(6) get the addition reaction inhibitor;
Then form respectively in proportion A component sizing material and B component sizing material.
9. the described encapsulation solar battery sheet of the arbitrary claim of claim 1 to 8 is with the using method of two component liquid silica gels, it is characterized in that, A component sizing material and the B component sizing material ratio in 1: 1 is fully mixed, under vacuum condition, the bubble in the sizing material is removed fully, then toasted 10 minutes under 100 ℃ of conditions of high temperature with sun power backboard, solar battery sheet, photovoltaic glass, can obtain silicone resin type elastomerics.
