INORGANIC ANTI-DUSTING AGENT FOR ASBESTOS CAPABLE OF SAFELY REMOVING ASBESTOS-CONTAINING CONSTRUCTION MATERIALS

摘要

PURPOSE: An inorganic anti-dusting agent for asbestos is provided to ensure excellent fire refractoriness and heat resistance while not containing volatile organic chemicals, high solidifying property with asbestos, and excellent bond to asbestos.;CONSTITUTION: An inorganic anti-dusting agent for asbestos comprises an inorganic binder of an aluminosilicate skeleton, an aminoalkyltrialkoxysilane coupling agent, and water. Or the inorganic anti-dusting agent for asbestos comprises a reaction product bonded to silicon atoms of the coupling agent through oxygen atoms to aluminum atoms of the inorganic binder as a reaction product obtained by reacting the inorganic binder and the coupling agent in the presence of water. The inorganic anti-dusting agent for asbestos does not have volatile organic compounds with the proviso that the aminoalkyl group of the coupling agent is connected to the silicon atom by an Si-C bond and at least one amino group is positioned at the end of the aminoalkyl group opposite to carbon bonded to silicon atom.;COPYRIGHT KIPO 2011
