Abstract

The invention discloses a heat-insulating ultraviolet-resistant glass sticker film and a preparation method therefor. The preparation method comprises the steps: S1: dispersing a salicylate compound and PET resin into an aqueous solution of ethanol, so as to form a coating solution; S2: adding metal oxide solid particles into a fluidized-bed reactor, and introducing coating solution entrained supercritical carbon dioxide fluid to coat surfaces of the metal oxide solid particles with the salicylate compound and the PET resin, so as to obtain modified metal oxide solid particles; and S3: uniformly mixing the modified metal oxide solid particles, a couplant, additives and PET to form a casting solution, and pouring the casting solution into a mold, thereby obtaining the glass sticker film. According to the preparation method for the glass sticker film, disclosed by the invention, the heat-insulating and ultraviolet-resistant properties of the glass sticker film are improved, the global performance of the glass sticker film can be more uniform, the service life of the glass sticker film is prolonged, and thus, large-scale popularization and application are better facilitated.

Description

technical field [0001] The invention relates to the technical field of glass film, in particular to a heat-insulating and anti-ultraviolet glass film and a preparation method thereof. Background technique [0002] Glass doors and windows are thin-walled enclosure structures in buildings, and the energy lost through glass doors and windows accounts for 40% of the building's energy consumption. Therefore, taking energy-saving measures for glass is becoming an urgent task. As government departments pay more and more attention to energy-saving projects, glass film has been widely applied to glass doors and windows of various buildings. Glass film can block 45-85% of direct sunlight heat from entering the room in summer, and can reduce heat loss by more than 30% in winter. [0003] In addition to the heat insulation requirements of glass film, good heat insulation and perspective, the requirements for anti-ultraviolet rays are also becoming more and more stringent. When the ski...
