Problems solved by technology

Long-term use of benzene is harmful to the body of the operator, and also affects the working environment of others. It has certain toxicity; excessive use of alcohol, banana water, and benzene in the operation method will also affect the color of the previous process and lose the level. In addition, although the color similar to the original cultural relic has been made in a few years: after five years, it will become darker, peeling, and aging, and cannot stand the test of time. This is a big taboo in the restoration of cultural relics; Under light and red candle lights, the color tends to become pale and white, so that others can see the damaged cultural relics at a glance, losing the principle and function of "repairing the old as the old", affecting the function and effect of the exhibition; The soluble pigments in base varnish and shellac are all inorganic pigments with coarse particles, so they are not suitable for coating the surface of copperware and making old porcelain glazes.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based coating for repairing ancient bronzes and ceramic devices. Background technique [0002] China has a splendid history of 5,000 years, and many ancient cultural relics have been left behind. Among them, bronze and ceramics are quite historical and common cultural relics. Bronze and ceramic cultural relics are mostly preserved in ancient tombs or cellars, buried underground for hundreds or even thousands of years. Due to the erosion of groundwater and the extrusion of deposits caused by stratum changes, many of them were damaged or deformed when they were unearthed, and some were even fragmented. Therefore, it is particularly important to restore the unearthed bronzes and ceramics as old as possible and to reproduce their scientific and artistic value. [0003] Before the present invention, to the restoration of bronze ware, pottery cultural relics, the one, welding or bonding broken cu...
