is an alkali metal, an ammonium base, or an organic amine base, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3. An aqueous solution or organic solvent solution of the emulsifier can be effectively used to emulsify a perfluoropolyether oil or a perfluorocarbon compound. The resulting emulsion exhibits excellent emulsification stability, and thus can be effectively used as a mold-releasing agent.
本发明涉及一种乳化剂,其作为活性成分包含以下通式所示的聚氟烷基膦酸盐:CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OM1)(OM2),其中M'是氢原子、碱金属、铵基或有机胺基,M2是碱金属、铵基或有机胺基,n为1至6的整数,a为1至4的整数,b为1至3的整数,c为1至3的整数。该乳化剂的水溶液或有机溶剂溶液可有效用于乳化全氟聚醚油或全氟碳化合物。由此产生的乳液表现出优异的乳化稳定性,因此可有效用作模具脱模剂。
