Abstract:	全球暖化的現象不可忽視，如何減少空氣汙染已成為全世界的頭號目標。人為造成的空氣污染以揮發性有機化合物(Volatile Organic Compound, VOCs)最多，主要是人類在工業上使用了許多的有機溶劑，因此如何減少溶劑的使用，就可以降低VOCs排放。其中溶劑使用最多的就是表面塗裝業，表面塗裝是利用塗料塗在被塗物表面形成一層塗膜的方法，屬表面處理的方式，其應用最為廣泛，方法最簡單且最經濟的一種方法。本計畫提出高效能真空紫外光固化聚合物噴塗技術，主要是利用真空特性及無溶劑紫外光固化塗料(UV塗料)，來解決大氣噴塗長期以來對環境的污染及表面的不良，使用真空聚合物噴塗設備可減少VOCs的排放、空污處理費以及有機廢棄物處理費用都可以降低成本，此外更降低建廠所需的土地面積，計畫預計完成真空聚合物噴塗設備、真空聚合物噴塗專用UV塗料、塗料過濾系統、噴嘴霧化系統、高速攝影機觀測霧化系統以及噴塗流量控制系統等技術，第一年已完成建立真空聚合物噴塗系統與UV塗料測試，建立一台真空聚合物噴塗實驗機，使用三官能基與二官能基1:1的比例下，加上5%的光啟始劑，黏度在18cP，在真空噴塗設備下，以0.5GPH的燃油噴嘴在15kg氣壓下，完成噴塗成品，其亮澤度達到80%、硬度5H、附著性無脫落現象，無橘皮及氣泡等現象，第二年將持續優化真空聚合物噴塗設備以及完成UV塗料與噴塗霧化系統的最佳化，在真空環境10-1torr的情況下，可以噴塗黏度在15~65cP的UV塗料，噴塗在塑膠PC基材上塗膜表面平滑、無氣泡及氣孔、硬度≧5H、附著性0、噴塗速率大於2m/s，在室溫下浸泡5 % H2SO4及NaOH連續48小時，耐酸鹼測試無脱膜及膜裂現象。 ;The phenomenon of global warming can’t be ignored, how to reduce air pollution has become the number one goal in the world. The most of anthropogenic air pollution caused by volatile organic compounds (VOCs), because the industrial use of a lot of organic solvents. So how to reduce the use of solvents, it will reduce the VOCs. One of the most widely used solvent is the surface coating industry, the surface coating is the use of paint on the surface to be coated coating layers. It is a surface treatment and the most widely used, the simplest and most economical method.This project proposes the high performance vacuum polymer spray and UV curing Technology, is using vacuum characteristics and solvent-free UV-curing coating (UV coating) to solve the atmospheric spray method caused long-term environmental pollution and surface defects. Vacuum polymer spray equipment can reduce VOCs, air pollution treatment costs and organic waste disposal costs, in addition to reducing the land required for plant construction. The project is expected to complete the vacuum polymer spray equipment, UV coating using in vacuum polymer spray, filter system, nozzle system, observation spray system by high-speed camera and spray flow control system technology. You can spray the UV coating (viscosity of 15 ~ 65cP) in the plastic PC substrate in the 10-1torr vacuum environment. The coating surface smooth, no bubbles and pores, hardness ≧ 5H, adhesion 0, spraying rate is greater than 2m / s, and no stripping and crack at room temperature soaking 5% H2SO4 and NaOH for 48 hours.
