Description

Transparent heat insulation ultraviolet light-colored film and preparation method thereof

The invention relates to the field of polymer materials, in particular to a transparent heat insulation ultraviolet light-colored film and a preparation method thereof. Background technique

With the increasing global warming and energy shortages and the large number of applications of glass in construction vehicles, functional protective films such as heat-insulating, UV-blocking, explosion-proof, and energy-saving protective films are becoming more and more important. The energy of sunlight is composed of 53% infrared, 44% visible light and 3% ultraviolet energy. The thermal insulation UV film mainly reflects and absorbs infrared ultraviolet light in sunlight and varies according to visible light transmittance. Corresponding to the amount of solar energy.

With the development of technology, various technologies have been formed to achieve the above objectives. With the development of technology, various technologies have been formed to achieve the above objectives.

Chinese patent CN200310111067.4, the patent name is Chinese patent CN200310111067.4, which is used to thermally decompose transparent film after chemical deposition of nano-Sn0 ₂ doped with F and Mn, but this method is generated by high temperature thermal decomposition. The nano-film layer is not suitable for direct production on PET film, and the process cannot ensure large-scale continuous production.

The Chinese patent CN98100128.9 using sputtering method heat-sputters an ITO material onto a glass surface, which is not suitable for mass production on PET.

There are also processes that use relatively economical nano-insulation coatings and then apply them to the surface of PET films, such as the Chinese patent CN200410014672.4, etc., but the PET materials are difficult to adhere and the coating process has the disadvantage of uneven color and multi-color particles.

Patent CN1126139A describes a polyester film which is completely light-shielded by adding 10% or more of titanium dioxide material, and has the disadvantages of uneven pigment dispersion and opacity.

DuPont's patent CN1284913A introduces a titanium dioxide material by adding 10% or less It is possible to obtain a polyester film which is almost opaque, and has the disadvantage that it cannot block infrared rays.

The magnetic recording film invented by Diafoil Hoechst contains a polyester film in which a fluorescent particle is overlaid with a white pigment. The film has two added layers, no transparency, and no UV-blocking function.

Patent CN101195685A describes a full-dull color insulating film produced by using a polyester masterbatch and a production process thereof; Patent CN102241177A describes a color polyester film directly pigmented with a pigment and a method for producing the same. The products obtained in these two patents can only be used in the fields of tape, food packaging, etc., because the obtained products have no ultraviolet insulation function. Summary of the invention
