Title: Improvements in or relating to flameproofing compositions
IPC: D06M13/292
Filed: 1955-01-17
Abstract: A flameproofing composition which may be incorporated into paint comprises a chlorinated organic material, containing at least 50 per cent by weight of chlorine, and at least 20 per cent by weight of an aryl or aryl substituted phosphate.  The chlorinated organic material preferably comprises a chlorinated aliphatic or cycloaliphatic compound containing more than eight carbon atoms, e.g. paraffin or other wax or oil, fats, and higher fatty acids and esters.  The aryl or aryl substituted phosphate may comprise tricresyl or triphenyl phosphate, or an alkenyl substituted dicresyl or diphenyl phosphate, the alkyl group having up to thirteen carbon atoms, e.g. diphenyl ethyl-hexyl phosphate.  The chlorinated organic material is stabilized against decomposition at normal temperatures by the addition of phenoxy propylene oxide, tolyl ethylene oxide, diphenyl ethylene oxide, diethyl ethylene oxide, benzyl ethylene oxide, epichlorhydrin, cyclopentene or cyclohexene glycide or an ether thereof such as the methyl-, ethyl-, propyl-, tolyl-, a - or b -naphthyl ether, an alkaline earth metal salt of an aliphatic acid such as strontium caprylate, tetra aryl or alkyl tin compounds in which the aryl or alkyl groups have from four to twelve carbon atoms, e.g. tetra-butyl tin.  The organic phosphate functions as a plasticiser, but the flameproofing composition may include an additional plasticiser such as dibutyl phthalate, and if the composition is to be injection moulded a lubricating material such as calcium stearate may be added.  The flameproofing composition preferably comprises 50 to 80 per cent by weight of chlorinated organic material.  In one of the described examples a flameproofed material is prepared by curing for 15 minutes at 225 DEG  F. a mixture comprising, in parts by weight, polyester resin 60, chlorinated paraffin wax 25, triphenyl phosphate 10, tertiary butyl benzoate 2, methyl ethyl ketone peroxide in dimethyl phthalate 1.6, and cobalt naphthenate 0.1.  Specifications 397,741, 652,669, [both in Group V], and U.S.A.  Specifications 2,333,639 and 2,445,553 are referred to.ALSO:A flameproofing composition comprises (1) a chlorinated organic material containing at least 50 per cent by weight of chlorine and (2) at least 20 per cent by weight of an aryl or aryl-substituted phosphate.  The composition may be incorporated into synthetic rubber, synthetic fibre fabrics and other synthetic resins such as polystyrene, polyethylene and methyl, ethyl, ispropyl, butyl and other methacrylates, and these may be in the unpolymerized, partially polymerized or completely polymerized state.  The composition may be incorporated also into cellulose derivatives such as cellulose acetate, propionate or butyrate or ethyl cellulose.  The chlorinated organic material preferably comprises a chlorinated aliphatic or cyclo-aliphatic compound containing more than eight carbon atoms, e.g. paraffin or other wax or an oil, fats or higher fatty acid or ester.  The aryl or aryl-substituted phosphate may comprise tricresyl or triphenyl phosphate, or an alkyl-substituted dicresyl or diphenyl phosphate, the alkyl group having up to thirteen carbon atoms, e.g. diphenyl ethyl-hexyl phosphate.  The chlorinated organic material is stabilized against decomposition at normal temperatures by the addition of phenoxy propylene oxide, tolyl ethylene oxide, diphenyl ethylene oxide, diethyl ethylene oxide, benzyl ethylene oxide, epichlorhydrin, cyclopentene or cyclohexene oxide, glycide or an ether thereof such as the methyl-, ethyl-, propyl-, tolyl-, a  or b  naphthyl ether, an alkaline earth metal salt of an aliphatic acid such as strontium caprylate, tetra aryl or alkyl tin compounds in which the aryl or alkyl groups have from four to twelve carbon atoms, e.g. tetra butyl, dibutyl diphenyl, or tetra phenyl tin and dibutyl tin dilaurate.  The organic phosphate functions as a plasticizer, but the flameproofing composition may include additional specified palsticizers such as dibutyl phthalate, and if the composition is to be injection moulded a lubricating material such as oleic or stearic acid or calcium stearate or oleate may be added.  Other optional ingredients are softening, antifoaming, lubricating and colouring materials and various specified U.V. light stabilizers.  Laminates comprising glass fibre mats may be made and those may be pre-sized with a more dilute polymer solution.  The flameproofing composition preferably comprises 50 to 80 per cent by weight of chlorinated organic material.  In examples flameproofed materials are prepared by curing mixtures comprising unsaturated polyester resins, chlorinated paraffin wax, triphenyl phosphate, benzoyl peroxide, tertiary butyl benzoate, methyl ethyl ketone peroxide in dimethyl phthalate, and cobalt and lead naphthenates.
