19 shows a seating portion according to an embodiment of the present invention.

Referring to FIG. 19, the seating portion 700 according to an embodiment of the present invention includes a first sheet layer 710, a waterproof sheet 720, a magnetic joint layer 730, a second sheet layer 740, and silicon It may include a coating layer 750, a buffer portion 760 and the adhesive composition (not shown).

The first sheet layer 710 may be made of an inorganic elastic waterproof material, thereby improving weatherability, corrosion resistance, and durability of the waterproof sheet 720. Here, the inorganic elastic waterproofing material is composed of a special copolymer emulsion and a cement-based special combination aggregate as main components, for example, styrene-butyl acrylic acid copolymer (STYRENE-BUTYL ACRYLATE COPOLYMER) emulsion and cement powder (e.g., port Lant cement, alumina, silica sand, an antifoaming agent, etc.) may be prepared by mixing, or may be prepared by adding water thereto.

The waterproof sheet 720 is disposed on the first sheet layer 710 and may function as a secondary waterproof layer. The waterproof sheet 720 is made of, for example, a metal material such as iron, aluminum, stainless steel, and chromium, and is composed of a thin panel, and can protect the first sheet layer 710 on the lower side and respond to external impact. In particular, the waterproof sheet 720 is composed of a plurality, it can be continuously disposed on the first sheet layer 710. At this time, the magnetic joint layer 730 is disposed on the seam between the waterproof sheets 720, so as to correspond to the stress behavior of the waterproof sheets 720 and maintain airtightness.

The magnetic joint layer 730 may be made of a soft material such as a rubber magnet, and is attached to a seam between the waterproof sheets 720 to seal the seam. Here, the seam between the waterproof sheets 720 is a surface in contact with the continuous waterproof sheets 720, and includes spaces spaced apart within a predetermined distance. For sealing the seam, the magnetic joint layer 730 may be attached to the bottom of the seam and the top of the seam between the waterproof sheets 720, respectively. In addition, since the magnetic joint layer 730 is magnetic, it can be stably attached to the waterproof sheet 720 made of metal.

The second sheet layer 740 may be made of the same inorganic elastic waterproof material as the first sheet layer 710, and in particular, the second sheet layer 740 is made of metal or the like in that water vapor can be discharged to the outside. The waterproof sheet 720 can be prevented from being corroded by moisture inside.

The silicon coating layer 750 is formed on the second sheet layer 740 to protect the second sheet layer 740 from external stimuli. The silicone coating layer 750 provides adhesive force when the transfer portion 600 is in contact with the deck plate 400, including adhesive silicone, so that the deck plate 400 is detached from the transfer portion 600 due to vibration and shock. Can be prevented.

The buffer part 760 is disposed between the plurality of waterproof sheets 720, and may be made of, for example, a soft material such as rubber. By being disposed between the waterproof sheets 720, it is possible to absorb the behavior in the horizontal direction of the waterproof sheets 720, and to maintain the structure of the seating portion 700 more firmly. In particular, even if the soft cushioning portion 760 contracts / expands by the waterproof sheet 720, the airtightness can be continuously maintained by the magnetic joint layer 730 fluidly attached at the upper and lower portions of the cushioning portion 760. .

 An adhesive composition (not shown) may be applied to at least one area of the waterproof sheet 720 to fix and bond the waterproof sheet. The adhesive composition according to an embodiment of the present invention, 40 to 80 parts by weight of a thermoplastic resin, 5 to 40 parts by weight of an adhesive resin, 1 to 5 parts by weight of a resin, 1 to 10 parts by weight of a plasticizer, 1 to 10 parts by weight of a filler, and Contains 0.1 to 1 part by weight of antioxidant. The present invention is a heat-melting adhesive composition, which is generally manufactured in a state of being adhered between a release agent and a silicone band, removes a release agent when applied to a fabric, and performs a pressing operation to perform a role of attaching a silicone band to the fabric. Hereinafter, look at each component in detail.

The thermoplastic resin is a main component of the composition, and functions to control adhesion and cohesion. If it contains a vinyl group or a hydroxyl group, the type is not particularly limited, for example, ethylene vinyl acetate copolymer, polyvinyl acetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, polyurethane It may be composed of any one or more selected from the group consisting of.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight relative to the total composition. If the content is less than 40 parts by weight, the melt viscosity increases and the melt flow index decreases, resulting in very low workability. When the content exceeds 80 parts by weight, it is difficult to exert sufficient adhesion to be applied directly to the fabric.

The tackifying resin is a low molecular weight resin, which improves workability by lowering melt viscosity, improves initial wetness of adhesion and adhesion on the surface of the adhesive material, and enables control of solidification time.

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

The aliphatic hydrocarbon resins include commercial products such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S of Kolon Oil Corporation. In addition, cycloaliphatic hydrocarbon resins include hydrocarbon resins containing dicyclopentadiene (DCPD) as a monomer, and aromatic hydrocarbon resins are commercially available from Kolon Petrochemical's Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000, Hirenol PL-400, etc. In addition, aromatic hydrocarbon resins modified by aromatics include commercially available Koko Emulsion Hikorez T-1080 and Hikorez T-1100. In addition, the hydrogenated hydrocarbon resin may be subdivided into a hydrogenated aliphatic hydrocarbon resin, a hydrogenated aromatic hydrocarbon resin, etc., commercially available from Kolon Oil Corporation Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130, and Sukorez SU-90.

The tackifying resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer, specifically C5 aliphatic resin, C9 aromatic resin, C5 / C9 aliphatic / aromatic copolymer resin, and the like.

In addition, the tackifying resin of the present invention is more preferably characterized in that it is a hydrogenated hydrocarbon resin containing dicyclopentadiene as a monomer, commercially available from Kolon Oil Corporation (Korea) Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, SukorezSU-130, Sukorez SU-90 and others.

Meanwhile, the adhesive composition of the present invention is preferably used by mixing biodegradable hypoallergenic resins together with various petroleum resins described above in order to minimize irritation as it is applied to a portion that directly contacts the skin.

The biodegradable hypoallergenic resin may be prepared by melt mixing a polymer monomer with a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester synthesized by condensation polymerization of lactic acid or ring-opening polymerization of lactide, and has a medium property between polyamide and polyethylene terephthalate, and mainly uses natural vegetable sugar components obtained from potatoes and corn as raw materials. The biodegradability is high, but in general, it has high hardness, low elasticity, and poor durability.

In the biodegradable polymer, the same polymer monomer is melt-mixed. In this case, the biodegradable polymer is partially combined with the monomer, and a chain break is partially generated, thereby reducing the number average molecular weight as a whole. As the number average molecular weight falls, it exhibits physical properties that can be used as an adhesive, and processability increases.

With respect to 100 parts by weight of the polylactic acid, the lactic acid monomer may be mixed with 20 to 30 parts by weight. When the monomer is mixed to less than 20 parts by weight, the number average molecular weight is high and hard to be used as an adhesive, and when the monomer exceeds 40 parts by weight, migration may occur on the surface, which may also be difficult to use as an adhesive.

The mixing ratio of the petroleum resin and the biodegradable hypoallergenic resin is preferably 1 to 2: 1 (w / w), and when the mixing ratio of the petroleum resin is too high, the biodegradable hypoallergenic effect is difficult to produce, and the hypoallergenic resin If the mixing ratio is too high, the economic efficiency is lowered and the overall adhesive effect may be lowered.

In addition, the content of the adhesive resin is preferably 5 to 40 parts by weight compared to the total composition. If the content is less than 5 parts by weight, there is a fear that the effect of lowering the melt viscosity due to the addition of the tackifying resin is insignificant and the increase in the melt flow index is not so great that the workability may not reach a satisfactory level, and the content exceeds 30 parts by weight. When the tackiness resin is exceeded, the increase in the melt flow index is not large, so economic efficiency is lowered and the content of the thermoplastic polymer is reduced, which may decrease the overall physical properties of the composition.

The rosin serves to improve the overall adhesion of the adhesive composition, is harmless to the human body and acts as a natural preservative. The content of the rosin is preferably 1 to 5 parts by weight compared to the total composition. If the content is less than 1 part by weight, it is difficult to obtain an effect of improving the adhesive strength, and if the content exceeds 5 parts by weight, the adhesive force increases during processing, which makes it difficult to process the product.

The plasticizer is used to impart flexibility and adhesion to the polymer, and the type of the plasticizer according to the present invention is not particularly limited, for example, sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol. It may be composed of one or more selected from the group consisting of.

The content of the plasticizer 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 adding the plasticizer is insufficient, and if the content exceeds 10 parts by weight, the economical efficiency may be deteriorated due to the excessive use of the plasticizer, and there is a fear of deteriorating the overall physical properties of the adhesive.

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

On the other hand, in the present invention, it is preferable to use a mixture of stone powder and pulp powder as a filler in order to control the reinforcement and flowability of the adhesive composition while reducing odor and bacteria. Due to the compactness of the particles, high strength can be achieved without using a large amount of additives, and the cracking phenomenon of the adhesive hardly occurs even when the temperature is large due to low volumetric strain according to the surrounding environment.

The stone powder can be used in the form of powders of various rocks such as ocher stone, marble, pulverite, granite, and boulder, and preferably, ocher stone having various functions such as antibacterial, antifungal, and ultraviolet emission is used.

The pulp powder serves to agglomerate the powders while sucking the liquid components, and increases the miscibility between the components and improves the cohesion. At this time, the powder and the pulp powder is preferably 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 adding the filler is insufficient, and if the content exceeds 10 parts by weight, there is a fear that the overall physical properties of the adhesive are lowered.

The antioxidant is for improving the change in viscosity due to oxidation and decomposition, yellowing, deterioration of adhesion and durability, etc., and the type is not greatly limited. Specifically, phenols, aromatic amines, citric acid, or ascorbic acid may be used. You can.

The content of the antioxidant is preferably 0.1 to 1 part by weight relative to the total composition. If the content is less than 0.1 part by weight, the effect of adding an antioxidant is insufficient, and if the content is more than 1 part by weight, not only the economic efficiency of the adhesive is lowered, there is a fear of deteriorating the overall physical properties.

On the other hand, the adhesive composition of the present invention is subjected to a press operation on the fabric, and at this time, there is a possibility that adhesion failure occurs due to the amount of the composition being removed due to the presence of holes in the fabric.

Thus, the adhesive composition of the present invention may further include a nano-silica number that can improve the adhesive force by allowing the adhesive composition to be uniformly distributed on the fabric surface. At this time, the content of the nano-silica is preferably 0.1 to 5 parts by weight, the size of the nano-silica (primary particles) is preferably 100nm or less.

When the content of the nano-silica is less than 0.1 parts by weight, the effect of adding the nano-silica is minimal, and when it exceeds 5 parts by weight, the adhesive strength is not only lowered, but the defect phenomenon that blooming occurs on the surface of the adhesive over time. Can occur. Hereinafter, the configuration of the present invention and its effects will be described in more detail through specific examples and comparative examples.

60 parts by weight of ethylene-vinyl acetate copolymer, 25 parts by weight of Sukorez D-300, 3 parts by weight of rosin, 5 parts by weight of ethylene glycol, 4 parts by weight of ocher stone, 2 parts by weight of pulp powder, and 1 part by weight of ascorbic acid, 170-180 After melt-kneading at ℃ to prepare an adhesive composition and molded into a pellet type.
