Problems solved by technology

[0003] The existing mica paper products are usually directly stacked on the surface of the unit to be dissipated when used as an insulating material, which is not convenient to use, and has poor adhesion performance and is prone to displacement. During long-term use, It is easy to cause its thermal conductivity, mechanical properties and electrical insulation properties to be unsatisfactory due to the problem of its surface bonding performance; at the same time, due to this stacking form, its interlayer structure is prone to displacement wear, and the traditional mica paper is also poor in wear resistance, and it is prone to wear during use, thereby accelerating the aging phenomenon during long-term use and affecting the thermal conductivity, mechanical properties and electrical insulation properties of the mica paper tape

Abstract

The invention discloses a high-wear-resistance mica paper adhesive tape and a preparation method thereof. A mica paper base tape of the mica paper adhesive tape prepared by the preparation method is adouble-layer mica paper tape; wherein a nickel-plated graphene layer is formed between the two layers of mica paper tapes; the inner side surface of the mica paper base band is a sticking surface; aninsulating rubber layer doped with inorganic phase-change material particles is formed on the surface; a release film is formed through the insulating rubber layer, a plurality of reinforcing bands are formed on the outer side face of the mica paper base tape, and surface sealing and reinforcing are conducted on the outer surfaces of the reinforcing bands and the mica paper base tape through resin reinforcing layers with aramid fibers, silica powder and conductive filler. The mica paper adhesive tape prepared by the preparation method disclosed by the invention is relatively good in fitting degree and adhesion property, has excellent characteristics of insulation, high temperature resistance and the like of mica paper, and has relatively high mechanical strength, toughness and surface wear resistance.

Description

Technical field [0001] The invention relates to the field of insulating mica products, in particular to a high wear-resistant mica paper tape with better physical properties and a preparation method thereof. Background technique [0002] Mica paper products are currently one of the most widely used mica applications. The mica flake raw material is broken into fine mica flakes by thermochemical or hydraulic peeling, and then paper-based insulation material prepared by modern wet papermaking. It is widely used as an insulating material in cables and large electromechanical equipment. It has high electrical strength, low dielectric loss, high surface resistance and high volume resistance. It also has high insulation, anti-corona, acid and alkali resistance, and radiation resistance. , Chemical stability, elasticity, high peelability, shear resistance and tensile strength and other excellent physical and chemical properties. [0003] The existing mica paper products are usually direct...
