Problems solved by technology

[0002] China has a long history, and there are a large number of unearthed leather cultural relics, but many leather cultural relics are aging to varying degrees, especially in the dry climate of Northwest China, the unearthed leather cultural relics are dry, cracked, and not resistant to folding. in need of protection
[0003] At present, there are many types of softening agents for leather, but almost all of them are for clothing products such as leather clothing, leather shoes, and leather bags. The ingredients of the softening agent are not suitable for cultural relics, and some will cause further damage to cultural relics

Embodiment 1

[0015] Embodiment 1: a kind of softening agent preparation method for dry hard leather cultural relics, comprises the following steps:

[0016] 1) Add lactic acid solution with a volume fraction of 75% to natural phospholipids, and the amount of lactic acid solution is 1% of the mass of natural phospholipids;

[0017] 2) Heat the above mixed liquid in a water bath while stirring, the time is 2 hours, and the temperature is 65°C;

[0018] 3) Within the first 30 minutes of the above heating and stirring process, gradually add hydrogen peroxide solution with a mass fraction of 30%, and the amount of hydrogen peroxide solution is 15% of the mass of natural phospholipids;

[0019] 4) After the above-mentioned heating and stirring process is completed, the mixed liquid is titrated to neutrality with a sodium hydroxide solution having a mass fraction of 5%, and then the mixed liquid is vacuum-dried to obtain a hydroxylated modified phospholipid;

[0020] 5) Compound the above-mentio...

Abstract

The invention relates to a preparation method of a softening agent for hard and dry leather cultural relics. The preparation method specifically comprises the following steps: adding lactic acid and hydrogen peroxide into natural phospholipid, and heating and stirring to modify; then, titrating to neutral by sodium hydroxide liquor and drying to obtain hydroxylated modified phospholipid; and finally, compounding phospholipid with hydrophilic amino silicon oil, tea saponins and deionized water to prepare a softening agent product. The preparation method provided by the invention has the advantages of strong pertinence, remarkable effect, harmlessness to cultural relics and the like.

Description

technical field [0001] The invention relates to a method for preparing a softening agent, in particular to a method for preparing a softening agent for dry and hard leather cultural relics. Background technique [0002] China has a long history, and there are a large number of unearthed leather cultural relics, but many leather cultural relics are aging to varying degrees, especially in the dry climate of Northwest China, the unearthed leather cultural relics are dry, cracked, and not resistant to folding. In desperate need of protection. [0003] At present, there are many kinds of softening agents for leather, but almost all of them are for clothing products such as leather clothes, leather shoes, and leather bags. The ingredients of the softening agents are not suitable for cultural relics, and some will cause further damage to cultural relics. Contents of the invention [0004] The present invention aims to solve the above-mentioned shortcomings of the prior art, and ...
