Problems solved by technology

[0006] On the other hand, due to the poor film-forming properties of existing bone resource protection agents, they cannot maintain good ductility while maintaining hardness. During the long-term protection process, cracks and discoloration may occur due to oxidation or changes in environmental humidity, resulting in bone Secondary damage occurs during protection
This also reflects that the filling performance of the existing bone resource protection agent is not good, and the reinforcement effect cannot meet the actual needs

Abstract

The invention provides an ancient skeleton resource protection agent and belongs to the field of protection of ancient skeleton resources. The ancient skeleton resource protection agent is prepared from 10 to 25 parts of a binding agent, 10 to 25 parts of propylene glycol, 0.01 to 0.3 part of an antioxidase simulant, 0.01 to 0.05 part of a plant extract antioxidant, 0.002 to 0.005 part of a preservative, 0.1 to 0.3 part of lysozyme and the balance of water; the binding agent is selected from mixed type water-soluble protein. According to the ancient skeleton resource protection agent, the specific binding agent and the propylene glycol are used as base materials and the antioxidase simulant, the plant extract antioxidant, the preservative and the lysozyme which have specific types are selected and are mixed with the water to prepare a product; different substance components and content thereof are matched and all the components have a mutual cooperative enhancement effect; after the ancient skeleton resource protection agent is sprayed on an ancient skeleton, the ancient skeleton resource protection agent has very good film-forming performance, reversibility, protectiveness, anti-oxidization and antibacterial capabilities and filling performance; the film-forming time can be reduced and the reinforcing effect is further strengthened; and the ancient skeleton resource protectionagent has no injuries to human bodies and ensures the safety of operators and visitors.

Description

technical field [0001] The invention relates to the field of protection of ancient bone resources, in particular to an agent for protection of ancient bone resources. Background technique [0002] At present, there are many kinds of protective agents used for ancient bone resources, mainly resin protective agents, including: natural resin and nitro varnish, dispersion system of acrylic colloid, acrylic emulsion products, polyvinyl acetate, polyvinyl alcohol Butyraldehyde, acrylic resin, trimethyl resin (copolymer of methyl methacrylate-butyl methacrylate-methacrylic acid), in addition to polyethylene glycol (PEG) protective agent, but as people With the use, their shortcomings are gradually exposed, and their common shortcomings are poor reversibility and high toxicity. [0003] Natural resin and nitro varnish have poor reinforcement and have a certain color, which is not conducive to the protection and ornamental effect of the remains, and is not used at present; the dispe...
