Problems solved by technology

Liquid crystal display needs to use reflective film. The general preparation method of existing reflective film is to form white polyester film with microbubbles through biaxial stretching process, and this kind of reflective film is all flammable materials. If it is not treated, the The use of similar reflective films will be limited in some fields that require flame retardant performance

Abstract

A reflecting film with the flame retardant effect comprises a substrate and further comprises a flame retardant coating covering the surface of the substrate. The mode that the flame retardant coating is compounded to the substrate is that firstly, flame retardant coating liquid is prepared, then the surface of the substrate is coated with the flame retardant coating liquid, and the flame retardant coating is formed after the flame retardant coating liquid is dried and cured. The flame retardant coating liquid comprises mixed liquid of ethyl acetate and butyl acetate, a mixture of ammonium polyphosphate, pentaerythritol and melamine, glass beads, CaCO3 particles, Al(OH)3 particles, rutile type TiO2 particles and melamino-formaldehyde resin, wherein the mixed liquid serves as a solvent, the mixture serves as fire retardant and the melamino-formaldehyde resin serves as a curing agent. According to the technical scheme, the reflecting film has the flame retardant property and the reflective index and other properties are not reduced.

Description

technical field [0001] The invention relates to a reflective film. Background technique [0002] Liquid crystal display is the most common display technology today, widely used in TVs, computer monitors, notebook computers, mobile phones, digital cameras, handheld computers, GPS navigators, etc. Liquid crystal display needs to use reflective film. The general preparation method of existing reflective film is to form white polyester film with microbubbles through biaxial stretching process, and this kind of reflective film is all flammable materials. If it is not treated, the The use of quasi-reflective films will be limited in some fields that require flame retardant properties. How to improve the reflectivity while improving the flame retardancy is an important topic in the field of liquid crystal display. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing reflective film, the present invention provides a reflective ...
