Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a double-sided highly flame-retardant and anti-aging adhesive tape. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used. Adhesives can stick to things because bonds are formed between their own molecules and the molecules of the objects to be connected. This bond can firmly bond the molecules together.

[0003] After searching, the patent with application number CN201720284360.8 discloses a wear-resistant and anti-aging Teflon tape, which includes a glass fiber base cloth, a wear-resistant silicone rubber layer covered on the first side of the glass fiber base cloth, a polytetrafluoroethylene coating coated on the outer surface of the wear-resistant silicone rubber layer, a non-woven fabric layer covered on the second side of the glass fiber base cloth, and a viscose layer covered on the outer surface of the non-woven fabric layer. The tape is combined in a multi-layer manner to form multiple functions. When the tape is used, there is no buffering or pressing protection structure after it is pressed or bent, so that after the tape is adhered, the viscose at the bend is easily lifted and detached, resulting in the problem of loose adhesion of the tape. For this reason, a double-sided high flame retardant and anti-aging tape is proposed. Utility Model Content
