FLAMEPROOFING AND FUNGICIDE AGENTS WHICH ARE BIOLOGICALLY SUITABLE FOR USE IN CONSTRUCTION, FOR INSULATING MATERIALS CONSISTING OF RENEWABLE RAW MATERIALS

摘要

The invention relates to a method for flameproofing insulating materials made with renewable raw materials. According to this method, the insulating material is impregnated with an aqueous impregnating solution containing 5 to 20 wt.% sodium and/or potassium carbonate as the flameproofing and fungicide agent and additionally, 2 to 10 wt.% of a tenside as a fungicide. The insulating materials are shavings of hemp, miscanthus, flax, jute and ramie and insulating matting consisting of fibres of hemp, miscanthus, flax, ramie and shorn wool.
