【摘要】：目前对古代陶胎的研究多集中在加固材料的筛选及其保护效果评估上,普遍缺乏深入的保护机理的研究,尤其保护材料对陶胎盐风化的影响及其机理研究在国内更是罕见。因此,本实验选用TEOS(正硅酸乙酯)、Paraloid B72和WD10对模拟古代秦俑陶胎进行了加固和防盐风化保护研究。重点观察了不同材料处理后陶胎样品表面盐结晶的形貌,并对其形成机理进行了探讨。最后对Paraloid B72在耐盐实验中出现的保护性破坏现象给予关注。结果显示,TEOS处理后陶胎的抗压强度得到提高,但对陶胎的耐盐性能没有改善;Paraloid B72处理后,陶胎颜色加深,耐盐实验中处理陶胎出现了严重的盐风化。WD10处理后陶胎的耐盐性能显著增强。对盐结晶的微观形貌研究初步揭示,保护材料能够对陶胎表面进行改性,不同的憎水性和渗透性会显著影响盐结晶的微观形貌,进而会带来不同类型的盐风化。本研究结果启示文物保护工作者必须深入了解各种保护材料的优缺点,根据被保护文物的具体实际需求,慎重开发和选择保护材料,以避免保护性破坏现象的出现。
[Abstract]:At present, the study of ancient pottery tire more concentrated in the selection of reinforcement material and its protection effect, lack of protection mechanism of in-depth research, especially the protection of material influence on the pottery body of salt weathering and its mechanism in the country is rare. Therefore, this experiment selected TEOS (TEOS), Paraloid B72 and WD10 the reinforcement and Research on anti salt weathering protection for simulating ancient terracotta pottery. The morphology of different tire materials treated pottery tire sample surface salt crystallization, and its formation mechanism was discussed. Finally, give attention to Paraloid B72 damage phenomena in protection of salt tolerance in experiments. The results showed that the compressive strength the strength of pottery tire improved after TEOS treatment, but the pottery tire anti salt performance did not improve after treatment; Paraloid B72, Tao fetal color deepens, salt tolerance in experimental treatment appeared fetal Tao salt weathering serious.WD10 Salt resistance after Tao births increased significantly. The study of the micro morphology of salt crystallization revealed, protective material to pottery tire surface modification, morphology of different hydrophobicity and permeability will significantly affect salt crystallization, which will bring about different types of salt weathering. The research results of cultural enlightenment the protection of workers must have a thorough understanding of the advantages and disadvantages of all kinds of protection materials, according to the actual needs to be carefully protect cultural relics, development and selection of protective material, to avoid the destruction of the protective phenomenon.

【正文快照】： 0引言陶器包括素陶、彩陶、彩绘陶,是中华民族宝贵的历史文化遗产之一[1]。陶器的烧结温度一般在800~1000℃之间,烧成后器物的孔隙率较高,结构不致密,强度较低,吸水性强,造成陶器先天不足,自毁率极高。陶器胎体病害的主要表现有:酥粉,即陶胎呈粉状或者颗粒状松散的现象,这是陶
