Description
Technical field
The utility model is related to insulation mica products field, specially a kind of MULTILAYER COMPOSITE cloud for possessing preferable insulating properties
Female paper.
Background technology
Mica is the general name of a class hydrous alumino silicates class, and it has electrical strength high, and dielectric loss is low, sheet resistance and
Volume resistance is high, with heat resistance, water resistance, chemical stability, high resilience, high fissility, very big fingerprinting stress and anti-
The excellent properties such as Zhang Qiangdu, and mica paper is, using muscovite as raw material, slurry copy paper to be broken into through heat chemistry or waterpower stripping point, then pass through
Continuous roll web or sheet-fed that separating and cutting process is made, are widely used in the electric insulation applications of motor.
And in motor insulation applications, as large-size machine develops to miniaturization, particularly wind-powered electricity generation, nuclear power, high ferro are led
Draw the equipment such as motor require that motor volume is small, dielectric strength is high, it is service life length, safe and reliable, therefore to the matter of mica paper
Amount proposes higher requirement.Production mica paper technique is single at present, more using traditional slurry technological forming, this slurry work
Artistic skill makes the mica flake of particle diameter of all sizes relatively be evenly distributed in the structure of mica paper, its rough surface,
Electrical strength, tensile strength and hardness are also not satisfactory, it is impossible to meet the normal market demand.In addition used in production mica paper
In raw material, the mica of dark color is usually mixed with, the using effect and presentation quality of mica paper is also have impact on.
Utility model content
The technical problem that the utility model is solved is to provide a kind of MULTILAYER COMPOSITE mica paper, to solve above-mentioned background skill
Shortcoming in art.
The technical problem that the utility model is solved is realized using following technical scheme：
A kind of MULTILAYER COMPOSITE mica paper, including base material, wherein, the base material is acetate fibre cloth, this acetate fibre cloth
One layer of polyimide film of side surface forming, and it is uniform filled with one layer of nanoscale between polyimide film and acetate fibre cloth
Aluminium hydroxide or magnesium hydroxide particle layer；And have the female thick lodicule layer of a stratus in the opposite side surface forming of acetate fibre cloth,
And the thick lodicule layer surface of mica is provided with the particle diameter of mica flake in the female screened stock lamella of a stratus, the thick lodicule layer of mica
For the mesh of -10 mesh~+120, and the particle diameter of mica flake is the mesh of -50 mesh~+200 in mica screened stock lamella.
It is used as further improvement of the utility model：
It is 0.05~0.1mm as the acetate fibre cloth thickness of base material, is individual layer or double-deck acetate fibre cloth.
The thickness of the thick lodicule layer of the mica is 1~2 times of mica screened stock lamellar spacing, and the thick lodicule layer of mica and mica
The thickness sum of screened stock lamella is 0.6~0.8mm.
Contact site formation thickness between the thick lodicule layer of mica and mica screened stock lamella is not more than crossing for 0.2mm
Layer, and layer position that cross herein forms one layer of insulating cement.
The mica for preparing the thick lodicule layer of the mica is muscovite, phlogopite or synthetic mica, and prepares the mica
The mica of screened stock lamella is the muscovite that purity is more than 96%.
Beneficial effect：Mica paper of the present utility model has good high temperature resistant electric property, while surface is smooth, screened stock
Lamella and thick lodicule layer are had a style of one's own, and screened stock lamella outside, including thick lodicule layer, the different mica flake of particle is separated, increased
The strong tensile strength of mica paper, meanwhile, the polyimide film of its dorsal part coordinates nm sized hydroxide particles layer effectively to carry
The surface tension of high mica paper so that its finished product both maintained natural mica resist wear, high insulation, it is heat-insulated the advantages of, having has
Preferably electrical strength and stability.
