| titleOfInvention | Polyurea acrylate oligomer and preparation method and application method thereof |
| abstract | The invention discloses a polyurea acrylate oligomer, which is prepared by reacting an isocyanate-terminated polyurea intermediate product with hindered amine acrylate, and has a specific structure shown as a formula I or a formula II: wherein R is 1 Residual groups after removal of H from the amino group for polyamines, R 2 Residual groups after the polyol has lost H on the hydroxyl group, R 3 Residual groups after two NCO groups have been lost for diisocyanate compounds. The invention also discloses a preparation method and an application method of the polyurea acrylate oligomer, wherein the preparation method comprises the following steps: mixing the polyurea acrylate oligomer with an active diluent and an initiator, and curing and molding under a light source with corresponding wavelength; and (3) placing the cured sample in an environment with the temperature of 80-150 ℃ and treating for 1-48 hours under an anhydrous condition. After the photocuring sample of the polyurea acrylate oligomer is subjected to aftertreatment at 80-150 ℃, the mechanical property of the photocuring sample is improved, and the post-treatment process of the photocuring resin is relatively simple and convenient, so that the polyurea acrylate oligomer has a wide application prospect. |
