Problems solved by technology

However, when the paraffin wax undergoes a phase transition by heating, it becomes liquid, and there is a danger of igniting and catching fire
In order to use paraffin as a thermal storage material, it is necessary to store it in an airtight container such as a bag to prevent the paraffin from leaking from the thermal storage material, and it is limited by the application field

Embodiment 1～ Embodiment 5

[0203] Each component was heat-mixed at 50 degreeC by the compounding ratio shown in Table 1, and the curable composition was obtained. Next, under the condition of 50° C., the curable composition was applied onto the PET film using a bar coater so that the thickness of the cured heat storage layer became 200 μm. The photocuring treatment of the heat storage layer was performed by irradiating ultraviolet rays (wavelength: 365 nm, intensity: 200 mW) toward the heat storage layer in an inert gas oven (temperature: 70° C.) replaced with nitrogen. The amount of ultraviolet radiation is set to 3000mJ / cm 2 .

Abstract

The invention discloses a method for producing a heat storage sheet according to the first aspect of the present disclosure, and the method includes a step for forming a heat storage layer that includes a heat storage component that exhibits a heat storage property by phase transition and a photocuring agent on the surface of a base film and a step for curing the heat storage layer by applying active energy rays to the heat storage layer in a state in which the temperature of the heat storage layer is higher than the phase transition temperature of the heat storage component. The method for producing a heat storage sheet according to the second aspect of the present disclosure includes a step for forming a heat storage layer including a heat storage component that exhibits a heat storage property by phase transition and a thermosetting agent on the surface of a base film and a step for curing the heat storage layer by heating the heat storage layer to a temperature 20 DEG C or more higher than the phase transition temperature of the heat storage component.

Description

technical field [0001] The present disclosure relates to a method of manufacturing a thermal storage sheet. Background technique [0002] The heat storage material is a material that can extract stored energy as heat as needed. Heat storage materials can be used in air-conditioning equipment, floor heating equipment, refrigerators, electronic parts such as integrated circuit (IC) chips, interior and exterior materials of automobiles, automobile parts such as carbon tanks, and thermal insulation containers. [0003] In terms of the amount of heat, latent heat storage using phase transition of a substance is widely used. Water-ice is widely known as a latent heat storage material. Water-ice is a substance with a large amount of heat, but the phase transition temperature is limited to 0°C under atmospheric pressure, so the range of applications is also limited. As a latent heat storage material having a phase transition temperature higher than 0° C. and 100° C. or lower, par...
