Problems solved by technology

[0011] However, since the base material of the conventional double-sided tape is made of a foam, the thickness of the base material becomes thicker, which causes the problem that the thickness of the double-sided tape becomes thicker.

Abstract

An adhesive tape, according to the present invention, comprises a substrate, and an adhesive layer that is laminated on one or both surfaces of the substrate, wherein the substrate and / or the adhesive layer are made into a nanoweb form in which fiber filaments are collected by means of an electrospinning technique, so that the adhesive tape can have a slim thickness, improved adhesive force, can be accurately adhered to a curved surface, and prevent the adhesive layer from remaining on the surface of a part when separating the adhesive tape from the part.

Description

technical field [0001] The invention relates to an adhesive tape with adhesive layers on both sides or one side, and in more detail, relates to an adhesive tape prepared by an electrospinning method and a preparation method thereof. Background technique [0002] In general, double-sided adhesive tape is widely used for fixing internal parts of various electronic devices such as current terminals and portable electronic devices. [0003] At present, with the trend of ultra-thin, miniaturized and lightweight portable electronic devices, double-sided tapes are being researched and developed in the direction of making the thickness thinner and strengthening the adhesive force. [0004] The double-sided adhesive tape includes: a substrate type, which has a substrate for strengthening in the middle, and an adhesive layer is laminated on both sides of the substrate; and a substrateless type, which has no substrate and is formed of only an adhesive layer. [0005] In the case of th...
