The present invention relates to a solid drawing material, and more particularly to a cost-effective solid drawing material that requires only a small amount of pigment. Pigments have traditionally been used as coloring agents in solid drawing materials, and this pigment is relatively expensive in the composition of solid drawing materials, so reducing the amount of pigment used is the quickest way to lower costs. It is. However, since reducing the amount of pigment used directly leads to a decrease in the color density of the solid drawing material, it has been considered impossible to reduce the cost of the solid drawing material by reducing the amount of pigment used. Therefore, the inventor of the present invention has conducted extensive research in order to obtain a solid drawing material that can reduce the amount of pigment used as much as possible and that does not reduce the coloring density or the drawing quality. It has been discovered that by using a solid drawing material, it is possible to obtain a solid drawing material that uses less pigment than conventional solid drawing materials and has the same coloring density and drawing taste as conventional solid drawing materials, and has developed the present invention. It is completed. That is, the gist of the present invention is a solid drawing material comprising at least a colored body having a pigment fixed on the surface of plastic powder obtained by dry mixing, an oil or fat, and an extender. Although it is not clear why the solid drawing material of the present invention can achieve the same color density and drawing taste as conventional solid drawing materials despite using a small amount of pigment, it is speculated as follows. do. Since the colored material used in the present invention is obtained by dry mixing plastic powder and pigment, the pigment particles adhere physically or electrostatically to the surface of the plastic powder, causing the plastic powder to adhere to the surface of the plastic powder. Because the pigment covers the surface of the body, that is, it forms pigment wall microcapsules with plastic powder as the core.
Without impairing the pigment's unique color development and hiding properties,
Furthermore, since it uses plastic powder as its core, the amount of pigment used can be reduced accordingly, and it seems that there will be no deterioration in the drawing quality. The present invention is particularly effective when the pigment used is expensive or when the amount of pigment used must be reduced due to the oil absorption of the pigment. Next, each component used in the present invention will be explained. The colored body is obtained by dry mixing the pigment and plastic powder, and from the viewpoint of color development, drawing quality, etc., it is desirable that the particle size of the pigment is 1.0 μm or less, and the particle size of the plastic powder is 100 μm or less.
The mixing ratio also varies depending on the particle size and specific gravity of the pigment and plastic powder, but in general, a mixture with a pigment:plastic powder weight ratio of 1:3 to 5:1 will produce the best color. , preferred in terms of drawing quality. Pigments include carbon black, titanium oxide,
Inorganic pigments such as red iron oxide and black iron oxide, and organic pigments such as azo pigments, lake pigments, and phthalocyanine pigments can be used alone or in combination. As the plastic powder, polyvinyl chloride powder, polyacrylic acid powder, polyethylene powder, nylon powder, polyester powder, and other spherical or irregularly shaped plastic powders can be used singly or in combination. The oil may be any oil that does not have an adverse effect on the plastic powder and pigments, and animal/plant-based or mineral-based waxes that are solid at room temperature, animal/vegetable-based or mineral-based liquid oils that are liquid at room temperature may be used singly or in combination depending on the purpose. It can be used as As the extender material, heavy calcium carbonate, light calcium carbonate, magnesium phosphate, talc, barium sulfate, etc. can be used alone or in combination depending on the purpose. In addition to the components shown above, a dispersant, a disintegrating agent, a binder, etc. can also be used as appropriate depending on the purpose. Next, the method for manufacturing the solid drawing material of the present invention will be briefly explained. First, pigment and plastic powder are blended in required amounts and thoroughly dry-mixed at room temperature using a mixer such as a ball mill to obtain a colored body. Next, the colored body and fat are mixed and dispersed at a temperature at which the plastic powder does not melt and the fat melts, and an extender is mixed with this and sufficiently dispersed, and this is poured into a predetermined mold.
Alternatively, the solid drawing material of the present invention can be obtained by injection, cooling, and removal from the mold. In addition, by appropriately selecting and adding the above-mentioned dispersant, demolition agent, binder, etc. at the time of mixing and dispersing the colored body, oil and fat, and extender, the physical properties of the solid drawing material can be adjusted and the solid material suitable for the application can be obtained. You can get drawing materials. The present invention will be described in more detail below with reference to Examples. In addition, "parts" in the examples indicate "parts by weight."
