Abstract
The invention relates to a preparation method of a dry and hard leather cultural-relic softener. The preparation method specifically comprises the following steps: adding lactic acid and hydrogen peroxide into natural plant oil, heating and stirring for modification, conducting titration to neutral by the use of a sodium hydroxide solution, drying to obtain hydroxylated modified plant oil; and finally compounding the hydroxylated modified plant oil with hydrophilic amino silicon oil, essence, microcrystalline wax and deionized water so as to prepare the softening polish product. The preparation method provided by the invention has advantages of strong pertinency, obvious effect, no damage to cultural relics and the like.
Description
Technical field
The present invention relates to one to ease back agent preparation method, especially a kind ofly to ease back agent preparation method for stiff leather cultural relic.
Background technology
China uses the history of leather of long standing and well established, and far away from protohistoric, people have started apply grease on animal skin.Since modern age, along with archaeology deepens continuously, a large amount of leather cultural relic of being unearthed, but the most of historical relics be unearthed all are subject to aging and breakage in various degree, are badly in need of protection.
The present invention adopt for the aging of leather cultural relic and breakage, ease back compared with agent with the major part in market, the man-made further destroy of leather cultural relic can not be caused.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and object is that preparation is a kind of can make leather ease back for stiff leather cultural relic, leather can be made simultaneously again to keep fine and smooth and gloss, can also remove the method for the agent that eases back of peculiar smell.
The present invention solves the technical scheme that its technical problem adopts: comprise the following steps:
1) be added in an amount of 1 ~ 3% of natural phant oil quality in crude vegetal, concentration is 75%(volume fraction) lactic acid solution, then above-mentioned mixing liquid is carried out heating in water bath limit, limit stir process, the time is 1 ~ 2h, and temperature is 50 ~ 70 DEG C;
2) before above-mentioned heated and stirred process, in 30min, add 30%(massfraction gradually) hydrogen peroxide solution;
3) after above-mentioned heated and stirred end of processing, use 5%(massfraction) sodium hydroxide solution titration mixing liquid to neutral, afterwards vacuum-drying is carried out to mixing liquid, obtains hydroxylation modified vegetable oil;
4) above-mentioned hydroxylation modified vegetable oil and hydrophilic amino silicone oil, essence, Microcrystalline Wax, deionized water are carried out composite, carry out stirring and emulsifying, obtain the agent that eases back.
Described hydrogen peroxide solution, its consumption is 5 ~ 15% of natural phant oil quality.
In described step 4), each composition quality content is: hydroxylation modified natural vegetables oil 10 ~ 20%, hydrophilic amino silicone oil 5 ~ 10%, and essence 0.5 ~ 1%, Microcrystalline Wax 5 ~ 10%, remaining as deionized water.
The effect that the present invention is useful is: one, with strong points, is directed to easing back of stiff leather cultural relic especially; Two, successful, makes leather again keep fine and smooth and gloss, can also reach deodorization; Three, leather cultural relic is had no side effect, secondary damage can not be caused to historical relic.
Embodiment
The invention will be further described below:
