AI Technical Summary

Benefits of technology

The technical feature described by this patented technology relates to changing how we see things on our screens with clear plastic panels made from special materials called LAMBAR (Luminescent Material). This material allows lights to pass easily while still giving them their original colors or reflective qualities like ice flakes. Additionally, it does make sure they don’t scatter too much light during use without getting damaged over time due to its durability against weather conditions such as rainwater. Overall, these improvements enhance both visibility and security at different locations throughout the world.

Problems solved by technology

This patented technology addresses issues related to security, privatization, and illumination while still being able to provide both opaque and clear windows without compromising their ability to see through them. Interlayers made from special materials are used between two layers of glass to create an enclosed space where there aren’t any direct visibility (no shade). When these products come wet they lose its functionality due to absorption of moisture and tearing off easily during cleanings. To solve this problem, certain films like those described earlier were developed specifically for making laminaquid-coverage glasses which offer better visual clarity compared to regular ones.

Abstract

The invention provides a laminated glass intermediate film with shielding capacity and high transparency as well as a preparation method thereof. The laminated glass intermediate film with shielding capacity and high transparency comprises raw materials in percentage by weight as follows: 93.2%-94.7% of EVA (ethylvinylacetate), 0.5%-2% of an inorganic additive, 2%-3% of an organic additive, 0.8%-1.6% of a peroxide crosslinking agent, 0.2%-0.5% of an assistant crosslinker, 0.2%-0.6% of a phosphite antioxidant, 0.2%-0.5% of an HALS (hindered amine light stabilizer) and 0.2%-0.6% of a coupling agent, wherein the content of vinyl acetate in EVA is 28%-33%. The laminated glass intermediate film has excellent shielding effect, has higher glass bonding strength and has good environmental aging resistance.
