Problems solved by technology

However, in the silicone rubber foam produced by this method, the opening degree of the foaming cells of the open-cell foam is very small, and there is almost no air permeability, so it is difficult to adjust the size of the openings, and the foaming is open. The film of the hole is formed very thin, so there is a problem of poor repeated deformation or low tear strength

Embodiment 1

[0077] Manufacture of Silicone Rubber Foam

[0078]70% by weight of dimethylpolysiloxane, 25% by weight of xylene, and 5% by weight of tourmaline were mixed to prepare a silicone rubber solution.

[0079] In addition, polyurethane foam (shinhwaurethane, Korea) was immersed in 10 liters of the above-prepared silicone rubber solution for 5 minutes.

[0080] The above-mentioned polyurethane foam impregnated with the silicone rubber solution was repeatedly supplied twice to a pressure roller (hallaclimate control Korea), and then passed through a conveyor belt dryer (JIN VIBRO TECH Korea) for 10 minutes for hot air drying to finally produce a silicone rubber foam .

Embodiment 2

[0082] Far-infrared radiation measurement of shoe soles made of silicone rubber foam

[0083] Utilize the silicon rubber foam that manufactures in above-mentioned embodiment 1, manufacture shoe sole, with infrared camera, under the condition of temperature 29 ℃, humidity 41%, measure the infrared radiation energy that above-mentioned shoe sole emits. On the other hand, a normal shoe sole was used as a comparative example. The respective measurement results are shown in Figure 1a with Figure 1b middle.

[0084] Such as Figure 1a with Figure 1b Shown, emit a large amount of infrared energy ( Figure 1a ), while in the comparative example it was confirmed that the emission of infrared energy was very small ( Figure 1b ).

Embodiment 3

[0086] Far Infrared Radiation Measurement of Bracelets Made of Silicone Rubber Foam

[0087] Adopt the silicon rubber foam that makes in above-mentioned embodiment 1, manufacture bracelet, wear above-mentioned bracelet 10 minutes later, utilize digital body temperature camera at 25 ℃, under the condition of relative humidity 40%, the body temperature change near the wrist of photographing. On the other hand, a wrist without a bracelet was used as a comparative example. The measurement results are shown in figure 2 .

[0088] Such as figure 2 As shown, the blood flow of the wrist wearing the bracelet made of silicone rubber foam of the present invention is promoted, and body temperature rises ( figure 2 on the left side of ), while in the comparative example, it was confirmed that the rise in body temperature was very small ( figure 2 to the right of the ).

[0089] In addition, blood samples were collected before wearing the above-mentioned bracelet and after 30 minut...

Abstract

Disclosed herein are a silicone sponge and preparation method and use thereof. More particularly, disclosed is a silicone sponge comprising a polyurethane sponge impregnated with a silicone solution, preparation method thereof and functional products made from the silicone sponge. The silicone sponge has excellent air permeability and elasticity, and various useful properties.

Description

technical field [0001] The present invention relates to a kind of silicone rubber foam and its manufacture method and application, relate to the silicone rubber foam characterized in that polyurethane foam is immersed in the silicone rubber solution and its manufacture method in detail, and the functional product. Background technique [0002] The basic substance of silicone rubber (silicone) is quartz, that is, silica or silicon dioxide (SiO 2 ), is the main component of common sand, and silicone rubber refers to a polymer formed by combining silicon with organic substances through silicon-oxygen (Si-O-Si) bonds. [0003] Silicone rubber foam manufactured using this type of silicone rubber is different from other foams in that it is very soft and has excellent heat resistance and cold resistance, so demand for it is increasing. Silicone rubber foam can be mixed with special raw materials to produce closed cell sponge and open cell sponge according to its foam structure, a...
