Embodiment Construction

[0014] see figure 1 The adhesive tape 10 according to the embodiment of the present invention includes a base 11 , an adhesive layer 13 formed on the base 11 and a plurality of colloidal particles 15 dispersed on the surface of the adhesive layer 13 , the adhesive force of the adhesive layer 13 is greater than that of the colloidal particles 15 . The substrate 11 can be a plastic film. It can be understood that the substrate 11 is not limited to plastic film, and may also be other substrates used for tapes, such as kraft paper, textured paper, and the like. In this embodiment, the adhesive force of the adhesive layer 13 is greater than 10 Newtons per inch (N / in); the adhesive force of the rubber particles 15 is approximately in the range of 1-10 N / in.

[0015] Please also refer to Figure 2 to Figure 4 , the apparatus 200 for manufacturing the adhesive tape 10 according to the embodiment of the present invention includes a conveying roller 20 , a coating roller 40 , a first ...

Abstract

A manufacturing method of an adhesive tape comprises the following steps: an apparatus is provided, which comprises a coating roller, a spraying device and a plurality of transfer rollers, wherein the coating roller is coated with a first adhesive, the spraying device is filled with a second adhesive, the adhesive force of the first adhesive is larger than that of the second adhesive, and both the coating roller and the spraying device are disposed between the plurality of transfer rollers; a substrate is provided, which is disposed on the plurality of transfer rollers and is transferred to the coating roller by the rotation of the plurality of transfer rollers; the coating roller rolls and presses the substrate to allow the first adhesive to be pressed on and adhered to the substrate to form an adhesive layer; the spraying device sprays the second adhesive to the surface of the adhesive layer to form a plurality of adhesive particles dispersed on the surface of the adhesive layer, so as to obtain an adhesive tape. The adhesive tape manufactured by the method is easy to peel off, and has good adhesion performance.

Description

technical field [0001] The invention relates to a method for manufacturing an adhesive tape and equipment used therefor. Background technique [0002] Glue is currently used in consumer electronics to bond two workpieces together. On the one hand, the viscose must have good cohesiveness to firmly bond the parts; It needs to have better tear-off property. The current manufacturing method of the adhesive tape includes the following steps: rolling the coating roller against the surface of the substrate to form an adhesive layer on the surface of the substrate; then drying the substrate to obtain the adhesive tape. However, it is difficult to balance the adhesiveness and easy-tearability of the adhesive tape manufactured by the above method. Contents of the invention [0003] In view of the above, it is necessary to provide a method for manufacturing an adhesive tape that is easier to tear off, and it is also necessary to provide a device for the above-mentioned adhesive ta...
