In the following, various aspects and various embodiments of the present invention will be described in more detail.

An aspect of the present invention relates to a thermoplastic elastomer composition comprising (A) an elastomeric film; And (B) an adhesive layer applied on the upper surface of the elastomeric membrane; Wherein said elastomeric membrane comprises a polymer comprising from 62.3 to 67.3% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), from 10 to 15% by weight of acetylatedonoline and from 22 to 23% subject; A first curing agent containing 62.3 to 67.3 wt% hydride terminated polydimethylsiloxane (CAS No.:70900-21-9), 10-15 wt% acetylatedonoline, and 22-23 wt% silicon dioxide; A first component comprising: And 70.1 to 75.1% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), 10-15% by weight of hydroxyethyl cellulose and 14-15% by weight of silicon dioxide; And 70 to 75.1% by weight of hydride terminated polydimethylsiloxane (CAS No.:70900-21-9), 10 to 15% by weight of hydroxyethyl cellulose, and 14 to 15% by weight of silicon dioxide ; And a second component comprising; The weight ratio of the first subject and the first curing agent is 1: 0.5-1; The weight ratio of the second subject and the second curing agent is 1: 0.5-1; Wherein the weight ratio of the first component to the second component is 1: 2-3; Wherein the adhesive layer comprises a third subject containing 90 to 99% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2) and 0.1 to 1.5% by weight of dipotassium glycyrrhizate; And 70 to 80% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), 10 to 20% by weight of hydride terminated polydimethylsiloxane (CAS No.:70900-21-9) and Methylhydroxysiloxane, dimethylsiloxane copolymer, and 1 to 10% by weight of trimethylsiloxane terminate (CAS NO .: 68037-59-2); The weight ratio of the third subject and the third curing agent is 1: 0.5-1; The thickness ratio of the elastomeric film and the adhesive layer is 1: 0.2-0.7; Wherein the elastomeric film comprises at least one pigment selected from hydrous iron oxide, ferrous oxide, ferric oxide and titanium oxide; Wherein the pigment comprises 0.5-30 parts by weight of the pigment relative to 100 parts by weight of the first subject and 0.5-30 parts by weight of the pigment relative to 100 parts by weight of the second subject. will be.

The artificial skin for dressing according to the present invention can solve the problem of the use limit of the conventional silicone pigment by dyeing a non-toxic elastic polymer with a non-toxic natural pigment of iron oxide and titanium dioxide. Further, there is an advantage that an adhesive layer is added on the non-toxic elastomer to easily adhere to and detach from the human body.

In addition, when the content of the pigment is less than the lower limit of the above range, the hiding power and dyeing power are considerably lowered, and when the upper limit of the above range is exceeded, the physical properties and appearance of the elastomer become poor.

In particular, although not explicitly described in the following examples or comparative examples, an elastomer is obtained by varying the weight ratio of the first component and the second component, and the ratio of the thickness of the obtained elastomer and the pressure- The storage stability (viscosity change) and durability (heat resistance, moisture resistance) were measured by making artificial skin.

As a result, unlike the other numerical ranges, the storage stability (viscosity change) and durability (heat resistance, moisture resistance, tear strength, and impact strength) , It was confirmed that it can be used for multi-use rather than single-use.

However, when one of the following conditions is not satisfied, the rate of change of viscosity is very large, and durability such as bubble or peeling is remarkably deteriorated.

(i) the weight ratio of the first component and the second component is 1: 2-3, (ii) the thickness ratio of the elastomeric film and the adhesive layer is 1: 0.2-0.7.

Another aspect of the present invention is a composition comprising: a) 62.3 to 67.3% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), 10 to 15% by weight of acetylatedisonine and 22 to 23% ≪ / RTI > And 0.5 to 30 parts by weight of pigment relative to 100 parts by weight of the first subject; (b) the filtered first mixture; And 62.3 to 67.3% by weight of hydride terminated polydimethylsiloxane (CAS No.:70900-21-9), 10 to 15% by weight of acetylatedonoline and 22 to 23% by weight of silicon dioxide, Mixing to obtain a first component; (c) a second subject containing 70.1 to 75.1% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), 10 to 15% by weight of acetylatedonoline and 14 to 15% by weight of silicon dioxide ; And 0.5 to 30 parts by weight of a pigment with respect to 100 parts by weight of the second subject; (d) the filtered second mixture; And 70 to 75.1% by weight of hydride terminated polydimethylsiloxane (CAS No.:70900-21-9), 10 to 15% by weight of acetylatedonoline and 14 to 15% by weight of silicon dioxide, Mixing to obtain a second component; (e) mixing the first component and the second component at a weight ratio of 1: 2-3 to form an elastomeric film by coating and then curing at room temperature for 2 to 5 hours; And (f) a third subject containing from 90 to 99% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2) and from 0.1 to 1.5% by weight of dipotassium glycyrrhizate; And 70 to 80% by weight of vinyl terminated polydimethylsiloxane (CAS No.: 68083-19-2), 10 to 20% by weight of hydride terminated polydimethylsiloxane (CAS No.:70900-21-9) and A pressure-sensitive adhesive mixture in which a third curing agent containing 1 to 10% by weight of methylhydroxylsiloxane, dimethylsiloxane copolymer, and trimethylsiloxane terminate (CAS NO .: 68037-59-2) was mixed at a weight ratio of 1: 0.5-1 Pouring and coating the top surface of the elastomeric film, followed by primary curing at 45 to 60 占 폚 for 40 to 80 seconds followed by secondary curing at room temperature for 30 to 50 minutes; Wherein the pigment is at least one selected from among hydrogenated iron oxide, ferrous oxide, ferric oxide and titanium oxide; The weight ratio of the first subject and the first curing agent is 1: 0.5-1; Wherein the weight ratio of the second subject and the second curing agent is 1: 0.5-1.

In the dyeing method for artificial skin for makeup, the pigment and the pigment are first mixed to allow the pigment to be well dispersed, followed by filtering, and then the hardener is mixed to prevent aggregation. On the other hand, when filtering was performed after mixing the pigment, the pigment and the curing agent at the same time, it was confirmed that the aggregation particles were generated and the dyeing power was considerably lowered.

In addition, it has been confirmed through the dyeing method according to the present invention that dyeing artificial skin for dressing with iron oxide and titanium oxide pigment has excellent color retention against light or heat.

Also, it has been confirmed that the dipotassium glycyrrhizate contained in the subject of the pressure-sensitive adhesive mixture plays a role of imparting flexibility by improving the tensile strength and elongation of the artificial skin for dressing according to the present invention.

In addition, it was confirmed that when either of the primary and secondary curing was not performed, residues were generated, film thickness retentivity was decreased, or film curling occurred.

Particularly, when the primary curing temperature is lower than 45 ° C or higher than 60 ° C, it is confirmed that the peeling strength is rapidly lowered.

The coating of step (e) and step (f) may be applied by any suitable technique such as bar coating, spin coating, brush coating, spray coating, dip coating, Die coating, roll-to-roll coating, and the like, but is not limited thereto.

In particular, when the coating method except for the bar coating is applied, the adhesive layer becomes very thin and it is difficult to have a uniform thickness, so that the bar coating method can be preferably performed.

Hereinafter, production examples and embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
