Abstract

The invention discloses a repairing material for a base layer of oil colored paintings of ancient architecture, which comprises an acrylic acid-2-ethylhexyl ester, a vinyl acetate, a methyl methacrylate, an acrylic acid, an N-hydroxymethyl acrylamide, an emulsifying agent, a neutralizing agent, a defoaming agent, a rheological agent and an initiating agent. The preparation technology comprises the following steps of: preparing a polyacrylate emulsion by using free radical emulsion polymerization, and adding the neutralizing agent, the deforming agent and the rheological agent in the polyacrylate emulsion to obtain an emulsion binder. The emulsion binder prepared by the invention has no granular condensation products, good mechanical stability, freeze thaw stability and interface adhesion force, can be coated and injected, is free from ash removal and reversible at a high temperature and is applicable to the binding materials for repairing the base layer of the oil colored paintings of the ancient architecture.

Description

technical field [0001] The invention relates to a repairing material for the floor covering of oil-decorated paintings of ancient buildings and its preparation technology. The repairing material is an emulsion adhesive, which can be used as a bonding material for repairing the floor coverings of oil-decorated paintings of ancient buildings, and belongs to the technical field of cultural relics protection and restoration . technical background [0002] The floor layer of ancient architectural oil decoration paintings is located between the paint layer and the wood base layer, and the general thickness is about 4-6mm. After hundreds of years or even thousands of years of history, due to comprehensive reasons such as the environment (temperature, humidity, light, wind, sand, etc.), organisms (microorganisms, insects, etc.), attachment substrates, and production materials, ground wars generally occur. Problems such as bones, bulges and cracks in the ground warp seriously damage...
