In this work

the silicone rubbers of the containing additives were vulcanized by

60

Co gamma ray radiation. Novel high strength silicone rubbers were prepared under varying vulcanization conditions. The tensile strength and the tearing strength of the silicone rubbers were 11.40 Mpa and 42.03 kN/m

respectively.

The effect of the radiation condition on the gel fraction

crosslinking regulation

and the network molecular weight were studied. The ratio of the probability of chain scission to the probability of crosslinking (p

0

/q

0

)

the initial gel dose (D

g

)

and crosslinking G value were 0.22

0.8 kGy

and 9.1

respectively.

For extensive application

study of high strength silicone rubber has great significance.
