[0035]Example 1
[0036]Prepare UV photocuring polyfunctional epoxy active diluent:
[0037]S1, under a nitrogen gas conditions, 1 mol of tetramethyltrinylcyclic tetra siloxane, 100 ml of n-hexane, 200 μgspeier catalyst were mixed and uniformly added to the reactor, add 4 mol of tetramethylene silicon oxygen at 60 ° C. After the dropwise addition, the reaction was stirred at 60 ° C for 5 h;
[0038]S2, under a nitrogen gas conditions, 4 mol allyl glycidyl ether was added dropwise to the reaction system obtained by step S1. After the dropwise addition, the reaction was stirred at 60 ° C for 5 h, then at 100 ° C, -0.1MPa decompression Distillation 1 h, it is obtained.
[0039]The prepared UV photocurable polyfunctional epoxy active diluent structure is as follows:
