Embodiment 1

[0026] The special high reflective PMMA masterbatch for traffic of the present embodiment, its component ratio by weight is: 87 parts of matrix polymethyl methacrylate, 5 parts of organosilicon light diffusing agent, 4.4 parts of optically active adsorbents, dispersant EBS. .6 parts, 3 parts of high transparency orange dye.

[0027] The preparation method of the traffic-specific high-reflective PMMA masterbatch of this embodiment is as follows: first, pour the organic silicon light diffusing agent into the optically active adsorbent while stirring, and evenly disperse the organic silicon light diffusing agent in the optically active adsorbent, Ensure that the silicone light diffusing agent is not easy to drift away in subsequent operations. Then add the matrix PMMA and the dispersant EBS into the organic silicon light diffusing agent system, and stir evenly, because the organic silicon light diffusing agent has been pre-wrapped by the optically active liquid adsorbent, when th...

Embodiment 2

[0030] The special high reflective PMMA masterbatch for traffic of the present embodiment, its component ratio by weight is: 88 parts of matrix polymethyl methacrylate, 3.6 parts of acrylate resin light diffusing agent, 0.9 part of organosilicon light diffusing agent, optical rotation 4.5 parts of non-toxic adsorbent, 0.8 parts of dispersant EBS, 2.2 parts of high-transparency dye.

[0031] The preparation method of the traffic-specific high-reflective PMMA masterbatch in this embodiment is as follows: first, pour the above-mentioned light diffusing agent into the optically active adsorbent while stirring, and evenly disperse the light diffusing agent in the optically active adsorbent to ensure light diffusion. The agent is not easy to float away in subsequent operations. Then add the matrix PMMA and the dispersant EBS into the light diffusing agent system, and stir evenly, because the light diffusing agent has been pre-wrapped by the optically active liquid adsorbent, when th...

Abstract

The invention discloses a special high-reflection PMMA masterbatch for transportation, which is characterized in that its components are proportioned by weight: 85-90 parts of matrix PMMA, 3-6 parts of light diffusing agent, 4-5 parts of liquid adsorbent, 0.5-0.9 parts of dispersant, 2-5 parts of high-transparency dye, light diffusing agent is silicone light diffusing agent, and adsorbent is liquid adsorbent with optically active polymethacrylic acid amide as the main body. The preparation method of the above-mentioned masterbatch is as follows: pour the light diffusing agent into the liquid adsorbent while stirring, then add PMMA and dispersant to the light diffusing agent system, stir evenly and put it into the same direction bidirectional Blending, extrusion, traction, and granulation in a screw extruder to obtain master batches. When used as a special traffic lampshade material, the light transmittance is ≥ 88%, and the haze is ≥ 98%. The special high-reflection PMMA masterbatch for transportation prepared by the invention saves the step of modifying the light diffusing agent, reduces the production cost, and is dust-free and environment-friendly during the preparation process.

Description

technical field [0001] The invention relates to a masterbatch and a preparation method thereof, in particular to a high-reflection PMMA masterbatch for traffic and a preparation method thereof. Background technique [0002] Car lights are indispensable in human life. For most car lights, the illumination light is required to have a uniform spatial light intensity distribution. However, almost all light sources work as point light or line light, that is, point light source or line light source. At present, the rapid development of semiconductor light-emitting diodes (LEDs) has brought a revolution to the world's lighting sources, and LEDs are typical point light sources. The LED core has high brightness, energy saving and environmental protection, long life, and small size, but the light-emitting area is also small. In order to achieve uniform illumination, it is necessary to convert the light emitted by the point light source into surface emission. [0003] LED has high br...
