Description

This invention has strong scratch resistance and wear resistance of non-adhesive electrostatic glass mirror mask, which belongs to the field of film technology, especially self-adhesive metal film used for architectural residential glass. Regarding glass mirror film.

Architectural glass film is mainly used for architectural window glass, door glass, and curtain wall glass in houses, office buildings, commercial facilities, etc. By applying it to the surface of architectural glass, it improves the performance of the glass, provides heat insulation, It is possible to add functions such as heat shielding, energy saving, UV protection, appearance beautification, privacy protection, explosion protection, safety, and protection. Additionally, even if the glass breaks for some reason, the fragments will stick to the construction safety film, reducing splashing and falling. At the same time, due to the strength of the film body, it can withstand external forces along with the glass, and if the glass breaks, the film alone can withstand a certain external force for a certain period of time.

Yet another embodiment is a non-adhesive electrostatic glass mirror film with strong scratch resistance and wear resistance, wherein the wear and scratch resistance layer may be a nano-aluminum trioxide coating.

The beneficial effect of this invention is that by using a special scratch-resistant super wear-resistant PVC film layer and an outermost wear-resistant anti-scratch layer, it is not only cost-effective but also self-contained for architectural glass. The adhesive metal film has strong scratch resistance and wear resistance, high hardness and long service life. The present invention also has the advantage of high cost performance.
