The surface heating element 100 for a warm vest according to a preferred embodiment of the present invention is a base sheet 110, two conductors 121, 122 printed on the base sheet 110 and applied with power, The PTC part 130 printed on the base sheet 110 so as to be electrically connected to the conductor 120, covering the conductor 120 and the PTC part 130 and bonded to the base sheet 110. Top sheet 140 is included.

First, the flexible base sheet 110 is cut to be suitable for being applied to a vest and has waterproofness. Preferably, the flexible base sheet 110 has a gas barrier property as well as waterproofness. The flexible base sheet 110 is preferably cut into one back plate and two front plates to be suitable for application to the vest, as shown in FIG. In addition, the flexible base material sheet 110 is not limited as long as it is a sheet material having flexibility, but has a melting point higher than a drying temperature of the conductive paste forming the conductor 120 and the polymer PTC forming the PTC unit 130. It is preferable that it is a raw material.

Thus, when the base sheet 110 is provided, the conductors 121 and (-) poles for connecting the (+) poles of the power supply are formed by using a conductive paste formed by dispersing the conductive particles in the resin solution on one surface thereof. The conductor 120 to be connected may be printed and then dried to obtain the conductor 120. In some cases, the substrate sheet 110 may be formed by first printing the PTC unit 130 and then printing the conductor 120 to be electrically connected to the PTC unit 130. At this time, the printing method is preferably screen printed.

As shown in FIG. 2A, the conductors 121 and 122 may be printed such that the comb teeth are offset from each other while each of them has a comb-like shape, and more preferably, a state of use of the vest. In consideration of the above, the base sheet 110 may be printed in a horizontal direction on a predetermined portion of the upper and lower portions. The conductive particles included in the conductive paste may be any particles having conductive properties, but it is preferable to use silver or carbon black to prevent electromagnetic waves.

Thereafter, the PTC unit 130 is formed by printing with a polymer PTC so as to be electrically connected to the conductors 121 and 122. At this time, since heat is generated only in a space in which the PTC unit 130 is formed, the PTC unit 130 is formed by printing all on the conductors 121 and 122 or under the conductors 121 and 122. In consideration of the manufacturing cost, the PTC unit 130 may be placed on the conductors 121 and 122 or the conductors 121 and 122 as shown in FIG. 2B in consideration of the state of use of the vest. Only part of the bottom may be formed.

In addition, the PTC unit 130 has a temperature control characteristic that maintains a constant temperature when heat is generated while current flows. In order for the PTC unit 130 to exhibit such characteristics more efficiently, the PTC unit 130 It is necessary to have a free space in which) can be properly inflated.

Accordingly, as shown in FIG. 2B, when the PTC part 130 is formed, a plurality of spacing parts 131 on which the PTC is not printed are formed in the PTC part 130. At this time, the gap portion 131 is formed in a rectangular shape in Figure 2b, but irrespective of its shape, the PTC unit 130 may be formed to expand the space, so that it is a dotted line or circular space The space can be chosen according to the needs of the enemy. In addition, the spacer 131 may be formed to be spaced apart in a vertical direction with respect to the printing direction of the conductor 120 in consideration of the electrical connection.

On the other hand, the polymer PTC used to form the PTC unit 130, for example, may use a PTC ink, PTC ink is a polyurethane resin, thermoplastic resins such as ethylene vinyl acetate copolymer and polyethylene resin, carbon black After kneading a predetermined amount with affinity-imparting agents such as a chemical crosslinking agent and a coupling agent and a solvent, the mixture is subjected to heat treatment to obtain a kneaded product, which is then pulverized, and the pulverized product can be diluted with a solvent.

In addition, since the conductive paste and the PTC ink both contain flexible resin binders, the conductor 120 and the PTC unit 130 formed after drying maintain some flexibility.

As such, after the conductor 120 and the PTC unit 130 are formed on one surface of the base sheet 110, the conductor 120 and the PTC unit 130 are covered, and the base sheet 110 is bonded to the base sheet 110.
