Plastic masterbatch and manufacturing method thereof

Abstract

The invention discloses a plastic masterbatch and a manufacturing method thereof. The plastic masterbatch is used for molding and processing light diffusion and absorption and blue-ray obstructing plastic products, and is mainly composed of plastic powder, light diffusion powder and anti blue-ray powder, the plastic powder is a thermoplastic polymer, the light diffusion powder is silicone resin with methyl as a side chain, the anti blue-ray powder is yellow color powder, the plastic powder as a main raw material is evenly mixed with the light diffusion powder and the anti blue-ray powder for heating and melting into a semi-solid state or liquid melt, and after cooling and drying curing, the plastic masterbatch manufacturing can be completed by applying granulation processing technology to the melt; the plastic masterbatch prepared by mixing of the light diffusion powder and the anti blue-ray powder can be further processed and molded into the plastic products with the uniform light diffusion and absorption and blue-ray obstructing functions, a product in the prior art must be plated with an anti blue-ray film for improving the existing technology, and the production process is complicated.

Description

technical field [0001] The invention relates to a plastic masterbatch and a manufacturing method thereof, in particular to a plastic masterbatch capable of uniformly diffusing light and absorbing and blocking blue light and a manufacturing method thereof. 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 light (Ultraviolet, UV), also known as ultraviolet light, can be divided into near ultraviolet light (Near UV or UVC), mid-ultraviolet (Mid UV or UVB) and far-ultraviolet (Far UV or UVA), among which, the wavelength range of near-ultraviolet is about 190-280nm, most of which will be absorbed by the atmosphere and the ozone layer, while the mid-ultraviolet (wavelength The range is about 280-315nm) and far ultraviolet light (the wavelength range is about 315-380nm), which can damage human skin, ...

Problems solved by technology

[0003] The wavelength range of visible light in the electromagnetic spectrum is about 380nm~700nm, which is the part of the electromagnetic spectrum that can be perceived by the human eye; among them, blue light belongs to visible light with strong energy, and the wavelength range of blue light in the electromagnetic spectrum is about Between 390nm and 500nm, too strong blue light will penetrate the cornea and crystalline lens of the human eye, and directly enter the macula to cause damage to the photoreceptor cells in the macula. In addition, when blue light irradiates the retina, free radicals will be generated, and free radicals will cause retinal pigment epithelial damage. Cell death leads to the lack of nutrients for light-sensitive cells. Furthermore, due to the shorter wavelength of blue light, the scattering is more serious than other visible light. When the eyes are focused for a long time, they are prone to fatigue and form pseudomyopia.
