Problems solved by technology

When molding an aromatic polycarbonate resin such as PC optical materials into a light diffusion plate, in order to achieve a larger screen size, it is necessary to increase the molding temperature in order to obtain sufficient melt fluidity, but due to the thermal aging of the polycarbonate resin used The color tone of the light-diffusing plate is slightly yellow, so it is difficult to obtain a light-diffusing plate with satisfactory performance, and a resin material with excellent light-diffusing performance that can enlarge the screen is required

Abstract

The invention discloses a light-diffusion anti-glare nano polycarbonate (PC) material as well as preparation and application thereof in an LED (light-emitting diode) illumination material and belongs to the technical field of light-diffusion anti-glare nano PC materials. The light-diffusion anti-glare nano PC material comprises the following components in parts by weight: 100 parts of PC, 0.01-0.1 part of hindered phenol type antioxygen, 0.01-0.1 part of phosphite ester type antioxygen, 0.1-2.0 parts of polysiloxane particles serving as a light diffusing agent and 0.1-0.5 part of lubricating agent. The preparation method comprises the following steps of: putting uniformly-mixed raw materials in a feeding hopper of a dual-screw extruding machine, carrying out melt extrusion, cooling, and granulating. Compared with the existing LED light-diffusion material, the prepared light-diffusion anti-glare nano PC material has excellent luminous flux under the condition of same haze. A proper production device is selected, thus polymer degradation is reduced, the stability of the light-diffusion anti-glare nano PC material is improved, and factorized massive production of the light-diffusion anti-glare nano PC material is favorably realized.

Description

technical field [0001] The invention belongs to the technical field of light-diffusion and anti-glare nano-polycarbonate (PC) materials, in particular to a light-diffusion and anti-dazzle nano-PC material and its preparation and application in LED lighting materials. Background technique [0002] According to authoritative statistics, social lighting electricity consumption in countries around the world accounts for about 10% to 20% of the country's total electricity consumption, while my country's lighting electricity consumption accounts for about 12% of the country's total electricity consumption. Vigorously promoting green lighting and lighting energy-saving technologies is of great significance for building a resource-saving and environment-friendly society. With the increasingly serious work of energy conservation and emission reduction, countries around the world have introduced corresponding policies, and low-energy lighting facilities will become the mainstream. ...
