AI Technical Summary

Benefits of technology

The present inventors have discovered that certain types of chemical compounds called beta-monooxygermanium propionate(BMGPM) and its dimers exhibits strong adhesivity towards various surfaces due to their unique structure. These chemistries also reduce volatility during storage without losing fluidity at room temperatures. They help create stronger coatings on metal substrates like steel plating. Additionally, they provide improved moistenability and durable finishes over time. Overall these technical results lead to superior qualities in paints and protect against damage caused by lightning.

Problems solved by technology

The technical problem addressed in this patented text relating to improving the quality and efficiency of producing high-quality liquid crystal displays without harmful emissions associated with traditional methods involving organic solvent systems. Current solutions involve adding certain ingredients like formaldehydes and dimercapto compounds to achieve desired properties while reducing their negative impact on human health.

Abstract

The invention discloses benzene-free type high-gloss and high-solid-content acrylic resin and a preparation method thereof, and belongs to the technical field of paints. The benzene-free type high-gloss and high-solid-content acrylic resin is prepared from the following raw materials by mass: 8 percent to 15 percent of n-butanol, 10 percent to 17 percent of butyl acetate, 0.5 percent to 1 percent of mercaptopropionic acid, 8 percent to 15 percent of hydroxy-propyl acrylate, 5 percent to 15 percent of lauryl methacrylate, 15 percent to 50 percent of iso-bornyl acrylate, 5 percent to 10 percent of glycidyl methacrylate, 3 percent to 8 percent of butyl methacrylate and 2 percent to 3.5 percent of 2,2'-azobis(2-methylpropionitrile). By utilizing a ratio and a combination of the iso-bornyl acrylate and the lauryl methacrylate, the resin also has excellent flexibility and anti-impact capability under a high gloss condition even if no benzene exists; the polarity and viscosity of the resin are reduced and the solid content being 85 percent becomes possible.
