Abstract

The invention relates to the technical field of masterbatches, in particular to a transparent flame-retardant masterbatch, a transparent flame-retardant PET film and a preparation method. The transparent flame-retardant masterbatch comprises optical polyester resin, flame-retardant microspheres, a synergistic flame retardant and a dispersant; the flame-retardant microspheres are of a core-shell structure, wherein the core is nano-red phosphorus, and the shell is microcrystalline cellulose; the synergistic flame retardant is a metal hydroxide. By utilizing the microcrystalline cellulose servingas a carbon source to coat red phosphorus serving as an acid source, the compatibility of red phosphorus and an organic polymer can be well improved, and thus the flame-retardant microspheres can besufficiently dispersed in the optical polyester resin; the microcrystalline cellulose has a porous property and can easily form an expandable carbon layer as a carbon source, and the effective range of isolating flame retardance is widened; in addition, by adopting the highly transparent optical polyester resin, the transparency of the masterbatch can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of master batches, in particular to a transparent flame-retardant master batch, a PET film and a preparation method. Background technique [0002] Because of its dimensional stability and high transparency, PET polyester film is widely used in many fields and has a large market. In order to increase the added value of products, many companies are also developing and producing some special PET films, such as colored PET polyester film, matte PET polyester film, twisted PET polyester film, high transparent PET polyester film, antistatic PET Special films such as polyester film. These special films have higher added value than ordinary polyester films, and also have a large market. [0003] Flame retardant PET film is also a kind of special film. At present, the main means of preparing flame-retardant PET film is blending modification. The flame-retardant function is realized by adding a flame retardant to t...
