Highly-transparent weathering-resistant flame-retardant lampshade material for emergency lights, and preparation method thereof

Abstract

The present invention discloses a highly-transparent weathering-resistant flame-retardant lampshade material for emergency lights, wherein the raw materials comprise, by weight, 70-80 parts of a poly1,4-cyclohexylene dimethylene terephthalate resin, 15-25 parts of polymethyl methacrylate, 3-5 parts of nano-silica, 2-4 parts of silicon carbide, 5-10 parts of sodium dodecyl sulfate, 2-6 parts of graphene, 2-5 parts of magnesium hydroxide, 4-6 parts of decabromodiphenyl oxide, 2-4 parts of zinc borate, 1-2 parts of a light diffusing agent, 2-3 parts of carboxymethylcellulose, 1-2 parts of trichloroisocyanuric acid, 5-10 parts of polytetrafluoroethylene ultra-fine powder, 3-5 parts of a coupling agent, 10-16 parts of a processing aid, and 1-3 parts of a barium zinc stabilizer. The highly-transparent weathering-resistant flame-retardant lampshade material of the present invention has advantages of good thermal conductivity, high light transmittance, good light dispersing performance, good flame retardancy, good chemical stability, high use value and good application value; and the preparation method has advantages of low material cost, easily available raw material, and simple process.

Description

technical field [0001] The invention relates to the technical field of lamp materials, in particular to a highly transparent, weather-resistant and flame-retardant lampshade material for emergency lamps and a preparation method thereof. Background technique [0002] Emergency lights are an indispensable and important component of the fire safety system; emergency lights are mandatory to be installed in public buildings, high-rise buildings, hotels, and crowded places and require regular maintenance. The function of the emergency light is to provide the minimum illumination for the designated safe passage within a specific time when the general lighting in the building cannot work normally due to fire or other unpredictable disasters. Emergency lights can also provide lighting signal signs to help safe evacuation when the general lighting in the building does not work normally, and clearly indicate the direction change of each channel to help trapped people evacuate in an ord...

Problems solved by technology

At the same time, because the LED lamp will generate a lot of heat when it is working, and the excessive heat accumulation in the lampshade will cause the danger of fire, and the existing LED lampshade material is not good in flame retardancy, and it cannot effectively prevent the spread of the fire in case of danger.
