Method for extracting shellac wax and shellac wax prepared by this method
A shellac wax, shellac technology, applied in the direction of recovery/refinement of fatty substances, recycling technology, production of fat, etc., can solve the problem that the shellac wax refining technology is immature, cannot realize industrialized large-scale production, and has not been used in any way, etc. problem, to achieve the effect of environmental protection, less impurities, and cheap recycling

Embodiment 1
[0033] According to the following steps, the above filter residue is refined:
[0034] 1) Add the filter residue to a wax-melting kettle with a concentration of 5% sodium chloride solution, control the weight of the sodium chloride solution to be 10 times the weight of the filter residue, heat and stir at a stirring rate of 100r / min, boil for 1 hour, and let stand After cooling, the lac wax floats on the surface of the water and forms a relatively hard solid wax because the density is lower than that of the water and is insoluble in water, while the impurities are precipitated at the bottom because the density is higher than that of the water, and the solid and liquid are separated, and the solid wax is taken out and scraped off The attachment on its lower surface promptly obtains lac hair wax;
[0035] 2) After shellac hair wax is pulverized into fine particles with a particle size of 20 orders, add in acetone solution (concentration 99%), the weight of acetone solution is 3 ...
Embodiment 2
[0042] The filter residue is refined according to the following steps:
[0043] 1) adding the filter residue to the wax melting kettle containing the calcium chloride solution with a concentration of 1%, controlling the calcium chloride solution weight to be 15 times the weight of the filter residue, heating and stirring, the stirring rate was 100r / min, boiled for 2 hours, and the Set to cool, shellac wax floats on the surface of the water liquid because its density is lower than that of the water liquid and is insoluble in water and forms a relatively hard solid wax, while the impurities are precipitated at the bottom because the density is higher than that of the water liquid, the solid-liquid separation, take out the solid wax, scrape Remove the attachments on its lower surface to obtain shellac hair wax;
[0044] 2) pulverizing the shellac hair wax into granularity is 20 order fine particles, adding the pulverized shellac hair wax in the ethanolic solution (concentration 9...
Embodiment 3
[0052] Purify the shellac lye filter residue in the production process of bleached shellac according to the following steps:
[0053] 1) adding the filter residue into the wax melting kettle containing the calcium chloride solution with a concentration of 10%, controlling the calcium chloride solution weight to be 8 times of the filter residue weight, heating and stirring, and the stirring rate was 100r / min, boiled for 0.5 hour, and kept the filter residue statically. Set to cool, shellac wax floats on the surface of the water liquid because its density is lower than that of the water liquid and is insoluble in water and forms a relatively hard solid wax, while the impurities are precipitated at the bottom because the density is higher than that of the water liquid, the solid-liquid separation, take out the solid wax, scrape Remove the attachments on its lower surface to obtain shellac hair wax;
[0054] 2) pulverizing the shellac hair wax to granularity is 20 mesh fine partic...
