| description | The invention discloses a degradable radiation-curable polyurethane acrylate oligomer and a preparation method thereof. The polyurethane acrylate oligomer is radiation-curable and is degradable above all, thus having excellent environment friendliness and being applicable to the preparation of temporary protective coatings in the field of special protective coatings. The preparation method of the polyurethane acrylate oligomer provided by the invention comprises the following steps: reacting polylactic acid polyol with a diisocyanate compound, and then blocking with hydroxyacrylate to obtain polyurethane acrylate. Thus, the operability of the whole process is high, the raw materials are abundant, the synthesis reaction is simple, and the preparation efficiency is high. |
