8. a kind of preparation method of waterproof anti-corrosion glass fabric, which comprises the steps of:
(1) prepared by amide dispersion liquid: being while stirring added to the water the gum arabic powder of formula ratio, by stearic acid, castor oil
It is added after mixing, after mixing, above-mentioned ethylene bis stearamide is added, stirs evenly, obtain amide dispersion liquid；
(2) prepared by maceration extract: in parts by weight by epoxy modified silicone resin, modified polyurethane, sodium bentonite, shock resistance
Modification agent, coupling agent, antioxidant, surfactant, dibutyl phthalate, zinc stearate are uniformly mixed, and are added step (1)
Obtained amide dispersion liquid；
(3) it handles glass fabric: glass fiber plain cloth being put into acid leach slot, 0.3- is added in the acid leach slot
The aqueous hydrochloric acid solution of 0.5mo l/L, aqueous hydrochloric acid solution temperature are 80-90 DEG C, and after impregnating half an hour, glass fiber plain cloth is taken
It is washed till after glass fabric surface is neutrality with clear water out, by glass fiber plain cloth, continuous mode enters baking oven, control
Oven temperature is 200-300 degrees Celsius, keeps the speed operation of 20-30m/mi n, then cooled to room temperature；
(4) it impregnates and dries: processed glass fiber plain cloth in step (3) being impregnated into dipping tank, dipping tank is built-in
The maceration extract for having step (2) to obtain, makes glass fiber plain cloth at the uniform velocity pass through dipping tank, and it is small to be then fed into solidification half in solidifying pool
When, so that glass fibre layer surface is covered with corrosion-resisting resin layer；By ultrasonic 5-8 minutes of completion of cure, it is sent into baking oven drying,
And cooled to room temperature；
(5) wind, pack: glass fiber plain cloth ultrasound 5-8 minutes that processing is completed, winding obtain finished product.
