DIORGANOPOLYSILOXANE/ACRYLIC ESTER COPOLYMER EMULSION COMPOSITION FOR TREATING FABRIC AND FABRIC TREATED WITH THE SAME

摘要

PURPOSE: To provide a diorganopolysiloxane/acrylic ester copolymer emulsion composition capable of forming a soft film having high flame retardancy and causing no cracking even at extremely low temperatures, by hardening at room temperature by removal of water, and to provide a highly flame-retardant fabric treated with the above emulsion composition. CONSTITUTION: This emulsion composition for treating fabrics is characterized by comprising (A) an emulsion of a copolymer made from (a-1) a diorganopolysiloxane having at least two silison atom-bound alkenyl groups in the molecule with the molecular chain ends blocked with hydroxyl groups and (a-2) an acrylic ester-based monomer, (B) colloidal silica, (C) a condensation reaction promotive catalyst, and (D) an inorganic flame retardant. The other objective fabric treated with the above emulsion composition is provided.
