| titleOfInvention | The composition of hard polyurethane foam |
| abstract | The present invention is 50 to 70% by weight of polyether polyol prepared by polymerizing 4,4'-diphenylmethane diisocyanate (Polymeric MDI) and (a) sucrose in ethylene oxide and propylene oxide, (b) 10 to 30% by weight of polyether polyol prepared by polymerizing ethylene oxide and propylene oxide on toluene diamine, (c) 20 to 40 polyether polyol prepared by polymerizing ethylene oxide and propylene oxide on glycerine The polyol mixture consisting of the weight percent of the 4,4'- diphenylmethane diisocyanate (Polymeric MDI) is 1.0 to 1.4 molar ratio of the isocyanic acid group (NCO) and the hydroxyl group (OH) of the polyol mixture Cyclopentane flame-retardant rigid polyurethane foam bath, which is used as a foaming agent, and includes cyclopentane free of environmental pollution, and may include a flame retardant, a catalyst, a foam stabilizer, and a deterioration inhibitor. By producing flame-retardant insulators using water as a foaming agent, cyclopentane (environmental pollution) is used as a blowing agent, and has excellent flame-retardant properties by minimizing flammability and explosiveness, which is a disadvantage of cyclopentane, as well as excellent thermal insulation performance and high mechanical strength. By solving the problem of lowering compatibility of pentane and polyol, cyclopentane flame retardant rigid polyurethane foam having physical properties equivalent to or higher than those of conventional rigid polyurethane foam can be easily prepared and used as a coolant. |
