Abstract
The invention discloses a preparation method for a reconstructed amber. The preparation method comprises the steps that amber detritus which is large in impurity content, low in transparency and dark in color is subjected to impurity removing and smashed to be in 100-200 meshes, and the powder is subjected to pressing molding at the pressure of 10-30 MPa; a pressed amber is heated up to 330 DEG C-360 DEG C with the heating rate being 3-5 DEG C/min under the reducing condition, heat preservation is conducted for 0.5-3 h, and the cooling rate is 0.2-10 DEG C/min; and the obtained reconstructed amber is subjected to polishing and burnishing, and the large amber which is little in impurity content, high in transparency and bright in color is obtained. According to the preparation method for the reconstructed amber, the physicochemical property of the reconstructed amber prepared through the method is the same as that of a natural amber, processed leftover materials of the natural amber or the amber detritus which is large in impurity content, low in transparency and dark in color can be reconstructed into the large amber which is little in impurity content, high in transparency and bright in color. The preparation method for the reconstructed amber is high in operability, low in cost, free of pollution and suitable for industrial production.
Description
Technical field
The present invention relates to the preparation method of a kind of reconstructed amber, belong to jewel field.
Background technology
In recent years, along with drastically reducing and the growth of Jewelry Market of this several years natural ambers of the state such as Russian, Polish, supply falls short of demand for the bulk natural amber of Gem Grade, and the price of amber raw material goes up 50 ~ 100% every year.Meanwhile, machining chips and the inferior raw material of amber are not used and do not have market, and therefore reconstructed amber is favored by masses.The now reconstructed amber in Jewelry Market, be typically rendered as that transparency is low, be faint in color, Ultraluminescence is uneven, internal containing more " trace of blood " shape oxide layer, and the bubble aligned containing flat elongation.This is owing to the reconstructed amber in market is to melt in atmosphere, part amber chip top layer and oxygen react and form red oxide layer, or during cooling, rate of temperature fall too fast part bubble remains in reconstructed amber, has obvious identification mark after making shaping inside amber.But high, the bright amber of transparency is more liked by masses, the problems demand therefore promoting reconstructed amber quality solves.
Summary of the invention
The technical problem to be solved in the present invention be Jewelry Market amber price can be in any more, Gem Grade product problem less and less.
It is an object of the invention to provide the preparation method of a kind of reconstructed amber, by by amber chip decontamination, pulverize, suppress, the technique such as sintering finally prepared impure less, high, the bright bulk amber of transparency；After testing, owing to natural amber taken from by raw material, the chemical property of reconstructed amber is consistent with natural amber；Reconstructed amber Gemmological Characters and natural amber the most quite similar；Specifically include following steps:
(1) amber chip is gone the removal of impurity and is crushed to 100 ~ 200 mesh；
(2) powder pressing forming that step (1) is obtained, under anaerobic, it is warming up to 330 ~ 360 DEG C with the heating rate of 3 ~ 5 DEG C/min, temperature retention time is 0.5 ~ 3h, then 250 ~ 300 DEG C are cooled the temperature to the rate of temperature fall of 5 ~ 10 DEG C/min, cool the temperature to 200 ~ 250 DEG C with the rate of temperature fall of 3 ~ 8 DEG C/min again, then cool the temperature to room temperature with the rate of temperature fall of 0.2 ~ 5 DEG C/min and obtain reconstructed amber.
Preferably, pressure 10MPa ~ 30MPa compressing in step of the present invention (2), the dwell time is 3 ~ 20min.
With the rate of temperature fall of 0.2 ~ 5 DEG C/min, from 200 ~ 250 DEG C, temperature is down to this process of room temperature described in step of the present invention (2) can also carry out in atmosphere.
The high-quality amber kind that transparency is high has Jin Po and blood amber, and when described in step of the present invention (2), whole process is carried out under anaerobic, the amber reproduced is gold amber；Described in step (2) with the rate of temperature fall of 0.2 ~ 5 DEG C/min by temperature from 200 ~ 250 DEG C be down to this process of room temperature carry out in atmosphere time, the amber reproduced is blood amber.
Amber chip of the present invention be natural amber processing remaining sides corner material or containing a large amount of impurity, transparency is low, be faint in color and can not do the natural amber of production marketing.
Beneficial effects of the present invention: the reconstructed amber that method described in this law prepares has physicochemical properties consistent with natural amber, and can by impure more, transparency is low, the amber chip that is faint in color cause again impure less, high, the bright bulk amber of transparency.The preparation method operability height of reconstructed amber, low cost, pollution-free, it is adaptable to industrialized production.Can produce bubble inside when existing method amber reproduces, the method for the invention is by controlling compressing condition, experimental temperature, temperature retention time and rate of temperature fall, and the number of bubbles contained in obtained reconstructed amber can drop to nothing.
