On the other hand, the road safety indicator of the present invention is to emit light from the rod itself by adding a luminescent material (fluorescent pigment or luminous pigment) to the synthetic rubber when manufacturing the line rod, which is a light emitter, so that the driver can easily identify with the naked eye when driving the vehicle day and night It was made. Here, look at the manufacturing method of the light emitter in more detail as follows.

First, a synthetic rubber particle and fluorescent pigment are mixed and blended in a ratio of 100: 2 to 3. A luminous pigment may be used here instead of the fluorescent pigment, and the ratio is blended at 100: 1-5. The blend blended in this proportion is passed through an extrusion apparatus at a first set temperature (150 degrees to 200 degrees). The small particles are then granulated (pellets) through the extrusion device. The small particles and the compound are previously shaped at a second set temperature (170 to 220 degrees) at least 20 degrees higher than the first set temperature. Injection molding is performed by injection into the completed mold. Finally, the injection molded product is cooled. As described above, the production method of the line rod of the present invention is injection molding with a small granulated compound made by dissolving a blended compound at a predetermined ratio, so that the fluorescent pigment is mixed evenly (evenly) with the synthetic rubber so that the quality of the product is uniform. This is done).

On the other hand, when the luminescent material (fluorescent pigment or luminous pigment) is mixed below the reference value (mixing ratio), the luminescence purpose cannot be achieved, and when the pigment is mixed above the reference value, the production cost increases (fluorescent and luminous pigment). Is expensive, and the above-mentioned reference value is most preferable in terms of cost and attainment of purpose. The reason why the second set temperature is at least 20 degrees higher than the first set temperature is because the compound can be dissolved at least higher than the first set temperature in order to dissolve the compound prepared by heating the melt at the first set temperature.

On the other hand, the synthetic rubber is a styrene-based elastomer (styrene elastomer) is a thermoplastic resin that has improved the heat resistance and weather resistance temperature resistance while having the elasticity of the rubber mainly composed of styrene block copolymer (styrene block copolymer), this material is a general Like plastic, it has the advantage of easy processing such as extrusion and injection.
