Abstract

The invention provides an adhesive tape device. The device comprises a shell body, a baseplate, super-aligned carbon nanotube arrays and at least two adhesive tape pulling elements. The shell body isprovided with an opening; the baseplate is positioned in the shell body; the super-aligned carbon nanotube arrays are arranged on the baseplate, positioned in the shell body, and used for continuouslypulling adhesive tape out of the super-aligned carbon nanotube arrays; the adhesive tape pulling elements are arranged on the baseplate, and the adhesive tape pulling elements and the super-aligned carbon nanotube arrays are disposed at intervals; the adhesive tape pulling elements are used for fixing the adhesive tape pulled from the super-aligned carbon nanotube arrays, and the adhesive tape inthe shell body is pulled out from an opening of the shell body through at least one of the adhesive tape pulling elements.

Description

technical field [0001] The invention relates to an adhesive tape device, in particular to a carbon nanotube adhesive tape device. Background technique [0002] In daily life and industrial production, double-sided tape is commonly used to bond objects. However, the existing double-sided adhesive tapes generally have a narrow temperature range, and the viscosity is significantly reduced or even lost at high temperature (eg, higher than 70° C.) and low temperature (eg, lower than 0° C.). SUMMARY OF THE INVENTION [0003] In view of this, it is indeed necessary to provide an adhesive tape device, the double-sided adhesive tape provided by the adhesive tape device can be used in a wide temperature range. [0004] An adhesive tape device, comprising: a casing with an opening; a substrate located inside the casing; a super-aligned carbon nanotube array, the super-aligned carbon nanotube array being arranged On the substrate and inside the casing, the super-aligned carbon nanot...
