specific Embodiment 1

[0016] Take 90 parts of polycarbonate powder, 5 parts of iron oxide nanoparticles with a particle size of 10 nm, 3 parts of maleic anhydride grafted POE, 1 part of heat stabilizer and 1 part of antioxidant.

[0017] A preparation method for an anti-blue light polycarbonate film, comprising the following process steps:

[0018] A) Mechanical premixing: Take 85 parts of polycarbonate powder, 10 parts of iron oxide nanoparticles with a particle size of 10 nanometers, 3 parts of maleic anhydride grafted POE, 1 part of heat stabilizer and 1 part of antioxidant. , and put it into a high-speed mixer to fully and evenly mix and stir; the mixing method and time directly affect the quality of the particles and the surface quality of the film and film produced by the particles. The mixing method adopts low mixing-high mixing-low mixing alternately, so that the base material, various powders and additives can be mixed and dispersed evenly and effectively.

[0019] B) Melt mixing: Put the...

Abstract

The invention discloses an anti-blue light polycarbonate film and a preparation method thereof. The anti-blue light polycarbonate film comprises the following components in parts by weight: 75-90 parts of polycarbonate powder, 5-15 parts of anti-blue light nano particles, 2-5 parts of a compatilizer and 2-5 parts of other auxiliaries. The preparation method of the anti-blue light polycarbonate film comprises the following process steps: A) mechanical premixing; B) melt mixing; C) cooling and pelletizing; D) extrusion molding, so that the preparation of a product is finally realized. The anti-blue light polycarbonate film disclosed by the invention is simple in process flow, high in production efficiency, low in cost, good in absorption property of blue light and ultraviolet light and high in light transmittance and can better play roles in protecting eyes and avoiding the harm of the high-energy shortwave blue light when being used on an electronic product.

Description

technical field [0001] The invention relates to a polycarbonate film with simple production process, high efficiency and good performance in absorbing blue light and ultraviolet light and a preparation method thereof. Background technique [0002] With the application and popularization of electronic products, people spend more and more time using electronic products. However, the visible light emitted by the screens of 3C electronic products such as computers, mobile phones, and televisions is rich in a large amount of irregular high-energy short-wave blue light, which will damage the eyes. Causes a kind of photochemical damage, rapidly accelerates the oxidation process of the macular area of ​​the eye and causes great damage to the eyes, causing symptoms such as dry eyes, eye irritation and sore eyes, so the screen surface of these 3C products is covered with a layer of blue light Protective film is the best means of protection now. However, the existing anti-blue light p...
