Disclosure of Invention
In order to solve the problems, the cinnabar artware raw material powder and the preparation method thereof provided by the invention comprise cinnabar powder and nano copper powder, and the cinnabar artware raw material powder is very stable in chemical property, has rose color and metal reflective luster, bright color, clear print and fine texture, and is very suitable for being used as a cinnabar artware raw material.
Specifically, the invention provides cinnabar artware raw material powder which consists of 92-97% of cinnabar powder and 3-8% of nano copper powder.
The cinnabar powder is fine powder which is sieved by a 150-mesh sieve but not sieved by a 220-mesh sieve.
Further, cinnabar artware raw material powder consists of 94% of cinnabar powder and 6% of nano copper powder.
The cinnabar powder is fine powder which is sieved by a 180-mesh sieve but not sieved by a 200-mesh sieve.
A preparation method of cinnabar artware raw material powder comprises the following steps:
(1) cleaning Cinnabaris with water, pulverizing into granule, soaking in 30-40% sodium sulfide solution for 1-3 hr, filtering, drying Cinnabaris granule, pulverizing in pulverizer, sieving, collecting and sieving with 150 mesh sieve, and sieving with 220 mesh sieve to obtain Cinnabaris powder.
(2) And (3) uniformly mixing the cinnabar powder prepared in the step (1) with the nano copper powder to obtain cinnabar artware raw material powder.
Further: a preparation method of cinnabar artware raw material powder comprises the following steps:
(1) cleaning cinnabar with water, pulverizing into granules, soaking in 35% sodium sulfide solution for 2h, filtering, drying cinnabar granules, pulverizing in a pulverizer, sieving, collecting fine powder of 180 mesh sieve instead of 200 mesh sieve to obtain Cinnabaris powder, and keeping.
(2) And (3) uniformly mixing the cinnabar powder prepared in the step (1) with the nano copper powder to obtain cinnabar artware raw material powder.
The invention has the beneficial effects that:
through years of experience and research on the preparation of cinnabar artware, the cinnabar is 220 meshes, and the prepared artware has excellent color and luster, has rose color and metal reflective luster, and has less rose color, even brown color, dark black color and no metal luster, and cannot form obvious metal luster when being below 150 meshes compared with cinnabar powder with other meshes; above 220 meshes, the prepared artware is pink, even pale white and has no metallic luster, so that in order to ensure the color and quality of cinnabar, the cinnabar powder is preferably subdivided into 150 meshes and 220 meshes, and the prepared cinnabar artware is optimal, except that after the nano copper powder is added in the preparation process of the cinnabar powder, the chemical stability of the cinnabar powder can be obviously improved, and the prepared artware is very bright in color and high in grade.
The beneficial effects of the invention are investigated:
test group 1 is cinnabar artware raw material powder prepared by the invention.
Test group 2: is prepared by mixing 150-220-mesh cinnabar powder and 200-mesh copper powder.
Control group: pulverizing Cinnabaris into 160-220 mesh fine powder.
Carrying out an accelerated stability test under the following test conditions: under the conditions of 40 ℃ temperature and 75% relative humidity, the cover is opened and the storage is carried out for 6 months, and the examination is carried out after 6 months:
and (3) test results:
test group 1: the cinnabar artware raw material powder is bright red, has rose color and metal reflective luster, and has no obvious difference from the raw material powder before the test.
Test group 2: the cinnabar artware raw material powder is not strong in rose color, has slight dark brown color and is weak in metal luster.
Control group: the cinnabar artware raw material powder has weak rose color, even brown color, dark black color and no metallic luster.
Description of the drawings: according to the invention, after the copper powder is added in the preparation process of the cinnabar powder, the chemical stability of the cinnabar powder can be obviously improved, and the effect is optimal by adopting the nano copper powder, and the prepared nano copper powder can improve the specific surface area of the copper powder and activate copper simple substances, can passivate the cinnabar powder better, and can improve the chemical stability of cinnabar, so that a small amount of nano copper powder is preferably added in the preparation process of the cinnabar powder for protection.
