Abstract
Disclosed are a polyol composition using carbon dioxide, a method for preparing a polyurethane foam using the polyol composition, and a polyurethane foam prepared using the method. A method for preparing a polyurethane foam includes reacting isocyanate with a polyol composition containing a polyol compound having a synthetic polyol containing carbon dioxide, a chain extender, and a foaming agent.
Claims15
A polyol composition comprising:
- a polyol compound;
- a chain extender;
- and
- a foaming agent,
- wherein the polyol compound comprises a base polyol and a synthetic polyol, and
- the synthetic polyol comprises carbon dioxide (CO2).
3 more elements
A method for preparing a polyurethane foam, the method comprising:
- mixing, in a primary reaction, a polyol composition with a first isocyanate, followed by foaming, to provide a primary reaction mixture;
- and
- mixing, in a secondary reaction, the primary reaction mixture with a second isocyanate to provide a secondary reaction mixture,
- wherein the polyol composition comprises:
- a polyol compound having a base polyol and a synthetic polyol containing carbon dioxide (CO2), a chain extender, and a foaming agent.
2 more elements
A polyurethane foam comprising:
- a polyol composition having a polyol compound comprising a base polyol and a synthetic polyol containing carbon dioxide (CO2), a chain extender;
- and a foaming agent;
- a first isocyanate;
- and
- a second isocyanate,
- wherein the polyol composition has been mixed with the first isocyanate, followed by a foaming, to provide a primary reaction mixture, and
- wherein the primary reaction mixture has been mixed with the second isocyanate to provide the polyurethane foam.
