| titleOfInvention | Thermoplastic semihard polyurethane foam for automobile ceiling and preparation method thereof |
| abstract | The invention discloses thermoplastic semihard polyurethane foam for an automobile ceiling and a preparation method thereof. The foam consists of a material A and a material B, wherein the material A comprises the following raw materials in parts by weight: 100 parts of combined polyether polyol, 5.5-7.0 parts of water, 0.5-1.5 parts of surface active agent, 0.1-0.4 parts of reactive amine catalyst, 0.3-1 part of conventional amine catalyst and 0-5 parts of crosslinking agent; and the material B comprises 150-195 parts by weight of MDI (Diphenyl-methane diisocyanate) system isocyanate. The bottom of the foam generated after components of the material A and the material B are fully mixed and then reacted has the unavailable thickness of smaller than 1.3 percent, the core density of 23-26kg/m<3> and the sound absorption coefficient of 0.5 to 0.7 at the high frequency section of 3,500-6,000Hz. |
