2results about How to "Improves UV stability" patented technology

The application provides an organic-inorganic hybrid light conversion material, a film composition, a photovoltaic film and application thereof. The organic-inorganic hybrid light conversion material comprises metal halide anions and quaternary phosphonium salt cations. The metal halide anions comprise metal cations and halide ions. The structure of the quaternary phosphonium salt cations is shown in formula (I). In formula (I), n, m and z are independently selected from integers from 0 to 5; X1, X2 and X3 are all C atoms, or at least one of X1, X2 and X3 is an N atom. The organic-inorganic hybrid light conversion material based on the application solves the problem of poor stability of the light conversion material in the prior art.

This application relates to an aging-resistant cable, comprising a conductor and an insulation layer. The insulation layer comprises the following components: polyvinyl chloride (PVC), cerium dioxide, lauric acid, 4-amino-2,2,6,6-tetramethylpiperidine, benzoylacetone, oxaloyl chloride, triethylamine, anhydrous ethanol, an antioxidant, and an ultraviolet absorber. It also relates to a processing method for the aging-resistant cable. This application has the following advantages and effects: The reaction of cerium dioxide with lauric acid allows metal ions and carboxyl groups to form coordinate bonds, achieving chemical anchoring and generating hydrophobic rare earth carboxylates, improving compatibility with PVC, inhibiting nanoparticle aggregation, promoting uniform dispersion, and providing thermal and light stabilization. Furthermore, the reaction of 4-amino-2,2,6,6-tetramethylpiperidine, benzoylacetone, and oxaloyl chloride yields a free radical scavenging ability with metal chelating capacity and hindered amines, enhancing the thermal and photo-oxidative aging resistance of the PVC cable material.
