Problems solved by technology

[0004] In the prior art, PC material is mostly used for the light-transmitting cover of LED lamps. This material has the advantages of high strength and elastic coefficient, high impact strength, and wide applicable temperature range. However, if the strength of the material is to be further improved at this stage, it is necessary to increase The thickness of the material itself is used to achieve the required strength, and the material is easily bent during use and is not durable
Moreover, the light directly penetrates the lampshade, which is very dazzling and easy to hurt the eyes. Long-term use of the eyes will cause irreparable damage, which is not beneficial to human health.

Abstract

The invention provides a nanoscale high-strength light-diffusion material as well as a preparation method and application thereof. The nanoscale high-strength light-diffusion material is mainly prepared from the following raw materials in parts by weight: 70-90 parts of polycarbonate, 5-8 parts of nano-fiber whisker, 20-30 parts of organic silicon light diffusion agent, and 5-8 parts of organic nanometer composite material. The preparation method comprises the following steps: uniformly mixing the raw materials, and extruding and shaping the mixture at the temperature of 245-320 DEG C, so as to obtain the nanoscale high-strength light-diffusion material. The nanoscale high-strength light-diffusion material provided by the invention is applied to LED lamp shades, lighting tubes, lamp boxes and liquid crystal displays. The nanoscale high-strength light-diffusion material provided by the embodiment of the invention has the great functions of reducing the material thickness and guaranteeing the product strength, and is good in bending resistance, and the nanoscale diffusion light extraction effect is achieved after light passes through a lamp shade; besides, the nanoscale high-strength light-diffusion material is less prone to deformation after long-term use, and is long in service life.

Description

technical field [0001] The invention relates to the field of nanomaterial processing, in particular to a nanoscale high-intensity light diffusion material and its preparation method and application. Background technique [0002] LED is the abbreviation of English light emitting diode (light emitting diode). Its basic structure is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wires, and then The surrounding is sealed with epoxy resin to protect the inner core wire, and finally the shell is installed, so the LED lamp has good shock resistance. [0003] LED lights are widely used due to the following advantages: energy saving; long life; good applicability, because of the small size of a single LED, it can be made into any shape; short response time, which is ns (nanosecond) level response time, while ordinary The lamps have a response time of...
