Description

"Verwendung von Zusammensetzungen als innere Antistatika für thermoplastische Kunststoffe""Use of compositions as internal antistatic agents for thermoplastics"
Gebiet der ErfindungField of the Invention
Die Erfindung betrifft die Verwendung von Zusammensetzungen auf Basis von Partialestern von Glycerin und/oder Polyglycerinen und Perchloraten als innere Antistatika für thermoplastische Kunststoffe.The invention relates to the use of compositions based on partial esters of glycerol and / or polyglycerols and perchlorates as internal antistatic agents for thermoplastics.
Stand der TechnikState of the art
Kunststoffe, beispielsweise Polyethylen, Polypropylen und PVC sind ausgesprochene Nichtleiter, also hochwertig elektrische Isolatoren. Diese Eigenschaft bewirkt, daß eine elektrische Aufladung der Oberfläche stattfindet und durch die damit verbundene Staubanziehung Formteile schnell verschmutzen und unansehnlich werden. Diese nachteiligen Eigenschaften lassen sich durch Antistatika weitgehend verhindern.Plastics, such as polyethylene, polypropylene and PVC are pronounced non-conductors, i.e. high-quality electrical insulators. This property causes the surface to be electrically charged and, due to the dust attraction associated with it, moldings quickly become dirty and unsightly. These disadvantageous properties can largely be prevented by antistatic agents.
Bei den Antistatika unterscheidet man äußere und innerer Antistatika. Äußere Antistatika sind Produkte, die auf Kunststoff-Formteile als dünne Schicht auf die Oberfläche aufgebracht werden. Der Nachteil dieses Oberflächenauftrages ist die geringe Beständigkeit des antistatischen Effektes, so daß die Schutzwirkung mit der Zeit nachläßt und vor allem nach einem Spülen und Waschen eine Nachbehandlung erforderlich ist. Innere Antistatika sind Bestandteil des Kunststoff-Compounds und werden zusammen mit anderen Additiven dem Kunststoff zugemischt. Der entscheidende Vorteil der inneren Antistatika ist der durch sie erzielbare Dauereffekt. Beschreibung der ErfindungIn the case of antistatic agents, a distinction is made between external and internal antistatic agents. External antistatic agents are products that are applied to plastic molded parts as a thin layer on the surface. The disadvantage of this surface application is the low resistance of the antistatic effect, so that the protective effect wears off over time and aftertreatment is necessary, especially after rinsing and washing. Internal antistatic agents are part of the plastic compound and are mixed with the plastic together with other additives. The decisive advantage of internal antistatic agents is the permanent effect they can achieve. Description of the invention

The rolled skins were produced by mixing the PVC powder and the additives mentioned and homogenizing and plasticizing them at 180 ° C. for 5 minutes on a laboratory rolling mill. Test pieces (test specimens) with the size of 10 × 10 cm were cut out from the approximately 0.5 mm thick rolled skins produced in this way.
Von den Prüfkörpern wurde der spezifische Oberflächenwiderstand nach DIN 53482 / VDE 0303 Teil 3 bestimmt. The specific surface resistance of the test specimens was determined in accordance with DIN 53482 / VDE 0303 Part 3.
