The thermoplastic resin serves as a main component of the composition to control adhesion and cohesion. If the type includes a vinyl group or a hydroxyl group, the type thereof is not particularly limited, and examples thereof include ethylene vinyl acetate copolymer, polyvinylacetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, and 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 based on the total composition. If the content is less than 40 parts by weight, the melt viscosity is high and the melt flow index is low, the workability is very poor, if the content is more than 80 parts by weight it is difficult to exert sufficient adhesive force to be applied directly to the fabric.

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.

The content of the tackifier resin is preferably 5 to 40 parts by weight based on 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.

Antioxidants are intended to improve viscosity change, yellowing, deterioration of adhesion and degradation of durability due to oxidation and decomposition, and the types thereof are not particularly limited, and specifically, phenols, aromatic amines, citric acid, or ascorbic acid may be used. have.

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.
