Embodiment 1

[0017] Example 1: Heat 70 parts by weight of 58°C paraffin wax, 10 parts by weight of ethylene polymer and 10 parts by weight of stearic acid to 80-110°C in a reactor, and stir and dissolve for 1-1.5 hours to prepare a mixed wax slurry. The prepared mixed wax slurry is cooled, and the synthetic wax is prepared for subsequent use;

[0018] Put 5 parts by weight of Phthalocyanine Blue, 5 parts by weight of Fast Yellow 10G and 5 parts by weight of Light Calcium Carbonate into 5 parts by weight of white oil, mix and stir them, grind them for 3 times, and measure them with a scraper fineness meter The fineness is 30 μm, and the color paste is prepared for use;

[0019] 90 parts by weight of synthetic wax and 10 parts by weight of color paste are put into a reaction pot, completely melted at 80-110 DEG C, stirred evenly to make crayon paste, poured into a mold, cooled and shaped to obtain crayon.

Embodiment 2

[0020] Example 2: Heat 80 parts by weight of 58°C paraffin wax, 5 parts by weight of ethylene polymer and 5 parts by weight of stearic acid to 80-110°C in a reactor, and stir and melt for 1-1.5 hours to prepare a mixed wax slurry. The mixed wax slurry is cooled to prepare synthetic wax for subsequent use;

[0021] Put 5 parts by weight of Phthalocyanine Blue, 5 parts by weight of Fast Yellow 10G and 5 parts by weight of Light Calcium Carbonate into 5 parts by weight of white oil, mix and stir them, grind them for 3 times, and measure them with a scraper fineness meter The fineness is 30 μm, and the color paste is prepared for use;

[0022] 90 parts by weight of synthetic wax and 10 parts by weight of color paste are put into a reaction pot, completely melted at 80-110 DEG C, stirred evenly to make crayon paste, poured into a mold, cooled and shaped to obtain crayon.

Embodiment 3

[0023] Example 3: Heat 75 parts by weight of 58°C paraffin wax, 9 parts by weight of ethylene polymer and 10 parts by weight of stearic acid to 80-110°C in a reactor, and stir and dissolve for 1-1.5 hours to prepare a mixed wax slurry. The prepared mixed wax slurry is cooled, and the synthetic wax is prepared for subsequent use;

[0024] Put 3 parts by weight of Phthalocyanine Blue, 3 parts by weight of Fast Yellow 10G and 5 parts by weight of Light Calcium Carbonate into 5 parts by weight of white oil, mix and stir them, grind them for 3 times, and measure them with a scraper fineness meter The fineness is 30 μm, and the color paste is prepared for use;

[0025] 90 parts by weight of synthetic wax and 10 parts by weight of color paste are put into a reaction pot, completely melted at 80-110 DEG C, stirred evenly to make crayon paste, poured into a mold, cooled and shaped to obtain crayon.

Abstract

The invention discloses a crayon and a manufacturing method thereof. The crayon is prepared by the following steps: taking paraffin wax, ethylene polymer, stearic acid, pigment and assistants as raw materials; adding the ethylene polymer and stearic acid in the paraffin wax to prepare into a synthetic wax; adding toner and fillers into mineral oil for grinding to prepare into color paste; mixing, melting and evenly stirring the synthetic wax and the color paste to prepare into crayon pulp; and sizing the crayon pulp to prepare into the crayon. The crayon prepared by the invention has the color concentration similar to that of the oil painting stick product and good coloring performance, has no crayon scraps in use, and can not cause pollution to users; in addition, the strength of the crayon can improved.

Description

technical field [0001] The invention relates to a crayon and a manufacturing method thereof. Background technique [0002] Two kinds of drawing tools of crayon and oil pastel are widely used at present, but be subjected to the limitation of traditional formula, crayon has the disadvantages such as low color concentration, bright color not enough. Although oil pastels have high color concentration and bright colors, they are easy to cause pollution to users. Crayons are made by mixing paraffin wax and toner. Paraffin wax is refined from petroleum. It is soft and sticky. Different paraffin waxes have different softening points. Traditional crayon formulas use only paraffin wax to make crayons soft. Use When it is easy to break, and there are a lot of crayon crumbs, the painting is not fluent. Contents of the invention [0003] In order to solve the above problems, the present invention provides a crayon and a production method thereof. The crayon prepared by the method of ...
