Improved hematoxylin dye liquor and preparation method thereof

The invention discloses improved hematoxylin dye liquor and a preparation method thereof. The improved hematoxylin dye liquor comprises the following raw materials in parts by weight: 1-2 parts of hematoxylin powder, 3-8 parts of 1, 2-propylene glycol, 8-12 parts of absolute ethyl alcohol, 4-6 parts of aluminum sulfate octadecahydrate, 1.0-2.0 parts of aluminum potassium sulfate dodecahydrate, 0.1-0.5 part of an oxidizing agent, 1-2 parts of glacial acetic acid and 68-81 parts of distilled water. The surface of the hematoxylin dye liquor prepared by the method is almost not covered by a metal oxide film, precipitates separated out from a lower layer are few, the cell nucleus staining power is high, the hematoxylin dye liquor can be dyed into purple blue within 3 minutes, the service life is long, and the number of stained sections is three times that of a classic formula. 本发明公开了一种改良的苏木精染液及其制备方法，包括以下重量份数配比的原料，苏木精粉1-2份，1,2-丙二醇3-8份，无水乙醇8-12份，十八水硫酸铝4-6份，十二水硫酸铝钾1.0-2.0份，氧化剂0.1-0.5份，冰醋酸1-2份，蒸馏水68-81份。本发明制备得到的苏木精染色液
