Embodiment 1

[0014] Water-based fluorocarbon paint, water-based epoxy resin, additive [UV-531+Ti(OC) preferably used in the present invention 2 h 5 ) 4 complexes] are commercially available.

[0015] The preparation method of cultural relics colored drawing reinforcement material among the present invention is as follows:

[0016] (1) At room temperature, take 10g of water-based fluorocarbon paint with a solid content of 47% and 10g of water-based epoxy with a solid content of 20%, add 977g of pure water under ultrasonic stirring and mechanical stirring, the mechanical stirring speed is 200rpm, and the ultrasonic frequency The temperature is 40KHz, and the stirring time is 10min to form an emulsion.

[0017] (2) Put 3g of admixture into the above emulsion, and the admixture is UV-531+Ti(OC 2 h 5 ) 4 compound. Under the action of stirring, the ultraviolet light absorber is evenly dispersed in the emulsion to obtain the final reinforcement material for painted cultural relics.

Embodiment 2

[0019] The cultural relic painted reinforcement material prepared according to Example 1 is applied to the protection of ancient architectural painted paintings.

[0020] Protection method: put the reinforcing material into the watering can, spray evenly on the painted surface of the ancient building in a mist form, and can assist the external force to gently squeeze the painted surface, and then dry it naturally.

Embodiment 3

[0022] The cultural relic painted reinforcement material prepared according to Example 1 is applied to the protection of painted pottery unearthed at archaeological sites (humid environment).

[0023] Protection method: Put the reinforcement material into the watering can, spray it evenly on the surface of the wet painted pottery in the form of mist, and take out the painted pottery after it dries naturally.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to the preparation and application of a colored painting reinforcement material for cultural relics. Background technique [0002] Colored painting on cultural relics endows cultural relics with very important artistic, historical and archaeological information. Therefore, colored painting on the surface of cultural relics is especially precious. As the basic materials used to make cultural relics paintings have aged, resulting in the phenomenon of crisp powder, fading, warping and falling off in the paintings. [0003] Before the present invention, the reinforcement materials for color painting include inorganic reinforcement materials, organic reinforcement materials, and new reinforcement materials. Among them, the inorganic reinforcement materials include lime water, barium hydroxide alkaline earth silicate and fluorosilicate, etc., and the organi...
