Embodiment 1

[0026] A preparation method of a color-changing pencil holder, comprising the following steps:

[0027] Step 1, take the white pencil shaft and evenly paint several layers of white primer on the white pencil shaft after being ground and polished, so as to obtain a pencil shaft with a flat and smooth surface for use;

[0028] Step 2, take the temperature-changing powder and place it in a refrigeration device to refrigerate until the color of the temperature-changing powder becomes darker completely, then take it out from the refrigeration device, and leave it in the air for later use;

[0029] Step 3, taking the temperature-changing powder and varnish treated in step 2 at a ratio of 15:100, putting the temperature-changing powder into the varnish and stirring until it completely dissolves in the varnish to obtain a color-changing liquid;

[0030] Step 4, taking the color-changing liquid obtained in step 3 and painting several layers on the pencil shaft obtained in step 1, and t...

Embodiment 2

[0033] A preparation method of a color-changing pencil holder, comprising the following steps:

[0034] Step 1, take the white pencil shaft and evenly paint several layers of white primer on the white pencil shaft after being ground and polished, so as to obtain a pencil shaft with a flat and smooth surface for use;

[0035] Step 2, take the temperature-changing powder and place it in a refrigeration device to refrigerate until the color of the temperature-changing powder becomes darker completely, then take it out from the refrigeration device, and leave it in the air for later use;

[0036] Step 3, taking the temperature-changing powder and varnish treated in step 2 in a ratio of 20:100, putting the temperature-changing powder into the varnish and stirring until it completely dissolves in the varnish to obtain a color-changing liquid;

[0037] Step 4, taking the color-changing liquid obtained in step 3 and painting several layers on the pencil shaft obtained in step 1, and t...

Embodiment 3

[0040] A preparation method of a color-changing pencil holder, comprising the following steps:

[0041] Step 1, take the white pencil shaft and evenly paint several layers of white primer on the white pencil shaft after being ground and polished, so as to obtain a pencil shaft with a flat and smooth surface for use;

[0042] Step 2, take the temperature-changing powder and place it in a refrigeration device to refrigerate until the color of the temperature-changing powder becomes darker completely, then take it out from the refrigeration device, and leave it in the air for later use;

[0043] Step 3, taking the temperature-changing powder and varnish treated in step 2 in a ratio of 30:100, putting the temperature-changing powder into the varnish and stirring until it completely dissolves in the varnish to obtain a color-changing liquid;

[0044] Step 4, taking the color-changing liquid obtained in step 3 and painting several layers on the pencil shaft obtained in step 1, and t...

Abstract

The invention relates to the field of preparation of pencils and in particular relates to a preparation method of a color-changing leadholder. The preparation method comprises the following steps: S1, after sanding and polishing a white pencil stick, uniformly smearing the white pencil stick with a plurality of layers of white primers to obtain a leadholder which is level and smooth in surface for laser use; S2, putting temperature change powder in a refrigerating device to be refrigerated till the color of the temperature change powder is fully darkened and taking out the powder from the refrigerating device, and leaving the powder to stand in air for laser use; S3, taking the temperature change powder and gloss oil treated in the S2 in a proportion of 15: (100-30): 100 and stirring the temperature change powder in the gloss oil till the powder is fully dissolved in the gloss oil to obtain a color-changing liquid; and S4, smearing the leadholder obtained in the S1 with the color-changing liquid obtained in the S3 and drying the leadholder to obtain the leadholder. The preparation method provided by the invention has the beneficial effects that the leadholder is simple to prepare, the color of the holder is changeable, and the color-changing effect is stable.
