一分鐘帶你了解光固化涂料

更新日期： 2021-5-17 |
光固化涂料主要指在紫外光照射下迅速交聯(lián)固化的一類新型涂料，通常指從液體樹(shù)脂變成固態(tài)干膜的過(guò)程。因其高效涂裝固化、低能耗和環(huán)境友好特征，已為世界涂料行業(yè)認(rèn)可，近年來(lái)發(fā)展迅速。
UV cured coating mainly refers to a new type of coating which is quickly cross-linked and cured under ultraviolet (UV) irradiation. It usually refers to the process of changing from a liquid resin to a solid dry film. Because of its high-efficiency curing process, low energy consumption and environment-friendly characteristic, UV cured coating has been globally recognized by the coating industry. It has developed rapidly in recent years.

歷史/History
★20世紀(jì)60年代由Bayer公司成功商業(yè)化光固化涂料。
UV cured coating was put into commercial production by Bayer in the 1960s.
★2000年全球僅用于家具等木器涂裝的光固化涂料已超過(guò)2.2萬(wàn)噸。
Over 22,000 tons UV cured coating was globally used on wood only for furniture in 2000.
★2010年用于包裝領(lǐng)域的光固化涂料增至5.3萬(wàn)噸。
Up to 53,000 tons UV cured coatings was used in packaging industry in 2010.
★至今大量應(yīng)用于紙張、塑料、金屬、玻璃、陶瓷等多種基材。
Till date, a huge number of UV cured coatings have been applied on paper, plastic, metal, glass, ceramic and many other substrates.

波長(zhǎng)/Wavelength
在一般光化學(xué)研究和光固化應(yīng)用中有實(shí)際意義的是中紫外和近紫外區(qū)的紫外光，通常又劃分為以下三個(gè)波段: UV A, UV B 和 UV C。光固化體系常用UV A (315~400nm) 和 UV B (280~315nm)，集成電路制作的光刻技術(shù)常用UV C (200~280nm)。
In general photochemical research and UV curing applications, UV light is usually divided into the following three bands during the mid-ultraviolet and near-ultraviolet regions, including UV A, UV B and UV C. Among them, UV A (315~400nm) and UV B (280~315nm) are commonly used in UV cure system. UV C (200~280nm) is usually applied in lithography technology for integrated circuit production.

Used for photolithography in photosensitive materials.三維激光成型/3D laser forming
20世紀(jì)80年代末發(fā)展起來(lái)的快速成型技術(shù)，利用激光引發(fā)感光樹(shù)脂的聚合，要求感光樹(shù)脂低粘度、高固化速度、低收縮、低溶脹、層間黏附相容性好、光敏感度高等。
The rapid prototyping technology was developed in the late 1980s. It uses laser to initiate the polymerization of photosensitive resins. The photosensitive resin must possess low viscosity, high curing speed, low shrinkage, low swelling, good interlayer adhesion compatibility and high photosensitivity.
