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
The present invention relates to a kind of agent preparation method that eases back, especially a kind of agent preparation method that eases back for stiff leather historical relic.
Background technology
Chinese history is long; unearthed leatherware historical relic One's name is legion, but there is in various degree aging, special in dry northwest China in many leather historical relics; that unearthed leatherware historical relic has all occurred is stiff, the situation of cracking, not folding, needs protection badly.
At present of a great variety about the agent that eases back of leather, but be nearly all that the composition of its agent that eases back is not also suitable for historical relic for dress ornament series products such as fur clothing, leather shoes, suitcases, what have also can cause again and damage historical relic.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and object is to prepare a kind of for stiff leather historical relic, and can be to the hurtful agent that eases back of historical relic.
The present invention solves the technical scheme that its technical problem adopts: comprise the following steps:
1) in natural phospholipid, adding volume fraction is 75% lactic acid solution, and lactic acid solution consumption is 1～3% of natural phospholipid quality;
2) above-mentioned mixing liquid is carried out to heating in water bath limit, limit stir process, the time is 1～3h, and temperature is 50～70 ℃;
3), in the front 30min of above-mentioned heated and stirred process, adding gradually massfraction is 30% hydrogen peroxide solution;
4), after above-mentioned heated and stirred end of processing, the sodium hydroxide solution titration mixing liquid that is 5% with massfraction, to neutral, carries out vacuum-drying to mixing liquid afterwards, obtains Hydroxylated Phospholipids;
5) by carrying out compositely with hydrophilic amino silicone oil, tea saponin, deionized water on above-mentioned Hydroxylated Phospholipids, carry out stirring and emulsifying, obtain the agent that eases back.
Described hydrogen peroxide solution, its consumption is 5～15% of natural phospholipid quality.
In described step 5), each composition quality content is: Hydroxylated Phospholipids 15～25%, and hydrophilic amino silicone oil 5～15%, tea saponin 0.5%, remains as deionized water.
The effect that the present invention is useful is: one, with strong points, be directed to especially easing back of stiff leather historical relic; Two, successful, is applied to stiff leather, and its pliability is increased; Three, leather historical relic is had no side effect, can not cause secondary to damage to historical relic.
