Preparation and application of cultural-relic color-painting reinforcing material

The present invention relates to preparation and application of a cultural-relic color-painting reinforcing material. The preparation comprises the following steps: pouring a waterborne fluorocarbon coating with a solid content of 47% and waterborne epoxy resin with the solid content of 20% into pure water in proportion, carrying out constant stirring, and then adding an additive for reaction so as to obtain an ultraviolet-light-absorbing protective glue solution which forms an emulsion. The cultural-relic color-painting reinforcing material of the invention overcomes the defects that the values of the cultural relics are influenced and the like because single usage of conventional color-painting reinforcing materials like an inorganic reinforcing material, an organic reinforcing material and a novel reinforcing material influences the appearance, strength, life and the like of color paintings. The cultural-relic color-painting reinforcing material prepared in the invention has the properties of dust prevention performance, water resistance, acid resistance, strong anti-aging ability, strong adhesive force and appropriate hardness and can reinforce and protect fragile, crisp and loose cultural-relic color-painting layers, so various mechanical strengths and mechanical properties of the color-painting layer bodies are effectively improved.
