Embodiment 1
[0021] 12 parts of chlorinated polypropylene (50% solids, Eastman, CP343-1) were mixed with 4 parts of chlorinated natural rubber (Bayer, Pergut). 10 parts of xylene was added for dissolution. Then add 4 parts of crosslinking agent (p-benzoquinone dioxime: nano-copper oxide = 1:1, mass ratio), 5 parts of carbon black, 1.5 parts of sulfur, 63.5 parts of mixed xylene, and use a horizontal sand mill for grinding. The fineness is controlled at 5-7μ.
Embodiment 2
[0023] 10 parts of chlorinated polypropylene (50% solids, Eastman, CP343-1) were mixed with 5 parts of chlorinated natural rubber (Bayer, Pergut). 10 parts of xylene was added for dissolution. Then add 4 parts of crosslinking agent (p-benzoquinone dioxime: nano-copper oxide = 1:1, mass ratio), 5 parts of carbon black, 1.5 parts of sulfur, 64.5 parts of mixed xylene, and use a horizontal sand mill for grinding. The fineness is controlled at 5-7μ.
Embodiment 3
[0025] 8 parts of chlorinated polypropylene (50% solids, Eastman, CP343-1) were mixed with 3.5 parts of chlorinated natural rubber (Bayer, Pergut). 10 parts of xylene was added for dissolution. Then add 4 parts of crosslinking agent (p-benzoquinone dioxime: nano-copper oxide = 1:1, mass ratio), 5 parts of carbon black, 1.5 parts of sulfur, 68 parts of mixed xylene, and use a horizontal sand mill for grinding. The fineness is controlled at 5-7μ.
