Abstract

The utility model discloses a fire resistance mica belt, it includes insulation protective layer, mica layer and glass -bonded mica fibrous layer, insulation protective layer, mica layer and glass -bonded mica fibrous layer are according to laminating in proper order from last order under to, the utility model discloses structural design is ingenious, reasonable, covers to have closed insulation protective layer, is favorable to putting forward the high insulating ability to improve electrical equipment's technical indicator, running life and operational reliability, do not need to cover in addition again the insulating layer when using mica tape winding electric wire, motor or other parts simultaneously, and then saved the cost, practiced thrift manpower and resource, adopting the glass -bonded mica fibrous layer, effectively increasing the content of mica, effectively improve the fire -resistant insulating properties of whole of mica tape, comprehensive properties is good, and overall structure is succinct in addition, realizes easily that the practicality is strong, does benefit to extensive popularization and application.

Description

Fire-resistant isinglass belt
Technical field
The utility model relates to mica tape technical field, particularly a kind of fire-resistant isinglass belt.
Background technology
Economic fast development, the market demand of cable grows with each passing day.And cable produce in commonly use refractory insulating material be mica tape, the quality of refractory insulating material directly or indirectly affects the serviceability of cable.Mica tape on existing market, bond post-drying primarily of layer of glass cloth and one deck mica to make, there is excellent resistance to elevated temperatures and flame resistance energy, during mica tape normality, there is good flexibility, be applicable to main refractory insulating layer in various fire-resistant wire and cable.
But existing mica tape is limited to design itself problem, its fire resistance and insulation property not ideal, be difficult to be applied to the electrical equipment higher to insulating requirements.
Utility model content
For above-mentioned deficiency, the utility model object is to provide a kind of smart structural design, rationally, fire resistance and insulation property preferably fire-resistant isinglass belt.
The utility model for achieving the above object; the technical scheme provided is: a kind of fire-resistant isinglass belt; it comprises insulating protective layer, mica layer and glass bonded mica fibrage; described insulating protective layer, mica layer and glass bonded mica fibrage are fitted successively according to order from top to bottom, and described insulating protective layer is the one in PE film, PET film, pen film, pvdf membrane, PTFE film.
Improve as one of the present utility model, its thickness is 0.1 ~ 0.2 millimeter.The thickness of described insulating protective layer is 0.01 ~ 0.02 millimeter.The thickness of described mica layer is 0.03 ~ 0.05 millimeter.The fibrolaminar thickness of described glass bonded mica is 0.03 ~ 0.05 millimeter.
Improve as one of the present utility model, adhesive-layer laminating on the outer surface of described insulating protective layer.
The beneficial effects of the utility model are: the utility model smart structural design, rationally, laminating have insulating protective layer, are conducive to improving insulation property, thus improve the technical indicator of electric equipment, service life and operational reliability; Do not need to cover insulating barrier in addition again when using mica tape wound wire, motor or other part simultaneously, and then provide cost savings, saved manpower and resource; Adopt glass bonded mica fibrage, effectively increase the content of mica, effectively improve the overall hot-face insulation performance of mica tape, good combination property, in addition terminal with compact integral structure, be easy to realize, practical, be beneficial to wide popularization and application.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
Embodiment: see Fig. 1; the utility model embodiment provides a kind of fire-resistant isinglass belt; it comprises insulating protective layer 1, mica layer 2 and glass bonded mica fibrage; described insulating protective layer 1, mica layer 2 and glass bonded mica fibrage 3 are fitted successively according to order from top to bottom, and described insulating protective layer 1 can be the one in PE film, PET film, pen film, pvdf membrane, PTFE film.Be preferably pen film, pvdf membrane or PTFE film.
During making, in advance glass fabric is immersed in mica slurry, makes mica starch sufficient immersion in glass fabric, and fill up the square aperture on glass fabric, form mica layer 2 at the outer surface of glass fabric simultaneously, and then obtained glass bonded mica fibrage 3; Namely this glass bonded mica fibrage 3 comprises by from stacked successively upper mica layer, fiberglass cloth and the lower mica layer of upper order at least, square aperture wherein on fiberglass cloth is filled with mica, and then increase the content of mica, the overall hot-face insulation performance of effective raising mica tape, good combination property.
Preferably, the thickness of the utility model fire-resistant isinglass belt is 0.1 ~ 0.2 millimeter, is preferably 0.1 millimeter, 0.12 millimeter, 0.14 millimeter, 0.17 millimeter, 0.2 millimeter.Wherein, the preferred thickness of described insulating protective layer 1 is 0.01 ~ 0.02 millimeter.The thickness of described mica layer 2 is preferably 0.03 ~ 0.05 millimeter.The thickness of described glass bonded mica fibrage 3 is preferably 0.03 ~ 0.05 millimeter.
In addition, adhesive-layer that can also be laminating on the outer surface of described insulating protective layer 1.Like this, in winding process, effectively promote fastness, not easily occur phenomenons such as loosening, come off, good operating stability.
During use, there are insulating protective layer 1 and glass bonded mica fibrage 3 due to laminating, are conducive to improving insulation property and fire resistance, good combination property, thus the technical indicator of raising electric equipment, service life and operational reliability.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model, adopt other belt body same or analogous with it, all in the utility model protection range.
