Abstract

The invention relates to a high-mid-infrared barrier and high-light transmittance PVB film and a making method thereof. The method comprises the following steps: completely dispersing a nano-DST novel dispersion nano-material used as functional particles by an organic solvent, a dispersant and a plasticizer to prepare a dispersion, extruding the dispersion through a double screw extruder, and carrying out tape casting to produce the PVB film with high mid-infrared barrier and high light transmittance. The high-mid-infrared barrier and high-light transmittance PVB film produced in the invention has the advantages of excellent mechanical properties, super strong mid-infrared barrier and reflectivity, significant reduction of the cost, and very good market promotion and application prospects.

Description

technical field [0001] The invention relates to a PVB film with high mid-infrared barrier and high transmittance and a preparation method thereof, in particular to a heat-insulating film with a mid-infrared barrier of more than 90% and a light transmittance of more than 90% and a preparation method thereof. Background technique [0002] In 1938, the United States passed the law of using polyvinyl butyral (hereinafter referred to as PVB) film laminated glass on automobiles, which has opened the door to a large number of PVB films. After more than half a century of development, people have put forward more and more requirements for PVB diaphragms. [0003] Energy conservation and environmental protection are the eternal themes of economic development in the world today. Against the background of global warming, the "low-carbon economy" based on low energy consumption, low pollution, and low emissions has become a global hotspot. With the development of science and technology,...
