Abstract

The invention discloses a PVB (polyvinyl butyral) film for dynamically rejecting infrared rays and resisting ultraviolet rays and a preparation method thereof. The functional PVB film comprises cesium tungsten bronze, antimony indium oxide, indium tin oxide, titanium dioxide, nano carbon spheres, zirconium carbide, PVB resin powder, a plasticizer, a trace improver and the like. The preparation method comprises the following steps: dispersing the cesium tungsten bronze composite nanoparticles with a solvent, adding the plasticizer, stirring uniformly, adding the PVB resin powder and trace improver, thoroughly mixing, and carrying out film formation on the mixture by running to obtain the heat-insulation ultraviolet-resistant PVB film. The ultraviolet rejection ratio of the PVB film is greater than 99.0%, the visible light transmittance is adjustable within the range of 60-85%, and the infrared rejection ratio is up to 80-99%; and the PVB film can be directly used for producing heat-insulation infrared / ultraviolet-resistant safety laminated glass, can be widely used in architectural curtain walls, doors / windows, zeniths, automobile windshields and the like, and is a novel energy-saving film material.

Description

technical field [0001] The invention belongs to the technical field of functional modification and preparation of polyvinyl butyral (PVB) films, and relates to a PVB film that dynamically blocks infrared rays and prevents ultraviolet rays and a preparation method thereof. Background technique [0002] PVB film has good light transmission and strong impact resistance. It is the main interlayer material used to make safety glass. It is used in building curtain walls, doors and windows, zeniths, car windshields, and high-speed rail windows. However, PVB itself has strong light transmission, and the heat insulation effect is not ideal, which may easily cause high indoor temperature. In order to improve the heat insulation effect of glass doors and windows, curtains are generally used to block sunlight, or additional heat insulation and explosion-proof films are attached to the glass. This will increase additional expenses and labor, and to a certain extent affect the permeabili...
