Title:
製織又は不織繊維質基材を被覆するための水性シリコーンエマルジョン
Document Type and Number:
Japanese Patent JP4563173
Kind Code:
B2
Abstract:
Aqueous emulsion for impregnating (non)woven fibrous substrates comprises a polyaddition-crosslinkable polyorganosiloxane composition containing 0.005-10 wt.% of an adhesion promoter which is a protective hydrocolloid or a hydroxy- and ammonium-functional silane or polyorganosiloxane. Aqueous emulsion for impregnating (non)woven fibrous substrates contains a polyorganosiloxane (POS) with at least two silicon-bonded C2-C6 alkenyl group, a POS with at least three silicon-bonded hydrogen atoms, 0.005-10 wt.% of an adhesion promoter which is a protective hydrocolloid or a hydroxy- and ammonium-functional silane or POS, a catalyst, a surfactant, optionally a POS resin with at least two alkenyl groups, optionally a crosslinking inhibitor, optionally a pH-fixing agent, optionally one or more formulation aids and optionally a filler. When the adhesion promoter is a protective hydrocolloid, the emulsion must be prepared by mixing a catalyst-free pre-emulsion with a catalyst-containing pre-emulsion, at least one of which is prepared by mixing water, at least part of the silicone phase and at least part of the protective hydrocolloid. Independent claims are also included for: (1) production of the emulsion by charging a single reactor with all of the ingredients other than the catalyst, which is emulsified separately and added during preparation of the impregnation bath; (2) use of the emulsion for coating fibrous supports other than architectural textiles.
