Beschrieben werden frühregenfeste Fugendichtungsmassen enthaltend - wäßrige Polymerdispersionen (I) - nicht-ionische Celluloseether (II) aus der von Hydroxyethyl-, Hydroxyethylmethyl-, Hydroxypropylmethyl und Hydroxypropylcellulose gebildeten Gruppe - Füllstoffe sowie - gegebenenfalls übliche Zusätze wie Pigmente, Weichmacher, Extender, Verdickungsmittel, Entschäumer, Dispergierhilfsmittel, pH-Regulatoren sowie Konservierungs- und Alterungsschutzmittel und herstellbar durch inniges Vermengen von (I) mit den übrigen Bestandteilen. Um (II) in Mengen einbringen zu können, die über der Löslichkeitsgrenze liegen, sind die Fugendichtungsmassen dadurch gekennzeichnet, daß (II) in retardierter Form abgemischt mit den Füllstoffen zugegeben und untergemischt wird.
摘要:
The present invention relates to a sealing compound based on polyvinyl chloride plastisols, which is characterized in that it comprises from 0.1 to 40 % by weight, based on the overall weight of the sealing compound, of one or more adhesives. The present invention relates additionally to processes for preparing the sealing compound, to processes for producing closures, especially for the pressure-tight closing of packaging containers, using this sealing compound, and to such closures.
摘要:
The subject of the present invention is a sealing compound which comprise A) from 20 to 95 % by weight of at least one compound having on average at least 2 isocyanate groups per molecule, the isocyanate groups each being blocked, B) from 1.5 to 30 % by weight of at least one di- and/or polyamine, C) from 0 to 50 % by weight of at least one further organic polymer, D) from 0 to 60 % by weight of pigments and/or fillers, E) from 0 to 50 % by weight of one or more reactive diluents, and F) from 0 to 35 % by weight of auxiliaries and additives, characterized in that the sealing compound comprises G) from 1 to 40 % by weight of at least one adhesive, the sum of the proportions by weight of all components A) to G) employed in the sealing compound being in each case 100 % by weight.
摘要:
An asbestos-free gasketing composition is disclosed, comprising (a) a rubber component, (b) a non-asbestos fiber, (c) an oil-absorbent agent, and (d) a filler. The gasket obtained from the composition has excellent oil sealing properties while exhibiting satisfactory strength.
