Zusammenfassung: | The invention relates to a single-sided glass cloth-reinforced dry mica tape and a wire rod. The single-sided glass cloth-reinforced dry mica tape is composed of the following components in percentageby mass: on the basis that the mass of an adhesive is 100%, 9 to 13% of organic silicon modified epoxy resin, 0.4 to 2% of silicon dioxide, 22 to 30% of acetone and 59-68% of toluene. The adhesive for the single-sided glass cloth-reinforced dry mica tape has relatively large relative molecular mass, has relatively high viscosity at normal temperature, and is beneficial for adhesion between glasscloth and mica paper; and meanwhile, the adhesive has lower viscosity at high temperature, so the permeation of the adhesive on the mica paper is facilitated, the adhesive area of the mica paper is increased, and the adhesive strength between the glass cloth and the mica paper is thus increased. Besides, the adhesive has good heat resistance and good compatibility with VPI impregnating resin, so the use requirements of win |
