Master batch, polycarbonate cooling film, and preparation method and application of polycarbonate cooling film

The invention discloses a master batch, a polycarbonate cooling film, and a preparation method and application the polycarbonate cooling film, belonging to the technical field of cooling film preparation. The master batch comprises the following components in parts by weight: 98-99 parts of polycarbonate, 0.5-1.5 parts of a near-infrared absorbent, 0.1-0.3 part of a heat insulating agent and 0.05-0.2 part of a coupling agent, wherein the near-infrared absorbent is 2-[3-[1,3-dihydro-1,3-dimethyl-1-(phenylmethyl)-2H-benzo[e]indol-2-ylidene]-1-propylene-1-yl]-1,3-dimethyl-1-(phenylmethyl)-1H-benzo[e]indole. The polycarbonate cooling film is prepared from the following components in percentage by mass: 97 to 98.5% of polycarbonate and 1.5 to 3% of the master batch. The master batch and the polycarbonate cooling film have good ultraviolet ray isolation and heat insulation effects and high light transmittance, and can be applied to preparation of glass films or transparent heat insulation plates. 本发明公开了一种母粒、聚碳酸酯冷却膜
