Stone colored drawing reinforcing agent

Abstract

Provided is a stone colored drawing reinforcing agent. The reinforcing agent is composed of 1.6wt.%-2.0wt.% of Paraloid B72, 1.0wt.%-1.4wt.% of Primal SF-016, 95.7wt.%-97.2wt.% of ethyl acetate, 0.09wt.%-0.4wt.% of UV-531 and 0.1wt.%-0.5wt.% of the light stabilizer 770. The stone colored drawing reinforcing agent has advantages of water resistance, acid resistance, alkali resistance, strong ageing resistance, strong adhesion and high hardness, and can reinforce and protect colored drawing layers, which are in slight crisping and easy to fall off, of stone colored drawings. The mechanical strength and mechanical properties of the colored drawing layer bodies are raised effectively. The reinforcing agent is beneficial for long-term preservation of cultural relics and the processed colored drawing layers can keep pristine original appearances and has little color change. The reinforcing agent has simple implementation technology and remarkable reinforcement effects, and can be used for reinforcement of crisping stone colored drawings.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a reinforcing and protecting agent capable of reinforcing crisp powder and easy-to-fall stone colored paintings. Background technique [0002] Stone painted cultural relics are very precious. Colored painting endows stone cultural relics with very important artistic, historical and archaeological information. Colored paintings on stone carvings are easy to powder, fall off, and fade. The reinforcement materials for stone cultural relics recorded in relevant literature include inorganic reinforcement materials, organic reinforcement materials, and new reinforcement materials. Among them, the inorganic reinforcement materials include lime water, barium hydroxide alkaline earth silicate and fluorosilicate, etc., and the organic reinforcement materials include silicate, siloxane, epoxy resin, acrylic resin, silicone resin, organic fluorine materials and...
