Abstract

The invention discloses a fraxinus mandshurica wood surface antique finishing process for an antique building. The process comprises the steps: weighing the following raw materials in parts by weight:35-55 parts of an open paint, 50-70 parts of a modified liquid, 15-20 parts of gelatin, 2-3 parts of citric acid, 2.5-4.0 parts of sodium acetate, 15-20 parts of triethanolamine, 2.0-2.2 parts of calcium chloride and 200-250 parts of deionized water. When the prepared open paint is sprayed on the surface of fraxinus mandshurica; the coating has excellent adhesive force and gloss retention performance, and high gloss, and a film can be formed once; therefore, the coating can be better compounded with fraxinus mandshurica wood, the spraying requirements under various conditions can be met, andthe technical problems that existing nitro-lacquer is high in viscosity, only used for spraying and incapable of forming a film at a time, when the nitro-lacquer is sprayed to the surface of fraxinusmandshurica wood, the glossiness is low, the film cannot be formed at a time, and the bonding capacity with the fraxinus mandshurica wood is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of wood products, in particular to a process for making old ash wood surfaces for antique buildings. Background technique [0002] At present, there are still the following problems when the surface of wood products is aged: the process is complicated, the antique effect is not good enough, the quality of wood is high, and the commonly used wood is few; Ash is mainly produced in Northeast, North China and other places. Yellowish-white (sapwood) or brownish-yellow (heartwood). The annual rings are obvious but uneven, the wood structure is thick, the grain is straight, the pattern is straight, dull, and the hardness is small. Ash has the characteristics of elasticity, good toughness, wear resistance and moisture resistance. But it is difficult to dry and easy to warp. The processing performance is good, but tearing should be prevented, but the ash wood tends to turn yellow when it is ol...
