Product introduction
Ultraviolet absorber is the most widely used class of light stabilizer, according to its structure can be divided into salicylate, benzophenone, benzotriazole, substituted acrylonitrile, triazines, etc., the most widely used in industry for benzophenone and benzotriazole. The quenching agent is mainly a metal complex, such as the divalent nickel complex, and often used with ultraviolet absorber, which has a synergistic effect.
Effect
Ultraviolet absorber is a kind of light stabilizer that can absorb the ultraviolet part of sunlight and fluorescent light sources without changing itself.
Since sunlight contains a large amount of ultraviolet light that is harmful to colored objects, its wavelength is about 290-460 nanometers. These harmful ultraviolet light causes the color molecules to eventually decompose and fade through chemical oxidation-reduction (Redox reaction).
Methods to prevent harmful UV light from damaging color are both physical and chemical.
Here we only briefly introduce chemical methods, that is, using ultraviolet absorbers to effectively prevent or weaken the color damage of protected objects.
UV absorbers should meet the following conditions
① It can strongly absorb ultraviolet rays (especially the wavelength of 290-400nm); ② It has good thermal stability and will not change due to heat even during processing, and its thermal volatility is small; ③ It has good chemical stability and does not interact with the materials in the product. The components have adverse reactions; ④ Good miscibility, can be evenly dispersed in the material, no blooming, no bleeding; ⑤ The absorber itself has good photochemical stability, does not decompose, does not change color; ⑥ Colorless, non-toxic, Odorless; ⑦ resistant to soaking and washing; ⑧ cheap and easy to obtain; ⑨ insoluble or difficult to dissolve in water.
UV absorbers can be divided into the following categories according to their chemical structures: salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines and hindered amines.
