Abstract
The invention discloses a composite insulating material and a processing method thereof. The composite insulating material has a double-layer structure formed by a surface layer of epoxy glass-cloth and an inner layer of NOMEX insulated paper which are stuck together. The processing method comprises the following steps that: the moisture-eliminated NOMEX insulated paper with the necessary size and an epoxy prepreg are lapped between a steel plate with release paper, the steel plate is heated and pressurized to ensure that the epoxy prepreg is solidified into the epoxy glass-cloth with the functions of moisture protection and protection, the NOMEX insulated paper and the epoxy glass-cloth are stuck to form the needful composite insulating material. The composite insulating material has the advantages of both the NOMEX insulated paper and the epoxy glass-cloth, that is not only has good insulating performance of the NOMEX insulated paper but also has washable property of the glass-cloth and has the characteristics of good moisture protection and certain bending performance, thereby further improving the insulating and pressure-proof performance of the product.
Description
Technical field
The present invention relates to a kind of composite insulating material and processing method thereof, in particular for the insulating material of bus bar surface insulation.
Background technology
The NOMEX insulating paper has good stability, and resistance to elevated temperatures is good, is exactly easy moisture absorption and deformation but NOMEX paper has a shortcoming, and costs an arm and a leg.Usually bus bar surface insulation generally all uses the NOMEX insulating paper.Because the easy moisture absorption of NOMEX insulating paper, local bubbling layering can take place after a period of time, easier this kind of generation situation under high humidity environment influences the insulation property on busbar surface.
The epoxy prepreg is a glass cloth dipping epoxy glue, through the not completely crued gluing flaky material of temperature control baking formation.After heating again, this epoxy glue that is coated with on the film can liquefy and full solidification again, becomes epoxy glass fabric after the curing.Epoxy glass fabric has good moisture-proof role, pliability and intensity preferably, and still, it is not suitable for separately as insulating material.
Summary of the invention
The object of the present invention is to provide a kind of moisture absorption of preventing effect that has, the dielectric voltage withstand performance is good, the composite insulating material that structural strength is good.
Another goal of the invention of the present invention provides the processing method of described composite insulating material, and this method is easy to process, the production efficiency height.
First purpose of the present invention is achieved through the following technical solutions:
The present invention's composite insulating material adopts double-decker, comprises surface layer epoxy glass fabric, nexine NOMEX insulating paper, and NOMEX insulating paper and epoxy glass fabric closely bond the formation adhesive layer.
The thickness of epoxy glass fabric generally is advisable at 0.05mm～0.2mm.
When this composite insulating material was used, a side of band glass cloth to play protection against the tide and protective effect, had certain pliability as superficial layer simultaneously.
The processing method of the present invention's composite insulating material may further comprise the steps:
(1) blanking, the NOMEX insulating paper of cutting required size and the epoxy semifastening sheet that mates with NOMEX insulating paper sheet material;
(2) tide is removed in the baking of NOMEX insulating paper;
(3) patrix will go NOMEX insulating paper and epoxy prepreg behind the tide to overlay between the steel plate of release liners;
(4), make the epoxy prepreg solidify to form the epoxy glass fabric that can moistureproof shield, the composite insulating material that the bonding formation of NOMEX insulating paper and epoxy glass fabric is required to the steel plate pressurization of heating;
(5) with steel plate cooling back mould unloading.
Composite insulating material of the present invention combines the advantage of NOMEX insulating paper and epoxy glass fabric, both kept NOMEX insulating paper good insulation performance performance, it is capable of washing to possess glass cloth surface again, have the characteristics of good moisture-proof role and certain flexural property, product dielectric voltage withstand performance is further promoted.The processing method of composite insulating material is simple, convenient, the production efficiency height.
The invention will be further described below in conjunction with accompanying drawing.

The processing method of the present invention's composite insulating material (referring to Fig. 2) may further comprise the steps:
(1) blanking, the NOMEX insulating paper 3 of cutting required size and the epoxy semifastening sheet 4 that mates with NOMEX insulating paper sheet material;
(2) NOMEX insulating paper 3 is toasted under 90～150 ℃ of temperature remove tide, actual temp can be adjusted according to the equipment effect;
(3) patrix is between the steel plate 6 that goes NOMEX insulating paper 3 behind the tide and epoxy prepreg 4 to overlay release liners 5;
(4) to steel plate 6 pressurization of heating, pressure and temperature determines according to material behavior, for the epoxy prepreg, can use 130～175 ℃ of temperature, pressure 15～25Kg/cm
2, make epoxy prepreg 4 solidify to form the epoxy glass fabric that can moistureproof shield, NOMEX insulating paper 3 and the required composite insulating material of the bonding formation of epoxy glass fabric;
(5) with steel plate 6 cooling back mould unloadings.
The situation of composite insulating material product 7 uses of the present invention on busbar 8 as shown in Figure 3 and Figure 4; busbar 8 the two sides be coated with composite insulating material product 7; the one side of product 7 band oxygen glass cloth 1 toward the outer side; play the moisture protection effect; has certain pliability simultaneously, as product bending position 9.
