Method for preparing wax tree wax with wax tree seed

Abstract

The invention belongs to the technical field of preparing a Japan wax from Japanese wax tree seeds. The invention is characterized in that: a two-time filtration process is adopted for filtration; that is to say, a primary filtration adopts a 400-mesh stainless steel net to carry out extraction filtration through a barrel type filter; a secondary filtration is a composite filtration carried out by a plate frame filter press, filter liquor is firstly filtrated by a piece of tweel cotton filter cloth, then is filtrated by a piece of industrial filter paper and is finally filtrated by a piece of industrial filter cloth, and the temperature during the whole filtration process is controlled from 70 to 80 DEG C; No. 120 solvent naphtha is taken as an extraction solvent, the addition quantity ratio between the extraction solvent and the Japan wax tree seed powder is 3 to 1 (volume ratio), and extraction is carried out for 50-60min when a temperature is raised to 90-100 DEG C; 320-mesh active carbon is taken as a decolorizer, the addition quantity of the active carbon is about 5 percent of the weight of leaching liquor, a decolorizing temperature is controlled from 110 to 115 DEG C, and the active carbon decolorizing time is controlled from 45 to 55min. Due to the technologies of raw material decladding separation, absorbent decolorizing, two-time filtration, etc., a Japan wax product has higher yield, better purity and quality, higher added value and comprehensive utilization rate, lower production cost and more environmental protection.

Description

technical field [0001] The invention relates to a method for preparing wild sumac wax from wild sumac seeds, and belongs to the technical field of natural plant wax extraction and processing. Background technique [0002] The production areas of lacquer trees in my country have been mainly producing raw lacquer, and the processing of lacquer seeds has not been paid enough attention. The lacquer wax and lacquer oil are mainly produced by machine pressing or boiling. In some places, the processing of lacquer wax and lacquer oil has not been separated. The wax yield of this traditional processing method is only 15% to 20%, while the lacquer wax content in the lacquer seeds is about 40% to 45%, so a large amount of lacquer wax remains in the lacquer seeds. In addition, the lacquer wax processed by local methods has high water content and impurity content, dark green or gray green color, ugly appearance, soft texture, sticky touch, fishy smell, dull surface, high cost of deep-pro...

Problems solved by technology

Although the process equipment is relatively simple, using a variety of organic solvents not only requires a large amount of solvent, but also the cost of separation and recovery is high, and the industrial implementation is of little significance

[0005] Supercritical extraction has its special advantages, but supercritical extraction technology still faces many difficulties: high-pressure equipment investment and maintenance costs are high, design and manufacturing technology requirements are high, extraction kettles cannot be operated continuously, and production capacity is low

These engineering problems still need to be further solved, thus limiting the practical application of supercritical extraction technology in the production of wild sumac wax
