MANUFACTURING METHOD OF A REFRIGERATOR DOOR WITH HIGH QUALITY INSULATION AND RECOVERY PERFORMANCE

摘要

The present invention is related with a refrigerator door the inner and exterior faces of which are coated with plastic material and which does not contain polyurethane in its insulation system. In the refrigerator door according to the present invention that provides the insertion of a combined structure, prepared in advance in a mould assembly consisting of two materials, namely a vacuum insulation liner (4) and an expanded polystyrene (5), into the insulation gap between the plastic liners (2, 3) forming the inner and exterior surfaces; as the vacuum insulation liner has better insulating properties compared to polyurethane, it has been possible to reduce the insulation thickness and thus to enlarge the inner volume of the refrigerator. Due to the fact that no polyurethane has been used in the insulation system and since the selected materials can easily be disassembled, an insulation system which can be completely recycled after completing its service life, is obtained.
