2) original slurry material is obtained into mass concentration 2~5%, 40~60 ° of SR of beating degree, weight in wet base 2 by beater or fiberizer
The slurry A of~16g；
3) slurry A is carried out compound through double cylinders, it is compound after by squeezing, sprayed after squeezing by spray pattern in page surface
Coating fluid, coating fluid a concentration of 1~3% are applied, coating solution amount is 0.1~1.0g/m2, coating fluid is polycarboxylic acids and PVA, is gathered
The mass ratio of carboxylic acid and PVA are 1:1~1：4；
4) it and then drying, press polish, batches and obtains electrolytic capacitor paper after cutting.
Preferably, the jute pulp include sisal hemp pulp, manila pulp, jute slurry, Chinese jute pulp, flax pulp, wild goose latex,
One or more of pineapple leaves slurry and wingceltis latex.
Preferably, the mass concentration 2~4% of the jute pulp, beating degree 40~50 ° of SR, 8~12g of weight in wet base.
