    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固化的一類新型涂料,通常指從液體樹脂變成固態干膜的過程。因其高效涂裝固化、低能耗和環境友好特征,已為世界涂料行業認可,近年來發展迅速。

    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60年代由Bayer公司成功商業化光固化涂料。

    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2.2萬噸。

    Over 22,000 tons UV cured coating was globally used on wood only for furniture in 2000. 



    2010年用于包裝領域的光固化涂料增至5.3萬噸。

    Up to 53,000 tons UV cured coatings was used in packaging industry in 2010.



    至今大量應用于紙張、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/Wavelength





    在一般光化學研究和光固化應用中有實際意義的是中紫外和近紫外區的紫外光,通常又劃分為以下三個波段: 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.

    應用/Application



    1

    光固化涂料/UV cured coating

    應用于竹木地板、塑料、紙品、金屬、光纖、皮革、陶瓷、石材等。
    Used in wood flooring, plastic, paper, metal, optical fiber, leather, ceramic, stone, etc.

    2

    光固化油墨/UV cured ink

    應用于包裝裝潢、印刷、電子 (抗蝕油墨、阻焊油墨、標記油墨) 等。

    Used in packaging, printing, electronics (anti-corrosion ink, solder mask ink, marking ink), etc.

    3

    光固化膠黏劑/UV cured adhesive

    分為結構膠、密封膠、層合膠、壓敏膠等。應用于光學鏡頭裝配、水晶工藝品、微電子裝配、金屬和塑料支架接合、一次性醫療器械、液晶顯示屏裝配、玻璃器皿粘接等。

    Divided into structural adhesives, sealants, laminating adhesives, pressure-sensitive adhesives, etc. Used in optical lens assembly, crystal crafts, microelectronic assembly, metal and plastic bracket bonding, disposable medical equipment, LCD display assembly, glassware bonding, etc.

    光刻膠/Photoresist

    用于光刻術的感光材料。

    Used for photolithography in photosensitive materials.

    5

    三維激光成型/3D laser forming

    20世紀80年代末發展起來的快速成型技術,利用激光引發感光樹脂的聚合,要求感光樹脂低粘度、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.
