Abstract

The invention belongs to the technical field of TPU films, and particularly relates to a high-shading type double-color TPU film and a production technology thereof.The two faces of the high-shading type double-color TPU film are a black film and a white film respectively, and the black film is prepared from, by weight, 100 parts of TPU masterbatch and 30-50 parts of silane coupling agent modified carbon black. According to the high-shading type double-color TPU film, the black film and the white film are arranged on the two faces of the high-shading type double-color TPU film respectively, the white film outwards contributes to reflecting light rays and heat and has a good heat insulation effect, the black film can play a shading role, and the black film outwards can effectively absorb heat and contributes to increasing the internal temperature; the double-color TPU film can be applied to scenes with different requirements; besides, the carbon black added in the black film is silane coupling agent modified carbon black, so that the dispersion effect of the carbon black in TPU can be effectively improved, the dispersion uniformity is improved, agglomeration is avoided, the influence on the mechanical property of the film is reduced, and meanwhile, a better shading effect is achieved.

Description

technical field [0001] The application belongs to the technical field of TPU films, and in particular relates to a high light-shielding double-color TPU film and a production process thereof. Background technique [0002] The shading film can be used to block the light to achieve the effect of partial light transmission or complete opacity, so as to realize the control of light and meet the specific shading requirements. It can be used in curtains, darkrooms, clothing fabrics and other fields. Among them, the black and white two-color shading film is a special shading film. If the white side faces outward, the white side can reflect light and heat, which has a good heat insulation effect and meets the requirements of the internal low temperature environment; the black side can play The shading function meets the needs of shading, especially suitable for summer. If the black side is facing outward, the black side can absorb light and heat, which is beneficial to increase the...
