Modified phenolic resin adhesive for nuclear radiation shielding, preparation method and application

The invention relates to the technical field of adhesives, in particular to a modified phenolic resin adhesive for nuclear radiation shielding, which comprises the following components in parts by mass: 50-500 parts of phenolic resin solution, 5-100 parts of nano gadolinium-based metal organic framework material and 1-50 parts of nano filler. Compared with the prior art, the preparation method has the beneficial effects that the porous gadolinium-based metal organic framework material is constructed through coordination self-assembly of gadolinium ions and organic ligands, and then the porous gadolinium-based metal organic framework material is mixed with a phenolic resin solution. The gadolinium-based metal organic framework material is a porous crystalline material formed by self-assembly of inorganic metal ions and organic bridging ligands through coordinate bonds, and has porosity and organic-inorganic hybridization characteristics, so that compared with traditional gadolinium oxide or gadolinium metal pa
