树脂对风化汉白玉文物的保护作用

Protective Effect of Resin on Efflorescent White Marble Cultural Relics

通过检测耐酸碱盐腐蚀性、耐酸度、透气性、憎水性、耐光老化性等性能,对目前应用于石质文物保护效果较好的丙烯酸类、氟碳树脂类和有机硅类三种树脂材料的保护性能进行评定。研究发现,三种树脂材料都对汉白玉文物有较好的保护性能,但有机硅树脂的透气性和憎水性能等要明显优于丙烯酸类和氟碳树脂类,更加适合于室外风化汉白玉文物的保护。

The protective effect of three resin materials including,acrylate,fluorocarbon and silicone on white marble was evaluated by property tests of the anti-corrosion capability against acid,alkali and salt,the acid degree,the air permeability,the hydrophobicity and the light resistance.The results indicated that all three coatings had good protection effect.The silicone coating had a better capability of air permeability and hydrophobicity than the other two,and is suggested to be the conservation material for efflorescent white marble cultural relics.
