Embodiment Construction
[0012] A polyester fiberglass material with withstand voltage is made of the following raw materials in parts by weight: unsaturated polyester 112, nylon 614, glass fiber 24, carbon nanotube 1.5, shell powder 12, silica airgel 2.4, Sodium dodecylbenzenesulfonate 1.3, oxidized polyethylene wax 6, molybdenum oxide 2, white oil 3, silane coupling agent KH53010, aluminum borate whisker 1, methyl ethyl ketone peroxide 2.9, 1% ethanol aqueous solution in proper amount.
[0013] The manufacture method of the polyester fiberglass material of described a kind of withstand voltage strength, comprises the following steps:
[0014] (1) Put the glass fiber in the ultra-low temperature treatment equipment at minus 100°C to minus 200°C for ultra-low temperature treatment for 10-15 hours, take it out and naturally return to temperature, put it in a muffle furnace at a temperature of 530-590°C, heat treatment for 1-2 Hours, natural warming made pretreated glass fiber;
[0015] (2) Stir and mi...
