Embodiment 1
[0027] (1) Raw material pretreatment
[0028] Mix 90 parts of α, ω-terminated hydroxyl polydimethylsiloxane I (kinetic viscosity η = 800000cp), 10 parts of α, ω-terminated hydroxyl polydimethylsiloxane II (dynamic viscosity η = 500000cp), 30 parts Parts of hydrophobic fumed silica R974, 29 parts of activated superfine calcium carbonate, 38 parts of decabromodiphenylethane, and 2 parts of colored carbon black were placed in an oven at 120°C for 8 hours to dry for later use.
[0029] (2) Kneading and mixing of rubber materials
[0030] Put the α, ω-hydroxyl-terminated polydimethylsiloxane I and II pretreated in step (1) into the chamber of the vacuum kneader at one time, adjust the blade speed of the kneader, and heat it to 110°C. After mixing polydimethylsiloxane Ⅰ and Ⅱ evenly, add fumed white carbon black, superfine calcium carbonate, decabromodiphenylethane and colored carbon black powder raw materials in 5 times. The materials in the cavity have been kneaded into a paste....
Embodiment 2
[0034] (1) Raw material pretreatment
[0035] Mix 80 parts of α, ω-terminated hydroxyl polydimethylsiloxane I (kinetic viscosity η = 750000cp), 20 parts of α, ω-terminated hydroxyl polydimethylsiloxane II (dynamic viscosity η = 550000cp), 25 parts Parts of hydrophobic fumed silica R106, 25 parts of superfine silica powder, 32 parts of decabromodiphenylethyl ether, and 1.5 parts of colored carbon black were placed in an oven at 110°C for 6 hours and dried for later use.
[0036] (2) Kneading and mixing of rubber materials
[0037] Put the α, ω-hydroxyl-terminated polydimethylsiloxane I and II pretreated in step (1) into the chamber of the vacuum kneader at one time, adjust the blade speed of the kneader, and heat it to 105°C. After mixing polydimethylsiloxane Ⅰ and Ⅱ evenly, add fumed white carbon black, ultrafine silicon micropowder, decabromodiphenylethyl ether and colored carbon black powder in 4 times. The materials inside have been kneaded into a paste. After the powder...
Embodiment 3
[0041] (1) Raw material pretreatment
[0042] 100 parts of α, ω-terminated hydroxyl polydimethylsiloxane (kinetic viscosity η = 900000cp), 26 parts of hydrophobic fumed silica TS-720, 32 parts of activated nano-calcium carbonate, 24 parts of decabromodiphenylethylene Alkanes, 8 parts of antimony trioxide, and 1.2 parts of colored carbon black were placed in an oven at 125°C and dried for 10 hours, and set aside.
[0043] (2) Kneading and mixing of rubber materials
[0044] Put all the α, ω-terminated hydroxyl polydimethylsiloxane pretreated in step (1) into the material chamber of the vacuum kneader, adjust the speed of the blade of the kneader, and wait until the temperature is raised to 100°C, the gas phase silica , Nano-calcium carbonate, decabromodiphenylethane, antimony trioxide and colored carbon black powder raw materials are added in 5 times, and it should be ensured that the materials in the material cavity have been kneaded into a paste before each powder is added. ...
