| titleOfInvention | Polyurethane and preparation process thereof |
| abstract | The invention relates to the technical filed of foam production, in particular to polyurethane and a preparation process thereof. In the preparation process, the water of combined polyether reacts with isocyanate to produce carbon dioxide, the carbon dioxide is not an ozone-depleting substance (ODS), and a catalyst promotes the isocyanate and polyether to form a polymer, so that the pore forming performance of the polyurethane is formed, the polyurethane does not produce a bulge phenomenon after being subjected to high temperature, and high temperature resistant performance is formed. The polyurethane has the enough pore-forming performance, the density of the polyurethane can be lower, and accordingly the dimensional stability of the polyurethane is improved. The polyurethane is resistant to high temperature and has good dimensional stability. When the preparation process does not adopt CFCs and HCFCs foaming agents, no ODS or ODP is used for the raw materials and is not used in the production process, an ozone layer in the atmosphere is not damaged, the environment is effectively protected, and the polyurethane meets the limiting value requirements of revised directive 2011/65/EU appendix II of EU RoHS directives 2008/95/E, does not contain cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs) and other harmful substances and is an environmentally-friendly product. |
