Abstract
The present invention is the production method of the semiconducting paper of the shielding material of a kind of conductance between conductor and semiconductor, meaning.This method is that carbon black is added paper pulp, and add reinforcing materials such as fibrous type polyvinyl alcohol, cationic starch, weak cation polyacrylamide, the semiconducting paper of being produced and semiconductor crepe paper percentage elongation is big, closed performance good, folding, resistance stabilization, be evenly distributed.Production technology is simple, only needs to use the two cylinder paper machines of common twin-tub.
Description
The present invention relates to electrical material, the production method of the semiconducting paper of particularly a kind of conductance between conductor and semiconductor.
The surface type semi-conducting material that the shielding material that existing electric equipment uses has metal forming, semi-conducting rubber band and dip coating to produce.These materials all in various degree exist the coating inhomogeneous, coating easily comes off, shortcomings such as resistance characteristic instability.
Semiconducting paper is a kind of novel electrical material, and its conductance though be called semiconductor, is different from the semi-conducting material of unilateal conduction between conductor and semiconductor.This semiconducting paper is the dedicated paper of extra-high-tension cable and other high-voltage electrical equipment shielding usefulness, can have the function of shielding static, balanced electric field at transformer industry, instrument transformer industry, line cable industry alternative metals paper tinsel, semi-conducting rubber band and surface type semi-conducting material.
The purpose of this invention is to provide a kind of method of producing semiconducting paper with existing paper making equipment.
The production method of semiconducting paper of the present invention is:
The raw material weight ratio:
Sulfate true qualities wood pulp 100
Carbon black 9-14
Fibrous type polyvinyl alcohol 2-7
Alcohol water blend (concentration 5%) 25-40
Cationic starch 2-4
Weak cation polyacrylamide 0.1-0.5
Technology:
-permeate carbon black with alcohol water blend
-the wood pulp beater of packing into is discongested, add roll setting making beating behind the carbon black
-to pull an oar to beating change 35 degree adding fibrous type polyvinyl alcohol, temperature control is lower than 60 ℃
-pull an oar to beating degree 45 degree adding cationic starches
-copy paper, add the weak cation polyacrylamide simultaneously
The semiconducting paper of producing with the present invention has that closed performance is good, body light, folding, resistance stabilization, advantage such as be evenly distributed.Its production technology is simple, the two cylinder paper machines of the common twin-tub of use can be produced.
In order to produce the bigger semiconductor crepe paper of percentage elongation, half-dried wrinkling when copying paper, can on a cylinder of the two cylinder paper machines of twin-tub, creping doctor be installed, the two cylinder oven dry.
Embodiment one, is that 5% alcohol water blend permeates 90 kilograms of carbon blacks with 250 kilograms of concentration earlier.1000 kilograms of sulfate true qualities wood pulps beater of packing into is discongested, discongest the back and in time add carbon black with the alcohol infiltration.About 2 hours of the light beating that falls then makes the carbon black firm attachment on fiber.When the slurry beating degree reaches 35 when spending, add 20 kilograms of fibrous type polyvinyl alcohol to strengthen the intensity of paper, the control temperature is no more than 60 ℃ during making beating, and is dissolved to prevent vinal.Beat when slurry beating degree to 45 is spent, adds 20 kilograms of cationic starches, with the yield of staying of the tensile strength of enhancing paper and carbon black.Copy paper with the two cylinder paper machines of twin-tub then.When copying paper, add 1 kilogram of weak cation type polyacrylamide at web-roll core case position, make the lower semiconducting paper of conductance.
Embodiment 2, and using 400 kilograms of concentration is that 5% alcohol water blend permeates 140 kilograms of carbon blacks.1000 kilograms of sulfate true qualities wood pulps beater of packing into is discongested, discongest the back and in time add carbon black with the alcohol infiltration.About 2 hours of the light beating that falls then makes the carbon black firm attachment on fiber.Get to 35 when spending when beating degree, add 70 kilograms of fibrous type polyvinyl alcohol, the making beating temperature is less than 60 ℃, beat when beating degree 45 is spent, add 40 kilograms of cationic starches, when copying paper, add 5 kilograms of weak cation type polyacrylamides at web-roll core case position, can be made into the higher semiconducting paper of conductance.
Embodiment three, and using 330 kilograms of concentration is that 5% alcohol water blend permeates 110 kilograms of carbon blacks.1000 kilograms of sulfate true qualities wood pulps beater of packing into is discongested, discongest the back and in time add carbon black with the alcohol infiltration.About 2 hours of the light beating that falls then when beating degree is 35 when spending, adds 50 kilograms of fibrous type polyvinyl alcohol, and the making beating temperature is less than 60 ℃, beats when beating degree 45 is spent, and adds 30 kilograms of cationic starches.When copying paper, add 3 kilograms of weak cation type polyacrylamides, on a cylinder of the two cylinder paper machines of twin-tub, creping doctor is installed, half-dried wrinkling, the two cylinder oven dry, the speed of two cylinder is suitably adjusted, and produces the bigger semiconductor crepe paper of percentage elongation.
