Embodiment 1
[0035] Embodiment 1 A kind of preparation of glue (do not contain additive)
[0036] The present embodiment provides a kind of preparation of glue, comprising:
[0037](1) At room temperature, add 3 mol of hexamethylenetetramine and 3 mol of urea into deionized water and mix evenly to prepare a 1 L mixed solution to form the first mixed solution;
[0038] (2) Dissolve U3O8 in concentrated nitric acid at room temperature and add deionized water to prepare a 2.8M uranyl nitrate solution with a pH value of 1.8-2.2;
[0039] Take 5ml of the uranyl nitrate solution, add 1ml of complexing agent acetylacetone dropwise into the solution and mix evenly to form the second mixed solution;
[0040] (3) Take the first mixed solution and the second mixed solution and mix them uniformly at a volume ratio of 1:1 to form a third mixed solution to obtain the glue.
[0041] In the obtained glue solution: 1.4 mol / L of metal ion, 1.5 mol / L of hexamethylenetetramine, 1.5 mol / L of urea, and 0.8 mo...
