    中車高端薄膜材料搶占國際市場

    時間:2019-03-29 11:55:16 來源:人民鐵道網 作者:王盈 姜楊敏
    \

      人民鐵道網訊(通訊員 王盈 姜楊敏)日前,某著名手機產商推出的一款旗艦手機中的高導熱石墨片中,所使用的高性能聚酰亞胺(PI)薄膜,70%來自中車時代新材的PI薄膜生產線,這也是目前國內唯一一條實現批量制造的化學亞胺法制膜生產線。
     
      PI薄膜又被稱為"黃金薄膜",主要用于軌道交通、電子信息、航空航天、柔性顯示、新能源、軍工等高科技領域。將高性能PI薄膜通過高溫碳化石墨化后,可以得到導熱率數倍于銅的導熱石墨片,這是目前電子產品解決散熱問題的最佳方案。憑借先進的化學亞胺化技術,國外PI膜企業長期壟斷市場,并對我國限量供貨,極大制約了國內相關戰略產業發展。
     
      "伴隨著5G技術和超大規模集成電路制造與封裝等高新技術的發展,我國對高性能聚酰亞胺薄膜的需求日益增加,市場潛力巨大。"中車時代新材PI薄膜項目負責人張步峰博士介紹,上世紀90年代后期,我國對這種薄膜的年需求量為500噸,到了2010年就已經超過2800噸,且每年以25%的速度增長。
     
      中車時代新材于2011年啟動PI膜項目研發,先后攻克了配方技術、裝備技術及制膜工藝難題,于2017年底,建成了國內首條化學亞胺法PI薄膜生產線,成功實現了高端PI薄膜批量制造,年生產能力達到500噸,成為全球第4家、中國首家具備批量產能的供應商。經過批量試用,產品品質達到了美國、日本同類產品水平,成功替代進口產品。批量投產以來,國產高端PI薄膜已成功應用于華為、VIVO等手機品牌。
     
      除用于電子產品外,PI薄膜憑借其耐高溫、電絕緣的特性,在軌道交通、航空航天等電機絕緣和防護系統中也發揮著不可替代的作用。目前,中車時代新材的PI薄膜已啟動在軌道車輛電機絕緣系統上的應用導入工作,有望在今年實現裝車運行。
     
      "為了滿足市場需要,目前我們正在進行生產線的二期工程建設,項目建成后,預計年產能將達2000噸,以滿足國內外高尖端技術產業需求。"張步峰表示。
