【摘要】：我國是漆樹的原產(chǎn)國,我們的祖先在新石器時代就開始收割、使用生漆。在漫長的發(fā)展過程中,先民不斷提高漆器制作技術(shù),創(chuàng)造了光輝燦爛的漆文化。安徽省六安市白鷺洲戰(zhàn)國墓M585出土了一批漆甲片,整體保存較好,數(shù)量較多,制作精美,具有極高的歷史價值、科學(xué)價值和藝術(shù)價值,為研究這一時期軍事、技術(shù)、文化提供了寶貴的實物資料,并為墓主人身份判定提供一定的依據(jù)。但是漆甲片存在脆化、裂隙、變形等病害,需要對其進行保護修復(fù),而漆膜的回軟技術(shù)是保護的關(guān)鍵部分。前人的研究中,對漆膜回軟藥品濃度、回軟溫度、回軟時間等條件的選擇主要是依靠經(jīng)驗,而未有一個科學(xué)的篩選。特別是在漆膜回軟機理方面,研究者只做了漆膜回軟前后結(jié)構(gòu)的對比研究,而未對其回軟過程進行具體分析。本論文主要進行以下工作:首先分析甲片的保存狀況、存在病害;其次,通過超景深顯微觀察、掃描電鏡觀察、紅外光譜等手段對出土漆甲的制作材料、工藝進行分析,為漆甲的保護修復(fù)工作、回軟機理研究提供依據(jù);再次,通過實驗對漆甲回軟條件進行科學(xué)篩選,得到回軟漆甲的最適條件;最后通過掃描電鏡觀察、紅外光譜分析、熱重等微觀分析手段對不同回軟時間的漆甲進行檢測,探討漆膜的軟化機理。通過以上研究篩選出白鷺洲戰(zhàn)國墓出土漆甲的最佳回軟條件,即:回軟試劑為70%的1,2-丙二醇、回軟溫度100℃、回軟時間24h。同時得到該條件下漆膜回軟的微觀機理:漆膜在回軟過程中,發(fā)生物理溶脹和化學(xué)溶脹作用,發(fā)生物理溶脹的過程中,1,2-丙二醇充填到漆膜大分子間隙中,增大了漆膜大分子間的距離,降低了漆膜分子間作用力和氫鍵作用力,造成漆膜內(nèi)部應(yīng)力下降;而化學(xué)溶脹的過程中,漆膜內(nèi)部分子鏈發(fā)生斷裂,降低漆膜結(jié)構(gòu)的整體性,使漆膜內(nèi)部應(yīng)力下降,從而達到軟化漆膜的效果。
[Abstract]:China is the country of origin of lacquer trees. Our ancestors began harvesting and using raw lacquer in the Neolithic Age. It has created a splendid lacquer culture. A number of lacquer nail pieces were unearthed from the tomb M585 of Bai Luzhou warring States Tomb in Lu'an City, Anhui Province. The overall preservation is good, the quantity is large, the production is exquisite, and it has extremely high historical value, scientific value and artistic value. In order to study the military, technology and culture of this period, it provides valuable material data and provides some basis for the identification of the owner of the tomb. However, the lacquer nail pieces have some diseases, such as embrittlement, fissure, deformation and so on, which need to be protected and repaired. In previous studies, the selection of the concentration, temperature and time of the soft film is mainly based on experience. But there is no scientific screening. Especially in the mechanism of film softening, researchers have only done a comparative study of the structure of the film before and after softening. The main work of this paper is as follows: firstly, the preservation status of A piece is analyzed, there are diseases; secondly, by means of the observation of depth of field, scanning electron microscope, Infrared spectroscopy and other means of unearthed lacquer materials, technology analysis, for the protection of the restoration of paint, soft mechanism of research; thirdly, through experiments on the soft conditions of the scientific screening, Finally, the optimum conditions were obtained by means of scanning electron microscopy, infrared spectroscopy, thermogravimetry and other micro-analysis methods to detect the varnish with different softening time. The softening mechanism of paint film was discussed. Through the above studies, the optimum soft conditions for the unearthed lacquer armor unearthed in the warring States Tomb of Bailizhou were selected, that is, the softening reagent was 1 ~ (2) -propanediol (70%), and the softening temperature was 100 鈩，
