Abstract

The invention discloses a heat-insulating and anti-ultraviolet glass film and a preparation method thereof. The preparation method is as follows: S1: dispersing a salicylate compound and a PET resin in an aqueous solution of ethanol to form a coating liquid; S2: dissolving the In the fluidized bed reactor, metal oxide solid particles are passed into supercritical carbon dioxide fluid entrained with coating liquid, so that salicylate compounds and PET resin are coated on the surface of metal oxide solid particles, and modified metal oxides are obtained. Oxide solid particles; S3: Mix the modified metal oxide solid particles, coupling agent, additives and PET uniformly to form a casting solution and pour it into a mold to obtain the glass film. The preparation method of the glass film of the present invention not only improves the heat insulation and anti-ultraviolet performance of the glass film, but also makes the overall performance of the glass film more uniform, prolongs its service life, and is more conducive to large-scale popularization and application.

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...
