Ultraviolet absorbent grafted anti-aging epoxy resin and preparation method thereof

The invention discloses ultraviolet absorbent grafted anti-aging epoxy resin and a preparation method thereof, and belongs to high polymer materials. The ultraviolet absorbent grafted anti-aging epoxyresin structurally comprises an epoxy chain segment, a carbamate chain segment and an ultraviolet absorbent UVp. The high polymer material provided by the invention combines the ultraviolet light absorber, anti-aging carbamate and anti-corrosion epoxy resin and maintains the advantages of the ultraviolet light absorber, the anti-aging carbamate and the anti-corrosion epoxy resin at the same time,and the preparation method of the high polymer material is also provided. The obtained epoxy resin has excellent weather resistance and excellent corrosion protection performance. Meanwhile, the modification method is simple in route; rapid reaction can be achieved at the normal temperature only through addition reaction of hydroxyl and isocyanate, the process is simple and easy to implement, theengineering prospect of th
