【摘要】：糟朽皮革文物保護(hù)的重要問題之一是選擇合適的加固材料。以動物皮為原料,制備與皮革具有同源性的皮漿作為糟朽皮革的加固材料。用戊二醛、單寧對皮漿膜進(jìn)行改性,提高皮漿膜的熱穩(wěn)定性。以改性皮漿膜的抗張強度和斷裂伸長率為主要指標(biāo)來評估皮漿作為加固材料的可行性。通過加固人工老化皮革試驗,對比分析了樣品加固前后的機(jī)械強度、纖維形態(tài)。結(jié)果表明:處理劑戊二醛、單寧酸溶液的首選質(zhì)量分?jǐn)?shù)分別為3%、12%。皮漿膜的抗張強度可達(dá)5N/mm~2以上,斷裂伸長率可達(dá)90%以上。皮漿能補充和改善糟朽皮革中流失和變性的膠原蛋白,有效提高其物理性能。本研究為糟朽皮革文物的加固保護(hù)提供了新思路。
[Abstract]:One of the important problems in the protection of leathery relics is the selection of suitable reinforcement materials. Using animal skin as raw material, leather pulp with homology with leather was prepared as reinforcement material for leathery leather. Glutaraldehyde and tannin were used to improve the thermal stability of the pulp film. Based on the tensile strength and elongation at break of the modified skin size film, the feasibility of the pulp as the reinforcement material was evaluated. The mechanical strength and fiber morphology of the samples before and after reinforcement were compared and analyzed through the experiments of strengthening artificial aged leather. The results showed that the preferred mass fraction of glutaraldehyde and tannic acid solution were 3 and 12, respectively. The tensile strength and elongation at break of the serous film are above 5N/mm~2 and 90% respectively. Skin pulp can supplement and improve the loss and denaturation of collagen in leathers and improve its physical properties. This study provides a new idea for the reinforcement and protection of leathery relics.
