Embodiment 1

[0126] The silicone emulsion of the present invention ("emulsion A of the present invention") was prepared by a method comprising the following steps, wherein the amounts of each component were listed in Table 1.

[0127] 1. Add Component I and Component IV-1 to a reaction vessel and mix for 10 minutes under stirring at a speed of 500 rpm.

[0128] 2. With stirring at a speed of 500 rpm, add Component III, Component V-1, Component V-2, glacial acetic acid and 14.6 grams of water and mix for 15 minutes to form a homogeneous mixture.

[0129] 3. Add 128.6 grams of water and mix with stirring at 500 rpm for 30 minutes.

[0130] 4. After heating to a temperature of 70° C., add an aqueous solution consisting of 4 grams of component II and 12 grams of water, and heat at a temperature of 70° C. for 2 hours while stirring at a speed of 400 rpm.

[0131] 5. To the mixture cooled to room temperature was added an aqueous solution consisting of 0.6 g of acetic acid and 2.5 g of water. A...

Embodiment 2

[0134] With reference to the consumption of each component listed in Table 1, repeat the process of Example 1 to prepare another silicone emulsion of the present invention ("emulsion B of the present invention"), the difference is:

[0135] In step 1, component IV-1 is replaced by component IV-2,

[0136] ·Respectively change the amount of water added in step 2 and step 3 to 30 grams and 123.1 grams.

[0137] Obtain opaque white emulsion, its particle size is listed in Table 1.

Abstract

The invention relates to an organosilicon emulsion containing elastic body polyorganosiloxane with quaternary ammonium functionality and polydiorganosiloxane with a non-reactivity organic group. The organosilicon emulsion is obtained through the following method: in the presence of the polydiorganosiloxane with the non-reactivity organic group not reacting with other components (such as polyorganosiloxane with an amino group, an organic quaternary ammonium compound and a crosslinking agent) and a surfactant, the polyorganosiloxane with the amino group and the organic quaternary ammonium compound with an epoxy group or a halohydrin group react simultaneously, the crosslinking agent is used to crossly link the polyorganosiloxane with the amino group, and the components are dispersed in a polarity water phase. The organosilicon emulsion can be applied to various fields of textile fabrics, personnel nursing articles, and the like.

Description

technical field [0001] The present invention provides a novel silicone emulsion comprising elastic polysiloxanes with quaternary ammonium groups and polydiorganosiloxanes with non-reactive organic groups, which emulsion exhibits polydiorganosiloxane The synergistic effect of oxane emulsion and polysiloxane emulsion containing quaternary ammonium group. The present invention provides, inter alia, a silicone emulsion that is particularly suitable for use in personal care products that provide a superior feel. Background technique [0002] Silicone emulsions are widely used in various fields such as industry (textile, defoaming, processing, etc.), cosmetics, pharmaceuticals, etc., which are well known. [0003] Silicone emulsions are obtained by emulsifying silicones with mixing means such as stirrers, homogenizers, colloid mills, etc. in the presence of surfactants, or by subjecting cyclic siloxanes to emulsion polymerization. Silicone emulsions are available in oil-in-water...
