Abstract

The invention relates to a high thermal-insulating eye and skin protecting type PVB film and a protection method thereof. The film is formed by using Nanometer DOT as functional particles, processing with organic solvent, dispersing agent, coating agent and plasticizer and forming into dispersion liquid by ultrasonic dispersion, then being extruded by a double-screw extruder, and finally tape casting. The nanometer dispersing agent produced according to the production method can effectively improve the problems of lamination, agglomeration of nanoparticles, and being incompatible with resin powder; the high thermal-insulating eye and skin protecting type PVB film has excellent mechanical property and superstrong infrared rejection and reflection capacities, and meanwhile has good light transmittance without changing color, and thus can be directly applied to glass deep-processing industry for producing eye-protecting, skin-protecting and safe multifunctional safety glass.

Description

technical field [0001] The invention belongs to the field of glass materials, and in particular relates to a PVB film with high heat insulation, eye protection and skin care 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, people endow PVB laminated glass with more functions, such as heat insulation, discoloration, sound ...
