Problems solved by technology

[0004] The traditional processing modification method is to add some inorganic additives, such as silicon dioxide and barium sulfate, to PC or PMMA. Adding these inorganic nanoparticles, the light will undergo countless light refraction through the surface of the tiny particles to achieve light diffusion. That is, the effect of uniform light, but because light cannot penetrate inorganic nanoparticles, the penetrating power is greatly weakened, and the loss is very large

Abstract

The invention discloses a high-fog-degree and high-transparency LED lamp tube material and a preparation method thereof. The LED lamp tube material comprises the following components by weight ratio (%): 97-99% of engineering plastic, 0.3-1% of light-scattering agent; 0.3-1% of dispersant; 0.2-0.6% of color protection agent and 0.1-3% of other additives. The invention uses the engineering plastic PC as a main body, and adds the organic bead resin light-scattering agent, the color protection agent and other additives to carry out extrusion granulation by melt blending. The polycarbonate engineering plastic prepared by the invention can be used for extrusion molding of the LED lamp tube material, not only has good scattering effect but also has high luminousness, and has excellent physical and mechanical performances and simple process. The preparation method of the LED lamp tube material comprises the following process steps: firstly, mixing raw materials in proportion; then sending into a plastic extrusion machine, and controlling the temperature between 250 DEG C and 300 DEG C; and finally, carrying out granulation.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high haze and high transparency LED lamp tube material and a preparation method thereof. Background technique [0002] At present, due to the requirements of environmental protection and energy saving, the demand for LED lights has developed into a trend, but the LED light is strong and dazzling, and the light energy is high. How to make the light of the LED soft and minimize the loss of light energy has become an urgent technical problem to be solved in the application of LED lights today. [0003] To solve this problem, LED lamp shades can be added. PC and PMMA can be used as lampshade materials, but due to the high light transmittance of PC and PMMA, if they are not processed and modified, the light of LED lights will still be strong and dazzling. [0004] The traditional processing modification method is to add some inorganic additives, such as silicon dioxide a...
