Problems solved by technology

These anti-blue light layers can effectively reduce the damage to the eyes caused by the blue light that exists during use. However, the production process is relatively complicated. Moreover, the product after coating or coating will reduce the brightness, resulting in differences in visual brightness.

Abstract

The invention discloses an anti-blue-light screen protection film base film and a functional master batch thereof. The functional master batch can comprise a silicon-containing functional master batch and / or an anti-blue-light functional master batch. The anti-blue-light screen protection film base film is composed of an A layer, a B layer and a C layer which are formed into a whole, the A layer and the C layer are surface layers, the B layer is a core layer, and the B layer is prepared from 80% of PET and 20% of anti-blue-light functional master batch. In addition, the invention further discloses an anti-blue-light screen protection film base film containing the anti-blue-light functional master batch, and a preparation method thereof. According to the screen protection base film with the anti-blue-light function, the damage of blue light to eyes during use can be effectively reduced, the process is simple and reliable, the brightness, the color and the transparency of the base film cannot be reduced, the difference in visual brightness cannot be caused, and the anti-blue-light function can be achieved without secondary processing.

Description

technical field [0001] The invention relates to a screen protective film base film and a manufacturing method thereof, in particular to a screen protective film base film which absorbs and blocks blue light and a preparation method thereof, and also relates to a functional masterbatch for producing the film. Background technique [0002] Light is divided into visible light and invisible light, infrared and ultraviolet light are invisible light, while red, orange, yellow, green, blue, indigo, and purple light are visible light; ultraviolet (Ultraviolet, UV) can be divided into near ultraviolet (Near UV or UVC), medium Ultraviolet rays (Mid UV or UVB) and far ultraviolet rays (Far UV or UVA), among which, the wavelength range of near ultraviolet rays is about 190-280nm, and most of them will be absorbed by the atmosphere and the ozone layer, while the middle ultraviolet rays (the wavelength range is about 280-280nm). 315nm) and far ultraviolet light (wavelength range between 3...
