FIELD: electricity.SUBSTANCE: fibre filler is impregnated with polymer base. A composite support module is moulded of the impregnated fibre filler. After holding an alumina coating is applied onto the hardened surface of the module. Epoxy-diane resin is used as the polymer base, aluminosilicate fibreglass is used as the fibre filler, and acryl-based alumina suspension with a fire-retarding agent is used as the alumina coating. A substance from the group of alumina tryhydrate, martinal, apyral, boehmite, ammonium polyphosphate or a synergetic mixture of at least two substances from the specified group is used as the fire-retarding agent. Also a mixture of melamine cyanurate with ammonium polyphosphate can be used as the fire-retarding agent.EFFECT: improving fire-resistance and increasing ignition temperature of the composite support module.4 cl |
