Abstract
The invention discloses a refractory gold mica tape for electric wires and cables, and relates to the technical field of production of auxiliary materials for electric wires and cables, in particular to the technical field of production of mica tapes. The mica tape comprises a glass fiber cloth layer, a mica paper layer and a polyester film layer; the glass fiber cloth layer is stuck to one side of the mica paper layer through a silica gel adhesive layer; and the polyester film layer is stuck to the other side of the mica paper layer through silica gel adhesive. By covering the polyester film layer on the surface of the mica paper layer, the moisture resistance of the mica tape can be improved, and the mica tape has the advantages of high tensile strength, high elastic coefficient, high compressive strength, high refractory performance, good flatness, layering prevention, acid and alkali resistance, corona resistance and the like. The mica tape is difficult to crack due to high impact energy absorption.
Description
Technical field
The present invention relates to the production technical field of electric wire auxiliary material production technical field, particularly mica tape.
Background technology
Mica tape is one of electric wire auxiliary material; High performance mica insulation goods have good resistance to elevated temperatures and flame resistance can; The mica tape normality has good flexibility, is applicable to main refractory insulating layer in the various fire-resistant wire and cables, uses the wrapped cable of phlogopite band; Cable flame resistant temperature can guarantee normal operation circuit in 2 hours up to more than 850 ℃ the time.But alkali glass cloth stretching intensity is low in existing, and coefficient of elasticity is poor, and compression strength is low, and poor flatness, also is prone to phenomenons such as cracking layering.
Summary of the invention
The object of the invention is to propose the electric wire of a kind of intensity height, good planeness, not easy to crack, resistance to acids and bases, anti-corona with fire-resistant phlogopite band.
The present invention includes glass fiber layer of cloth, mica paper layer, laminated polyester film, the glass fiber layer of cloth is bonded in a side of mica paper layer through the silica gel adhesive layer, and laminated polyester film is through the opposite side of silica gel adhesive bond in mica paper layer.
The present invention can increase the moisture resistance of mica tape at the mylar tape of mica paper layer surface coverage, has the hot strength height, coefficient of elasticity is high, compression strength is big, fire resistance is high, good planeness and be difficult for advantages such as layering, resistance to acids and bases, anti-corona.Absorption impact energy of the present invention is big, so be not prone to the phenomenon of cracking.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1; The present invention is provided with glass fiber layer of cloth 1, mica paper layer 2, laminated polyester film 3; Glass fiber layer of cloth 1 is bonded in a side of mica paper layer 2 through silica gel adhesive layer 4, and laminated polyester film 3 is bonded in the opposite side of mica paper layer 2 through silica gel binding agent 5.
