In china, many ancient towns and most of the major cities still retain some ancient buildings. However, in the present of the great interest of civil engineering, we want to see and protect ancient buildings and their cultural traits; the ancient architectural culture is preserved in the world, and the ancient cultural heritage generates modern value. In the prior art, ancient buildings are mostly made of wood materials, the damages of the wood materials, such as corrosion, worm damage and the like, which often go through the month are difficult to repair, and the existing material repair is mostly raw lacquer;
raw lacquer (Raw laequer), also known as national lacquer, earth lacquer and old lacquer, has a decorative style of simple and modesty, mild and elegant, firm and corrosion-resistant, ecological and energy-saving, is widely applied in the paint engineering of antique buildings, has a history of over 2500 years and leaves a plurality of famous buildings from old to now. However, the natural raw lacquer is harvested from lacquer trees, the quality and performance are very different and uneven due to the influence of factors such as varieties, soil, climate and the like, and the construction and decoration requirements can be met only by processing the natural raw lacquer by adopting a certain technical means. The prior raw paint for antique buildings has the defects of high selectivity to base materials, high requirement on film forming conditions of the paint, poor adhesive force, weather resistance, alkali resistance, wear resistance, flame retardance and the like, but also has certain problems:
in the process of using and drying the coating, the film forming speed of the coating is low, the process of outward migration and drying of moisture in the use of the coating is improved, the coating curing period is prolonged, and the surface of the coating is irregularly sunken, so that the coatings in different areas show different effects;
the existing coating has poor sagging resistance and cannot be uniformly attached to the surface of a building, so that the surface of a formed building is not smooth and clean, the defects of air holes, sand adhesion and insufficient mold filling are easy to occur, and the building caused by the coating is not smooth and clean, so that the actual repair requirement cannot be well met.
