Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a nano heat-insulating PVB interlayer film for laminated glass and its preparation method. Through optimization and improvement of the structure and formula, as well as process improvement of the preparation method, the existing PVB interlayer film is solved. There is no special heat insulation function, and the heat insulation performance is poor, which affects the energy-saving performance of laminated glass. At the same time, the anti-oxidation and anti-yellowing performance of PVB interlayer film is not ideal, and the influence of PVB interlayer film on the mechanical strength of laminated glass is also Issues to be further improved

Abstract

The invention relates to a nanometer heat insulation PVB intermediate film for laminated glass and a preparation method thereof. The nanometer heat insulation PVB intermediate film comprises a modified PVB base film and a heat insulation coating at least compounded on the surface of one side of the modified PVB base film; wherein the modified PVB base film comprises the following raw materials inparts by mass: 200-260 parts of high-viscosity PVB resin, 3-8 parts of silicon dioxide nanoparticles, 4-18 parts of zirconium dioxide nanoparticles, 2-6 parts of nano zinc oxide powder, 20-40 parts ofa plasticizer, 2-8 parts of a film-forming chain extender and 1-5 parts of an antioxidant. The nanometer heat insulation PVB intermediate film prepared by the method has good heat insulation performance and sound insulation performance, the heat conductivity coefficient can be controlled below 0.8 W / (m*K), meanwhile, compared with a traditional PVB intermediate film, the hardness and toughness are improved, and the nanometer heat insulation PVB intermediate film has good light transmittance, good heat stability, excellent oxidation resistance and excellent yellowing resistance.

Description

Technical field [0001] The invention relates to the field of thin film materials, in particular to a nano thermal insulation PVB intermediate film for laminated glass and a preparation method thereof. Background technique [0002] Laminated glass is also called high penetration resistant laminated glass. This product consists of three layers, a layer of polyvinyl butyral (PVB) interlayer film is sandwiched between two pieces of glass, which is bonded at high temperature and high pressure to combine the toughness of plastic with the rigidity of glass. This kind of intermediate film improves the resistance to breakage, the thicker the intermediate film, the stronger the glass. Traditionally, the sandwich structure is reflected in its product name. For example, the 4+0.76+4 specification laminated glass is made of two pieces of 4mm thick glass and a layer of 0.76mm thick PVB interlayer. [0003] Laminated glass plastic film is a polymer formed by the condensation reaction of higher...
