Problems solved by technology

Although this adhesive tape can meet the requirements for dimensional accuracy and edge smoothness (fracture smoothness), it cannot be used in rolls because it is in sheet form, which brings inconvenience to the manufacture, application, and transportation of the adhesive tape.
In addition, the access to this sheet of adhesive tape is not very convenient

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with preferred embodiments, and it should be understood that these preferred embodiments are only used to explain the present invention, and do not play a limiting role.

[0043] An embodiment of the present invention is as Figure 2 to Figure 4 shown. figure 2 is a schematic view of one embodiment of an adhesive tape in roll form according to the present invention. image 3 It is the automatic fracture place when the adhesive tape of this embodiment is stretched. Figure 4 It is a schematic diagram after the adhesive tape of this embodiment is automatically broken when stretched and taken. Such as Figure 2 to Figure 4 As shown, the tape is broken along its width at every custom interval along its length. image 3 and Figure 4 The arrows in the arrows respectively show the automatic breaking point of the adhesive tape during stretching and the automatic breaking point after stretching. As sho...

Abstract

The present invention provides a breakable adhesive tape, characterized in that the adhesive tape breaks in the length direction for each customization distance along its width direction. The adhesive tape has advantages that the adhesive tape automatically breaks without using cutter or other cutting tool, when achieving customization length, the usage is very simple, and the fracture of the adhesive tape after broken is leveling, and the size is very accurate. In addition, the distance between automatic fractures is set according to customer requirement, that is the customization distance. Preferably, the adhesive tape has a easier tearing mean, partial and completely having no adhesive near the fracture part broken along the width direction. Thus, the usage of the adhesive tape is convenient and saving on one hand, the further peeling of the release paper and the plastic layer is more convenient and saving labour in the application of the two sides tape, and having no phenomenon ofcolloid residual and colloid fold. The invention also provides a preparing method of the adhesive tape.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an adhesive tape which can be automatically disconnected during use. The invention also relates to a preparation method of the adhesive tape. Background technique [0002] Adhesive tape has been widely used in various fields, such as packaging, stationery, machinery manufacturing, electronic and electrical manufacturing and other industries. In recent years, with the development of the electronic and electrical manufacturing industry, the requirements for tapes have become higher and higher, especially in the process of assembling the inner frame of the liquid crystal display and assembling the internal parts of the mobile phone, etc., the tape is required to have a precise specific length and width. And the edge of the tape must be cut flat. [0003] The most common way is to measure one by one according to the required length and cut it with a knife during the process of using the tape. T...
