Abstract

The invention discloses a high-performance PVB heat insulation resin film. The high-performance PVB heat insulation resin film comprises, by mass, 0.1-0.5% of tungsten oxide nanometer slurry containing tungsten oxide particles with diameters less than 20nm, 50-80% of PVB resin powder, 18-45% of a plasticizer, 0.1-1% of an anti-oxidant and 0.05-1% of an ultraviolet ray absorber. The high-performance PVB heat insulation resin film has high visible light transmittance and an infrared ray obstruction coefficient. Compared with PVB heat insulation resin films prepared from nanometer ATO, ITO and AZO, the high-performance PVB heat insulation resin film has a better capacity of obstructing infrared rays with wavelength of 1000nm or less in a near-infrared zone. The invention also discloses a preparation method of the PVB heat insulation resin film.

Description

technical field [0001] The invention relates to a high-performance PVB heat-insulating adhesive film, and furthermore, the invention also relates to a preparation method of the PVB heat-insulating adhesive film. Background technique [0002] PVB is the abbreviation of polyvinyl butyral, which can be produced by condensation reaction between polyvinyl alcohol and butyraldehyde. The U.S. government legislated in 1938 to require the use of PVB as the base material for the front windshield of motor vehicles. After more than 70 years of research and development and practice, PVB is still an essential raw material for the production of laminated glass. When the laminated glass is impacted and broken, the glass fragments still adhere to the PVB film, and the PVB adhesive layer endows the laminated glass with good impact resistance and penetration resistance, while maintaining superior optical properties. [0003] With the development of science and technology, people endow PVB la...
