Technical Field

The invention belongs to the field of drawing tools, and particularly relates to a color clay crayon and a preparation method thereof.

Background

The color clay as an intelligence toy for children can be used for kneading various creative shapes, exerts the practical ability and imagination ability of children, and can develop the intelligence of children while playing games. The color clay is a precursor of the plasticine, but the color clay is improved greatly relative to the plasticine in the process and material, the color clay is comfortable in hand feeling and not sticky when kneaded and molded, the color clay can be restored to be soft by adding a proper amount of water after being naturally dried, the effect of playing repeatedly is achieved, and the plasticine is poor in experience. Most of color muds are prepared by mixing flour and oil, and finished products prepared by the color muds are easy to pulverize on the surface after being placed for a long time and have the defect that the color muds cannot be stored for a long time. The crayon is a tool commonly used by children during drawing, is enjoyed by children with rich colors, and can exert various imagination of the children to create creative works while drawing. The crayon is simple in manufacturing process, the main components of the crayon are paraffin and pigment, most crayon is poured and molded, and the preparation method is limited by the traditional formula.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a color clay crayon which can keep the plasticity of color clay under the condition of wetting, can be manually kneaded into different shapes, can keep the shape after being dried by air, simultaneously embodies the writing characteristic of the crayon, and can be repeatedly used.

In order to achieve the technical purpose, the technical scheme of the invention is as follows:

the color clay crayon comprises the following components in parts by mass: 2-10 parts of polyvinyl alcohol, 10-30 parts of water, 0.5-2 parts of glycerol, 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 filler, 1-3 parts of pigment and 0.2-1 part of borax.

The filler is one or more of kaolin, talcum powder and calcium carbonate.

A preparation method of a color clay crayon comprises the following steps:

step 1, preparing glue solution: adding 2-10 parts by mass of polyvinyl alcohol and 10-30 parts by mass of water at the temperature of 70-100 ℃ to completely dissolve the polyvinyl alcohol in the water, and continuously stirring for 1-4h at the temperature. Then 0.5-2 parts by mass of glycerol is added for moisturizing the material and slowing down the dehydration speed of the material; and finally, adding 5-10 parts by mass of silicone oil, wherein the silicone oil is added to ensure that the material is not easy to have the phenomena of pulverization and cracking after being dried, and the polyvinyl alcohol sol and the silicone oil are fully mixed.

Furthermore, the polyvinyl alcohol and water are soaked for 1 hour at room temperature, so that the polyvinyl alcohol and water are more easily dissolved.

Step 2, preparing synthetic wax: melting 10-30 parts by mass of solid paraffin, 3-10 parts by mass of polyethylene wax and 2-10 parts by mass of stearic acid at the temperature of 70-100 ℃, adding the molten synthetic wax into the glue solution, and continuously stirring for 2-4 hours at the temperature. The addition of the polyethylene wax can increase the strength and gloss of the crayon relative to crayons made from conventional paraffin wax. Stearic acid can make the crayon smoother and smoother during writing and can make the wax better dispersible in the system.

Step 3, preparing color clay: 10-20 parts by mass of calcium stearate is added into the sol synthetic wax, and the calcium stearate can increase internal lubricity so that the crayon can write more smoothly. Then adding 10-15 parts by mass of kaolin as filler, and continuing to fully stir for 0.5-1.5 h. Then adding 1-3 parts by mass of pigment, and fully stirring for 1-2 h. Finally, 0.2-1 part by mass of borax is added to be fully stirred, then the material is discharged, and the color mud is obtained after cooling.

From the above description, it can be seen that the present invention has the following advantages:

1. the invention solves the technical defects of color clay and crayons, provides a color clay crayon which can keep soft when being wet, has the characteristics of plasticine, exerts the creative thinking ability and color perception of children, and cultivates the practical ability of children to shape various models; the crayon can keep the shape after natural air drying, and simultaneously can play the role of the crayon, and various colors are modulated for writing and drawing, thereby being beneficial to cultivating the drawing interest of children and playing the drawing creativity; after being dried by air, the fabric is added with a proper amount of water and then is recovered to be soft, can be repeatedly used, and has the environment-friendly effect while playing the multiple functions.

2. The invention has simple manufacturing process, easy realization of industrialization, comfortable product feeling, no stickiness and smooth writing.
