More particularly, the present invention relates to an exothermic mat and a method of manufacturing the exothermic mat, and more particularly, To a surface of the thermoplastic elastomer film, and a bonding layer is provided between the thermoplastic elastomer film and the substrate to bond the substrate to the substrate, thereby improving the adhesive strength and preventing peeling between the laminated bodies.
Description
The present invention relates to an exothermic mat and a method of manufacturing the same. More particularly, the present invention relates to an exothermic mat and a method of manufacturing the exothermic mat, and more particularly, To a surface of the thermoplastic elastomer film, and a bonding layer is provided between the thermoplastic elastomer film and the substrate to bond the substrate to the substrate, thereby improving the adhesive strength and preventing peeling between the laminated bodies.
An area heating element such as a heating mat can be used as various portable heating products such as a household heating mat such as an electric stove, an electric stove, a heating sheet for a car, a heating mat for a baby carriage, and a heating (electric) vest.
The conventional planar heating element may be a nonwoven fabric in which a copper wire (heating wire) is embedded in a nonwoven fabric, and then the nonwoven fabric is laminated with a nonwoven fabric, or a method of laminating a polyethylene terephthalate (PET) Or a linear heating element in which a carbon fiber is embedded in a cable and laminated with a polyethylene film. Since the linear heating element heats the entire area by the local heating, more electric power is consumed than necessary, the heating wire due to overload is broken, and a large amount of electromagnetic waves may be generated, which may adversely affect the human body. On the other hand, the surface heating element has the advantage that the time required to reach the desired temperature is shorter than that of the linear heating element, the power consumption is reduced, and the generation of electromagnetic waves is reduced. In particular, Korean Patent Registration No. 10-1514353 discloses a technique for shielding both an electric field and a magnetic field by adding a structure capable of shielding an electric field and a magnetic field to a substrate on which a heating wire is printed as a conductive ink in an area heating element.
However, due to the nature of the material, such an area heating element may peel off the affinity between the layers, which may lead to overheating and increase the risk of fire due to damage to the heating line during the folding process during use. Therefore, in order to improve the stability of the surface heating element such as the heating mat, it is necessary to develop a technique for preventing the heating wire from being damaged during the folding process and preventing the peeling phenomenon between the stacking body.

Referring to FIG. 8, a method of manufacturing an exothermic mat according to an exemplary embodiment of the present invention includes a first step (S10) of forming at least one heating line on one surface of a substrate, a first step A second step (S20) of laminating adhesive layers, and a third step (S30) of laminating a thermoplastic elastic film having surface irregularities on each of the adhesive layers.

The surface irregularities may be formed by a roll-to-roll process or a roll-to-plate process using a release paper having surface irregularities in a process of manufacturing a thermoplastic elastomer film. Generally, a thermoplastic elastomer film is produced by using a release paper for the purpose of film movement and tension when a thermoplastic elastomer resin in a molten state at a high temperature is extruded and drawn. At this time, a release paper having surface irregularities may be used as the release paper, and a film may be formed by extruding a thermoplastic elastomer resin in a molten state on a surface of the release paper having irregularities on the surface. When the release paper is removed from the formed film in this manner, the surface irregularities in the release paper are transferred to the film to produce a thermoplastic elastomer film having surface irregularities.
The cross-sectional shape of the surface irregularities may be formed in one or more shapes selected from the group consisting of triangular, polygonal, semicircular, convex, and dendritic shapes.
Wherein the surface irregularities have a maximum height of about 3 占 퐉 to about 7 占 퐉 and an arithmetic mean roughness of about 600 nm to about 1100 nm Lt; / RTI >
When the maximum height and the arithmetic average roughness are out of the above ranges, the effect of increasing the surface area is insufficient and the adhesive strength is not sufficiently exhibited. As a result, when the thermoplastic elastomer film Can be peeled off.

Although the description of the power supply unit is omitted, it is the same as the power supply unit described above for the configuration of the heating mat.
According to one embodiment of the present invention, a heating mat that can be applied to an electric cushion, an electric mat, an electric stove, or an electric vest can be manufactured. The heating mat according to the present invention, The substrate can be prevented from being broken due to the elasticity of the thermoplastic elastomer film laminated on both sides of the substrate, damage to the heating wire can be prevented, surface irregularities can be introduced into the thermoplastic elastomer film, It is possible to prevent the occurrence of the peeling phenomenon, and it is expected that the stability is improved and the risk of the peeling is less.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. You will understand. It is therefore to be understood that the embodiments described above are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
