Abstract
The utility model discloses a polyimide and polyester fiber non-woven fabric combined insulating material and a wire cable formed by the same, and aims to provide an insulating material and a wire cable formed by the same, wherein the insulating material can lead insulating resin materials to be evenly coated on a film surface made of polyimide insulating materials and is fine in seal effect and insulating effect. The insulating material consists of a polyimide insulating layer and a polyester fiber non-woven fabric layer, and the polyimide insulating layer is connected with the polyester fiber non-woven fabric layer via a polyurethane adhesive layer. The wire cable consists of a wire cable metallic core, a polyimide insulating layer and a resin insulating layer are wrapped outside the wire cable metallic core, a polyester fiber non-woven fabric layer is disposed between the polyimide insulating layer and the resin insulating later, and the polyimide insulating layer is connected with the polyester fiber non-woven fabric later via a polyurethane adhesive layer. The insulating material and the wire cable formed by the same can greatly reduce accidents caused by breakdown of polyimide insulating material films due to external reasons, and increase electricity using ratio.
Description
Technical field
The utility model relates to the cable of a kind of insulating material and composition thereof, in particular, relates to the cable of a kind of polyimides and polyester fiber nonwoven fabrics combined insulation material and composition thereof.
Background technology
In the last few years along with the development of China's all our undertakings, electricity become our all our undertakings development the indispensable energy.Along with the development of China's electric utility, as a part in the electric utility, it is most important that insulating material more seems.The effect of insulating material is in electric equipment the different live part of electromotive force to be kept apart.Therefore insulating material should have higher insulation resistance and compressive resistance, and can avoid leaking electricity, accident such as puncture.
Along with the raising of electrical equipment serviceability, also more and more higher to the requirement of insulating material wherein, the insulating material that some lower grades can not use in some electrical equipment.At present, the polyimide foam insulation film is owing to have good thermal endurance, dielectricity, mechanicalness, oil resistance and ageing resistance, anti-marginal laceration, radiation resistance etc., and be applicable under acid and the neutrallty condition, be widely used as the H class F insulating material F.But, in use find, the polyimide foam insulation film is being twined the cable metal core, and after the polyimide foam insulation thin film exterior layer is coated insulating resin and is sealed, because individual layer polyimide foam insulation film surface is smooth, insulating resin can not thoroughly be coated in the polyimide foam insulation film surface uniformly, make part polyimide foam insulation film exposed outside, can not reach good obturation effect, not tight can occur arranging between line and the line after the wire winding in motor, make wherein to produce the slit, the vortex of heat occurs, reduced electric utilization rate.And, after the long-time use of cable,, cause short circuit, even cause fire because outside cause can cause the polyimide foam insulation film breakdown, cause certain loss to the user.
The utility model content
The utility model is in order to overcome weak point of the prior art, provide a kind of dielectric resin material that can make to be coated in the polyimide foam insulation film surface uniformly, good sealing effect, insulation effect is good, can reduce the breakdown accident that causes of polyimide foam insulation film, the cable of the polyimides of long service life and polyester fiber nonwoven fabrics combined insulation material and composition thereof.
The utility model is achieved through the following technical solutions:
A kind of polyimides and polyester fiber nonwoven fabrics combined insulation material is characterized in that, comprise polyimide insulative layer and polyester fiber nonwoven layer, are connected by the adhesive for polyurethane layer between described polyimide insulative layer and the polyester fiber nonwoven layer.The thickness of described polyester fiber nonwoven layer is 0.05-0.1mm; The thickness of adhesive for polyurethane layer is 0.002-0.005mm.
A kind of cable of forming by polyimides and polyester fiber nonwoven fabrics combined insulation material, comprise that cable is metal-cored, the metal-cored external packets of described cable is covered with polyimide insulative layer and resin insulating barrier, it is characterized in that, between polyimide insulative layer and resin insulating barrier, be provided with the polyester fiber nonwoven layer, be connected by the adhesive for polyurethane layer between described polyimide insulative layer and the polyester fiber nonwoven layer.The thickness of described polyester fiber nonwoven layer is 0.05-0.1mm; The thickness of described adhesive for polyurethane layer is 0.002-0.005mm.
The utlity model has following technique effect:
Insulating material of the present utility model is to be combined by polyimides and polyester fiber nonwoven fabrics, and product had both kept the advantage of polyimide insulative film, has added the coarse characteristics of polyester fiber nonwoven surface again.When using insulating material of the present utility model to form cable, because the polyester fiber nonwoven surface is coarse, when the casting insulated resin of outermost layer, can make insulating resin be coated in the polyester fiber nonwoven surface uniformly, thereby reach good sealing effect, improved the insulation effect of cable, significantly reduced because the breakdown accident that causes of polyimide foam insulation film that outside cause took place, prolong the useful life of cable, and increased electric utilization rate.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the structural representation of the utility model polyimides and polyester fiber nonwoven fabrics combined insulation material, comprise polyimide insulative layer 1 and polyester fiber nonwoven layer 3, be connected by adhesive for polyurethane layer 2 between described polyimide insulative layer 1 and the polyester fiber nonwoven layer 3.Wherein, the thickness of described polyester fiber nonwoven layer is generally 0.05-0.1mm, and the thickness of described adhesive for polyurethane layer is generally 0.002-0.005mm, and the thickness of polyimide insulative layer is determined according to customer requirements.
Fig. 2 is the structural representation of the cable of polyimides and polyester fiber nonwoven fabrics combined insulation material composition, comprise cable metal-cored 5, the external packets of cable metal-cored 5 is covered with polyimide insulative layer 1 and resin insulating barrier 4, between polyimide insulative layer 1 and resin insulating barrier 4, be provided with polyester fiber nonwoven layer 3, be connected by adhesive for polyurethane layer 2 between polyimide insulative layer 1 and the polyester fiber nonwoven layer 3.
During production, be coated with the adhesive for polyurethane layer in the one side of polyimide insulative layer, sticking again one deck polyester fiber nonwoven layer is formed polyimides and polyester fiber nonwoven fabrics combined insulation material.After this insulating material is wrapped in that cable is metal-cored and goes up,, can obtain the cable of polyimides and polyester fiber nonwoven fabrics combined insulation material composition at the casting insulated again resin in polyester fiber nonwoven layer outside.Because the polyester fiber nonwoven surface is coarse, can make insulating resin be coated in its surface uniformly and reach good sealing effect.Significantly reduced owing to the puncture short phenomenon that outside cause took place, and increased electric utilization rate.
