Abstract

A kind of MULTILAYER COMPOSITE mica paper, including base material, the base material both sides form the thick lodicule layer of mica and mica screened stock lamella respectively, wherein, the thick lodicule layer of mica is molded directly within the side surface of base material one as element contact surfaces, and one layer of alkali-free glass fiber cloth is then formed between mica screened stock lamella and base material, simultaneously pre- folding line is pressed with centre position of the surface of the thick lodicule layer of the mica along mica paper base material expansion direction, and the mica screened stock sheet surfaces of pre- folding line position correspondence are accounted for by organic insulation silicon resin glue and form one layer of nano level aluminum hydroxide particles layer herein.The utility model can improve the anti-shear performance and fitting compactness of fitting part while performance of mica paper itself is kept, so as to ensure the surface overall performance of whole contact surface.

Description

A kind of MULTILAYER COMPOSITE mica paper

Technical field

It the utility model is related to insulation mica products field, it is specially a kind of to possess the more of higher-strength and tear resistance Layer combined mica paper.

Background technology

Mica is the general name of a kind of hydrous alumino silicates class, has electrical strength by the use of the mica paper that mica is prepared as raw material Height, dielectric loss is low, and sheet resistance and volume resistance are high, has heat resistance, water resistance, chemical stability, high resilience, high stripping From excellent properties such as property, very big fingerprinting stress and tensile strength, application is obtained in many fields.

But it is to be broken into slurry copy paper through heat chemistry or waterpower stripping point that mica paper is mostly in actual application, then through cutting Continuous roll web or sheet-fed, this slurry technique can make the mica flake of particle diameter of all sizes more equal made of technique It is distributed in evenly in the structure of mica paper, its rough surface, tensile strength and hardness are also not satisfactory, on shaping position surface Stretching resistance, anti-shearing force are weak when outer rim or seaming position, and bulk strength is poor, easily ftracture, lead under strong impact force effect Cause edge to warp, ftracture, have impact on the using effect and presentation quality of mica paper.

Utility model content

The technical problem that the utility model solves is to provide a kind of MULTILAYER COMPOSITE mica paper, to solve above-mentioned background skill The shortcomings that in art.

The technical problem that the utility model solves is realized using following technical scheme：

A kind of MULTILAYER COMPOSITE mica paper, including base material, the base material both sides form the thick lodicule layer of mica and cloud respectively Female screened stock lamella, wherein, the thick lodicule layer of mica is molded directly within the side surface of base material one as element contact surfaces, and mica is thin Then form one layer of alkali-free glass fiber cloth between lodicule layer and base material, while on the surface of the thick lodicule layer of the mica along mica The centre position of paper base material expansion direction is pressed with pre- folding line, and the mica screened stock sheet surfaces of pre- folding line position correspondence pass through herein Organic insulation silicon resin glue, which accounts for, forms one layer of nano level aluminum hydroxide particles layer.

In the utility model, the base material is copper-plated graphite piece or Ni-coated graphite piece, and its thickness is 300 ~ 500 μm.

In the utility model, the thickness of the thick lodicule layer of mica is 200 ~ 300 μm, the particle diameter of mica flake therein For the mesh of -10 mesh ~+120.

In the utility model, the thickness of the mica screened stock lamella is 100 ~ 200 μm, the particle diameter of mica flake therein For the mesh of -50 mesh ~+200.

In the utility model, the aluminum hydroxide particles particle diameter filled in the aluminum hydroxide particles layer is 80 ~ 300nm.

In the utility model, aluminum hydroxide particles layer and the glass fabric for being molded over aluminum hydroxide particles layer surface The width of bar is preferably 3 ~ 5 times of pre- folding line width, and no more than the 1/3 of MULTILAYER COMPOSITE mica paper width.

Beneficial effect：The utility model preferably maintains performance of mica paper itself, meanwhile, surface smoothness is high, grain The tensile strength of mica paper can be effectively improved by spending the iterative structure of different double-deck mica flake layers, coordinate pre- folded edges energy Element edge is effectively preferably bonded, prevents mica paper from heaving, be broken and coming off at element edge, to ensure its overall performance.
