Abstract

Process is for pigmenting polyurethane or polyurea components in a black colour and is suitable esp. with prods. mfd. from recycled materials of the type mentioned. An organic black pigment is dissolved in a solvent, typically acetone and the component is dipped into the soln. before a final drying stage. Colouring is achieved by penetration of the soln. into the outer layer of the article. The black pigment used is typically 'Neozaponschwarz' (RTM). USE/ADVANTAGE - The process is used to colour polyurethane or polyurea components and is cheaper than processes using carbon black which also hinders fusion between granules.

Description

Die Erfindung betrifft ein Verfahren gemäß Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of Claim 1.

Normalerweise wird beim RIM-Verfahren dadurch schwarz eingefärbt, daß man der Polyolkomponente Schwarzpaste auf Rußbasis beimischt.Usually, the RIM process turns black, that black carbon black-based black paste is added to the polyol component.

Bei der Entwicklung des neuen Recycling-Verfahrens nach der Heißpreßmethode (P 40 00 472.4 und P 40 00 829.0) trat nun das Problem auf, daß die auf den Granulatkörnern haftenden Lackschichten zu einer marmorierten bzw. gescheckten, bunten Oberfläche der Recyclat-Artikel führten. Zugabe von Farbrußen oder Farbstoffen zum Granulat führte zu negativen Ergebnissen durch Behinderung des Zusammenschmelzens der Granulat-Partikel; ein erneutes Lackieren ist zu teuer.When developing the new recycling process after Hot pressing method (P 40 00 472.4 and P 40 00 829.0) now occurred the problem that the stick on the granules Lacquer layers to a marbled or pied, colorful Surface of the recycled items led. Addition of carbon black or dyes to the granules led to negative results by hindering the melting of the granulate particles; repainting is too expensive.

Mit dem erfindungsgemäßen Verfahren gemäß Kennzeichen des Anspruchs 1 ist es nun möglich, schwarz eingefärbte Recyclat- Artikel ohne größeren Kostenaufwand anzubieten.With the inventive method according to the characteristics of Claim 1, it is now possible to recycle black colored Offer articles at no major cost.

Zweckmäßigerweise wird Neozaponschwarz RE (Firma BASF), das in Aceton gelöst ist, eingesetzt. Die Lösung quillt dabei oberflächlich an, der Farbstoff verteilt sich in der äußeren Schicht der Oberfläche und färbt so den Artikel einheitlich schwarz.Expediently Neozaponschwarz RE (BASF), the is dissolved in acetone. The solution swells superficially, the dye is distributed in the outer Layer of the surface and thus colors the article uniformly black.
