Embodiment Construction
[0028] Below in conjunction with accompanying drawing, the present invention will be further described:
[0029] In this embodiment, the steps of the method for preparing a device for preparing a silicone rubber insulating material that dissipates space charge rapidly are as follows:
[0030] 1. Use a high-precision electronic balance to weigh 100phr (parts per hundreds of rubber) of silicone rubber matrix, 20phr of nano-silicon dioxide (SiO 2 ), 5phr hexamethyldisilazane, 1.3phr polyvinyl silicone oil, 30phr micron silicon carbide (SiC) and 1.0phr bis-pentasulfurizing agent, and place the above-mentioned silicone rubber matrix and filler in a drying oven at 60°C Store in spare.
[0031] 2. Turn on the heating power supply of the roller of the kneader to heat the roller, and keep the temperature of the roller at 40°C. Adjust the roller speed to 30r / min. Adjust the distance between the roller pitch and the baffle, put 100phr of silicone rubber matrix raw rubber into one end ...
