A kind of processing method of sealing tape

Abstract

The invention provides a kind of adhesive tape that has no right-angled corners at the upper and lower ends, will not cut the user, and has no stickiness on the end surface of the tape roll, which is more convenient to take and use, and has a better user experience. The processing method of box tape. It includes the following main steps: adding acrylic acid, the raw material of the tape, to the emulsification tank for emulsification; then putting it into the reaction pot for heating to make glue; then adding it to the coating machine; installing the plastic film roll on the coating machine, through The machine applies glue to the plastic film to make a master roll; the master roll is cut through the pipe cutting machine; the tape after the successful pipe cutting is slit by a slitting machine to obtain a roll of tape; the tape after slitting Use a grinder to grind the upper and lower inner corners of the paper core of the tape; grind the right-angled corners of the inner corners into a bevel or arc surface; evenly stick the paper core powder left over from the grinding of the right-angled corners to the tape roll of the tape Finished sealing tape is made on the end face.

Description

technical field [0001] The invention relates to a processing method of an adhesive tape, in particular to a processing method of a case-sealing adhesive tape. Background technique [0002] Since Richard Drew invented scotch tape in St. Paul, Minnesota, USA in 1928. Tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, die-cut tapes, and sealing tapes according to their functions. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; in modern times, various polymers are widely used. Take the sealing tape as an example, the sealing tape in the prior art is mainly a single-sided adhesive tape, and its structure is as attached figure 1 As shown in , it includes two parts: tape rol...

AI Technical Summary

Problems solved by technology

This kind of stickiness will cause the following inconveniences during the use of the sealing tape: 1. When the user takes a roll of tape from the stacked tapes, it is often caused by the mutual adhesion between the end faces of the tape rolls, resulting in It is very inconvenient to take out multiple rolls at a time

2. The end surface of the tape roll will stick to your hands, and it is easy to stick to things in contact with it when placed

[0016] To sum up, the sealing tape processed by the processing method of the sealing tape in the prior art has the following two disadvantages: 1. The upper and lower ends of the paper core 02 are right-angled corners, and when it touches the user's hand, When relatively rotating, it is easy to cut the user

2. When the user takes a roll of tape from the stacked tapes, it is inconvenient to use

3. The end surface 03 of the tape roll is easy to distribute. The glue is sticky and sticky during use. At the same time, it is easy to stick to the things in contact with it when it is placed.
