Problems solved by technology

However, it should be pointed out that the tempered glass film in the existing mobile phone screen protection film has the technical problem that it cannot completely absorb the screen; although the TPU soft film can achieve full screen coverage, it is not convenient to fit on the display screen due to its material defects.

Embodiment 1

[0037]This embodiment provides a soft protective film attached to the screen, such as figure 1 and figure 2 As shown, it includes silicone protective film layer 1, TPU soft film 2, release film A3, AB glue 4 and release film B5 arranged in sequence from top to bottom, and the front of the TPU soft film 2 is attached to the printing layer ; The non-release surface of the release film A3 is attached to the OCA surface of the AB glue 4.

[0038] The tpu material is the abbreviation of Thermoplastic Urethane, and the Chinese name is thermoplastic polyurethane elastomer. TPU is a polymer material formed by co-reacting diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular polyols (chain extenders). TPU has excellent characteristics of high tension, high tensile strength, toughness and aging resistance, and is a mature environmental protection material. At present, TPU has been widely used in ...

Embodiment 2

[0041] This embodiment is a further improvement made on the basis of Embodiment 1. The specific differences between this embodiment and Embodiment 1 are:

[0042] It should be further explained in this embodiment that the silicone protective film layer 1 is a printing layer printed with marks. Printing marks on the silicone protective film layer 1 can indicate the mobile phone model, etc., which is convenient for quickly identifying the mobile phone model used for the software protective film, which is easy to distinguish, avoids mistakes, and is more practical.

Embodiment 3

[0044] This embodiment is a further improvement made on the basis of Embodiment 1 or Embodiment 2. The specific differences between this embodiment and Embodiment 1 or Embodiment 2 are:

[0045] What needs to be further explained in this embodiment is that the release film A3 is cut with a knife line. The position of the knife line is about the quarter line and three-quarter line of the release film A3. The knife line is convenient to tear off the release film A3 separately when sticking the film, and stick the TPU soft film 2 to the mobile phone little by little. , making filming easier and positioning more accurate.

Abstract

The invention belongs to the technical field of protective films, and discloses a soft protective film attached to screen a screen, and a manufacturing method thereof. The soft protective film comprises a silicone protective film layer, a TPU soft film, a release film A, an AB glue and a release film B which are sequentially arranged from top to bottom. The manufacturing method comprises the following steps: attaching the non-release surface of the release film A to the OCA surface of the AB glue to obtain a semi-finished product A; cutting the semi-finished product A to form small rolls, andperforming a reverse die-cutting knife line process to cut knife lines on the semi-finished product A to obtain a semi-finished product B; attaching the silicone protective film layer to the front surface of the TPU soft film to obtain a semi-finished product C; cutting the semi-finished product C to form small rolls in order to obtain a semi-finished product D; attaching the release surface of the release film A to the reverse surface of the TPU soft film in order to obtain a semi-finished product E; performing positive die-cutting on the semi-finished product E to obtain a semi-finished product F; and performing UV printing on the silicone protective film layer to obtain the finished product. The soft protective film has the advantages of accuracy in positioning, taking away dusts, avoiding of knife marks and bubbles, and easiness in attachment.

Description

technical field [0001] The invention belongs to the technical field of protective films, and in particular relates to a soft protective film for bonding a screen and a manufacturing method thereof. Background technique [0002] The touch industry includes the touch screen industry, touch module industry, and the rapidly rising fingerprint recognition industry in recent years. All kinds of products are the result of further processing based on touch screen production. The touch screen originated in the United States in the 1960s and was developed by the US military for military use. After more than 50 years of development, touch screens have been widely used now, but they really entered a mature period after 2000. In 2007, the first generation of iPhone opened the prelude to the full touch era of smart phones. In 2010, with the explosive growth of smart phones and the emergence of tablet computers, the core position of touch operations, especially capacitive touch operation...
