Embodiment 1

[0018] A kind of colored clay crayon, adopts following steps to prepare:

[0019] Step 1, preparation of glue solution: under the temperature condition of 70°C, add 2 mass parts of polyvinyl alcohol and 30 mass parts of water to completely dissolve the polyvinyl alcohol in water, and keep stirring at this temperature for 1-4 hours. Then add 0.5 parts by mass of glycerin; finally add 8 parts by mass of silicone oil to obtain glue;

[0020] Furthermore, the polyvinyl alcohol and water are first soaked at room temperature for 1 hour, which makes it easier to dissolve.

[0021] Step 2, preparing synthetic wax: under the temperature condition of 70°C, melt 15 parts by mass of solid paraffin, 5 parts by mass of polyethylene wax and 4 parts by mass of stearic acid, add the melted synthetic wax to the glue, and Continue stirring for 2 h at the above temperature;

[0022] Step 3, preparing colored clay: adding 20 mass parts of calcium stearate to the above-mentioned synthetic wax, th...

[0025] A kind of colored clay crayon, adopts following steps to prepare:

[0026] Step 1, preparation of glue solution: at a temperature of 100°C, add 10 parts by mass of polyvinyl alcohol and 30 parts by mass of water to completely dissolve the polyvinyl alcohol in the water, and keep stirring at this temperature for 4 hours. Then add 2 mass parts of glycerin; finally add 6 mass parts of silicone oil to obtain glue;

[0027] Furthermore, the polyvinyl alcohol and water are first soaked at room temperature for 1 hour, which makes it easier to dissolve.

[0028] Step 2, preparing synthetic wax: under the temperature condition of 100°C, melt 15 parts by mass of paraffin wax, 4 parts by mass of polyethylene wax and 6 parts by mass of stearic acid, add the melted synthetic wax to the glue, and Continue stirring for 4h at the above temperature;

[0029] Step 3, preparation of colored clay: add 10 mass parts of calcium stearate to the above-mentioned synthetic wax, then add 10 mas...

Embodiment 3

[0031] A kind of colored clay crayon, adopts following steps to prepare:

[0032] Step 1, preparation of glue: at 90°C, add 8 parts by mass of polyvinyl alcohol and 20 parts by mass of water to completely dissolve the polyvinyl alcohol in water, and keep stirring at this temperature for 3 hours; then add 0.5 parts by mass of Parts of glycerin; Finally, add 8 parts by mass of silicone oil to obtain glue;

[0033] Furthermore, the polyvinyl alcohol and water are first soaked at room temperature for 1 hour, which makes it easier to dissolve.

[0034] Step 2, preparing synthetic wax: under the temperature condition of 90°C, melt 20 parts by mass of solid paraffin, 8 parts by mass of polyethylene wax and 6 parts by mass of stearic acid, add the melted synthetic wax to the glue, and Continue stirring for 3h at the above temperature;

[0035] Step 3, preparation of colored clay: Add 15 parts by mass of calcium stearate to the above-mentioned synthetic wax, then add 7 parts by mass ...

Abstract

The invention belongs to the field of painting tools, and particularly relates to a colored clay crayon which is prepared from, by mass, 2-10 parts of polyvinyl alcohol, 10-30 parts of water, 0.5-2 parts of glycerinum, 5-10 parts of silicone oil, 10-30 parts of solid paraffin, 3-10 parts of polyethylene wax, 2-10 parts of stearic acid, 10-20 parts of calcium stearate, 10-15 parts of a filler, 1-3 parts of a pigment and 0.2-1 part of borax, and a specific preparation method is provided. The technical defects of colored clay and crayons are overcome, the plastic characteristic of the colored clay is kept under the wetting condition, the colored clay can be manually pinched into different shapes, the writing characteristic of the crayons is reflected while the colored clay crayon is kept shaped after air drying, and the colored clay crayon can be repeatedly used.

Description

technical field [0001] The invention belongs to the field of painting tools, and in particular relates to a colored clay crayon and a preparation method thereof. Background technique [0002] As a kind of educational toy for children, colored clay can be used to make various creative shapes, develop children's hands-on ability and imagination, and develop children's intelligence while playing games. The color clay itself is the predecessor of the plasticine, but its technology and material are much improved compared to the plasticine. The color clay feels comfortable and non-sticky when kneading, and it can be restored to its softness by adding an appropriate amount of water after it dries naturally. It has the effect of playing repeatedly, while plasticine has a relatively poor experience. Most colored clay is made of flour and oil, and the surface of the finished product is easy to pulverize after being placed for a long time, which has the disadvantage that it cannot be ...
