佛光寺彩画加固保护材料的选择实验研究

Experimental research on the selection of materials for reinforcement and protection of the architectural painting of the Foguang Temple

针对佛光寺无地仗彩画层所出现的颜料脱落、颜料褪变色、裂隙等突出病害,本研究利用正交实验对鱼胶和白芨胶两种传统保护材料进行了复配,得到适宜无地仗彩画加固保护的优选配方:以质量分数为3%的鱼胶复配以0.1%的白芨胶作为有效加固成分,再配以质量分数为0.5%的防霉剂(PTA)、0.1%的紫外吸收剂(BP-4)以及0.1%的抗静电剂。所得复配材料具有优良的加固性能及耐老化性能,可为佛光寺及其他地区无地仗彩画加固保护材料的选择提供参考。

The study addresses the urgent need to protect architectural paintings at the Foguang Temple. These un -grounded paintings face much damage, including the peeling off of pigments, fading and cracking. Orthogonal experiments were done on entailing compounding of two traditional protection materials： the gum of Bletilla striata （Thunb） Rchb. f. and fish collagen. These experiments show that the best formula for strengthening and protecting architectural paintings with no plaster layer is （weight percentile） ： 3% fish collagen and 0. 1% gum of Bletilla striata, as the effective reinforcement ingredients, coupled with 0.5 % fungicide （ PTA）, 0.1% of UV absorbers （ BP - 4） and 0.1% antistatic agent. This formulation shows excellent performance in terms of reinforcing, antifungal and anti - UV aging properties. This is a good choice for the reinforcement and protection of the architectural paintings at the Foguang Temple and other similar sites.
