedure then proceeds as described above.
Die harte durch die abriebbeständige Schicht gebildete Oberfläche verringert (auch wenn sie mit Kunstharz überzogen ist) den Antrieb des Grundkörpers. Gleichzeitig haftet die Schicht auch bei hohen Geschwindigkeiten sicher an dem Grundkörper, während sie zur Untersuchung des Grundkörpers durch Behandlung mit einem harzabtragenden Mittel entfernbar gemacht werden kann.The hard surface formed by the abrasion-resistant layer is reduced (even if it is with Synthetic resin is coated) the drive of the base body. At the same time, the layer also adheres high speeds securely on the base body while they are examining the base body can be made removable by treatment with a resin-removing agent.
Statt Ballotini können auch noch andere Glasteilchen verwendet werden. Der Grundkörper kann aus Metall bestehen. Außer Glas können auch andere elektrisch nichtleitende keramische oder schwer schmelzbare Teilchen Verwendung finden, z. B. Teilchen aus Aluminiumoxyd oder Kaolin. Das kann z. B. dort vorteilhaft sein, wo hochfrequente Strahlungen auftreten, welche die Glasteilchen schmelzen würden. Die Erfindung findet insbesondere auf freiliegende Teile aus Kunstharz oder aus Leichtmetalllegierungen bei Flugzeugen Anwendung, welche durch Wasser-, Sand-, Stein- und andere Teilchen in der Luft der Gefahr einer Beschädigung ausgesetzt sind.Instead of Ballotini, other glass particles can also be used. The main body can made of metal. In addition to glass, other electrically non-conductive ceramic or heavy fusible particles find use, e.g. B. Particles of aluminum oxide or kaolin. That can z. B. be advantageous where high-frequency radiation occurs which melt the glass particles would. The invention applies in particular to exposed parts made of synthetic resin or light metal alloys in aircraft application, which is caused by water, sand, stone and other particles in the Air are exposed to the risk of damage.
Wenn der Grundkörper aus einem Nichtmetall,If the base body is made of a non-metal,
z. B. Fiberglas, und die schlagfeste Schicht ebenfalls aus einem Nichtmetall, z. B. aus geschmolzenem Aluminiumoxyd, besteht, führt das Verfahren zum Überziehen gemäß der Erfindung zu einem Schutzüberzug, der vollständig aus nichtmetallischen Stoffen besteht; dieser Überzug ist daher für Anwendungen geeignet, wo elektrische Transparenz, dielektrische oder nichtmagnetische Eigenschaften erfoiderlich sind.z. B. fiberglass, and the impact-resistant layer also made of a non-metal, e.g. B. from molten Aluminum oxide, the method of coating according to the invention leads to a protective coating, which consists entirely of non-metallic materials; this coating is therefore for applications suitable where electrical transparency, dielectric or non-magnetic properties are required are.
