Infrared absorbent dispersion, transparent heat-insulating organic glass, and manufacturing method thereof

Abstract

A dispersant of an infrared absorbent dispersion is distributed in an outer layer of an infrared absorbent to form an independent unit dispersed in an organic solvent; the molecular structure of the dispersing agent has an active unit capable of undergoing a free radical copolymerization reaction with a methyl methacrylate monomer and/or a group capable of generating intermolecular forces with polymethyl methacrylate; and the organic solvent can be mutually soluble with the methyl methacrylate monomer and the polymethyl methacrylate. Due to the stable dispersion and suspension of the infrared absorbent in a dispersion and the high inter-miscibility and adaptability of the dispersion and the matrix material, the infrared absorbent is evenly dispersed in the organic glass. The infrared absorbent is tightly bound to the matrix via the dispersant on the outer layer, such that the organic glass is uniformly transparent under visible light and can uniformly block infrared light.
