摘　　要：将西藏传统塑绘颜料分类为无机矿物颜料和有机植物颜料,选取雌黄和石绿作为无机矿物颜料的代表;花青和胭脂作为植物颜料的代表,以颜料颜色褪变色差ΔE与作用时间t的关系,探讨西藏塑绘颜料色调变化的影响因素;同时根据颜料的耐受性,在颜料中添加耐蚀耐光性颜料添加剂AX,对提高耐受性进行了试验。结果表明,酸性、碱性和氧化性等腐蚀性物质对塑绘颜料影响的规律是随着时间先快后缓;而无机矿物颜料和植物颜料受到的影响程度不同。太阳光、红光、紫外光3种光源对两类颜料的影响为:随照射时间的延长,色差值越来越大,显示太阳光<红光<紫外光,光照对有机颜料影响更大。AX能提高颜料的耐蚀性和耐光性,还可提高颜料色泽的稳定性。In the experimental process,realgar and malachite were selected as representatives of inorganic mineral pigments,while indigo and cochineal were chosen as representatives of plant pigments.The relationship between the color difference(ΔE)and the action time(t:day)of the pigment fading was used to explore the influencing factors of the color change of Tibetan sculpture-painting pigments.At the same time,according to the resistance of the pigment,the corrosion and light resistant pigment additive AX were added to the pigment to improve the resistance.The results show that the influence of corrosive substances such as acidity,alkalinity and oxidation on the pigments follows a rule of fast first and slow later,and the degree of influence on inorganic mineral pigments and plant pigments is different,with inorganic pigments being less affected.The influence of the three light sources on the two types of pigments is manifested as the color difference value becomes larger with the extension of the irradiation time.It displays that sunlight<red light<ultraviolet light,light has a greater impact on organic pigments.The AX in the experiment could improve the corrosion resistance and light resistance of the pigments,and improve the stability of the pigment color.
