Problems solved by technology

However, this reference document has the following disadvantages: 1. The consumption of the main flame retardant is relatively large, and the impact resistance of the polycarbonate material obtained is relatively poor, which can only reach the IZOD notched impact strength of 100-200, and it is easy to assemble the product. Fragmentation, in addition, it will cause the product to turn yellow easily in the later stage, and the product quality will decline; 2

Abstract

The invention relates to the technical field of polycarbonate material, particularly to high light-transmittance and high flame-retardant polycarbonate material. The polycarbonate material contains the following constituents and materials by weight: 94.8-99.5% of polycarbonate, 0.1-0.3% of fire retardant A, 0.1-3.5% of fire retardant B, 0.1-0.3% of antioxidant A, 0.1-0.3% of antioxidant B, 0.1-0.2% of a lubricating agent and 0-0.6% of light stabilizer, and the sum of the weight percentages of the constituents is 100%. The preparation method comprises the steps of putting the constituents except for the polycarbonate into a high-speed mixer to uniformly agitate, putting the polycarbonate and uniformly mixed material into the high-speed mixer to carry out three-segment agitation, and putting the material into a double-screw extruder to extrude and pelletize. The polycarbonate material disclosed by the invention has the advantages of high light transmittance and high fire resistance and the like, can meet the requirements of a lampshade for outdoor illumination, and is simple in process and beneficial for generalization and application.

Description

technical field [0001] The invention relates to the technical field of polycarbonate materials, in particular to a polycarbonate material with high light transmittance and high flame retardancy and a preparation method thereof. Background technique [0002] Light-emitting diodes (Light Emitting Diode, LED) are increasingly widely used in the fields of display, transportation, electrical appliances and lighting due to their small size, long life, rich color rendering and outstanding energy-saving and environmental protection characteristics. , one of the key technologies for cleaner production and sustainable development. [0003] Due to the light-emitting characteristics of its point light source, LEDs have disadvantages in the field of lighting, such as small lighting area and low lighting brightness, compared with conventional light sources. In order to make up for the lack of application of LED light sources in the field of lighting, it is necessary to use special materi...
