Method for preparing low-emission thermal insulation film for laminated glass

Abstract

The invention relates to a preparation method of a low-emission thermal insulation film for laminated glass. The preparation method is characterized by taking a PVC film, a PET film, a PP film or a BOPP film as a carrier, and adding a treatment agent (2) with the concentration of 1-5% to waterborne resin and acetone, butyl acetate or ethanol or to a mixed solution thereof to obtain surface treatment solution to be applied to a surface of the low-emission thermal insulation film; or performing hot pressing on the surface at the temperature of about 50-120DEG C and the pressure of about 1-3kg / cm; or modifying the film surface by means of corona or a combination of the methods; and making coating by purchased or self-made ATO, tin indium oxide or tin oxide or combination paste thereof as well as waterborne acrylic resin, waterborne polyurethane resin or waterborne epoxy resin and applying the coating to the film to form a thermal insulation reflector which is closely adhered to the film; and then adding a treatment agent (1) to the waterborne acrylic resin to make treatment solution, and performing secondary treatment on the film surface with the thermal insulation reflector and the film surface without the thermal insulation reflector so as to obtain the low-emission thermal insulation PVB film closely adhered to the laminated glass.

Description

Technical field: [0001] The invention relates to a preparation method of a low-e film which can be used for laminated glass. It is mainly used in the fields that need to effectively isolate the ambient temperature and the internal space temperature. Background technique: [0002] The insulating glass currently on the market is mainly aimed at monolithic low-e glass and hollow low-e glass. Single-piece low-e glass is often made into double-layer low-e glass because its k value cannot meet the national energy-saving requirements, but its cost is much higher than hollow low-e glass, so hollow low-e glass is currently the most widely used energy-saving glass. However, laminated glass does not have a good energy-saving effect and cannot be used on a large scale in the energy-saving field. [0003] In the process of producing laminated glass, the Chinese patents that have been declared include: Patent No. 03113066.6 "Laminated Glass" and Application No. 00138041.9 "Low-E Lamina...

AI Technical Summary

Problems solved by technology

The first patent only mentioned how to improve the safety performance and aesthetic performance of laminated glass by improving the structure of laminated glass, and did not involve the energy-saving effect of laminated glass

The second patent is for laminated glass with pet anti-radiation film, but its patent is only for how to make anti-radiation glass through the film
