Barium sulfate with purity of more than 98 percent, particle size of less than or equal to 80 nanometers, and the addition amount of the barium sulfate is 3 to 11 percent by weight.

Technical Field

The invention relates to the field of LED illumination, atomizes glare generated by the light emission of an LED chip, reduces the damage to a retina, and is used for manufacturing a modified ABS of a lamp tube and a lampshade.

Background

The lamp manufactured by the LED chip is an environment-friendly and energy-saving lamp, and the spectrum generated by the LED chip works in the 480 nanometer waveband of 450 plus materials is coated with the fluorescent agent. Thereby exciting and converting into white light, and generating a part of glare in the white light, which has harm to human retina.

Disclosure of Invention

The invention reduces glare produced by the LED chip during working, enables the LED chip to transmit soft light produced by the lamp tube and the lampshade, and reduces uncomfortable feeling to human body and retina.

In order to improve the glare defect generated by the LED chip, the optical ABS is modified by adding substances with atomized spectra, so that the optical ABS keeps high light transmittance, and simultaneously, the glare and unfavorable spectra generated when the LED chip works are eliminated.

The invention provides a preparation method of a nano barium sulfate and nano holmium oxide and optical ABS composite material.

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The technical scheme for solving the technical problems is that barium sulfate and holmium oxide are prepared to be nano-scale, and after the barium sulfate and holmium oxide are prepared to be nano-scale, the specific surface area is large, the activation degree is high, the atomization degree is good, the addition amount is small, the basic mechanical property of the original optical ABS particles is not damaged, and the rigidity and the temperature resistance of the particles can be improved. It is characterized in that the particle size of optical-grade polypropylene ABS is less than or equal to 5 microns. The purity of holmium oxide reaches more than 99.5%, the particle size of holmium oxide is less than or equal to 50 nanometers, and the addition amount is 2-9% by weight. Barium sulfate with purity of more than 98 percent, particle size of less than or equal to 80 nanometers, addition amount of 3 to 11 weight percent, meeting the requirement of glare intensity according to needs, selecting a proper material ratio, adopting a blending method, putting into a vibration mixer together, and rotating at the rotating speed of less than or equal to 500 rpm for less than or equal to 150 minutes.

According to the LED fluorescent lamp tube extruded by the extruder by using the ABS modified above, under an electron microscope, nano holmium oxide and nano barium sulfate form a grid layout of nano crystals in the ABS, so that glare emitted by an LED chip can be effectively improved, the light is soft, and damage to a retina and uncomfortable feeling are improved.

The invention has the following advantages: the compound taking nano holmium oxide and nano barium sulfate crystals as cores is formed, the grid layout is generated in the ABS, the addition amount is small, granulation is not needed, the transparency is maintained, and the physical properties of the original ABS are improved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
