Description
技术领域 technical field
本发明涉及一种UV涂料，特别是涉及一种UV清漆。The invention relates to a UV coating, in particular to a UV varnish.
背景技术 Background technique
UV涂料是利用紫外线照射产生化学作用而硬化的涂料，其主要成分是由感光树脂、活性稀释剂、光引发剂及助缉组成，该涂料以高能量的紫外光作为固化能源，由涂料中的光引发剂吸收紫外光能形成自由基，引发光敏树脂和活性稀释剂分子，进而发生连锁聚合反应，使涂膜达到固化。这种固化方式赋予UV涂料许多优点：固化及上光速度快、节能、常温固化、性能优越且绿色环保，其膜层光亮度高，干燥后膜面坚固耐热、能使底材的表面光亮、平滑且折光效果好。因此，鉴于上述优点，UV涂料已被广泛应用于化工、机械、电子、轻工及通讯等领域。然而，相对于传统油漆而言，UV清漆的易黄性是一个重要缺陷UV coating is a coating that is hardened by chemical action caused by ultraviolet radiation. Its main components are composed of photosensitive resin, reactive diluent, photoinitiator and assistant. The coating uses high-energy ultraviolet light as a curing energy source. The photoinitiator absorbs ultraviolet light energy to form free radicals, triggers photosensitive resin and reactive diluent molecules, and then undergoes chain polymerization reaction, so that the coating film is cured. This curing method gives UV coatings many advantages: fast curing and glazing speed, energy saving, room temperature curing, superior performance and environmental protection, the film has high brightness, the film surface is firm and heat-resistant after drying, and can make the surface of the substrate bright , smooth and good refraction effect. Therefore, in view of the above advantages, UV coatings have been widely used in the fields of chemical industry, machinery, electronics, light industry and communication. However, the yellowing tendency of UV varnishes is an important disadvantage compared to conventional paints
低黄变的UV清漆能使产品外观更显靓丽，因此，解决好UV体系的黄边问题意义非比寻常。Low-yellowing UV varnish can make the appearance of the product more beautiful. Therefore, it is of great significance to solve the problem of yellowing in the UV system.
