| titleOfInvention | High-temperature-resistant wide-temperature-range high-damping polyurethane elastomer material and preparation method thereof |
| abstract | The invention discloses a high-temperature-resistant wide-temperature-range high-damping polyurethane elastomer material and a preparation method thereof. The raw material formula of the material consists of the following components: 12-48 parts of polyurethane prepolymer, 2-8 parts of a small molecular chain extender containing disulfide bonds and 5-25 parts of a dangling chain prepolymer; and (3) carrying out chain extension on the polyurethane prepolymer by using a micromolecule chain extender containing a disulfide bond, and then reacting with the suspension chain prepolymer to obtain the high-temperature-resistant wide-temperature-range high-damping polyurethane elastomer material. The few hanging chain structures can ensure certain mechanical property while improving the damping property of the polyurethane material, and the high temperature resistance of the polysiloxane can improve the maximum long-term service temperature of the polyurethane with the hanging chain; the effective damping temperature range (tan delta is more than or equal to 0.3) of the obtained damping material exceeds 170 ℃, and the damping material can be used for a long time at the temperature of 120 ℃ and has good application effect. |
