Abstract

Disclosed in the present invention are a polyester elastomer adhesive film and a method of preparing the same. The polyester elastomer adhesive film is prepared by extrusion casting and comprises: a polyester elastomer layer which forms the surface of an adherend, has a specific gravity of 1.25-1.3, and has a melting point of 150-220C; and a polyester hot-melt layer which bonds the polyester elastomer layer to the adherend, has a specific gravity of 1.15-1.25, and has a melting point of 100-150C, wherein the extrusion casting is performed by bringing a raw material layer of the polyester elastomer into contact with a casting roll without bringing a raw material layer of the polyester hot-melt layer into contact with the casting roll. According to the present invention, the polyester elastomer adhesive film is formed as an adhesive film of a double layer structure including the polyester elastomer layer and the polyester hot-melt layer, which imparts elasticity not only to the polyester elastomer layer of surface material, but also to the polyester hot-melt layer of adhesive material. Consequently, the elasticity of the polyester elastomer adhesive film can be enhanced, thus minimizing a decrease in elasticity even for long periods of use when the polyester elastomer adhesive film is applied to adherends such as automobile seats and the like.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing the constitution of a polyester elastomer adhesive film according to an embodiment of the present invention. Fig.
2 is a view showing a method for producing a polyester elastomer adhesive film according to an embodiment of the present invention.

Hereinafter, a polyester elastic film adhesive film and a manufacturing method thereof according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing the construction of a polyester elastomer adhesive film according to an embodiment of the present invention, and FIG. 2 is a view showing a method of producing a polyester elastomer adhesive film according to an embodiment of the present invention.

Referring to FIGS. 1 and 2 together, the polyester elastomer adhesive film 100 according to the present embodiment includes a polyester elastomer layer 110 and a polyester hot melt layer 120.

Reference numeral 150 is a schematic view of an apparatus for producing the polyester elastomer adhesive film (100).

The polyester elastic body layer 110 constitutes the surface of an object to be bonded such as a car seat, has a specific gravity of 1.25 to 1.3, and a melting point of 150 to 220 캜.

The polyester hot melt layer 120 is formed by adhering the polyester elastic body layer 110 to the object to be bonded in a state of being extruded integrally with the polyester elastic body layer 110 and having a specific gravity of 1.15 to 1.25 and a melting point of 100 To 150 < 0 > C.

In this embodiment, the polyester elastomeric adhesive film 100 is produced by extrusion casting, and the raw material layer 121 of the polyester hot-melt layer 120 is made to contact the casting roll 160, which is a cooling roll, The raw material layer 111 of the elastic layer 110 is extruded while contacting the casting roll 160.

The polyester elastomer layer 110 may be formed of polyglycol, alkylene oxides, ethylene glycol, 1,4-butanediol, polytetramethylene glycol , At least one of dimethyl terephthalate, dimethyl isophthalate, terephthalic acid, and isophthalic acid may be included.

The polyester elastomeric adhesive film 100 is obtained by extruding the raw material layer 111 of the polyester elastomer layer 110 and the raw material layer 121 of the polyester hot melt layer 120 from a hopper 155 into a casting roll 160; The raw material layer 111 of the polyester elastomer layer 110 is in contact with the casting roll 160 so that the raw material layer 121 of the polyester hot melt layer 120 is not in contact with the casting roll 160, And the raw material layer 121 of the polyester hot melt layer 120 is extruded while covering the raw material layer 111 of the polyester elastomer layer 110.

The raw material layer 111 of the polyester elastomer layer 110 is formed to have a thickness of about 180 to about 100 nm in order to prevent necking phenomenon that a material extruded in the flow direction of the extruded material is stretched and contracted in the width direction, Extruded at 250 ° C, and the raw material layer 121 of the polyester hot melt layer 120 can be melt-extruded at 130 to 180 ° C.
