Abstract
The utility model discloses a kind of heat resistant epoxide resin prepreg cloth, including polyester film and polyester fibre nonwoven fabric composite flexible material layer, upper and lower surface all homogeneous impregnations of the polyester film and polyester fibre nonwoven fabric composite flexible material layer have heat resistant epoxide resin layer；The utility model can substitute the pre-soaked resin adhesive-bonded fabric of import heat resistant epoxide resin adhesive-bonded fabric, have the advantages of relatively low cost, superior performance.
Description
Technical field
The utility model belongs to insulating materials technical field, is related to a kind of epoxy resin preimpregnation cloth, and in particular to Yi Zhongnai
Hot epoxy resin prepreg cloth.
Background technology
Heat resistant epoxide resin prepreg cloth is widely used in low-voltage coil of dry type transformer layer insulation and F level motor slot insulation
And phase insulation, but the pre-soaked resin adhesive-bonded fabric cost of present used import heat resistant epoxide resin adhesive-bonded fabric is higher.
Utility model content
The purpose of this utility model is for overcome the deficiencies in the prior art, and provides that a kind of cost is relatively low, superior performance
Heat resistant epoxide resin prepreg cloth.
What the purpose of this utility model was realized in：A kind of heat resistant epoxide resin prepreg cloth, including polyester film polyester
Fiber nonwoven fabric composite flexible material layer, the upper and lower surface of the polyester film and polyester fibre nonwoven fabric composite flexible material layer
All homogeneous impregnation has heat resistant epoxide resin layer.
Preferably, the heat resistant epoxide resin layer is novolac epoxy resin.
Preferably, the thickness of the heat resistant epoxide resin prepreg cloth is 0.1mm~0.6mm.
Preferably, the width of the heat resistant epoxide resin prepreg cloth is 5mm~1000mm.
By adopting the above-described technical solution, the beneficial effects of the utility model are：Using technology maturation, lower-cost
Polyester film and polyester fibre nonwoven fabric composite flexible material layer, by its outer surface homogeneous impregnation heat resistant epoxide resin layer, coming
The pre-soaked resin adhesive-bonded fabric of existing import heat resistant epoxide resin adhesive-bonded fabric is substituted, it is exhausted for low-voltage coil of dry type transformer interlayer
Edge and F level motor slot insulation and phase insulation, cost are minimized, while have excellent electric property, heat resistance, fire-retardant
Property, at room temperature storage period grow.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the present utility model.
In figure：1st, polyester film and polyester fibre nonwoven fabric composite flexible material layer 2, heat resistant epoxide resin layer.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in figure 1, a kind of heat resistant epoxide resin prepreg cloth provided by the utility model, including polyester film and polyester fibre
Nonwoven fabric composite flexible material layer 1, it is gluing that polyester film and polyester fibre nonwoven fabric composite flexible material layer is that polyester film is coated with
The 3-layer composite material that agent, two sides bonded polyester fiber nonwoven fabric form, technology maturation, cost is low, and has good dielectric
Performance and mechanical property, high tensile force resistance and heat resistance, it is exhausted to make slot insulation, pad insulation and turn-to-turn suitable for B levels motor, electrical equipment
Edge.Upper and lower surface all homogeneous impregnations of the polyester film and polyester fibre nonwoven fabric composite flexible material layer 1 have heat-resistant rings oxygen tree
Lipid layer 2, it is impregnated with the polyester film and polyester fibre nonwoven fabric composite flexible material layer 1 of heat resistant epoxide resin layer 2, its electrical resistance
Energy, heat resistance and anti-flammability are improved, and while cost is also minimized, can substitute existing import heat-resisting completely
The pre-soaked resin adhesive-bonded fabric of epoxy resin adhesive-bonded fabric, for low-voltage coil of dry type transformer layer insulation and F level motor slot insulation
And phase insulation.
Further, the heat resistant epoxide resin layer 2 is novolac epoxy resin, and novolac epoxy resin is also known as F type ring oxygen trees
Fat, its epoxy group content is high, and viscosity is larger, and solidified after-product crosslink density is high, and its fibre reinforced plastics has good physics
Mechanical performance.
Further, the thickness of the heat resistant epoxide resin prepreg cloth is 0.1mm~0.6mm.
Further, the width of the heat resistant epoxide resin prepreg cloth is 5mm~1000mm, and the heat resistant epoxide resin is pre-
Leaching cloth is typically produced as coiled material.
Here is every technical performance index of the present utility model：
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than its limitations,
Although the utility model is described in detail with reference to above-described embodiment, those of ordinary skill in the art should manage
Solution, can still modify or equivalent substitution to specific embodiment of the present utility model, and without departing from the utility model
Any modification of spirit and scope or equivalent substitution, it all should cover among right of the present utility model.
