Abstract
The invention discloses mica paper, belonging to the field of insulating material preparation. The mica paper is prepared from the following raw materials in parts by weight: 120-130 parts of mica, 10-15 parts of aramid fibers, 1-2 parts of gelatin, 4-6 parts of polyvinyl alcohol, 2-3 parts of PAE wet strength agent, 5-10 parts of bamboo charcoal powder, 2-3 parts of aluminium hydroxide, 1-2 parts of boric acid, 1-2 parts of sodium persulfate, 1-2 parts of soybean oil, 4-5 parts of acrylic emulsion and a proper amount of water. The invention also discloses a production method of the mica paper. The mica paper and the production method have the beneficial effects that the excellent characteristics of fibers and mica are integrated, the surface adhesion of new lodicules in the mica paper production process is obviously improved, the tension during mica paper production is improved, paper breaking during manufacturing paper with pulp is reduced, the production cost is effectively reduced, and the advantages of puncture resistance, high insulativity, heat insulation and the like of natural mica are maintained; the prepared mica paper has good electric strength and tensile strength.
Description
?
Technical field
The present invention relates to a kind of mica paper and production method, the particularly mica paper of a kind of tension and good insulation preformance and production method, belongs to insulating material and manufactures field.
Background technology
Mica is a kind of general name of hydrous alumino silicates class, it is high that it has electrical strength, dielectric loss is low, surface resistivity and volume resistance are high, there is thermotolerance, water tolerance, chemical stability, high resilience, high separability, the very large excellent properties such as fingerprinting stress and tensile strength, be widely used at present motor electric insulation field.
Along with large-size machine develops to miniaturization, particularly the equipment such as wind-powered electricity generation, nuclear power, high ferro traction electric machine all requires that motor volume is little, insulation strength is high, long service life, safe and reliable, therefore the quality of mica paper is had higher requirement.Produce at present mica paper technique single, electrical strength, tensile strength and the hardness of mica paper are all undesirable, cannot meet the normal market requirement.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned defect, provides that a kind of pull resistance is strong, mica paper and the production method of insulativity.
In order to solve the problems of the technologies described above, the invention provides a kind of mica paper, it is made up of the raw material of following weight part:
130 parts of mica 120-
Aramid fiber 10-15 part
Gelatin 1-2 part
Polyvinyl alcohol 4-6 part
PAE Wet Strength Resin 2-3 part
Bamboo charcoal powder 5-10 part
Aluminium hydroxide 2-3 part
Boric acid 1-2 part
Sodium Persulfate 1-2 part
Soybean oil 1-2 part
ACRYLIC EMULSION 4-5 part
Water is appropriate.
The present invention also provides the production method of above-mentioned mica paper, comprises the following steps:
1), by mica high-temperature calcination at 700-800 DEG C, calcine 90-120 minute to such an extent that become to make mica magma after mica grog, and mica magma sent into the stock tank of manufacturing paper with pulp;
2), just aramid fiber disperses in water, making its mass concentration is 35-45%;
3), by all the other the raw material mixing and water addings except bamboo charcoal powder, to water content be 20-30%, be heated to 80-90 DEG C, stirring reaction 40-60 minute;
4), by bamboo charcoal powder, step 2) scattered aramid fiber and step 3) mixing solutions that mixes joins and manufactures paper with pulp in stock tank, stirring reaction 80-120 minute;
5), cylinder copy paper drying after forming is to water content 0.2-0.5%, obtains mica paper.
Beneficial effect of the present invention is: the present invention combines the good characteristic of fiber and this bi-material of mica, significantly improve newborn lodicule surface adhesion force in mica paper production process, pulling force while obviously improving mica paper production, reduce the disconnected paper while manufacturing paper with pulp, effectively reduce production costs, kept again natural mica to resist wearing, high insulation, the advantage such as heat insulation, mica paper electrical strength and tensile strength that it makes are good.
