Problems solved by technology

The screen protective film products currently on the market can only provide basic protective functions such as scratch resistance, and the function is single. However, the common impact-resistant elastic protective film has shortcomings such as poor impact resistance and too thick size. Damage does not provide protection, and cannot effectively reduce the probability of damage to mobile phone display components

Abstract

The invention relates to the technical field of optical protection films and particularly relates to a vibration-absorption protection film and a preparation method thereof. The vibration-absorption protection film comprises a buffering layer, a protection layer and a stripping layer, wherein the buffering layer comprises 2-5 layers of transparent thin films, a sticking layer arranged between each two layers of the transparent thin films, a UV coating arranged on the upper surface of the transparent thin film on the topmost layer, and a low-viscidity adhesive layer arranged on the lower surface of the transparent thin film on the bottommost layer; the protection layer is located on the upper surface of the UV coating; the stripping layer is located on the lower surface of the low-viscidity adhesive layer; the adhesive force of the sticking layer arranged between each two layers of the transparent thin films is 0.03kg / 25mm-0.08kg / 25mm, and the adhesive force of the low-viscidity adhesive layer is 0.01kg / 25mm-0.025kg / 25mm; and the vibration-absorption protection film can be used for effectively reducing the possibility that a cell phone display screen assembly is damaged, cell phone surface glass can be effectively prevented from being cracked in instant impacts by a testing ball / 100cm height impact test, and the vibration-absorption performance is good.

Description

technical field [0001] The invention relates to the technical field of optical protective films, in particular to an anti-vibration protective film and a preparation method thereof. Background technique [0002] Nowadays, smartphones and tablet computers have become one of the necessities of life for most people. As large screens gradually become the mainstream, the maintenance of the screen is becoming more and more difficult. The glass of the screen is broken or crushed from time to time. . The screen protective film products currently on the market can only provide basic protective functions such as scratch resistance, and the function is single. However, the common impact-resistant elastic protective film has shortcomings such as poor impact resistance and excessive thickness. Damage does not play a protective role, and cannot effectively reduce the probability of damage to mobile phone display components. Therefore, there is an urgent need in the market for a screen p...
