1. a kind of silicon rubber system solidification compound contains organopolysiloxane (A), organic hydrogeneous poly- silicon oxygen containing vinylAlkane (B) and silicon dioxide granule (C),Wherein, the organopolysiloxane (A) containing vinyl is the straight-chain organopolysiloxane (A1) containing vinyl,The straight-chain organopolysiloxane (A1) containing vinyl is the straight-chain organopolysiloxane by the 1st containing vinyl(A1-1) and straight-chain organopolysiloxane (A1-1) of the contents of ethylene than the 1st containing vinyl it is high the 2nd containing the straight of vinylChain organopolysiloxane (A1-2) is composed, and the 1st straight-chain organopolysiloxane (A1-1) containing vinyl contains with the 2ndThe mixing ratio of the straight-chain organopolysiloxane (A1-2) of vinyl is with weight ratio meter for (A1-1):

  • (A1-2)=1;

    0.05~1;

    0.6It is described organic hydrogeneous poly- relative to 1 mole of vinyl in the straight-chain organopolysiloxane (A1) containing vinylThe hydride base unit weight of siloxanes (B) reaches 0.5~5 mole of amount,The content of the organohydrogenpolysiloxane (B) is relative to 100 parts by weight of organopolysiloxane (A) containing vinylFor 0.1~15 parts by weight,The organohydrogenpolysiloxane (B) is straight-chain organohydrogenpolysiloxane (B1) and the organic hydrogeneous poly- silicon oxygen of branchedThe combination of alkane (B2), the mixing ratio of straight-chain organohydrogenpolysiloxane (B1) and branched organohydrogenpolysiloxane (B2)With weight ratio meter for (B1);

    (B2)=1;

    0.1~1;

    1,The content of the silicon dioxide granule (C) be 26.0 weight % or more and 32.0 weight % hereinafter,It can get and show that JIS K6253 (2006) A type duroscope shows that hardness is 40.0 or more object after hardeningThe silicon rubber of property.
