Abstract

The invention provides a high-heat-sealing and high-light-transmittance glass film which has excellent transparency and relatively good heat sealing performance. The glass film is prepared from the following components in parts by weight: 100 parts of polyethylene terephthalate (PET), 3-6 parts of nano ceramic, 10-15 parts of an organic silicon resin adhesive, 5-10 parts of an adhesive and 1-2 parts of a nucleating agent.

Description

technical field [0001] The invention relates to a glass film with high heat sealing and high light transmittance, which is mainly used for the protection of automobile glass and belongs to the application field of polymer materials. Background technique [0002] Automobile glass is not insulated from heat and is not protected from ultraviolet light, so people often paste a layer of protective film on the glass. As a window film protection product, it should have heat insulation and other properties. However, the quality of the films on the market is uneven, and there are many problems. Some films have poor heat sealing performance, and some films have poor light transmittance. [0003] In view of the above technical problems, the present invention provides a glass film with high heat sealing and high light transmittance, which not only has good heat sealability, but also has high light transmittance. Contents of the invention [0004] The purpose of the present invention ...
