Problems solved by technology

[0002] At present, the processing method of flame retardant film not only leads to the phenomenon of solvent residue in the product, but also causes environmental pollution and endangers human health during the production process. The diluent used cannot be completely eliminated, and it is easy to cause safety hazards, etc. Secondly, the dry composite membrane is a process eliminated by advanced countries due to its high rigidity and non-softness, which limits its scope of use.

Abstract

The invention relates to a flame retardant film, comprising: a PET base material, a flame retardant layer is provided on both sides of the PET base material, and the thickness of the flame retardant layer is 5-20 μm, wherein the flame retardant layer consists of the following weight Raw material composition: 100‑200 parts of polyester chips, 2‑20 parts of zinc oxide, 0.1‑20 parts of decabromodiphenylethane, 0.5‑5 parts of aluminum hydroxide, 0.1‑4 parts of ammonium phosphate, 1 part of polyvinyl alcohol -10 parts, 1-5 parts of 2-carboxyethylphenylphosphinic acid. The flame-retardant film prepared by the multi-layer composite technology of the present invention has high flame retardancy, environmental protection, transparency, and heat resistance. The preparation method of the present invention shortens the production and manufacturing process, avoids environmental pollution, and has low raw material cost and is non-toxic. Environmentally friendly film.

Description

technical field [0001] The invention relates to a flame-retardant film and a preparation method thereof, belonging to the field of polymer materials.
