Abstract
The utility model discloses an epoxy glass cloth polyester fiber non-woven fabric dry mica tape, which comprises mica paper, wherein the upper surface of the mica paper is bonded with alkali-free glass cloth through an adhesive, and the lower surface of the mica paper is bonded with polyester fiber non-woven fabric through the adhesive; the utility model discloses a polyester fiber non-woven fabrics that electrical property is good, low price as the reinforcement material of few gluey powder mica tape, has improved the tensile strength of powder mica tape effectively.
Description
Technical field
The utility model relates to a kind of epoxy glass fabric polyester fiber nonwoven fabrics dry mica paper tape, belongs to the few glue VPI technology insulation technology field of mesohigh motor coil.
Background technology
The main body insulating material of the few glue VPI technology insulation system of F level mesohigh motor coil is a dry mica paper tape.The supporting material that present domestic dry mica paper tape adopted is generally single face electrician alkali-free glass cloth or single-face polyester film, in use exists hot strength low, the expensive defective of EW type electrician alkali-free glass cloth.
Along with the fierceness day by day of motor market competition, guaranteeing that under motor product steady quality and the reliable premise, the manufacturing cost that reduces motor product has great economic worth.
Summary of the invention
The utility model purpose is: at the prior art deficiency, a kind of epoxy glass fabric polyester fiber nonwoven fabrics dry mica paper tape is provided, it adopts excellent electrical properties, cheap polyester fiber nonwoven fabrics, as the supporting material of dry mica paper tape, improved the hot strength of mica paper tape effectively.
The technical solution of the utility model is: a kind of epoxy glass fabric polyester fiber nonwoven fabrics dry mica paper tape, comprise mica paper, and the upper surface of mica paper is bonded with alkali-free glass cloth through adhesive, and the lower surface of mica paper is bonded with the polyester fiber nonwoven fabrics through adhesive.
The further technical scheme of the utility model is: a kind of epoxy glass fabric polyester fiber nonwoven fabrics dry mica paper tape, comprise mica paper, the upper surface of mica paper is bonded with alkali-free glass cloth through adhesive, and the lower surface of mica paper is bonded with the polyester fiber nonwoven fabrics through adhesive; Above-mentioned mica paper is 507 non-calcinated type mica papers, quantitatively is 120 ± 10g/m
2Above-mentioned alkali-free glass cloth quantitatively is 28 ± 3g/m
2Above-mentioned polyester fiber nonwoven fabrics quantitatively is 30 ± 5g/m
2Above-mentioned adhesive is an epoxyn, and when the dry mica paper tape gross thickness was 0.17 ± 0.02mm specification, adhesive content was 13～17% of mica paper tape gross mass.
The utility model advantage is: the utility model adopts excellent electrical properties, cheap polyester fiber nonwoven fabrics, as the supporting material of dry mica paper tape, has improved the hot strength of mica paper tape effectively.The polyester fiber nonwoven fabrics belongs to cellular structure, easily floods, and the VPI resin permeates easily, fills; the coil insulation good integrity adopts two-sided reinforcement, protects mica paper effectively in the wrapped process of coil; the mica structure is not subjected to outside destroy, and electrical insulation properties does not reduce.Material cost through measuring and calculating epoxy glass fabric polyester fiber nonwoven fabrics dry mica paper tape has only 80% of epoxy glass fabric dry mica paper tape.
