There is a need for a material with moderate peelability that does not cause skin irritation or rash.

However, when such a medical adhesive tape is used as a biting prevention tape or a cutting tape, it is difficult to selectively or locally cover the portion where the biting or cutting occurs. It was necessary to wrap around the entire finger. However, if medical adhesive tape is wrapped around the entire finger in this way, when using a personal computer, mobile phone, etc., or when a beauty salon or the like is working, the finger may become uncomfortable or mistyped. The problem that it was easy to do was seen.

[0003] Therefore, liquid bandages mainly composed of a hydrophilic colloidal water-soluble high molecule, a liquid hydrocarbon compound, and a drug have been proposed as salve prevention ointments and cut ointments (for example, Patent Document 1).

In addition, as shown in FIG. 7, a film 104 provided with air holes 103 is coated with an adhesive, and the overall shape thereof is a circular part that is attached to each of the belly side and the back side of the finger. _The shape of the part with the constricted part 101 between 102 and the length of the part to be affixed to the abdomen and back of the finger is about the length from the fingertip to the front of the first joint. A fingernail covering tape 100 is proposed in which the minimum width of the part 101 is approximately the same as or slightly narrower than the width of the fingernail, and is provided with a non-adhesive knot part 106 corresponding to the position of the constricted part 101. (For example, see Patent Document 2).

[0015] [First embodiment]

The first embodiment includes at least a pressure-sensitive adhesive layer and a base material, and covers the surface side of the finger along the longitudinal direction of the finger or the force applied to cover the periphery of the fingernail. In this way, the adhesive protection member is a sticking protection member in which the planar shape of the adhesion protection member is approximately crescent, oval, circular, square, or polygonal. For example, as illustrated in FIGS. 1 (a) and 1 (b), it includes at least an adhesive layer 14 and a base material 12, and is used for adhesion protection so as to cover the periphery of the fingernail so as to cover the surface. This is a pressure-sensitive adhesive protective member 10 characterized in that it is a member (adhesive protective member for beetle) 10 and has a planar shape of a substantially crescent shape. Further, as exemplified in FIG. 1 (c), it is also preferable to have a configuration in which a reinforcing release member is laminated on the surface of the base material.

Therefore, as illustrated in FIGS. 2 (a) and 2 (b), the adhesive protection member 10 of the first embodiment is suitable for scab protection, and the finger is removed with the peeling member 16 removed. It is intended to be used by sticking so that the area around the nail 30 is covered. That is, it is used in a state where it covers a part of the side surface of the finger 31 but does not cover the back side of the finger 31 so that the finger does not feel strange.

Hereinafter, an embodiment of the adhesive protection member 10 of the first embodiment will be described mainly as an adhesion protection member for scabs.

[0017] 1. Substrate (1) Kind

Examples of the base material that constitutes a part of the adhesive protective member include, but are not limited to, polyurethane film, polyester film, chlorinated film, olefin film, polycarbonate film, polysulfone film, polyphenylene sulfide film, A polyimide film, paper, a film containing a fiber, etc. are mentioned.

Further, the form of the substrate is not particularly limited. For example, it may be a mesh-like material, or a woven or non-woven fabric.

For example, if a mesh-like material is used as a non-woven fabric, it can be used as an adhesive protective member for scabs that is extremely excellent in cushioning and air permeability. On the other hand, when a woven fabric made of polyester fiber or the like is used, the moisture permeability can be kept low, and the adhesive protection member for peas can be made excellent in followability to finger movement.

Therefore, it is preferable that the elongation rate of the base material (JIS-L-1096 compliant, the same shall apply hereinafter) is 400% or more because excellent usability is easily obtained. A value within the range is more preferable.

However, when using a base material that is difficult to handle due to its high elongation rate, a reinforcing release member 16 ′ should be laminated on the surface of the base material 12, as shown in FIG. 1 (c). Is preferred. By laminating the reinforcing release member in this way, it can be easily applied to a predetermined location, can selectively cover the portion where the bite or cut has occurred, and can also be used as a process paper at the time of manufacture. It is also possible to demonstrate the function.

In addition, the reinforcing peeling member exhibits a function as a reinforcing member in addition to the function as a peeling member. Therefore, the reinforcing peeling member includes a reinforcing material such as a fiber or an inorganic filler, or is thicker than a normal peeling member. It is preferable to increase the mechanical strength.

(2) Thickness

Further, it is preferable that the thickness of the base material to be applied is a value within the range of 5 to 2,000 m. The reason for this is that if the thickness of the base material to be applied is less than 5 m, the mechanical strength is lowered and may not be suitable for use as an adhesive protective member for scab.

On the other hand, if the thickness of the strong base material exceeds 2,000 m, it will become excessively thick and difficult to handle. This is because they may be peeled off. Therefore, it is more preferable to set the thickness of the base material to a value in the range of 10 to: L, OOO / zm, and it is more preferable to set a value in the range of 20-500 μm.

In particular, as described above, when the elongation percentage of the base material (based on JIS-L-1096) is 400% or more and the thickness of the base material is 10 to 30 / ζ πι, excellent usability is obtained. It can be said that it is easy to obtain.

However, when using a thin base material with such a high elongation rate, it can be easily applied to a predetermined location, and the portion where the bite or cut has occurred can be selectively covered or even easier. Therefore, it is preferable to laminate a reinforcing peeling member on the surface of the base material as described above.

(3) Shape

In addition, in order to cover the periphery of the fingernail so as to cover the surface of the fingernail or to cover the surface of the finger along the longitudinal direction of the finger, the planar shape of the adhesive protection member is approximately three. It is characterized by being a moon, ellipse, circle, square, or polygon. Then, in order to apply the cover around the fingernail so as to cover the surface of the fingernail, as shown in FIG. 1 (a), the planar shape of the base material 12 can be covered around the fingernail. In addition, it is more preferable to have a substantially crescent shape. That is, a force that is an example of a substantially crescent shape, as shown in FIG. 1 (a), an inner side surface 10a that is curved upward, and an outer side surface 10b that is substantially squarely arranged with the inner side surface 10a and is also curved upward. It has a right side surface 10c and a left side surface lOd showing a generally square shape. In addition, the distance (tl) between the inner side surface 10a and the outer side surface 10b arranged approximately square is a value of about 2 to 30 mm. Further, the distance (t2) between the inner side surface 10a and the outer side surface 10b on the right side surface 10c and the left side surface 10d is a value smaller than tl and a value of about 0.5 to 20 mm. Further, the distance (t3) between the tip of the right side surface 10c and the tip of the left side surface 10d is a value of about 5 to 25 mm.

The reason for this is that, by setting the planar shape of the base material to such a substantially crescent shape or the like, similarly, only the portion where the bite or cut occurs is covered along the periphery of the fingernail that is curved in a substantially crescent shape. Because it can. Therefore, it is possible to effectively protect the bite and cut without causing a sense of incongruity to the finger. In addition, such a planar shape, unlike a circular shape or a tape shape wound around a finger, reduces the movement of the finger, and even when using a personal computer, a mobile phone, etc. This is because the feeling of discomfort with respect to this becomes even less.

In addition, such a planar shape makes it easier to follow the movement of the finger, reduces the load on the adhesive layer, and does not easily peel off.

[0020] Further, regarding the planar shape of the base material 12, as shown in FIG. 3, an inner side surface 10a of a substantially crescent-shaped adhesive protection member 10 and an outer side surface 10b of another substantially crescent-shaped adhesive protection member 10 It is preferable to provide an engaging member 11 for engaging with each other. That is, even if the inner side surface 10a of the substantially crescent-shaped adhesive protection member 10 and the outer side surface 10b of another adjacent substantially crescent-shaped adhesive protection member 10 are partial, they are engaged and contacted as sides. It is preferable to have In the case of the adhesive protecting member 10 shown in FIG. 3, the flat portion located at the center of the inner side surface 10a and the outer side surface 10b is the engaging member 11 in this case.

The reason for this is that this configuration allows a plurality of adhesive protection members to be arranged without gaps, which is extremely advantageous in terms of space saving. Further, if a plurality of adhesive protection members can be arranged without gaps, the plurality of adhesive protection members can be formed by continuous cutting, which is advantageous in terms of the manufacturing process.

In addition, since a plurality of adhesive protection members can be used side by side according to the size of the finger and the size of the protection area against scabs and cuts, it is extremely advantageous in terms of use selection.

In the case of the adhesive protective member 10 shown in FIG. 3, the distance (t ′ 1) between the inner side surface 10a and the square-arranged outer side surface 10b is the inner side surface 10a of the right side surface 10c and the left side surface 10d, and The distance between the outer side surface 10b and the distance (2) is substantially equal to about 2 to 30 mm. Further, the distance (3) between the tip of the right side surface 10c and the tip of the left side surface 10d is a value of about 5 to 25 mm.

[0021] When a plurality of adhesive protection members are arranged side by side as described above, as shown in FIG. 3, the substantially crescent-shaped planar shape basically consists of straight portions, and the right side surface 10c and the left side surface More preferably, both 10d and the linear partial force are configured.

The reason for this is that a plurality of adhesive protection members can be used as long as all side surfaces are formed of straight portions. This is because the cutting accuracy is remarkably improved even when the material is continuously cut. In addition, since the side surfaces of adjacent substantially crescent-shaped adhesive protection members can be engaged and contacted as sides, a plurality of adhesive protection members are arranged more closely in the lateral direction, although not shown. It is because it can do.

[0022] Further, regarding the planar shape of the substrate 12, as shown in FIG. 4, it is preferable that flap portions 10e and 10f are provided on the side surface of the substantially crescent-shaped adhesive protection member 10.

This is because such an arrangement can reinforce the adhesive force and improve the ease of handling. Moreover, since the size of the flap portion can be changed according to the size of the finger and the size of the protective part of the scab, it is extremely useful for selection of use.

The shape of the flap portion is not particularly limited, but various shapes such as a semicircular shape, an oval shape, a rectangular shape, a square shape, a triangular shape, and a corrugated shape can be employed.

[0023] (4) Water-repellent treatment layer

Further, as shown in FIG. 5 (a), it is preferable to provide a water repellent treatment layer (including a sizing layer) 11 on the surface of the substrate 12.

The reason for this is that, in this way, it can be easily prevented from entering liquids from the outside even in water work, outside work, medical field, etc. This is because peeling can be effectively prevented.

In addition, it is preferable that such a water repellent layer also constitutes, for example, fluorine resin or silicone resin.

[0024] (5) Moisture permeability

Further, although depending on the use of the adhesive protective member, the moisture permeability of the substrate measured in accordance with JIS Z-0208 is preferably set to a value in the range of 100 to 900 gZm ² '24Hrs.

The reason for this is that by controlling the moisture permeability of the base material in this way, it is easy to prevent the entry of liquid substances from the outside even in the water work, the outside work, or the medical field, etc. This is not only preferable, but also because it can effectively prevent the adhesive protective member from peeling off.

Therefore, the moisture permeability of the substrate, to a value within the range of 150~800gZm ² '24Hrs More preferably, the value is more preferably in the range of 200 to 700 gZm ² ′ 24 Hrs. However, although some uses are restricted, as shown in Fig. 5 (b), when using non-woven fabric as the base material or when vent holes are provided in the base material, it conforms to JIS Z-0208 It is preferable that the water vapor permeability of the measured substrate is 1000 g / m ² · 24Hrs or more! /.

[0025] (6) Identification mark and decorative layer

Further, as shown in FIG. 5 (c), it is preferable that an identification mark corresponding to the type of the fingernail or a decorative layer 13 is provided on the surface of the base material 12.

The reason for this is that by providing a number mark, kanji mark, pictogram mark →, or braille mark as such a finger identification mark, the adhesive protection member 10 of the optimum size can be clearly identified. This is because the ease of use when using the adhesive protective member 10 can be remarkably improved.

In addition, by providing a decorative layer representing a number pattern, kanji pattern, pictogram pattern, photographic pattern, etc. as such a decorative layer 13, not only the usability when using the adhesive protective member 10 is improved, It is because the value about fashionability can also be improved. In particular, by using a decorative layer containing a fluorescent agent, it is also possible to enhance nighttime recognition.

[0026] 2. Adhesive layer

The type of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer is not particularly limited. For example, it is preferable to use an organopolysiloxane pressure-sensitive pressure-sensitive adhesive described below or an acrylic pressure-sensitive adhesive.

[0027] (1) Organopolysiloxane pressure-sensitive adhesive

In the present invention, it is preferable to use an organopolysiloxane pressure sensitive adhesive as a main component in the adhesive layer.

The reason for this is that the use of an organopolysiloxane pressure-sensitive adhesive can provide appropriate adhesion to the skin, while improving creep resistance, water resistance, and chemical resistance. It is because it can do.

As a typical example of such an organopolysiloxane pressure-sensitive adhesive, for example, a silicone resin having a structure represented by the general formula (1) or the general formula (2) is blended and dehydrated and condensed. Organopolysiloxane obtained by this is preferable.

[0032] Further, in the general formula (1), R ¹ and R ² are each a methyl group or a phenyl group. In order to impart heat resistance to the adhesive layer, The mole ratio of the phenyl group (methyl group Z phenol group) is preferably set to a value in the range of 25Z75 to 98Z2, more preferably in the range of 85/15 to 95/5. preferable.

Furthermore, in the general formula (1) and the general formula (2), n and m are usually in the range of 2000 to 200,000 cP of pressure-sensitive adhesive, considering the workability of forming an adhesive layer on the nonwoven fabric. It is preferable to adjust the value to be (25 ° C).

[0033] (2) Inorganic filler

It is preferable to add an inorganic filler in the range of 0.1 to 10% by weight based on the total amount in the organopolysiloxane pressure-sensitive adhesive.

The reason for this is that by adding an inorganic filler in such a range, the cohesive strength of the pressure-sensitive adhesive is improved, and the adhesive remains less glue when peeled off. In addition, the amount of the inorganic filler added is set to a value in the range of 1 to LO weight%, preferably in the range of 3 to 7 weight% with respect to the total amount.

The reason for this is that if the amount of the additive added is less than 1% by weight, the organopolysiloxane pressure-sensitive adhesive may remain on the skin as an adherend, and the added amount is less than 10% by weight. In such a case, the cohesive strength of the pressure-sensitive adhesive is excessively improved, and the pressure-sensitive adhesive strength may be significantly reduced.

Therefore, it is more preferable to add the inorganic filler in the range of 0.5 to 8% by weight, more preferably 1 to 5% by weight, based on the total amount.

Yes.

[0034] The average particle diameter of the inorganic filler contained in the organopolysiloxane-based pressure-sensitive adhesive is preferably 1 to 20 µm, preferably 4 to 12 µm.

This is because when the average particle size of the inorganic filler is less than 1 μm, the inorganic filler tends to aggregate and it is difficult to uniformly disperse it in the organopolysiloxane pressure sensitive adhesive. This is because there may be cases. In addition, when the average particle diameter of the inorganic filler exceeds 10 m, the thickness of the formed adhesive layer is usually 25 to 30 / ζ πι, so that the inorganic filler protrudes on the surface and becomes rough. This is because a feeling may be given. Furthermore, when the average particle size of the inorganic filler increases, the sedimentation rate of the inorganic filler in the organopolysiloxane pressure-sensitive adhesive increases in the manufacturing process, making it difficult to achieve a uniform dispersion state. This is because there are cases.

Specific examples of the inorganic filler include, for example, one kind of calcium carbonate, bentonite, titanium oxide, zinc oxide, carion, silica, or a combination of two or more kinds.

[0035] (3) Acrylic adhesive

It can also be added to the organopolysiloxane pressure sensitive adhesive (10-30% by weight of the total amount) or independently of the organopolysiloxane pressure sensitive adhesive (100% by weight of the total amount). It is preferable to use an adhesive.

This is because by using such an acrylic pressure-sensitive adhesive, tackiness can be easily improved without reducing the cohesive force of the pressure-sensitive adhesive. A typical example of such an acrylic pressure-sensitive adhesive is, for example, an acrylic copolymer mainly composed of 2-ethylhexyl acrylate and butyl acrylate.

In addition, the blending ratio of 2-ethylhexyl acrylate and butyl acrylate is adjusted to be 20:80 to 80:20, preferably 20:80 to 40:60 by weight. . This is because when the proportion of 2-ethylhexyl acrylate is excessively small, the cohesive strength of the adhesive increases and the adhesive strength may decrease. On the other hand, when the proportion of 2-ethylhexyl acrylate is excessively large, the cohesive force of the pressure-sensitive adhesive tends to be too low and the pressure-sensitive adhesive force tends to decrease.

In addition, as a monomer component constituting the acrylic pressure-sensitive adhesive, acrylamide or vinyl carboxylic acid may be blended within a range not exceeding 5% by weight with respect to the total amount.

Furthermore, considering the compatibility with the organopolysiloxane pressure-sensitive adhesive, the viscosity of the acrylic pressure-sensitive adhesive is preferably set to a value within the range of 500 to 20000 cP (25 ° C.).

[0036] (4) Crosslinking agent

In addition, in order to impart thermosetting properties to the organopolysiloxane pressure-sensitive adhesive and to improve the pressure-sensitive adhesive property at high temperatures, for example, organic peroxides such as peroxybenzoyl and peroxyditamyl and platinum catalysts are used. It is preferable to add in the range of 1.5 to 3% by weight based on the solid content of the organopolysiloxane adhesive.

In order to effectively exhibit the effect of addition, it is preferable to heat at a temperature of 120 ° C. or higher after adding an organic peroxide or a platinum catalyst.

[0037] (5) Additive

In addition, a preparation (drug) can be added to the pressure-sensitive adhesive composition as a kind of additive so as to exhibit a predetermined medicinal effect. The type of such a preparation is not particularly limited. For example, anti-inflammatory drugs, anti-inflammatory analgesics, coronary vasodilators, asthma drugs, antihypertensive drugs, antihistamines, tranquilizers, antibiotics, anesthetics In addition, one kind of vitamin preparation or a combination of two or more kinds can be mentioned.

The amount of the preparation added varies depending on the type of preparation and the application of the pressure-sensitive adhesive composition. For example, the value is within a range of 0.1 to 30% by mass with respect to the total amount of the pressure-sensitive adhesive composition. Can preferable.

[0038] It is preferable to add various additives to the pressure-sensitive adhesive composition. For example, one kind or two or more kinds of acid prevention agents, viscosity modifiers, ultraviolet absorbers, masking agents, plasticizers, waxes, colorants, inorganic fillers, organic fillers, extenders, coupling agents, etc. Combinations are listed.

[0039] 3. Peel adhesion

In addition, it is preferable to set the peel adhesive strength (mode: T-mode peel, adherend: stainless steel plate, peel speed: 300 mmZmin) of the adhesive protective member compliant with JIS Z0237 to a value within the range of 300 to 2000 gZ25 mm.

The reason for this is that if the strong peel adhesion is less than 300 gZ25 mmmm, it peels easily from the skin and the like, and may have a poor function as an adhesive protective member. On the other hand, if the strong peel adhesion exceeds 2000 g / 25 mm, it may be difficult to remove the adhesive from the skin, or the skin irritation may be excessively high, resulting in discomfort during use. Because there is.

Accordingly, it is more preferable to set the peel adhesive strength of the strong adhesive protection member to a value in the range of 500 to 1500 g / 25 mm, and it is more preferable to set the value in the range of 900 to 1200 g / 25 mm.

As shown in FIG. 6 (a), the pressure-sensitive adhesive layer 14 is formed on the peeling member 16. In this case, the method for forming the pressure-sensitive adhesive layer 14 is not particularly limited, but the pressure-sensitive adhesive composition is uniformly applied onto the substrate using, for example, a roll coater, comma coater, knife coater, or the like. Thus, it can be easily manufactured.

Further, depending on the type of the pressure-sensitive adhesive composition, it is also preferable to heat-treat under certain conditions in order to scatter the solvent or to perform a crosslinking treatment.

As mentioned above, if the elongation percentage of the base material (conforming to JIS-L-1096) is 400% or more, or if the thickness of the base material is 10-30 / ζ πι, Since it can be easily affixed to a predetermined location, and can be selectively covered or further easily manufactured, it can be easily manufactured as shown in Fig. 1 (c). It is preferable that a reinforcing release member 16 composed of a silicone release paper, a silicone release film, or the like is laminated on the surface in advance.

[0042] 2. Lamination process

As shown in FIG. 6 (a), the substrate 12 is further laminated on the pressure-sensitive adhesive layer 14 on the peeling member 16. In that case, the method of laminating the base material 12 is not particularly limited, but for example, a laminate, a press roll, or the like can be used.

[0043] 3. Cutting process

As shown in Fig. 6 (c), the laminate with the substrate 12 laminated using the cutting jig 20 is cut into a predetermined shape as shown in Fig. This is a process for forming the protective member 10. In that case, a cutter, knife, laser, cutting frame, etc. can be used as the cutting jig 20.

In consideration of subsequent handling, it is also preferable to cut only the base material 12 and the pressure-sensitive adhesive layer 14 into a predetermined shape without cutting the peeling member 16.
