Abstract

The invention discloses a fluorescent protective film and a preparation method thereof and belongs to the field of packaging industry. The fluorescent protective film comprises a base material layer and a functional coating, wherein the base material layer is made of PE (Poly Ethylene) and has a thickness of 30-60 microns; the functional coating has a thickness of 15-25 microns and comprises the following components in parts by mass: 50-70 parts of acrylic resin, 6-12 parts of polyacrylate, 3-7 parts of nano-titanium dioxide, 4-8 parts of dicumyl peroxide, 0.5-2 parts of aluminate fluorescent powder and 15-25 parts of deionized water. The fluorescent protective film disclosed by the invention is stable in viscous force, good in attachment property, good in re-peeling property and good in fluorescence property, and not only is the aesthetic property of the fluorescent protective film improved, but also a certain identification effect is achieved; therefore, the fluorescent protective film is a good composite functional protective film.

Description

technical field [0001] The invention belongs to the technical field of packaging industry, and particularly relates to a fluorescent protective film and a protection method thereof. The fluorescent protective film can be used for the protection of household appliances. Background technique [0002] The protective film, functionally speaking, is to place a film on the physical objects we want to protect, so as to achieve the purpose of protecting the physical objects. Protective film can be divided into digital product protective film, car protective film, household protective film and food preservation protective film according to the protection purpose. [0003] Among them, the household protective film is mainly used in the home environment to protect the electrical appliances or other items required for the home, and the protective film for protecting electrical appliances is more common. [0004] The protective film used to protect household appliances generally has ant...
