Description
Technical field
The utility model belongs to stack bus bar technical field, is related to a kind of single-sided insulation glue film and the lamination mother comprising it
Row.
Background technique
Stack bus bar is a kind of modularization connection row with multi-layer compound structure, by two or more layers strap with absolutely
Edge material bonding encapsulates, and carries out electrical isolation with insulating materials between conductor material layer and layer, leads between adjacent conductor opposite
Electric current, magnetic field cancels out each other, and can reduce system inductance, improves system reliability, and can effectively save installation space.At present
It is mainly used in the fields such as electron electric power, communication, system performance can be significantly improved, and overall cost can be reduced.
The raw material of production stack bus bar mainly have conductor material and insulating materials, and conductor material generally uses tin plating copper
Plate or aluminium sheet, insulating materials then use insulated rubber film.Insulated rubber film primarily serves the effect of insulation, bonding, isolation and protection.Absolutely
Edge glue film can be divided into single side glue film and two-sided glue film by coated face, mainly in the macromolecule membranes such as PET, PBT, PI surface single side
Or one layer of adhesive of dual coating is made.Single side glue film mainly plays the role of bonding, insulation and protection to outermost side conductor；
Two-sided glue film is then to play the role of bonding, insulation and isolation between adjacent conductor.Stack bus bar usually passes to high current,
For operating voltage more than thousands of volts, operating temperature is also much higher than room temperature, therefore, very high to flame-retardancy requirements, general to require
Reach V-0 grades or more.The conductors such as copper, aluminium material cannot generally burn in air, and the anti-flammability of insulated rubber film is poor, in sky
It can burn in gas, especially single side glue film only has a face adhesive coating layer, and another side exposes in air, to flame-retardancy requirements
It is higher.Therefore, the anti-flammability of stack bus bar is improved, the anti-flammability of insulated rubber film is mainly improved.Insulated rubber film is mainly by height
Molecular film and gluing oxidant layer composition, moreover, because the machine-shaping of stack bus bar requires, macromolecule membrane thickness generally exists
100 μm or more, the thickness of gluing oxidant layer is at 40 μm or less.Macromolecule membrane is usually more demanding to physical mechanical property, can not
Anti-flammability is improved by a large amount of fire retardants are added；And gluing oxidant layer is inherently thinner than macromolecule membrane layer, performance requirement is also very
Height, development difficulty is very big, if adding a large amount of fire retardants to improve flame retardant property, certainly will reduce other performances of adhesive, from
And it is unable to satisfy the bonding and insulating requirements of stack bus bar.Therefore, the anti-flammability for how improving insulated rubber film becomes raising lamination
The safety and reliability institute urgent problem to be solved of busbar.
205380955 U of CN discloses a kind of white insulated rubber film of stack bus bar, including is set in turn in described outermost
The first adhesive layer, ontology macromolecule membrane, the second adhesive layer except side conductor and the white macromolecule membrane with covering power.
The stack bus bar insulated rubber film is realized white appearance, is led with reaching shading and protection while with good weatherability
The purpose of the internal structure of body, however its insulated rubber film is dual coating adhesive, there is no solve to improve single-sided insulation glue film
Anti-flammability the problem of.
