Choose 60% epoxy resin, 10% C20,30% silicon-dioxide, 5% acetone, 2% silane coupling agent, 1% polyamide resin, 1% thanomin.
At first silica filler is processed: silane coupling agent and acetone mixed diluting, and add silicon-dioxide fully to stir, then temperature is risen to 100-120 ℃, then use ultrasonic wave high speed dispersion 20min, dry stand-by.
Then process epoxy resin: by epoxy resin, C20, polyamide resin and thanomin mix and blend.
The silicon-dioxide that finally will process with the ultrasonic wave filling method mixes with the epoxy resin of processing, and high speed dispersion 2h, obtain the high heat conductive insulating tackiness agent.
The present invention has disclosed a kind of High Performance Insulation tackiness agent, by improved silica filling epoxy resin matrix, be the epoxy resin modified adhesive, by improved silica filling epoxy resin matrix, there is high heat conduction, high-mechanical property, can be applicable in the heavy-duty motor electrical equipment.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes content of the present invention to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
