紫外线吸收剂
目前较为理想的紫外线吸收剂/光稳定剂多为复配型的,特别是以水杨酸酯类、苯酮类、苯并三唑类、取代丙烯腈类、三嗪类与受阻胺类复配,可取得比任何单独紫外线吸收剂更为理性的效果。紫外线吸收剂的使用领域:聚合物(塑料等),涂料(汽车喷漆,建筑物涂饰),印刷油墨,染色/印花纺织品的后处理,防晒化妆品。
At present, the most ideal UV absorbers / light stabilizers are compounded, especially salicylates, benzotriazoles, substituted acrylonitrile, triazines and hindered amines, which can achieve more rational effect than any single UV absorber. Application fields of UV absorbers: polymers (plastics, etc.), coatings (car spray painting, building finishing), printing ink, dyeing / printing textile post-treatment, sunscreen cosmetics.
为一高效光稳定剂,具有广泛的紫外线吸收特性,挥发性低,适用于聚苯乙烯,聚甲基丙烯酸甲酯,聚酯,硬质聚氯乙烯,聚碳酸酯,ABS树脂等。在透明制品及高温加工的工程塑料中尤具效果。与抗氧剂并用有优质的协同效应,可提高制品的耐候性和热氧稳定性。
It is a high efficiency light stabilizer with wide ultraviolet absorption characteristics and low volatility. It is suitable for polystyrene, polymethylmethacrylate, polyester, rigid polyvinyl chloride, polycarbonate, ABS resin, etc. It is especially effective in transparent products and engineering plastics processed at high temperature. It can improve the weather resistance and thermal oxygen stability of the products.
