Abstract

Disclosed is a transparent, flame-retardant thermally-insulating, UV-blocking polymer composite film, comprising sequentially from the top: a flame retardant layer, a base layer, a thermal insulation layer, and a UV-blocking layer, having a total film thickness of 1um to 500um, visible light transmittance greater than 80%, UV light transmittance less than 1%, and near-infrared transmittance less than 10%. Also disclosed is a preparation method for the present transparent, flame retardant thermally-insulating, UV-blocking polymer composite film, the technical processes whereof are simple and easy to execute, involve low production costs, and are suitable for industrial mass production. The present transparent, flame retardant thermally-insulating, UV-blocking polymer composite film can be used on such transparent materials and items as glass, windows, protective films, containers and electronic components, and has applications in such fields as construction, transportation, electronics, aerospace and medicine.

Description

technical field [0001] The invention relates to the field of polymer-inorganic nanoparticle synthetic composite films, in particular to a transparent flame-retardant, heat-insulating and anti-ultraviolet polymer composite film and a preparation method thereof. Background technique [0002] In recent years, the Party Central Committee and the State Council have successively issued clear texts stating that the country consumes 20% of energy, and energy conservation has received unprecedented attention from the central government. With the successive promulgation of national energy-saving policies, energy-saving has set off an upsurge in the whole society. [0003] In this energy-saving upsurge, energy-saving glass film has become the biggest highlight of the new economic growth. Looking at the glass film market in China, whether it is the construction industry, the automobile industry, or IT products, the potential demand for glass film is amazing, so it is of great strategic...
