| 摘要 |
The invention relates to a sizing agent for glass fibres used for insulation purposes, based on an epoxy resin of the water-dispersible glycidyl ether type, an amine hardener whose flashpoint is above 180 DEG C and additives (in amounts expressed as parts per 100 parts of dry resin), especially 0.1 to 2% of silane and 0 to 15% of a mineral oil, the epoxy resin preferably having a polymerisation index of less than 1 and the hardener having an NH equivalent molar mass of less than 100 g. …<??>The invention is applicable to the production of lightweight insulating products. |
