Specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1
20 parts of ARZ2000,26.7 parts of HS-4440C and 50 part of HS-4495 are heated 5 hours at 120 DEG C, it is complete to resin
After melting, it is dispersed with stirring uniformly；After being naturally cooling to 55 DEG C, 1 part of DTAP, 0.3 part of 29C90 and 1 part of magnesia is added, stirring is mixed
It closes uniformly to get vinylite.
Embodiment 2
20 parts of HS-4440,28 parts of GRT-3102V and 50 part of GRT-3102VB are heated 4 hours at 135 DEG C, it is complete to resin
After full-fusing, it is dispersed with stirring uniformly；Temperature fall is to after 60 DEG C, being added 1 part of DTBP, 0.3 part of 29C90,0.7 part of magnesia,
It is uniformly mixed to get vinylite.
Embodiment 3
