Embodiment 1

[0048] Examples 1 to 3 used the resin fiber 12 formed by the electrospinning method of this embodiment as the nonwoven fabric 11 constituting the core material 10 . On the other hand, in Comparative Example 1, conventional glass fibers were used for the core material. In addition, in Comparative Example 2, resin fibers 12 were used in the same manner as in Examples 1 to 3 for the core material. In Example 1 and Comparative Example 2, polystyrene (PS) was used as the raw material of the resin fiber 12 . In addition, Example 2 and Example 3 used polyamide-imide (PAI) as the raw material of the resin fiber 12 .

[0049] [resin fiber]

[0050] The density, that is, the specific gravity, of PS which is the raw material of the resin fiber 12 of Example 1 and Comparative Example 2 is 1.05, which is smaller than 2.5 of the glass fiber of Comparative Example 1. In addition, the specific gravity of PAI which is the raw material of the resin fiber 12 of Example 2 and Example 3 is 1.42...

Abstract

A core material of the vacuum insulation panel of the present embodiment is a core material of a plurality of vacuum insulation panels formed by laminating nonwoven fabrics, wherein the nonwoven fabric is composed of thermosetting resin fibers, and the thermosetting resin fibers are formed of a thermosetting resin.

Description

technical field [0001] The present embodiment relates to a core material of a vacuum insulation panel, a vacuum insulation panel, and a refrigerator. Background technique [0002] Vacuum insulation panels used in various machines and equipment have been required to have high heat insulation and further reduction in thickness and weight. The core material of conventional vacuum insulation panels is mainly formed of glass fibers. However, the glass fiber used as these core materials has a large specificity, and there is a problem that it is difficult to reduce the thickness and weight of the vacuum insulation panel. [0003] prior art literature [0004] Patent Literature [0005] Patent Document 1: Specification of Japanese Patent No. 4713566 Contents of the invention [0006] The problem to be solved by the invention [0007] In order to solve the above-mentioned problems, it has been considered in recent years to form the core material of the vacuum insulation panel ...
