| titleOfInvention | A kind of hydrophilic isocyanate crosslinking agent and preparation method thereof |
| abstract | The invention discloses a hydrophilic isocyanate crosslinking agent and a preparation method thereof, belonging to the technical field of waterborne crosslinking agents. The preparation method of the hydrophilic isocyanate crosslinking agent of the present invention is as follows: the polyether polysiloxane A containing two hydroxyl groups at the end is mixed with an excess of diisocyanate, and the reaction is complete to obtain an isocyanate-terminated polyisocyanate containing urethane bonds. Ether polysiloxane C; then add a catalyst to the above-mentioned complete reaction system to catalyze the reaction of the remaining diisocyanate and isocyanate-terminated polyether polysiloxane C containing urethane bonds, and finally remove the remaining diisocyanate , to obtain a hydrophilic isocyanate crosslinking agent. The coating obtained by using the hydrophilic isocyanate crosslinking agent obtained by the preparation method as the isocyanate component of the waterborne two-component polyurethane coating has excellent scratch resistance and abrasion resistance. |
