Abstract
Verfahren zur Flammschutz-Ausruestung von Baustoffen aus nachwachsenden Rohstoffen, bei dem der Baustoff mit einer waessrigen Impraegnierloesung, enthaltend 5 bis 20 Gew.-% Natrium- und/oder Kaliumcarbonat als Flammschutzmittel impraegniert wird.

 

WO 200000570 A UPAB: 20000218 NOVELTY - A flame and fungal resistant insulating material (I) comprises renewable raw materials containing 2-10 wt.% sodium-and/or potassium carbonate and 0.5-3 wt.% of a surfactant. (I) consists of hemp, miscanthus, flax jute or ramie chaff or fibers of hemp, miscanthus, flax, ramie or shorn wool. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a process for the production of (I) by impregnation with an aqueous solution (II) containing 5-20 wt.% sodium and/or potassium carbonate and 2-10 wt.% of a surfactant. USE - The impregnating solution (II) is useful for providing flame and fungal resistance to a renewable raw material based insulating material (I) (claimed). ADVANTAGE - The treated insulating material has improved flame and fungal resistance.
