ホスフィン酸塩の表面変性塩

Document Type and Number:

Japanese Patent JP4663222

Kind Code:

B2

Abstract:

Surface-modified salts of phosphinic and/or diphosphinic acids and/or polymers thereof (SMS) are modified with a surface coating of synthetic resin or wax. Surface-modified phosphinic acid and/or diphosphinic acid salts of formula (I) and/or (II) and/or their polymers (SMS), the salts or their polymers being coated with a surface layer of synthetic resin or wax. R1, R2 = 1-6C alkyl and/or aryl; R3 = 1-10C alkylene, 6-10C arylene, alkylarylene or arylalkylene; M = Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base; and m, n, x = 1-4. Independent claims are also included for: (1) a method for the production of SMS by adjusting an aqueous suspension of a phosphinate to pH 4-9, adding an aqueous emulsion of resin or wax or a solution of resin or wax in a water-miscible solvent, stirring for 0.5-3 hours at 40-80 degrees C, optionally adding an aqueous emulsion of an organic liquid and stirring for 0.5-3 hours at 20-90 degrees C to give a product in which 80-99.9 parts by weight (pts. wt.) phosphinate is coated with 0.1-20 wt.% resin/wax and optionally 0.1-5 wt.% stabilizer; (2) fireproofed plastic molding materials containing SMS; and (3) thermoplastic polymer moldings, film, thread and fibers containing SMS.
