Problems solved by technology
Due to the high oil content and excellent compatibility, but poor water solubility, it cannot be fully emulsified. When the environment is >40°C (such as exporting to Africa), the oil seeps and pollutes the outer packaging of crayons and painting materials, which affects the surface brightness of the product and the production time of the product. Possible problems such as demoulding

Embodiment 1-4
[0042] As shown in Table 2, it is the wax products and their performance data prepared by the above method in Examples 1-4 of the present invention.
[0043] Table 2: Formulas and performance parameters of Examples 1-4 (the amount of raw materials added is parts by weight)
[0044]
[0045] It has been proved by experiments that the amount of microcrystalline wax added has a direct relationship with oil leakage. figure 2 It reflects the relationship between the amount of microcrystalline wax added and the melting point and oil leakage of wax products. The graph shows that: when the amount of microcrystalline wax added is At 8%, the melting point reaches the standard and there is no oil leakage, but as the amount of microcrystalline wax added increases, the cost will increase. Tests have shown that when the amount of microcrystalline wax added is 8% to 10%, it is the most ideal, and the cost can be effectively controlled.

Abstract
The invention discloses a special wax for a color painting material, which comprises the following raw materials in percentage by weight: 60-66% of full-refined paraffin, 8-18% of microcrystalline wax, 2-4% of white oil, 1-2% of polyethylene wax and 18-22% of nonionic emulsifier, wherein the melting point of the full-refined paraffin is 64-70 DEG C, and the melting point of the microcrystalline wax is 80-90 DEG C. The special wax disclosed by the invention has the advantages of high water solubility and excellent compatibility, and can be sufficiently dissolved in organic / inorganic pigments and filling materials; and the special wax has low oil content, and thus, can not permeate oil to pollute the external packaging of crayons and painting materials, thereby avoiding influencing the surface brightness of the product and being beneficial to product demolding in the production process.
Description
technical field [0001] The invention relates to an industrial wax, in particular to a special wax for color painting materials. Background technique [0002] Special wax for color painting materials, specially used for watercolor color crayons, watercolor painting materials, etc. At present, it is mainly used for crayons and watercolor paints. The education syllabus formulated by the Shanghai Municipal Education Commission stipulates that water-soluble colored crayons are used to replace the non-water-soluble crayons used previously for the enlightenment education of students. Due to the existing water-soluble wax, the product quality does not meet the standards, mainly because it does not meet the comprehensive performance index requirements of the wax for color painting materials products. Therefore require trial production of special waxes for color painting materials that meet its comprehensive performance indicators. [0003] Water-soluble wax for color painting mate...
