Problems solved by technology

[0003] However, the current insulating tape has defects during use. The tape has a certain waterproof performance but is easily damaged, which reduces the performance of the insulating tape.
Therefore, people usually need to wrap more than two layers of insulating tape to prevent it from wearing and tearing, which increases the amount of insulating tape used; at the same time, winding too many layers of insulating tape tends to reduce the bonding strength between layers and affect the sealing of the insulating tape. performance
The cost performance of the current insulating tape is unreasonable, and the preparation process is uneven, which needs further improvement and standardization

Abstract

The invention discloses a preparation method of a novel insulated rubber tape. The preparation method comprises the following steps of: a) preparing a base band layer; b) thermally treating the base band layer; c) coating an adhering layer; and d) post-treating the tape. The invention discloses the preparation method of the novel insulated rubber tape. The preparation method is reasonable in step arrangement and simple and convenient in preparation process. The base band layer in the tape has unique fiber constitution and structure, so that the prepared tape has more excellent strength, elasticity and insulating performance. Meanwhile, the tape is moderate in thickness, and the sealing and insulating demands can be satisfied by winding the tape by two layers generally, therefore, the practical value of the tape can be effectively enhanced.

Description

technical field [0001] The invention belongs to a preparation method of an adhesive tape, in particular to a preparation method of a novel adhesive tape with high strength and outstanding insulation performance, and belongs to the technical field of adhesive tapes. Background technique [0002] Insulating tape refers specifically to the tape used by electricians to prevent leakage and to play an insulating role, also known as insulating tape. The insulating tape is mainly composed of a base belt layer and a pressure-sensitive adhesive layer. The material of the base belt layer is generally cotton cloth, synthetic fiber fabric and plastic film, etc. The pressure-sensitive adhesive layer is made of rubber and tackifying resin and other compounding agents. It has good viscosity and insulation. Excellent performance. Insulating tape has good insulation and voltage resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, ele...
