Problems solved by technology

However, increasing the dielectric constant of the material is often accompanied by an increase in the dielectric loss, which will not only reduce the transmission power of the line, but also cause the tape to heat up easily under the action of high voltage for a long time, and the bonding performance will deteriorate, which will affect the safe operation of the circuit.

Abstract

The invention provides an insulating rubber tape and a preparation method thereof. The insulating rubber tape comprises a substrate, a first dielectric layer and a second dielectric layer which are stacked sequentially, wherein the first dielectric layer has a negative dielectric constant, the second dielectric layer has a positive dielectric constant, and the absolute value of the dielectric constant of the first dielectric layer is larger than the dielectric constant of the second dielectric layer. The preparation method of the insulating rubber tape comprises the following steps: firstly, components of the first dielectric layer are melted, mixed and calendered on the substrate for semi-curing, then components of the second dielectric layer are melted, mixed and calendered on the firstdielectric layer, and the insulating rubber tape is obtained. The insulating rubber tape has higher dielectric constant, penetration resistance strength and volume resistivity and lower dielectric loss and is particularly applicable to protection of high-voltage alternating-current circuits.

Description

technical field [0001] The invention belongs to the technical field of insulating materials, and in particular relates to an insulating tape and a preparation method thereof. Background technique [0002] Insulating tape is a kind of tape specially used to prevent leakage and play an insulating role. It is suitable for wire connection and electrical insulation protection. It is an indispensable product for industry and household use. It can be used to tightly wrap cable terminals and intermediate joints. , forming a certain characteristic impedance at the end of the cable shield, which plays the role of electrical stress control and sealing bonding, and is used for interlayer insulation and bundling of transformers and transmission lines, fixing of components and connection of damaged lines. [0003] In the context of China's rapid economic development, the contradiction between the people's increasing material needs and environmental resources has become more intensified. D...
