[0030] The present invention also provides a kind of preparation method of charcoal pencil for art drawing, specifically implement according to the following steps:

[0031] Step 1, preparing charcoal core;

[0032] Step 1.1, prepare the sterilizing material, use the conventional pyrolysis process with the final carbonization temperature of 600-800°C to crush the bamboo charcoal to make 80-200 mesh high adsorption capacity powdery charcoal; put it into water to heat and stir to form High-temperature carbon-water suspension, wherein, the mass volume ratio (g / ml) of high-temperature carbon-water is 1:5; Then 5% (W / V) nano-TiO 2 and 4% (W / V) nano-TiO 2 The antibacterial agent is stirred in water to make a mixed emulsion; the nano-TiO 2 and nano TiO 2 The mixed emulsion of antibacterial agent is added to the high-temperature carbon-water suspension and fully stirred at a volume ratio of 1:5 to obtain the emulsion of the bactericidal material; then conventionally evaporated and ...

Embodiment 1

[0038] A method for preparing a charcoal pencil for art painting, specifically implemented according to the following steps: the bamboo charcoal is pulverized by a conventional pyrolysis process with a final carbonization temperature of 700° C. to make 120 mesh high adsorption capacity powdery charcoal; put it into water Heating and stirring to form a high-temperature charcoal-water suspension, wherein the mass-volume ratio (g / ml) of high-temperature charcoal to water is 1:5; then 5% (W / V) nano-TiO 2 and 4% (W / V) nano-TiO 2 The antibacterial agent is stirred in water to make a mixed emulsion; the nano-TiO 2 and nano TiO 2 The mixed emulsion of antibacterial agent is added to the high-temperature carbon-water suspension and fully stirred at a volume ratio of 1:5 to obtain the emulsion of the bactericidal material; then conventionally evaporated and dried; the following components are weighed according to parts by mass: 12 parts of clay powder , 40 parts of charcoal, 40 parts of...

Embodiment 2

[0040] A method for preparing a charcoal pencil for art painting, specifically implemented according to the following steps: the bamboo charcoal is pulverized by a conventional pyrolysis process with a final carbonization temperature of 600° C. to make 200 mesh high adsorption capacity powdery charcoal; put it into water Heating and stirring to form a high-temperature charcoal-water suspension, wherein the mass-volume ratio (g / ml) of high-temperature charcoal to water is 1:5; then 5% (W / V) nano-TiO 2 and 4% (W / V) nano-TiO 2 The antibacterial agent is stirred in water to make a mixed emulsion; the nano-TiO 2 and nano TiO 2 Add the mixed emulsion of antibacterial agent to the high-temperature carbon-water suspension and fully stir at a volume ratio of 1:5 to obtain the emulsion of the bactericidal material; then evaporate and dry conventionally; weigh the following components according to parts by mass: 10 parts of clay powder, 45 parts of charcoal, 35 parts of graphite powder...

Abstract

The invention discloses a charcoal pencil for art painting. The charcoal pencil consists of the following components in parts by mass: 10-15 parts of clay powder, 35-45 parts of charcoal, 35-45 parts of graphite powder, 10-15 parts of high-color carbon black and 3-8 parts of a sterilizing material. The invention discloses a making method of the charcoal pencil for art painting; the making method comprises the following steps: making a charcoal pencil refill, soaking the charcoal pencil refill in an ethyl acetate solution which is 85% in concentration for 2h, coating a primer, milling top, coating UV paint and milling tip. According to the charcoal pencil for art painting disclosed by the invention, the UV paint layer is not easy to fall off and the problem of paint peeling off due to poor bonding between the primer and the charcoal pencil refill in a painting process is avoided; and meanwhile, the charcoal pencil has certain functions of inhibiting bacteria, sterilizing as well as adsorbing and decomposing harmful and toxic substances.

Description

technical field [0001] The invention belongs to the technical field of stationery, and in particular relates to a charcoal pencil for art drawing, and also relates to a preparation method of the charcoal pencil for art drawing. Background technique [0002] Most of the charcoal sticks are fired from willow twigs. There are differences between thick, thin, soft and hard. They are used for different picture effects. You can use softer charcoal pens to make drafts at the beginning of the painting, because it is easy to wipe off. , can be corrected repeatedly without damaging the drawing paper, and then use a harder charcoal pen when modifying details. [0003] Charcoal is also a common tool for sketching. The main raw material of charcoal pencils is charcoal powder. Charcoal is produced by incomplete combustion of wood. Some charcoal pencils have the ochre-brown color of charcoal, which is generally black. The surface of the charcoal pencil is relatively rough and non-reflect...
