Abstract
The invention provides a silk protein reinforcing method for fragile silk, comprising the steps as follows: A) the fragile silk with the weight ratio of 1:30-200 is put in a silk protein solution with the weight percentage of 0.1-5% and dipped for 1min to 2h at the temperature of 20-35 DEG C and then taken out and naturally dried; B) the fragile silk is put in ethylene glycol diglycidyl ether solution with the weight percentage of 0.001-10%, dipped for 1min to 2h at the temperature of 20-35 DEG C and then taken out; C) after the treatment, the fragile silk is solidified for 24h to 2h at the temperature of 20-60 DEG C; and D) after natural drying, the silk reinforced by the silk protein molecular is obtained. The method has the advantages of simple method, convenient operation, not affecting the appearance of the silk relic, partly recovering the true luster of the relic, having outstanding advantages on high-temperature ageing resistance, and the like.
Description
Technical field
What the present invention relates to is a kind of fibroin reinforcement process of fragile silk, belongs to the technical field of historical relic's protection.
Background technology
Silk is the symbol of Chinese mature culture.China all has a large amount of silk historical relics to be unearthed every year, these silk historical relics have been crossed over 6,000 years up and down, having very high history, archaeology and scientific value, is the important component part of China's historical relic, is research China successive dynasties politics, economy, art, the very important data in kind of scientific and technological aspects.Because silk protein is a kind of bioabsorbable polymer material, is easy to be subjected to multiple factor affecting and damaged.Different factors such as extraneous water, heat, oxygen, illumination, acid, alkali, microorganism all can cause the fracture of silk protein generation sex change and macromolecular chain, make silk fiber tender, fracture easily, and mechanical strength obviously descends.
Both at home and abroad the past to the reinforcement protection of silk historical relic mainly contain the braiding method for strengthening, mount the holder method, coating method, silk net reinforcing method, resin method for strengthening, adhesive method for strengthening, group draw synthetic fibre vacuum coating method, grafting copolymerization process etc.
On the Chinese patent communique, disclose that propose by the Hubei Provincial Museum a, number of patent application and be 200410012737 application for a patent for invention, it relates to a kind of " the microorganism reinforcement means of no intensity silk ", this method is that carbohydrate and organic acid are converted into cellulose with acetobacter, thereby reaches the purpose of reinforcing no intensity silk.Also disclosing one on the Chinese patent communique is 200810063254.2 application for a patent for invention by common that propose, the number of patent application of Institutes Of Technology Of Zhejiang, China Silk Museum, it relates to a kind of " preparation method of fibroin strengthening agent ", this method utilization and historical relic identical materials-fibroin prepare strengthening agent, and this strengthening agent is made of fibroin solution and auxiliary agent glutaraldehyde solution two parts.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of silk historical relic that is used for, the fibroin reinforcement process of more safe and effective fragile silk.The objective of the invention is to finish by following technical solution, it adopts following steps:
A) with fragile silk by weight 1: 30～200 fibroin solution that place 0.1%～5% weight percent concentration, take out after 1 minute to 2 hours at 20～35 ℃ of dippings, allow its air dry;
B) again fragile silk is put into the ethylene glycol diglycidylether aqueous solution of 0.001～10% weight percent concentration, taken out after 1 minute to 2 hours at 20～35 ℃ of dippings;
C) will under 20～60 ℃ condition, solidify 24 hours to 2 hours through the fragile silk after the above processing;
D) dry naturally after, obtain the silk of reinforcing through the fibroin molecule.
Fibroin solution of the present invention adopts silk fibroin protein solution.
The present invention is under the help of auxiliary agent ethylene glycol diglycidylether, utilizes fibroin to reinforce fragile silk, is used for the protection of silk historical relic; Through this method consolidation process at fragile silk, not only intensity increases considerably, aspect effects such as the silk color and luster after the reinforcing are also better, the result of anti-aging test also shows, the present invention has outstanding superiority high temperature resistant aspect aging.Compared with the prior art, it has following outstanding advantage: 1) method is simple, and is easy to operate; 2) do not influence the outward appearance of silk historical relic, and can partly recover the silky luster of historical relic; 3) outstanding superiority is arranged high temperature resistant aspect aging.
