常に有効である。The dielectric heating method in the present invention is to heat and bond an adhesive having a high dielectric loss factor under a high-frequency electric field, and the same heating and bonding can be performed by applying a microwave. The high frequency electric field used is in the range of 2 MHz to several hundred MHz. Among them, about 6 to 80 MHz is practical.
When applying this dielectric heating method, it is efficient that only the adhesive is heated best and the other substrates are heated less directly. That is, it is important that the dielectric loss factor of the adhesive is orders of magnitude higher than that of other base materials. The aqueous emulsion adhesive of the present invention satisfies this condition. Even if the adhesive base material has a flexible linear heating wire, the heating wire does not have a break, and if it is a continuous wire, the local heating effect in the high frequency electric field does not occur. In addition, even in the case of an electric wire having a soft polyvinyl chloride jacket having a relatively large dielectric constant (ε = 5 to 10), the dielectric loss factor of the adhesive in the present invention is an order of magnitude higher, and therefore The bonding method is very effective.
