Description
Technical field
Mica paper arts are the utility model is related to, are specially a kind of high intensity mica for insulation of electrical installation
Band.
Background technology
Mica paper has higher electrical strength and relatively low dielectric loss, while also have resistance to as mica product
Hot, water resistance, chemical stability.And mica tape is to be equipped with appropriate gluing by the supporting material such as mica paper and glass fabric
The insulating materials cut after the baked drying of agent, its electric property with mica paper in itself, while have excellent resistance to
High-temperature behavior and flame resistance energy, and there is good flexibility under normal conditions, available for various fire resisting electromagnetic wire cables, coil
Hot-face insulation liner layer.
But existing mica tape physics defense of resistance to impact grade is low, and function is single, although with certain heat resistance,
Cannot long-time fire resisting, in surrounding environment there are comburant in the case of heat-proof quality it is poor, do not have the effect of high temperature protection,
Tensile strength, hardness and insulation performance are also not satisfactory at the same time, it is difficult to the electrical equipment higher applied to insulating requirements.
Utility model content
The technical problem that the utility model is solved is to provide a kind of high intensity mica tape, and this mica band structure is steady
Calmly, intensity is good, and tensile property is superior, is beneficial to improve the electric property of major insulation, so as to improve the skill of relevant device
Art index, service life and operational reliability, the shortcomings that to solve in above-mentioned background technology.
The technical problem that the utility model is solved is realized using following technical scheme：
A kind of high intensity mica tape, including mica paper layer and answering for its surface is molded over by organosilicon adhesive-layer adhesion
Strengthening course is closed, wherein, the gross thickness of the composite reinforcing layer is 300 ~ 800 μm, and polyester Asia is followed successively by from mica paper layer is laterally outer
Amine layer, alkali-free glass fiber cloth and the ratio between nonwoven layer, the thickness of polyester-imide layer, alkali-free glass fiber cloth and nonwoven layer are 2:1:
1, cellular or form diamond checks through hole is uniformly formed on the polyester-imide layer.
As further improvement of the utility model：
The single hole area of the molding through hole is 50 ~ 120mm on the polyester-imide layer2, and between adjacent through hole
Spacing be 2 ~ 3mm.
The coating thickness of the organosilicon adhesive-layer is 100 ~ 300 μm.
The mica paper layer is double-deck mica paper layer, and two layers of mica paper layer is muscovite paper or synthetic mica paper, two
A layer graphene film layer is formed between layer mica paper, and with being molded a little in the mica paper layer of organosilicon adhesive-layer contact side
Battle array through hole.
Nonwoven cloth in the nonwoven layer preferably uses heat seal non-woven fabrics or melt spraying non-woven fabrics.
The nonwoven layer surface forming has one layer of hot melt adhesive layer, and has one layer in its surface forming by this hot melt adhesive layer
Release film.
Beneficial effect：The utility model is heat-resist, and adhesive strength is high, and tensile strength is high, while also prevents with higher
Fire and waterproofing grade, be conducive to improve major insulation electric property so that improve the technical indicator of electrical equipment, service life and
Operational reliability.
