[0132] Therefore, the present invention provides a preparation method of a water-dispersed emulsion composition, comprising:
[0133] (1) a step of preparing a mixed solution containing the components (A) to (D);
[0134] (2) a step of adding the (E) component to the mixed solution to obtain a transparent or translucent emulsion composition α; and
[0135] (3) The step of further adding the said (E) component to the said emulsion composition (alpha), and obtaining the said water dispersion type emulsion composition.
[0136] In the case of the D-phase emulsification method, specifically, under the condition of shearing by a homodisperser, the mixture of the anionic surfactant of the component (A) and the polyol as the component (D) is gradually mixed. The organopolysiloxane of the (B) component and the (C) component is combined to form a D phase (that is, a mixed solution containing the (A) to (D) components is prepared (the above-mentioned step (1)). Then, slowly A predeter...

[0265] According to the compositions shown in Tables 2 to 3, (A) SFNa (KANEKASurfactin, KANEKA CORPORATION) as an anionic surfactant, and (B) an organopolysiloxane having at least two hydrosilyl groups in one molecule were prepared. The organopolysiloxanes (1) to (3) represented by the above formulae, and the organopolysiloxanes represented by the following formulas, which are organopolysiloxanes having at least two ethylenically unsaturated groups in one molecule of (C) Siloxanes (4) to (6), (D) glycerin which is a monohydric or polyhydric alcohol which is a polyhydric alcohol, and (H) decamethyl which is an oil agent other than the (B) and (C) components Cyclopentasiloxane (KF-995) or linear organopolysiloxane (KF-96A-6cs) (viscosity 20mm at 25°C) 2 Silicone oil containing no hydrosilyl group and ethylenically unsaturated group below / s), isododecane as a volatile hydrocarbon oil, and 2-ethylhexyl palmitate as an ester oil were charged into 200 mL of In a glass beaker, afte...

[0297] A 200 mL glass beaker containing 100 g of the emulsion compositions of Examples 12, 15 to 17, and 21 obtained above and having a milky white appearance was maintained at 20 to 25° C. on a stirring device, and in this state, chloroplatinum was added under stirring. Toluene solution of acid-vinylsiloxane complex (platinum concentration; 0.5 wt %) 0.1 g (5 ppm in platinum with respect to the total emulsion composition) and polyoxyethylene lauryl ether (ethylene oxide plus A mixture of 0.1 g of the number of moles = 9 mol) was stirred in the same temperature range as above for 12 hours, whereby the organopolysiloxane having a hydrosilyl group as the component (B) and the vinyl-containing organopolysiloxane as the component (C) were carried out. The addition-curing reaction of the organopolysiloxane produced an emulsion addition-curing composition (Table 6). It was confirmed by NMR measurement that all the peaks derived from the vinyl group disappeared, and it was confirmed ...
