Title:
ALCOHOL-RESISTANT FOAM CONCENTRATE FOR QUENCHING
Document Type and Number:
Japanese Patent JPH09124884
Kind Code:
A
Abstract:

To produce an alcohol resistant foam concentrate containing a copolymer abundant in fluorine content in order to heighten a behavior of a foam concentrate in a polar liquid fire, conquering all of problems regarding to the use of polysaccharides.

This foam concentrate for alcohol resistant quenching not containing polysaccharides is composed of an aqueous dispersion solution including 0.5-10 weight % of at least one sort of water-insoluble copolymer fluoride prepared from at least one sort of monomer bearing a perfluoride side chain, at least one sort of monomer bearing an ionic or ionizable hydrophilic side chain and more than one sort of monomers having an arbitrary nonionic side chain, 1-20 weight % of at least one sort of hydrocarbon surfactant having a linear or branched alkyl radical bearing carbon atoms of 5-18, 0.5-10 weight % of at least one sort of fluorinated surfactant having surface tension of less than 25mN/m, preferably less than 20mN/m, at 20°C in an aqueous solution of 1g/L and 5-50 weight % of at least one sort of water-miscible organic solvent.
