The tackifier resin is a low molecular weight resin, lowers the melt viscosity to improve workability, improves the initial wettability of adhesion and adhesion of the adhesive on the surface of the adherend, and enables control of the solidification time.

The tackifying resin is not particularly limited in kind, but is preferably a petroleum resin. More specifically, the tackifier resin may be composed of one or more selected from the group consisting of aliphatic hydrocarbon resins, alicyclic hydrocarbon resins, aromatic hydrocarbon resins, aromatic hydrocarbon-modified aliphatic hydrocarbon resins, and hydrogenated hydrocarbon resins.

The aliphatic hydrocarbon resins are commercial products such as Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S, and the like. In addition, alicyclic hydrocarbon resins include hydrocarbon resins containing dicyclopentadiene (DCPD) as monomers, and aromatic hydrocarbon resins are commercially available from Kolon Oil Co., Ltd. of 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. In addition, aromatic hydrocarbon-modified aliphatic hydrocarbon resins include Hikorez T-1080, Hikorez T-1100, etc. of Kolon Oils. Hydrogenated hydrocarbon resins can also be subdivided into hydrogenated aliphatic hydrocarbon resins, hydrogenated aromatic hydrocarbon resins, and the like, and commercially available from Kolon Oil Co., Ltd. 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, and specifically, a C5 aliphatic resin, a C9 aromatic resin, a C5 / C9 aliphatic / aromatic copolymer resin, or the like may be used.

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

On the other hand, the adhesive composition of the present invention, in order to minimize the damage of the table 10 as applied to the portion directly contacting the table 10, it is preferable to use a mixture of biodegradable hypoallergenic resins in the various petroleum resins described above Do.

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

The polylactic acid is a polyester synthesized by polycondensation of lactate or ring-opening polymerization of lactide, and has a medium physical property between polyamide and polyethylene terephthalate, and is mainly made of natural vegetable sugar components obtained from potatoes and corn. Biodegradability is high, but generally has high hardness, low elasticity, and poor durability.

The biodegradable polymer is melt-mixed with the same polymer monomer, wherein the biodegradable polymer is partially bonded with the monomer to cause chain breakage, thereby lowering the overall number average molecular weight. As the number average molecular weight falls, the physical properties that can be used as an adhesive are exhibited, and the workability is increased.

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

It is preferable that the mixing ratio of the petroleum resin and the biodegradable hypoallergenic resin is 1 to 2: 1 (w / w). When the mixing ratio of the petroleum resin is too high, the biodegradable hypoallergenic effect is less likely to occur. If the mixing ratio is too high, economic efficiency may be lowered and the overall adhesive effect may be lowered.

In addition, the content of the tackifying resin is preferably 5 to 40 parts by weight relative to the total composition. If the content is less than 5 parts by weight, the effect of lowering the melt viscosity due to the addition of the tackifying resin is insufficient, and there is a fear that the increase in the melt flow index is not so large that the workability may not be satisfactorily reached, and the content is more than 30 parts by weight. If the melt flow index increase rate due to the excess of the tackifier resin is not large, the economical efficiency is lowered and the content of the thermoplastic polymer is relatively reduced, thereby reducing the overall physical properties of the composition.

The rosin acts to improve the overall adhesion of the adhesive composition and 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 based on 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, there is a problem in that the adhesion is increased during processing, making it difficult to process the product.

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

The amount 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 insignificant. If the content is more than 10 parts by weight, the economical efficiency may be reduced by excessive use of the plasticizer, and there is a concern that the overall physical properties of the adhesive may be lowered.

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

On the other hand, the adhesive composition of the present invention is formed on the inner surface of the guide frame 20 to be in direct contact with the table 10, odor and bacteria are likely to occur in the application environment. Therefore, in order to reduce the odor and bacteria generation while controlling the reinforcement and flow of the adhesive composition, it is preferable to use a mixture of stone powder and pulp powder as a filler. Stone powder can achieve high strength without using additives due to the compactness of the particles, and the cracking of the adhesive hardly occurs even when the temperature change is large due to low volumetric strain according to the surrounding environment.

The stone powder may be used in the form of powder of various rocks such as loess, marble, elvan, granite, gemstone, and is characterized in that the loess having various functions such as antibacterial, antifungal, and ultraviolet radiation is used.

The pulp powder serves to agglomerate the stone powders while sucking the liquid components, to improve the miscibility and improve the cohesion between the components. At this time, the stone powder and the pulp powder is preferably mixed in a ratio of about 7: 3 to 8: 2 (w / w).

The content of the filler 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 adding the filler is insignificant, and if the content is more than 10 parts by weight, there is a concern that the overall physical properties of the adhesive may be lowered.

The antioxidant is intended to improve the change in viscosity, yellowing, deterioration of adhesion and degradation of durability due to oxidation and decomposition, and the type thereof is not particularly limited and specifically, phenols, aromatic amines, citric acid, or ascorbic acid may be used. Can be.

The content of the antioxidant is preferably 0.1 to 1 parts by weight relative to the total composition. If the content is less than 0.1 part by weight, the effect of the addition of the antioxidant is insignificant, and if the content exceeds 1 part by weight, not only the economical efficiency of the adhesive is lowered but also the overall physical properties may be lowered.

On the other hand, the adhesive composition of the present invention may further include a nano silica that can improve the adhesion by allowing the adhesive composition to be uniformly distributed on the landing gear 120 surface. At this time, the content of the nano silica is preferably 0.1 to 5 parts by weight, and the size of the nano silica (primary particles) is preferably 100 nm or less.

If the content of the nano-silica is less than 0.1 parts by weight, the effect of the addition of nano-silica is insignificant, and if the content exceeds 5 parts by weight, not only the adhesive force is lowered but also a bad phenomenon that blooming (blooming) occurs on the surface of the adhesive over time May occur.

Experimental Example

(1) Mesh adhesive strength

In order to evaluate the mesh adhesive strength of the hot melt adhesive, the adhesive pellets quantitated between two pieces of overcoat fabrics were melt-coated at 170 ° C., and then pressed at 60 kgf / cm 2 for 30 seconds at 130 ° C. Adhesive strength (kgf / cm 2) was measured.

 (2) Melt Flow Index

The heating cylinder of the melt flow rate meter was filled with a pellet type adhesive and melted at 160 ° C. for about 5 minutes. The weight (g) of the adhesive passed through the cylinder for 10 minutes was measured by putting a weight of 3 kg.
