Abstract
The utility model relates to a polyimide film medium-adhesive-contented mica tape for a generator set coil and belongs to the technical field of insulation. An epoxy adhesive is coated on both sides of mica paper, a non-alkali glass cloth is used as a reinforcing material for one side, and a polyimide film is used as a reinforcing material for the other side, thereby obtaining the polyimide film medium-adhesive-contented mica tape by compounding. The product provided by the utility model has the advantages of moderate flexibility, good tensile strength and excellent electrical performance.
Description
Technical field
The utility model relates to a kind of polyimide film rubber powder mica tape that is used for the generating set coil, belongs to the insulation technology field.
Background technology
Technique of vacuum pressure for dipping electrical (claiming VPI technology again) is the developing direction of large-size machine insulation system.Adopt VPI technology, the insulation system mechanical strength is high, moistureproof ability is strong, excellent electrical properties.There are " middle glue dipping " and " few glue dipping " two big technology paths in domestic VPI technology." few glue dipping " is not used widely because of technology passes a test, and " middle glue dipping " then obtained popularization.Middle rubber powder mica tape is one of key component of " middle glue dipping " technology, and its quality requirement is: mica content is high, electrical strength is high, insulation thickness is thin.
What domestic production was the widest is rubber powder mica tape in the epoxy paulownia horse glass, and it is composited by mica paper, alkali-free glass cloth, adhesive.Alkali-free glass cloth is a supporting material, and the mica paper two sides all is stained with alkali-free glass cloth.Rubber powder mica tape class of insulation F level in this can not be used for the environment that the H level requires.
Summary of the invention
The purpose of the utility model is: rubber powder mica tape in a kind of polyimide film is provided, mica tape class of insulation H level.
The utility model is realized through following technical proposal:
Rubber powder mica tape in a kind of polyimide film comprises mica paper, alkali-free glass cloth, polyimide film and epoxy adhesive.
Said mica paper is quantitatively to be 160 ± 10g/m
2Non-calcinated type mica paper.
Said alkali-free glass cloth, quantitative 22 ± 1g/m
2
Said polyimide film, quantitative 28 ± 1g/m
2
Said epoxy adhesive, consumption are the 30-35% of mica tape gross mass.
Rubber powder mica tape in the said polyimide film, gross thickness 0.14 ± 0.02mm.
Rubber powder mica tape in the said polyimide film, the mica paper two sides all scribbles epoxy adhesive, the one side with alkali-free glass cloth as supporting material, the one side with polyimide film as supporting material.
Rubber powder mica tape in the said polyimide film, disposable compound, the oven dry of mica paper, alkali-free glass cloth, polyimide film, epoxy adhesive forms.
The utility model has the advantages that: as supporting material, promoted insulation property greatly with polyimide film; Rubber powder mica tape softness is moderate in the polyimide film of making, and hot strength is good, electric property is superior.
Description of drawings
Accompanying drawing is the structural representation of rubber powder mica tape in this polyimide film.
Wherein: 1-mica paper, 2-epoxy adhesive, 3-alkali-free glass cloth, 4-polyimide film.
Embodiment
In conjunction with accompanying drawing, the utility model is described.
Rubber powder mica tape in a kind of polyimide film comprises mica paper 1, epoxy adhesive 2, alkali-free glass cloth 3, polyimide film 4.
Mica paper is quantitatively to be 160 ± 10g/m
2Non-calcinated type mica paper.
Alkali-free glass cloth, quantitative 22 ± 1g/m
2
Polyimide film, quantitative 28 ± 1g/m
2
Epoxy adhesive, consumption are the 30-35% of mica tape gross mass.
Rubber powder mica tape in the polyimide film, gross thickness 0.14 ± 0.02mm.
After epoxy adhesive 2 is coated on mica paper 1 two sides, promptly carry out compound with alkali-free glass cloth 3, polyimide film 4; Pass through baking oven again, 110-120 ℃ of control temperature impelled solvent evaporates; After rolling, cut and obtain rubber powder mica tape in the polyimide film.
Rubber powder mica tape in the polyimide film of being produced, class of insulation H level, dielectric constant 60-65MV/m, hot strength 75-80N/10mm.
