Problems solved by technology

However, PVC produces harmful gases. In order to impart fire resistance, a large amount of flame retardant needs to be added, resulting in uneven tape and affecting the bonding ability. In this case, consider using softer olefin resin as the base material of the tape. However, poly Olefin materials are inherently combustible, and in order to impart flame retardancy, inorganic m...

Abstract

The invention discloses a flame-retardant polyester adhesive tape base material. The adhesive tape base material comprises a polyester chip, a dispersing agent, a heat stabilizer, magnesium hydroxide, nano-zinc oxide and a functional auxiliary; the functional auxiliary is of a microcapsule structure, the particle size range of the microcapsule structure is 10-100 microns, the thickness ratio of a wall material to a core layer is 1:18-1:22, the core layer is composite powder, and the wall material is a polyester film; the composite powder is a mixture which contains titanium dioxide and silicon dioxide, and the particle size range is 50-100 nm. The adhesive tape base material has the advantages of good heat resistance and mechanical strength, flame retardation, good toughness, good transparency and the like.
