Abstract
The utility model discloses an epoxy boron amine polyester film mica tape with little colloid meal, including mica paper; the upper surface and the lower surface of the mica paper are respectively combined with an electrotechnical polyester film by an adhesive, thus a meal mica paper can be effectively protected from being damaged in the use process, and the electrical strength and corona-resistance property of wrapping insulation can be improved.
Description
Technical field
The utility model relates to a kind of epoxy boron amide polyester film dry mica paper tape, belongs to F level (155 ℃) electromagnetic wire lapped insulation technical field.
Background technology
Along with the development of electric insulation technology, more and more higher to the requirement of insulating material, the material that performance is single is difficult to satisfy the designing requirement of high-performance electric product.Composite material is exactly a kind of heterogeneous material that the component material by two or more different performance, different shape combines by composite means.Composite material is compared with traditional material, and distinguishing feature has designability exactly.Multiple performances such as the machinery of composite material, heat-resisting, dielectric all can by the selection and the means such as coupling and interfacial adhesion of component material, accomplish the end in view to greatest extent by the instructions for use of product.At present to adopt structure with mica paper tape be two-layer or three-decker to electric insulation, and the kind of layers of material is according to instructions for use and different.Owing to adopt different combination of materials and material thickness, will obtain thermal endurance class, physical and mechanical properties and the different mica paper tape composite product of electric property.
The insulating material of the employing of electromagnetic wire lapped insulation structure has the electrician to use polyester film, polyimide film, single-face polyester film reinforcement or glass cloth reinforcement dry mica paper tape usually.It is wrapped that the prior art weak point is only to use polyester film, thermal endurance class low (130 ℃ of B levels), and corona-resistance property is poor; Single-face polyester film reinforcement or single face glass cloth reinforcement dry mica paper tape, because mica paper exposes on the tep reel surface, the mica paper quality is loose, tear-proof and puncture property are poor, and be damaged easily in use, influences electrical insulation properties.EW type electrician's alkali-free glass cloth and polyimide film, high comprehensive performance, but cost an arm and a leg.
Summary of the invention
The utility model purpose is: a kind of epoxy boron amide polyester film dry mica paper tape is provided; adopt excellent electrical properties, low, cheap two-layer up and down the supporting material of polyester film (PET film) of moisture absorption as dry mica paper tape; with 507 non-calcinated type mica papers is the intermediate layer; bonding between layer and the layer with F level phenolic aldehyde epoxy boron amide adhesive; protect mica paper in use not to be subjected to breakage effectively, improved the electrical strength and the corona-resistance property of lapped insulation.
The technical solution of the utility model is: a kind of epoxy boron amide polyester film dry mica paper tape, comprise mica paper, and the upper surface of mica paper and lower surface are compounded with the electrician through adhesive respectively and use polyester film;
Above-mentioned mica paper is 507 non-calcinated type mica papers, thickness 0.04mm, quantitative 70 ± 6g/m
2
Above-mentioned adhesive is a F level phenolic aldehyde epoxy boron amide adhesive, latent curing agent is 594 boron amide curing agent in the adhesive, when the dry mica paper tape gross thickness was 0.08 ± 0.02mm, 0.10 ± 0.02mm specification, adhesive content was the 3-9% of mica paper tape gross mass.
The utility model advantage is: the utility model discloses a kind of by phenolic aldehyde epoxy boron amide glue bond 507 non-calcinated type mica paper, two-sided is the dry mica paper tape of supporting material with polyester film with the electrician, composite construction is reasonable, each material property is had complementary advantages, and compared with prior art, electrical insulation properties is good, guaranteed that mica insulation layer cloth is subjected to outside destroy, electrical insulation properties is good, and corona-resistance property is good, is applicable to F level (155 ℃) electromagnetic wire lapped insulation structure.

Fig. 1 is a structural representation of the present utility model.
Wherein: 1 mica paper; 2 electricians use polyester film.
Embodiment
Embodiment: as shown in Figure 1, a kind of epoxy boron amide polyester film dry mica paper tape comprises mica paper 1, and the upper surface of mica paper 1 and lower surface are compounded with the electrician through adhesive respectively and use polyester film 2.
Above-mentioned mica paper 1 is 507 non-calcinated type mica papers, thickness 0.04mm, quantitative 70 ± 6g/m
2
Above-mentioned adhesive is a F level phenolic aldehyde epoxy boron amide adhesive, latent curing agent is 594 boron amide curing agent in the adhesive, when the dry mica paper tape gross thickness was 0.08 ± 0.02mm, 0.10 ± 0.02mm specification, adhesive content was the 3-9% of mica paper tape gross mass.
Manufacture process of the present utility model is as follows: it is basic identical to implement production process and common expoxy glass dry mica paper tape, may further comprise the steps: respectively the 0.019mm of lower floor (or 0.015mm) electrician is used polyester film 2, after upper strata 0.015mm electrician is coated with phenolic aldehyde epoxy boron amide glue with polyester film 2 single faces, be bonded together by composite roll with the non-calcinated type mica paper of 0.04mm 507 1, forming levels is polyester film 2, the centre is the three-layer composite structure of mica paper 1, enter the compounding machine drying tunnel, stoving temperature is 130-150 ℃, remove and desolvate, through rolling, cut and form strip material.
Attached technical indicator:
The utility model adopts excellent electrical properties, low, the cheap two-layer up and down supporting material as dry mica paper tape of polyester film 2 (PET film) of moisture absorption; with 507 non-calcinated type mica papers 1 is the intermediate layer; bonding between layer and the layer with F level phenolic aldehyde epoxy boron amide adhesive; protect mica paper in use not to be subjected to breakage effectively, improved the electrical strength and the corona-resistance property of lapped insulation.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
