1. the preparation technology of a silicon glue lens substrate, it is characterised in that with cyclosiloxane, ring hydrogen siloxaneAnd raw material based on linear silicones;

  • Wherein, the preparation technology of described base material comprises the following steps;

    A () adds among strong acid extremely described cyclosiloxane, described ring hydrogen siloxane and described linear silicones,Carry out ring-opening polymerization and form it into the polysiloxane mixture of the tool si-h bond represented with formula (I), wherein, instituteThe si-h bond quantity stating formula (I) is n;

    B () adds hydrophilic compounds in the polysiloxane mixture of the most described tool si-h bond represented with formula (I),And carry out silicon hydrogenation with platiniferous catalyst (Pt/C) so that it is gathering of the tool hydrophilic side-chains that formation represents with formula (II)Mixture of siloxanes;

    Wherein, described hydrophilic compounds is (n+A) with the mole number ratio of formula (I);

    1, and A value is between 5-100Constant, described formula (I) and formula (II) are the most as follows;
