Abstract

The invention discloses high-performance and high-sunscreen PC polymer. The formula of raw materials comprises an antioxidant, an ultraviolet light absorber, a toughening agent, sunscreen, PP (propene polymer) grafting, a melt index conditioning agent and PC. The high-performance and high-sunscreen PC polymer has a sunscreen effect which is superior to that of other products in the industry, and the average light transmissivity is 0-0.2; simultaneously, the PC polymer is shallower in color and can be easily colored by other colors; and besides, the product has high shock resistance, processing performance and stable quality, and is particularly applicable to manufacture of an LED lamp light shield, an instrument light shield, a light shield decorative accessory and a light barrier.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to PC polymers, in particular to a high-performance and high-light-shielding PC polymer and its preparation method and application. Background technique [0002] LED (Light Emitting Diode), or light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. It is small in size, low in power consumption, high in brightness, low in heat, durable and environmentally friendly. These inherent characteristics determine that it is the most ideal light source to replace traditional light sources and has a wide range of uses. It can be used as a display light source for display screens, traffic signals, living lighting, and industrial lighting. The wide application of LED lamps also puts forward higher requirements for the materials of its accessories. For example, the high brightness of the LED light source has higher requirements on...
