Abstract

The invention belongs to the technical field of near-infrared ray transmission materials, and discloses a polycarbonate-organosiloxane copolymer material capable of selectively transmitting near-infrared rays. The product prepared from the material has higher low-temperature impact resistance and near-infrared ray transmission selectivity. The material comprises 94.1-98.7wt% of polycarbonate-methylsiloxane copolymer, 0.1-0.3 wt% of flame retardant, 1-4 wt% of infrared penetrant, 0.1-1 wt% of ultraviolet blocking agent, 0.1-0.5 wt% of antioxidant and 0-0.1 wt% of lubricant. The polycarbonate-organosiloxane copolymer selected as the substrate has better mechanical properties than the existing material, and has higher low-temperature impact resistance and high near-infrared transmittance. By selecting the perylene organic pigment as the near-infrared penetrant, the material can implement very high visible light covering performance, near-infrared region transmittance and selectivity for multiple colors.

Description

technical field

[0001] The invention belongs to the technical field of near-infrared transmission materials, in particular to a polycarbonate-organosiloxane copolymer material which selectively transmits near-infrared rays. Selective permeability. Background technique

[0002] The wavelength range of visible light is between 350-770nm, and electromagnetic radiation of different wavelengths gives people different color perceptions: 350-455nm is purple; 455-492nm is indigo; 492-577nm is green; 577-597nm is yellow; 597nm -622nm is orange; 600-770nm is red. The wavelength range of infrared rays is from 770nm to 400μm. Infrared rays can be divided into three bands: 780-1500nm is the near-infrared region, 1500-6000nm is the mid-infrared region, and 6000nm-1000μm is the far-infrared region. The heat in sunlight is mainly transmitted through electromagnetic waves in the near-infrared region.
