Manufacturing method of polyurethane foam/clay nano composites for the thermal insulation and the Polyurethane foam/clay nano composites using the same

摘要

Poly is provided a method for producing a polyurethane foam / clay nanocomposite insulator. ; The production method of the present invention the polyurethane foam clay / nanocomposite insulator according to: (a) by reacting the silane-based coupling agent and an organic clay to form a covalent bond between the silane-based coupling agent and an organic clay; (B) forming a covalent bond between the step (a) of the resultant compound with a diisocyanate and then a mixture of di-isocyanates by reacting the compound with the silane coupling agent and, dispersing the clay in the organic diisocyanate compound; And (c) comprises the step of reacting by stirring and then mixing the resultant with a polyol and a chlorine-free blowing agent of step (b), is excellent in heat insulating properties though using a blowing agent that does not affect the ozone layer destruction, such as compressive strength to improve the mechanical properties.
