Abstract
The utility model discloses glass fiber cloth for electrical insulating plates produced by starch-type yarns, which is formed by weaving starch-type sizing glass fiber yarns used as warp yarns and weft yarns, and each bundle of warp yarns or weft yarns is composed of 400 single filaments with diameters of 9 micrometers. Weight per unit area of the glass fiber cloth can be adjusted from 140 grams per square meter to 220 grams per square meter according to different needs. The glass fiber cloth for electrical insulating plates produced by starch-type yarns changes the mode that glass fiber cloth for traditional electrical insulating plates uses paraffin-type sizing, processing performances of the glass fiber cloth are obviously improved during plate clamping process, de-waxing treatment is avoided, binding property and thorough reaction of the glass fiber cloth and resin are improved, mechanical properties of the insulating plates are increased, and performances of the insulating plates are increased.
Description
Technical field:
The utility model relates to a kind of with starch type yarn production electrical insulating board glass fabric.
Background technology:
The glass fabric that China's production electrical insulating board is used all forms with the glass yarn weaving of paraffin wax type sizing agent; and all form with 200 monofilament; lamination appears in regular meeting when producing insulation board; thereby cause the mechanical property of substrate and electrical property to descend; more since paraffin wax type glass cloth when high-temperature molding; paraffin wax is handled cumbersome; do not handle and to cause the paraffin wax fusing; influence the interlayer bonding force of insulation board; at present all use the glass cloth of 0.14mm to be the master, the performance that improves insulation board is had significant limitation.
Summary of the invention:
The utility model provides a kind of and produces the electrical insulating board glass fabric with the starch type yarn in order to overcome above-mentioned defective, have the wettability and the stitchability that have increased glass fibre, produce electrical insulating board with it, its mechanical property, the advantage that electrical property all improves greatly.
The utility model is achieved through the following technical solutions for achieving the above object:
A kind of with starch type yarn production electrical insulating board glass fabric, doing the braiding of warp thread, weft yarn by starch type sizing agent yarn forms, it is characterized in that, every bundle warp thread, weft yarn are formed by 200～400 monofilament, every single directly 7～9 microns, the unit are of described glass fabric is mainly 140～220g/m
2
Wherein, preferred described every bundle warp thread, weft yarn are formed by 400 monofilament, and every filament diameter is 9 microns, and described glass cloth unit are is at 140g/m
2Adjustable.
Wherein, the starch of using in the starch type sizing agent adopts high straight key starch, helps the abundant infiltration of glass fibre, increases stitchability.
The utility model compared with prior art, its advantage is, described with starch type yarn production electrical insulating board glass fabric, the wettability and the stitchability of glass fibre have not only been increased, produce electrical insulating board with it, its mechanical property, electrical property all improves greatly, and, select high-grade cloth for whole electrical insulating board industry a basis is provided for electrical insulating board provides a kind of novel glass fabric.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of with starch type yarn production electrical insulating board glass fabric, doing 2 braidings of warp thread 1, weft yarn by starch type sizing agent yarn forms, every bundle warp thread 1, weft yarn 2 are formed by 400 monofilament, and every single directly 9 microns, the weight per unit area of described glass fabric is 140g/m
2Wherein, the starch of using in the starch type sizing agent adopts high straight key starch, helps the abundant infiltration of glass fibre, increases stitchability.
