Embodiment 1
[0033] The preparation process of the cross-arm of electric tracking corrosion-resistant and highly hydrophobic type power transmission composite material provided in this embodiment, the reinforcement material of the cross-arm mandrel of the electric tracking-resistant composite material adopts 12K high-strength E glass fiber, and the resin adopts high-strength epoxy resin. The ratio of agent and release agent is 1:1.3:0.05.
[0034] First, add the weighed resin raw materials into the mixing tank one by one, stir at a high speed for 60 minutes at a vacuum of 50 Pa, take it out after stirring evenly, and put it into the glue tank. The glass fiber passes through the glue tank at a speed of 60mm / min to obtain a prepreg. The prepreg is converged into the molding mold through the tetrafluoroethylene guide plate. The temperature of the pultrusion molding mold is 200°C, and the high temperature curing temperature is 190°C.

Embodiment 2
[0039] This example provides a preparation process for a cross-arm of electric tracking corrosion-resistant and highly hydrophobic composite material for electricity transmission. The cross-arm mandrel of the electric tracking-resistant composite material is reinforced with 24K high-strength E glass fiber, and the resin is high-strength epoxy resin. , Curing agent, release agent ratio is 1:1.6:0.05.
[0040] First, add the weighed resin raw materials into the mixing tank in turn, stir at a medium speed for 30 minutes at a vacuum of 50 Pa, and then stir for 30 minutes at a high speed. After stirring evenly, take it out and add it to the glue tank. The glue tank is preheated. The temperature is 70 ℃, and the glass fiber after 500 ℃ high temperature treatment passes through the glue tank at a speed of 30mm / min to obtain prepreg. The prepreg is converged into the forming mold through the tetrafluoroethylene guide plate. The heat treatment temperature is 150°C.
