环保无醛负氧离子汽车玻璃膜及其制造方法
By using raw materials with a specific ratio to prepare environmentally friendly formaldehyde-free negative oxygen ion automotive window film, the problem of existing automotive window films being unable to continuously release negative oxygen ions and having poor environmental protection effects has been solved. This results in highly efficient negative oxygen ion release, excellent ultraviolet absorption, heat insulation performance, and mechanical strength.

AI Technical Summary
Existing automotive window films cannot continuously release negative oxygen ions, and their environmental and health benefits are not good.
An environmentally friendly, formaldehyde-free, negative oxygen ion automotive window film is prepared using raw materials in a specific ratio. This includes waterborne polyurethane resin emulsion, cationic waterborne acrylic resin emulsion, and waterborne acrylic modified polyurethane dispersion emulsion, combined with rare earth nano-cerium oxide, metal nano-oxide, glass fiber powder, and other components. The film is prepared by ultrasonic dispersion and ultraviolet lamp curing.
It increases the release of negative oxygen ions in automotive window film, enhances ultraviolet absorption and heat insulation, and also has good weather resistance and mechanical strength.
