Problems solved by technology

However, the full coverage of the coating will inevitably have a great impact on the light transmittance; and if the material with thermal insulation function is blended with the matrix resin of the window film, since most of the thermal insulation materials are inorganic substances, it is different from The compatibility and dispersion of the matrix resin is poor, which will eventually lead to a decrease in light transmittance and mechanical properties

Abstract

The invention relates to the technical field of fenestrated membranes, in particular to thermal insulation master batch as well as a BOPET fenestrated membrane and a preparation method. The thermal insulation master batch comprises polyester resin, a thermal insulation composition and a dispersing agent, wherein the thermal insulation composition is a core-inner shell-outer shell structural composition, a core is polyacrylonitrile carbonized fibers, an inner shell is a titanium dioxide layer, and an outer layer is polyacrylamide layer. By virtue of the heat absorption effect and far infrared effect of the polyacrylonitrile carbonized fibers, an ultraviolet shielding effect and reflection of titanium dioxide and the condensation effect and light absorption effect of polyacrylamide, the BOPET fenestrated membrane has good light transmission, thermal insulation performance and heat retaining property, and the application prospect is promising.

Description

technical field [0001] The invention relates to the technical field of window films, in particular to a heat-insulating masterbatch, a BOPET window film and a preparation method. Background technique [0002] With the country's increasingly positive attitude towards "energy saving and emission reduction" environmental protection, window film has become one of the beneficiary industries under the policy of energy saving and environmental protection, and its future development prospects in my country are also very broad. Window film is mainly used for automobile glass and building door and window glass. It is pasted on the glass surface to improve the performance and strength of the glass, and to make it have thermal insulation, heat insulation, energy saving, explosion-proof, beautify the appearance, hide privacy and safety. Protection and other functions. [0003] Thermal insulation is one of the important properties of window film. In order to make the window film have he...
