Abstract
The invention discloses a method for reinforcing a dry and hard fragile leather historical relic. The method includes the first step of placing and soaking the leather historical relic in a sodium chloride solution with the mass fraction of 3%-6%, the second step of placing the leather historical relic processed through the first step in a water bath kettle containing a polyethylene glycol 400 solution with the mass concentration of 30%, the third step of placing the leather historical relic processed through the second step in an ethanol solution with the mass concentration of 50% to be soaked for 20 min-60 min, the fourth step of placing and soaking the leather historical relic processed through the third step in a collagen solution with the mass concentration of 3%-5%, and the fifth step of placing and soaking the leather historical relic processed through the fourth step in an ethylene glycol diglycidyl ether solution with the mass concentration of 2%-4%, then taking out the leather historical relic, and airing the leather historical relic to obtain the reinforced historical relic. The method has the advantages that the effect is remarkable, the method is applied to hardened fur, and elasticity and other mechanical properties of the fur are improved; the method is simple, and operation is simple and convenient; no secondary damage can be caused to the fur historical relic.
Description
Technical field
The present invention relates to a kind of leathercraft reinforcement means for stiff fragility, especially a kind of method for reinforcing and protecting of the leathercraft historical relic for stiff fragility.
Background technology
In the very long history of China, Chinese people start to utilize animal fur to make clothes with resisting cold very early.In the last few years, along with constantly carrying out archaeological excavation, be unearthed the leathercraft historical relic of a large amount of fineness.Due to leathercraft historical relic long buried under, inner moisture and fat divide a large amount of loss, and collagen protein is hydrolyzed in a large number and is oxidized, and leathercraft historical relic becomes incomparably stiff and fragile, and be in one and touch namely broken stage, urgent need is protected.
summary of the inventionthe invention provides a kind of reinforcement means for stiff fragile leathercraft historical relic for this reason, thus suitable leathercraft is softened, well can play protected effect to the leathercraft historical relic of stiff fragility.
Adopt following technical scheme: a kind of reinforcement means for stiff fragile leathercraft historical relic for this reason, it is characterized in that adopting following steps:
A) by leathercraft historical relic, put into massfraction be 3 ~ 6% sodium chloride solution soak 1h, liquor capacity/ml and leather quality/g ratio are 6 ~ 10;
B) leathercraft historical relic step A processed, putting into containing mass concentration is 30% poly(oxyethylene glycol) 400 solution water bath, and temperature is 70-80 degree, and the time is 2-3h;
C) leathercraft historical relic step B processed, put into containing mass concentration be 50% ethanolic soln soak 20 ~ 60min;
D) the leathercraft historical relic after step C being processed, putting into containing mass concentration is that 3 ~ 5% collagen solutions soak 20 ~ 40min, liquor capacity/ml and leather quality/g ratio is 6 ~ 10;
E) being put into by the leathercraft historical relic after complete for D step process containing mass concentration is that 2 ~ 4% ethylene glycol diglycidylether solution soak 1 ~ 2h, liquor capacity/ml and leather quality/g ratio is 6 ~ 10; Subsequently cortex historical relic is taken out, after drying, both can obtain the historical relic after reinforcing.
The effect that the present invention is useful is: one, achieve noticeable achievement, and be applied to sclerosis fur, the mechanical propertys such as the bullet of fur improve; Two, method is simple, easy and simple to handle; Three, man-made further destroy can not be produced to fur historical relic.
