Closed-cell thermosetting plastic foams & methods of producing thereof using acetone and water as blowing agents |
| abstract |
Rigid closed cell polyisocyanate-based insulation foams are created by reacting at least one organic polyisocyanate with compounds having at least two active hydrogen atoms in the presence of acetone used as an expansion, or blowing, agent. Various additives common to rigid closed-cell foam such as cell size controlling silicone surfactants are used to produce a thermal insulating rigid foam. Also, catalysts, flame retardant chemicals, and organic surfactants can be any of the ordinary products normally used by those experienced in the art of foam production. The utilization of acetone and water reduce the amount of hydrocarbon VOCs needed to obtain any given density thus reducing the volatile organic compounds released from the foam insulation. This benefit comes without detriment to the other important qualities needed in such a foam. |
