| titleOfInvention | Low odor and low VOC polyurethane sheet and preparation method and application thereof |
| abstract | The invention relates to a low-odor and low-VOC polyurethane sheet, a preparation method and application thereof, and mainly solves the problem that the low-odor polyurethane sheet in the prior art needs to be prepared using a chlorofluoroalkane foaming agent, which is not environmentally friendly and has high VOC content. The problem is that the present invention adopts a low-odor and low-VOC polyurethane sheet, which is composed of component I and component II, and the weight ratio of component I to component II is 100:85-200; The number of parts includes: polyether polyol I: 62-85 parts, polyether polyol II: 5-15 parts, polyether polyol III: 1-10 parts, foam stabilizer: 0.3-2.5 parts, catalyst: 0.2 ～1.3 parts, water: 4～10 parts; Component II includes 85～200 parts by weight of modified isocyanate, and the technical scheme of the preparation method solves the above problems well, and can be used for the industrial application of automobile ceiling middle. |
