Description
本発明は、冷蔵庫扉の周縁部へ取り付けられる取付部と、冷蔵庫本体貯蔵室の開口部周縁に吸着する磁石を収納した磁石保持部と、前記取付部と磁石保持部とを伸縮自在に連結する薄肉の袋状部を有し、発泡性塩化ビニル樹脂組成物の発泡体からなる冷蔵庫扉ガスケットを提供する。
In the present invention, a mounting portion attached to the peripheral edge of the refrigerator door, a magnet holding portion containing a magnet attracted to the peripheral edge of the opening of the refrigerator main body storage chamber, and the mounting portion and the magnet holding portion are stretchably connected. Provided is a refrigerator door gasket having a thin bag-shaped portion and made of a foam of a foamable vinyl chloride resin composition.
ある一形態においては、前記発泡体は１５〜４５％の発泡率を有する。
In one form, the foam has a foaming rate of 15-45%.
本発明の冷蔵庫扉ガスケットは、断熱性に優れ、強度及び耐久性にも優れており、冷蔵庫扉開閉を５万回以上行う耐久性試験の結果、取り付け部、開放力及び保持力に不具合が発生しない。
The refrigerator door gasket of the present invention has excellent heat insulation, strength and durability, and as a result of a durability test in which the refrigerator door is opened and closed 50,000 times or more, problems occur in the mounting portion, opening force and holding force. do not.
発泡率（％）＝（未発泡品比重／発泡品比重−１）×１００％
Foaming ratio (%) = (unpublished foam product density / foamed article gravity -1) × 100%
冷蔵庫の冷蔵室、野菜室及び冷凍室にヒーター装置を設置した。このヒーター装置は、室内の温度を設定した温度に保つように、周囲温度の変動に応じてスイッチのオンオフを行う温度調節機能を備えるものである。その後、冷蔵庫扉を閉めて、冷蔵庫を恒温室に入れた。
Heater devices were installed in the refrigerator compartment, vegetable compartment and freezer compartment. This heater device has a temperature control function that turns the switch on and off according to fluctuations in the ambient temperature so as to keep the indoor temperature at a set temperature. After that, the refrigerator door was closed and the refrigerator was placed in a homeothermic.
