LAYER MATERIALS TREATED WITH DURABLE ACIDIC ODOR CONTROL/BINDER SYSTEMS

A thermoplastic layer material has at least one odor reducing surface which is treated with a carboxylic acid-based odor control agent, and which is able to withstand insults with an aqueous liquid. The acid-based odor control agent is bound to the layer material by an organosilicone polymer binder....

Beschreibung
Zusammenfassung:	A thermoplastic layer material has at least one odor reducing surface which is treated with a carboxylic acid-based odor control agent, and which is able to withstand insults with an aqueous liquid. The acid-based odor control agent is bound to the layer material by an organosilicone polymer binder. The binder is water-insoluble, andcan form a highly gas-permeable coating. The binder is also highly porous, so as to expose the odor control agent to ammonia and other odoriferous gases which it is intended to control. Cette invention se rapporte à un matériau en couches thermoplastique, qui comporte au moins une surface de réduction des odeurs traitée avec un agent désodorisant à base d'acide carboxylique et qui est capable de résister aux attaques d'un liquide aqueux. L'agent désodorisant à base d'acide est lié au matériau en couches au moyen d'un liant polymère d'organosilicone. Le liant est insoluble dans l'eau et il peut former un revêtement fortement perméable aux gaz. Le liant est également fortement poreux, afin d'exposer l'agent désodorisant à l'ammoniac et aux autres gaz odorifères qu'il est destiné à éliminer.
