Abstract

The invention relates to the technical field of functional polymer materials, and provides a light-diffusion PP material and a preparation method thereof. The problem that since a conventional PP material has poor thermal stability and weak impact resistance, the utilization rate of the conventional PP material is low in the lamp industry is solved. The light-diffusion PP material comprises the following components: in parts by weight, 90-98 parts of polypropylene, 0.2-1 part of a light-diffusing agent, 0.05-3 parts of a flame retardant, 0.05-1 part of an antioxidant, 0.05-1 part of a lubricant and 0.5-5 parts of an anti-UV agent. The light-responsive gel factor compounded light-diffusing agent and the green environment-friendly flame retardant are utilized, so that evener distribution, better fluidity, higher impact resistance and higher light sensing regulation ability of the light-diffusion PP material system are achieved; and the modified light-diffusion PP material has better thermal stability, the softening temperature can reach 105 DEG C, the modified light-diffusion PP material has better anti-aging performance, and the yellowing performance can still be ensured under irradiation of high-intensity ultraviolet.

Description

technical field [0001] The invention relates to the technical field of functional polymer materials, in particular to a light-diffusing PP material and a preparation method thereof. Background technique [0002] LED is the abbreviation of "Light Emitting Diode", which is translated as "light emitting diode" in Chinese. It is a new type of semiconductor solid light emitting device. Light. LEDs made of different materials emit light of different wavelengths, resulting in different colors. LED has the characteristics of low energy consumption, small size, long life, no pollution, fast response, low driving voltage, strong shock resistance, high color purity, etc., and is known as a new generation of lighting source and green light source. [0003] When the light passes through the diffusion layer of the plastic substrate and encounters a medium (diffusion particles) with a different refractive index, multi-angle and multi-directional refraction, reflection and scattering will...
