【摘要】:因?yàn)楣鈱W(xué)塑料新的應(yīng)用不斷出現(xiàn),所以對(duì)膜層的要求就更加嚴(yán)格。光學(xué)塑料表面硬度差,在溫度升高后容易發(fā)生膜裂的現(xiàn)象一直制約著光學(xué)塑料制品的進(jìn)一步發(fā)展。本課題主要解決現(xiàn)有光學(xué)塑料鏡片表面易劃傷、高溫時(shí)容易發(fā)生膜裂的問(wèn)題。選取機(jī)械性能穩(wěn)定的Ti3O5、SiO2和LSA作為高、低折射率材料,依據(jù)光學(xué)薄膜理論,借助TFCalc軟件設(shè)計(jì)膜系,通過(guò)電子束加熱蒸發(fā)和離子源輔助沉積薄膜,在膜系的最外層用電阻加熱法鍍制防水膜。通過(guò)選擇新材料LSA作為連接層,增強(qiáng)了塑料鏡片與膜層的附著力,解決了膜層與塑料鏡片膨脹系數(shù)不匹配的問(wèn)題,提高了塑料鏡片的抗溫能力。通過(guò)不斷優(yōu)化工藝參數(shù),在光學(xué)塑料基底上得到400-700nm反射率R=0.9%的減反膜。在經(jīng)過(guò)耐磨測(cè)試后,塑料表面硬度明顯提高,摩擦后測(cè)得憎水角到大于110°,在高溫125℃加熱100min后,沒(méi)有發(fā)生膜裂現(xiàn)象。研究塑料鏡片的鍍膜技術(shù),對(duì)塑料光學(xué)元件的應(yīng)用和發(fā)展具有一定的促進(jìn)作用。
[Abstract]:As new applications of optical plastics continue to emerge, the requirements for film coating are more stringent. The surface hardness of optical plastics is poor, and the film cracking is easy to occur after the increase of temperature, which has been restricting the further development of optical plastic products. This paper mainly solves the problem that the surface of the optical plastic lens is easily scratched and the film crack is easy to occur at high temperature. Ti3O5SiO2 and LSA, which have stable mechanical properties, are selected as high and low refractive index materials. According to the theory of optical thin film, the film system is designed by TFCalc software, and the film is deposited by electron beam heating evaporation and ion source assisted deposition. A waterproof film is deposited on the outermost layer of the film by resistance heating. By selecting the new material LSA as the connecting layer, the adhesion between the plastic lens and the film is enhanced, the problem of the mismatch of the expansion coefficient between the film and the plastic lens is solved, and the temperature resistance of the plastic lens is improved. The antireflection film with 400-700nm reflectivity of 0.9% was obtained on the optical plastic substrate by optimizing the process parameters. After wear resistance test, the hardness of plastic surface was obviously improved, and the hydrophobic angle was measured to be more than 110 擄after friction. After heating 100min at high temperature of 125 鈩,
