| titleOfInvention | Thermal reversible crosslinking modified elastomer material and preparation method thereof |
| abstract | The invention provides a thermal reversible crosslinking modified elastomer material and a preparation method thereof, wherein the preparation method comprises the following steps: firstly, grafting carboxyl onto a molecular chain of an elastomer with double bonds through sulfydryl-alkene click reaction, and then carrying out esterification reaction on the modified elastomer after carboxyl grafting and a polyepoxy compound to obtain the thermally reversible crosslinking modified elastomer material. The prepared thermal reversible crosslinking modified elastomer material has better mechanical property and solvent resistance under the condition of room temperature, has long service life, and can be remolded and molded under the heating condition, thereby realizing the recycling of the elastomer material. In addition, the invention can regulate and control the elongation at break and the breaking strength of the prepared thermal reversible crosslinking modified elastomer material by regulating the ratio of the mole number of epoxy groups in the polyepoxy compound to the mole number of carboxyl groups in the modified elastomer after carboxyl grafting. |
