Abstract

The invention relates to a flame-retardant masterbatch for a reflective film. The masterbatch comprises the following components in parts by mass: 0-100 parts of carrier, 20-60 parts of toner, 5-10 parts of a flame retardant, 10-20 parts of a flame-retardant assistant, 1 part of a heat stabilizer and 2-4 parts of a dispersant, wherein the toner is acid-resistant organic or inorganic toner; the flame retardant is a brominated flame retardant; the flame-retardant assistant is a nano inorganic flame retardant; the part ratio of the flame retardant to the flame-retardant assistant is 1:2; the heat stabilizer is polyphosphate; the dispersant is an organic or inorganic dispersant; and a high-efficiency fluorescent brightener can also be added to the masterbatch. The masterbatch has the characteristic that the masterbatch can reach a requirement of the masterbatch for the reflective film by setting the components.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a flame-retardant color masterbatch for a reflective film. Background technique [0002] The reflective film can generally be divided into two categories, one is the metal reflective film, and the other is the all-dielectric reflective film. The all-dielectric reflective film is based on multi-beam interference. A layer of thin film with a higher refractive index than the base material can increase the reflectivity of the optical surface. The simplest multi-layer reflection is formed by alternate evaporation of two materials with high and low refractive index. The optical thickness of each layer of film It is a quarter of a certain wavelength. Under this condition, the reflected light vectors on the superimposed surfaces have the same vibration direction, and the combined amplitude increases with the increase of the number of film layers. [0003] The color masterbatch is an aggregate made...
