Problems solved by technology

[0002] At present, the domestic sealing and insulating materials used in power and communication systems have poor water, alkali, acid and electrical properties, poor applicability, and poor self-adhesive workmanship. At present, most of them are imported from 3M and other companies, and the price is relatively high.
[0003] At present, our country already has the technology and ability to manufacture various types of self-adhesive tapes. In order to make the products can be used in more fields, the transparency of the sheet is extremely high. Therefore, during production and molding, the surfaces are often pasted together and are not easy to separate. , or often form scratches, friction and other quality problems when separating, usually customers will use coating technology, but mottled will be formed on the surface, and there are environmental protection and hygiene problems in the use of food, medical and other fields, which restricts the widespread use of PET tape application

Abstract

The invention discloses a self-adhesive PET (polyethylene glycol terephthalate) adhesive tape, which comprises the following components in parts by mass: 100 parts of basic rubber, 30 to 50 parts of micro-powder silicon, 20 to 40 parts of tackified rubber, 50 to 200 parts of micro-powder silicon dioxide, 10 to 20 parts of reinforced resin, 0.5 to 1.5 parts of vulcanizing agents, 4 to 6 parts of accelerants, and 3 to 50 parts of black carbon. According to the self-adhesive PET adhesive tape, by adding the composite micro-powder particles of the silicon dioxide and the silicon in a functional layer of the PET adhesive tape, the microscopic roughness of the surface of the adhesive tape is increased, so that a little air can be accommodated between the adhesive tapes during a winding-up period, so as to prevent the adhesive tape from adhesion and to realize the effect of easy separation; moreover, the grades of the particle sizes of the particles of the silicon dioxide and the silicon, which are added into the self-adhesive PET adhesive tape, are different; the amount of the accommodated air is large; the anti-adhesion effect is good; the procedure of the surface coating of the manufactured PET adhesive tape is omitted; the pollution, generated due to the coating, of the adhesive tape is reduced; the environment-friendly quality level and the serviceable range of the adhesive tape are increased.
