Abstract

A vacuum insulated panel according to an embodiment of the present invention is provided with: a core material comprising resin fibers; and a monomer-adsorbing material that is added to the core material and that adsorbs monomers derived from the resin fibers.

First claim

1 . A vacuum insulation panel comprising:
a core material composed of resin fibers; and a low-molecule adsorbent, added to the core material, for adsorbing low molecules derived from the resin fibers.

2 . The vacuum insulation panel according to claim 1 , further comprising a moisture adsorbent, added to the core material, for adsorbing moisture,
wherein an addition amount of the low-molecule adsorbent is larger than an addition amount of the moisture adsorbent.

3 . The vacuum insulation panel according to claim 1 ,
wherein an adsorption system of the low-molecule adsorbent and an adsorption system of the moisture adsorbent are different from each other.

4 . The vacuum insulation panel according to claim 1 ,
wherein the core material has a groove section, and in a predetermined region including the groove section, a small-addition-amount region in which an addition amount of the low-molecule adsorbent is smaller than in other region is provided.

5 . The vacuum insulation panel according to claim 4 ,
wherein a large-addition-amount region in which an addition amount of the low-molecule adsorbent is larger than that in the small-addition-amount region is provided.

6 . The vacuum insulation panel according to claim 4 ,
wherein the core material has a flat plate shape, the groove section is provided in one surface of the core material, and the large-addition-amount region is provided in the same surface as that the groove section is provided in.

7 . A core material included in the vacuum insulation panel according to claim 1 .

8 . A refrigerator comprising the vacuum insulation panel according to claim 1 .

9 . The vacuum insulation panel according to claim 2 ,
wherein an adsorption system of the low-molecule adsorbent and an adsorption system of the moisture adsorbent are different from each other.

10 . The vacuum insulation panel according to claim 2 ,
wherein the core material has a groove section, and in a predetermined region including the groove section, a small-addition-amount region in which an addition amount of the low-molecule adsorbent is smaller than in other region is provided.

11 . The vacuum insulation panel according to claim 3 ,
wherein the core material has a groove section, and in a predetermined region including the groove section, a small-addition-amount region in which an addition amount of the low-molecule adsorbent is smaller than in other region is provided.

12 . The vacuum insulation panel according to claim 5 ,
wherein the core material has a flat plate shape, the groove section is provided in one surface of the core material, and the large-addition-amount region is provided in the same surface as that the groove section is provided in.

13 . A core material included in the vacuum insulation panel according to claim 2 .

14 . A core material included in the vacuum insulation panel according to claim 3 .

15 . A core material included in the vacuum insulation panel according to claim 4 .

16 . A core material included in the vacuum insulation panel according to claim 5 .

17 . A refrigerator comprising the vacuum insulation panel according to claim 2 .

18 . A refrigerator comprising the vacuum insulation panel according to claim 3 .

19 . A refrigerator comprising the vacuum insulation panel according to claim 4 .

20 . A refrigerator comprising the vacuum insulation panel according to claim 5 .
