Abstract

This invention relates to a method for preparing low-radiation heat-insulating transparent film for controlling sunlight. The film is composed of: organic polymer 70-99.9 wt. %, doping metal oxide nanoparticles 0.1-30 wt. % and adjuvant 0-29.9 wt. %. The method comprises: (1) uniformly dispersing the doping metal oxide nanoparticles into a dispersing medium, mixing with the organic polymer and the adjuvant, and drying to obtain master batches; (2) plasticizing, smelting or extruding and blowing, calendaring, stretching, extruding and casting to obtain the film. The film can be used as the coating film for architecture glass, automobile window and ship window, and has such advantages as high visible-light permeability, good sunlight obstructing effect, good anti-electrostatic effect, and good electromagnetic radiation resistance.

Description

technical field [0001] The invention relates to a composite film of organic macromolecules and nano-inorganic particles, in particular to a sunlight-controlling, low-radiation, heat-preserving, energy-saving transparent film and a preparation method and use thereof. Background technique [0002] 98% of the solar energy projected on the surface of the earth has a wavelength in the range of 0.3-2.5 μm, which can be divided into three parts according to its wavelength, namely ultraviolet light, visible light and infrared light. Ultraviolet light (accounting for 3%) is invisible light with a wavelength of less than 380nm; visible light (accounting for 45%) has a wavelength of 380-780nm; infrared light (accounting for 49%) is also invisible and its wavelength is higher than 780nm. The thermal insulation and energy-saving effect of glass or windows is usually characterized by the value of shading coefficient (Sc) and heat transfer coefficient (U), and these two parameters can be u...
