Abstract
The utility model relates to a glass preimpregnated fabric, which comprises an alkali-free glass fiber fabric layer, and a heat-resistant epoxy resin layer is uniformly applied on one surface of the alkali-free glass fiber fabric layer. Since the glass preimpregnated fabric is provided with the heat-resistant epoxy resin layer, the glass preimpregnated fabric has better heat-resistant property than a single alkali-free glass fiber fabric, and moreover, the dielectric property and the mechanical property are more excellent.
Description
[technical field]
The utility model relates to a kind of electrician and uses adhesive plaster, is specifically related to a kind of glass prepreg cloth, belongs to the dielectric material technical field.
[background technology]
The glass fabric of prior art tends to produce distortion in the condition of high temperature, thereby influences its use.Simultaneously, also have a large amount of halide ions in the general glass fabric, vigorously advocate in country under the background of green economy, more and more can not satisfy the needs in market.For solving the problems of the technologies described above, be necessary to provide a kind of heat resistance and the better glass prepreg cloth of mechanical performance.
[utility model content]
For addressing the above problem, the glass prepreg cloth that provides a kind of heat resistance good is provided the purpose of this utility model.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of glass prepreg cloth, comprise the alkali-free glass fiber cloth layer, and evenly be coated with the heat resistant epoxide resin layer in the one side of described alkali-free glass fiber cloth layer.
Glass prepreg cloth of the present utility model further is set to: described heat resistant epoxide resin layer is specially novolac epoxy resin.
Glass prepreg cloth of the present utility model also can be set to: the thickness of described glass prepreg cloth is 0.15～0.25mm.
Compared with prior art, the utlity model has following beneficial effect:
1,, make the more single alkali-free glass fiber cloth heat resistance of this glass prepreg cloth better by a heat-resisting heat resistant epoxide resin layer is set;
2, dielectric and mechanical performance are good, can make coil have good electric, mechanical strength and humidity resistance, are particularly useful for the layer insulation of dry-type transformer coil.
[description of drawings]
Fig. 1 is the cutaway view of glass prepreg cloth of the present utility model.
[specific embodiment]
See also shown in Figure 1ly, the utility model is a kind of glass prepreg cloth, comprises alkali-free glass fiber cloth layer 1, evenly is coated with heat resistant epoxide resin layer 2 in the one side of described alkali-free glass fiber cloth layer 1.In the present embodiment, heat resistant epoxide resin layer 2 is specially novolac epoxy resin.The thickness of described glass prepreg cloth is 0.15～0.25mm.
The technical indicator of glass prepreg cloth of the present utility model is as follows:
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (3)
