Abstract

The invention discloses a scratch-resistant protective film and a preparation method thereof and belongs to the field of packaging industry. The scratch-resistant protective film comprises a substrate layer and a functional coating, wherein the substrate layer is PE which is 30-60 microns in thickness and the functional coating is 15-25 microns in thickness. The functional coating comprises the following components in parts by mass: 50-70 parts of organic silicon resin, 6-12 parts of polyisocyanate, 3-7 parts of nanotitanium oxide, 4-8 parts of a silane coupling agent, 0.5-2 parts of a graphite powder and 15-25 parts of deionized water. The scratch-resistant protective film disclosed by the invention is stable in viscous force and good in adhesiveness and re-peeling property, has a good wear-resistant and scratch-resistant performance, and can be effectively used for preventing household appliances from being physically scratched, so that the service lives of the household appliances are prolonged.

Description

technical field [0001] The invention belongs to the technical field of packaging industry, and in particular relates to an anti-scratch protective film and a protection method thereof. The anti-scratch 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...
