Description
Technical Field
The invention relates to glue solution and mixing solution for mineral pigment drawing of a holographic copying compound sleeve of an ancient mural, belonging to the technical field of mural copying.
Background
In the existing ancient mural painting copying, a concoction used for drawing the mineral color is an aqueous solution of gelatin, and the aqueous solution of gelatin is obtained by adding gelatin particles into water and then heating and melting the gelatin particles; most of the prior ancient murals are made of paper, the surface of the ancient murals is smooth, the water absorption is good, and the ancient murals have good effect when gelatin aqueous solution is applied to the paper base as a blending solution. However, when applying an aqueous gelatin solution as a tempering solution on a substrate material (i.e. the painting substrate disclosed in chinese patent CN 110802980 a) specific for holographic copying, a number of disadvantages arise. Specifically, as for a single aqueous solution of gelatin, the aqueous solution will solidify when the temperature is reduced, and the aqueous solution needs to be heated continuously to avoid solidification, but the adhesiveness of the aqueous solution is greatly reduced after multiple times of heating; when the gelatin aqueous solution is used as the blending liquid on the special substrate material for holographic copying, the surface of the substrate material has rough granularity, the mineral pigment is stone powder, and the weight and the particles are both large, so that the gelatin aqueous solution has low bonding degree and poor bonding effect; if the concentration of the gelatin aqueous solution is increased, the color effect of mineral substance color is influenced, and meanwhile, the gelatin aqueous solution is cracked after being completely dried, so that the use effect is poor; in addition, the main material of the gelatin is animal bones and skins, the gelatin is made into light yellow finished product liquid due to slightly low purity of the animal bones and the skins, when large-area drawing is carried out on the gelatin aqueous solution and the mineral pigment, a layer of light yellow film which is reflected on the original mineral color is formed after the gelatin aqueous solution is dried, and the whole color tone of the drawn product is slightly yellow; meanwhile, the faint yellow film is dry and crisp and has insufficient toughness, a finished product of the special base material for holographic copying has a curling function, and when a gelatin aqueous solution is used as a blending solution and the base material is drawn, local cracking can occur when the base material is curled.
Therefore, the technical problem to be solved in the field is to provide a mineral pigment drawing glue solution and a blending solution for holographic imitation complex set of ancient murals.
