The first sheet layer 410 may be made of an inorganic elastic waterproof material, thereby improving weather resistance, corrosion resistance, durability, etc. of the waterproof sheet 420. The inorganic elastic waterproofing material is composed of a special copolymerized emulsion and a cement-based special combination aggregate as a main component. For example, an emulsion of STYRENE-BUTYL ACRYLATE COPOLYMER and a cement powder (for example, Lent cement, alumina, silica sand, defoamer, water reducing agent, etc.) or by adding water thereto.

The waterproof sheet 420 may be disposed on the first sheet layer 410 and function as a secondary waterproof layer. The waterproof sheet 420 is made of metal such as iron, aluminum, stainless steel, or chrome, and is formed of a thin plate panel, and protects the first sheet layer 410 on the lower side and can cope with an external impact. Particularly, the waterproof sheets 420 are composed of a plurality of waterproof sheets 420 and can be disposed continuously on the first sheet layer 410. At this time, the magnetic joint layer 430 is disposed at the joint between the waterproof sheets 420 to correspond to the stress behavior of the waterproof sheet 420 and to maintain airtightness.

Particularly, even if the soft cushioning portion 460 is contracted / expanded by the waterproof sheet 420, the airtightness can be continuously maintained by the magnetic joint layer 430 attached at the upper and lower ends of the cushioning portion 460 .

 The adhesive composition (not shown) is applied to at least one region of the construction of the protector 400 to form a first sheet layer 410, a waterproof sheet 420, a magnetic joint layer 430, a second sheet layer 440, At least one of the buffer 450 and the buffer 460 can be stably fixedly coupled. The adhesive composition according to an embodiment of the present invention comprises 40 to 80 parts by weight of a thermoplastic resin, 5 to 40 parts by weight of a tackifier resin, 1 to 5 parts by weight of a pine resin, 1 to 10 parts by weight of a plasticizer, 1 to 10 parts by weight of a filler, 0.1 to 1 part by weight of an antioxidant. The present invention relates to a hot-melt adhesive composition, which is generally manufactured in a state of being adhered between a releasing agent and a silicone band, removes a releasing agent when applied to a fabric, and performs a pressing operation so as to adhere a silicone band to the fabric. Hereinafter, each component will be described in detail.

The thermoplastic resin is a main component of the composition and has a function of controlling the adhesive force and the cohesive force. Vinyl acetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, polyurethane, and the like, as long as it contains a vinyl group or a hydroxyl group. Or a combination thereof.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight based on the total composition. When the content is less than 40 parts by weight, the melt viscosity is increased and the melt flow index is lowered, and the workability is very poor. When the content is more than 80 parts by weight, it is difficult to exhibit sufficient adhesive force to be immediately applied to the fabric.

The tackifier resin is a low-molecular-weight resin, which improves workability by lowering the melt viscosity, improves the initial wettability of the adhesive and the adhesive force of the adhesive on the surface of the adherend, and makes it possible to control the solidification time.

The type of the tackifier resin is not particularly limited, but it is preferably a petroleum resin. More specifically, the tackifier resin may be composed of at least one selected from the group consisting of an aliphatic hydrocarbon resin, an alicyclic hydrocarbon resin, an aromatic hydrocarbon resin, an aromatic modified aliphatic hydrocarbon resin, and a hydrogenated hydrocarbon resin.

The aliphatic hydrocarbon resin is a commercial product such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, and Hikorez R-1100S of Kolon Oil & Examples of the alicyclic hydrocarbon resin include a hydrocarbon resin containing dicyclopentadiene (DCPD) as a monomer. The aromatic hydrocarbon resin is commercially available as Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, There are Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000 and Hirenol PL-400. The aromatic-modified aliphatic hydrocarbon resin is commercially available from Hikorez T-1080, Hikorez T-1100 and the like manufactured by Kolon Oil & Hydrogenated hydrocarbon resins can be further classified into hydrogensified aliphatic hydrocarbon resins, hydrogenated aromatic hydrocarbon resins and the like, commercially available from Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130, and Sukorez SU-90.

The tackifier resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer. Specifically, a C5 aliphatic resin, a C9 aromatic resin, a C5 / C9 aliphatic / aromatic copolymer resin and the like can be used.

Further, the tackifier resin of the present invention is more preferably a hydrocarbonated hydrocarbon resin containing dicyclopentadiene as a monomer, commercially available from Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130, and Sukorez SU-90.

Meanwhile, the adhesive composition of the present invention is preferably applied to parts directly contacting the skin, so that the biodegradable low irritant resin is preferably mixed with the various petroleum resins described above in order to minimize irritation.

The biodegradable low irritant resin may be prepared by melt-mixing a monomer of a polymer to a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester which is synthesized by ring-opening polymerization of lactide which is a condensation degree of lactic acid, has a physical property somewhat intermediate between polyamide and polyethylene terephthalate, and mainly comprises a natural vegetable sugar component obtained from potato and corn Although the biodegradability is high, it is generally high in hardness, low in elasticity, and low in durability.

In the biodegradable polymer, the same polymer monomer is melted and mixed. At this time, the biodegradable polymer is partially bonded to the monomer, resulting in partial chain cleavage, resulting in a lower number-average molecular weight as a whole. As the number average molecular weight decreases, it exhibits properties that can be used as a pressure-sensitive adhesive, and the workability is improved.

20 to 30 parts by weight of the lactic acid monomer may be mixed with 100 parts by weight of the polylactic acid. When the monomer is mixed in an amount of less than 20 parts by weight, the number average molecular weight is high and it is hard to use as a pressure sensitive adhesive. If the monomer is used in an amount exceeding 40 parts by weight, migration may occur on the surface.

The blending ratio of the petroleum resin and the biodegradable low irritant resin is preferably 1 to 2: 1 (w / w). When the blending ratio of the petroleum resin is too high, a biodegradable low irritation effect is hardly obtained. If the blend ratio is too high, economical efficiency may be deteriorated and the overall adhesion effect may be lowered.

The content of the tackifier resin is preferably 5 to 40 parts by weight based on the whole composition. If the content is less than 5 parts by weight, the effect of lowering the melt viscosity due to the addition of the tackifier resin is insufficient and the increase of the melt flow index is not so large, so that the workability may not reach a satisfactory level. When the content exceeds 30 parts by weight The rate of increase of the melt flow index due to the excess of the tackifier resin is not large and the economical efficiency is lowered and the content of the thermoplastic polymer is relatively decreased, thereby deteriorating the overall physical properties of the composition.

The rosin serves to improve the overall adhesive strength of the adhesive composition, is harmless to the human body, and acts as a natural preservative. The amount of the rosin is preferably 1 to 5 parts by weight based on the total composition. When the content is less than 1 part by weight, it is difficult to obtain the adhesive strength improving effect. When the content exceeds 5 parts by weight, the adhesive strength during processing increases, and processing into a product becomes difficult.

The plasticizer is used for imparting flexibility and adhesion to a polymer. The plasticizer according to the present invention is not limited to a specific type, and examples thereof include sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol ≪ / RTI >

The content of the plasticizer is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of the addition of the plasticizer is insufficient. If the content exceeds 10 parts by weight, the plasticizers may be excessively used, resulting in poor economical efficiency, and the overall physical properties of the adhesive may be deteriorated.

The filler is used to control the reinforcement and flowability of the composition. The kind of the filler is not particularly limited, and for example, calcium carbonate, clay, bentonite, calcium stearate and the like can be used.

In the meantime, it is preferable to use a mixture of stone powder and pulp powder as a filler in order to reduce odor and bacteria generation while controlling the reinforcement and flowability of the adhesive composition. Due to the compactness of the particles, the stone can realize high strength without using a large amount of additives, and the volume strain due to the surrounding environment is low, so that even when the temperature change is large, the cracking of the adhesive hardly occurs.

The abrasive grains may be in the form of powder of various rocks such as petite, marble, elvan, granite, and jade. Preferably, the abrasive grains having various functions such as antimicrobial activity, antifungal property and ultraviolet ray emission are used.

The pulp powder serves to agglomerate the stones while sucking the liquid components, enhancing the compatibility between the components and enhancing cohesion. At this time, it is preferable that the pulverized powder is mixed at a ratio of about 7: 3 to 8: 2 (w / w).

The content of the filler is preferably 1 to 10 parts by weight relative to the total composition. If the content is less than 1 part by weight, the effect of the addition of the filler is insufficient. If the content is more than 10 parts by weight, the overall physical properties of the adhesive may be deteriorated.

The type of the antioxidant is not limited to a wide range, but includes phenols, aromatic amines, citric acid, ascorbic acid, and the like in order to improve the viscosity and the yellowing phenomenon due to oxidation and decomposition. .

The content of the antioxidant is preferably 0.1 to 1 part by weight based on the whole composition. If the content is less than 0.1 part by weight, the effect of addition of the antioxidant is insufficient. If the content is more than 1 part by weight, the economical efficiency of the adhesive is deteriorated and the overall physical properties may be deteriorated.

On the other hand, the adhesive composition of the present invention is subjected to a pressing operation on the raw fabric, and there is a possibility that the adhesive failure occurs due to the amount of the composition being removed due to the presence of the hole in the fabric.

Thus, the adhesive composition of the present invention may further include nanosilica glass which can improve the adhesive force by uniformly distributing the adhesive composition on the surface of the fabric. In this case, the content of the nanosilica is preferably 0.1 to 5 parts by weight, and the primary particles of the nanosilica is preferably 100 nm or less.

When the content of the nano-silica is less than 0.1 part by weight, the effect of addition of the nano-silica is insignificant. When the content of the nano-silica exceeds 5 parts by weight, not only the adhesive strength is lowered but also blooming occurs on the surface of the adhesive over time.
