Embodiment 1

[0055] At room temperature, add polymelline silicone and hydrogenated lecithin at a quality ratio of 5: 1 to a high -pressure average mixer for 10 minutes at high speed 5000rpm to obtain a mixture. Keep the sediment; spray dry at 95 ° C temperature to obtain modified silicon elastic virtual; finally, the dry -drying silicon elastic body is crushed in a high -speed crusher with a speed of 3400rpm. Essence

Embodiment 2

[0057] At room temperature, add polybikes siliconane / polymels siliconane interconnection polymer to hydrogenated lecithin at a quality ratio of 2: 1 to a high -pressure average mixer and mix at high speed 10000rpm for 12min to get a mixture; Wash the mixture 3 times and centrifuge to keep the deployment of the lower layer of precipitation; spray dry at 100 ° C temperature to get modified silicon elastic virtual; finally, the dry -ditable silicon elastic body is at a high speed of 3800rpm in a high -speed crusher. Make crushing to obtain powder -like altering silicon elastic body and record weight.

Embodiment 3

[0059] At room temperature, add polybikes siliconane / polymels siliconane interconnection polymer to hydrogenated lecithin at 5: 1 to high -pressure average mixer to mix high -speed 10000rpm and mix for 15 minutes to get a mixture; Wash the mixture 3 times and centrifuge to keep the sediment; spray dry at 96 ° C temperature to get a modified silicon elastic body; finally, the dry -modified silicon elastic body is at a high speed of 3000rpm in a high -speed crusher. Make crushing to obtain powder -like altering silicon elastic body and record weight.

Abstract

The invention relates to a modified silicone elastomer and a preparation method thereof. The modified silicone elastomer comprises silicone elastomer powder and a lecithin modifier at least coating part of the surface of the silicone elastomer powder, and the mass ratio of the silicone elastomer powder to the lecithin modifier is (2: 1)-(10: 1). According to the preparation method disclosed by the invention, the silicon elastomer powder is coated and modified by using the lecithin modifier as a coating carrier, and the lecithin modifier is coated on part of the surface of the silicon elastomer powder, so that the unique physical and chemical properties of the silicon elastomer powder can be well retained in the coating manner; the modified silicone elastomer has moisture retention and water moistening property, and is not easy to dry; the lecithin modifier is extremely similar to a skin lipid structure, can easily permeate into the deep layer of the skin, improves the biocompatibility with the skin, does not generate the condition of mud rubbing, and has stronger covering power.

Description

Technical field [0001] This application involves the technical field of functional chemical materials, especially a modified silicon elastic body and its preparation method. Background technique [0002] In the field of cosmetics, silicon elastomers are usually cross -linking polymers of silicane or modified silicane three -dimensional mesh. Generally, there are three states: powder, gel, and emulsion. [0003] When the silicon elastic body is used in skin care products and makeup, it can play a role such as physical filling fine lines, regulating skin feel, oil control, and coking. Specifically, in terms of physical filling fine lines, the silicon elastic body in skin care products and makeup can be filled in fine lines, which has the effect of smoothing wrinkles visible to the naked eye; It has a feeling of Q bombs, which is easy to apply and uses a good sense of use; in terms of oil control, the silicon elastic body of the cross -network structure can lock the fat in the three...
