Problems solved by technology

[0008] In order to solve the problems raised in the prior art, the present invention proposes a heat-insulating and sound-insulating PVB film and a preparation method thereof. By adopting a new process formula, the heat-insulating and sound-insulating laminated PVB diaphragm is successfully developed, which solves the problem of heat-insulating and sound-insulating PVB films. Sound insulation PVB film has low light transmittance, large haze, poor heat insulation effect, and poor sound insulation

Abstract

The invention relates to a heat-insulating and sound-insulating PVB film and a preparation method thereof. The heat-insulating and sound-insulating PVB film is produced by a three-layer co-extrusion technology, and is of a structure comprising a heat-insulating layer / a sound-insulating layer / another heat-insulating layer, wherein the heat-insulating layers are prepared by a new nanomaterial heat-insulating technology. The prepared heat-insulating and sound-insulating PVB film has advantages of relatively low haze, high light transmittance, high weather resistance and heat insulating effect obviously superior to those of ATO and ITO heat-insulating diaphragms.

Description

technical field [0001] The invention relates to a thermal and sound insulation PVB film 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 insulation, privacy, anti-theft, etc. [0004] In recent years, with the rapid develo...
