Problems solved by technology

[0004] As the tempered glass film uses glass as the main material, glass is a material with very high hardness and cannot be bent, which leads to the problems of air bubbles and snowflakes in the lamination process of the product

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, an anti-blue light flexible glass explosion-proof film, from top to bottom sequentially includes a first PET layer 1, a first silicone pressure-sensitive silicone layer 2, a polyurethane acrylic coating layer 3, a PC / PMMA substrate 4, and an anti-blue light coating Layer 5, second PET6 layer, second silicone PSA layer 7 and third PET layer 8.

[0026] Wherein, the thicknesses of the first PET layer 1, the second PET6 layer and the third PET layer 8 are respectively 0.025-0.075 mm. The PET layer is used to protect the application layer after coating the silicone pressure sensitive adhesive.

[0027] Wherein, the thickness of the first silicone pressure-sensitive silicone layer 2 is 0.05-0.015mm, so as to protect the polyurethane acrylic coating layer 3 from being scratched before use; the thickness of the second silicone pre...

Abstract

The invention discloses an anti-blue light flexible glass explosion-proof membrane and a preparation process thereof. The present invention makes finished products by using PC / PMMA film, UV-curing paint on it, and pasting acrylic and silica gel on the bottom. UV curable coatings have high hardness and anti-fingerprint performance, which can reach or approach the effect of glass surface; after PC / PMMA film is coated with UV curable coating, it can achieve the effect similar to glass breaking after bending; after PET is coated with acrylic and film Fitting, increasing the thickness and hardness of the product, so that the product has an explosion-proof effect; the PET lower layer coated with silicone pressure-sensitive adhesive can be attached to the surface of the screen. The anti-blue light coating is added in the production process, so that the product can effectively block the blue light of 450-480nm, and prevent the blue light from damaging the eyes when looking at the screen for a long time. The present invention has the function of preventing blue light and can well protect users' eyes.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to an anti-blue light flexible glass explosion-proof film and a preparation process thereof. Background technique [0002] Tempered glass film is a kind of mobile phone screen protection product that is popular among consumers at present. It has beautiful appearance, bare metal touch, high hardness and high light transmittance. This product is composed of two parts, tempered glass and AB glue. AB glue refers to a product that uses PET as the base material, one side is coated with acrylic, and the other side is coated with silicone. Die-cutting manufacturers purchase tempered glass and AB glue separately, and use tempered glass to bond the acrylic layer of AB glue to form a tempered glass film. [0003] The thickness of tempered glass is usually less than 0.4mm, so there are high defective products in the production process; before the AB glue is pasted on the tempered glass,...
