JPS5959759A - Solid painting material - Google Patents

Abstract

PURPOSE:To provide a solid painting material which requires only a small amount of a pigment and hence, has an advantage in cost, consisting of a colorant composed of a pigment and a plastic powder obtd. by dry blending them, fat and an extender. CONSTITUTION:Necessary amounts of a pigment and a plastic powder are thoroughly dry-blended at room temp. in a mixer such as a ball mill to obtain a colorant. The colorant is mixed with and dispersed in fat at a temp. at which the plastic powder does not melt, but the fat is molten. An extender is mixed with and dispersed in the mixture. The resulting mixture is charged in a mold or injection-molded. The molding is cooled and removed from the mold to obtain the desired solid material. In mixing the colorant the fat and the extender together, suitable dispersant, disintegrator, binder, etc. are added thereto to adjust the physical properties of the solid painting material, whereby the solid painting material suitable for respective applications can be obtd.

Description

[Detailed Description of the Invention] The present invention relates to a solid drawing material, and further details
This relates to a cost-effective solid drawing material that requires only a small amount of use.

Conventionally, solid drawing materials have used pigments as a coloring phase, and this pigment has a relatively high cost per solid drawing material (1). The quickest way to Mr. Kostoy-F is to reduce σ).

However, since reducing the amount of face II used will directly lead to a decrease in the color density of the solid drawing material σ), it is impossible to reduce the cost of the solid drawing material by reducing the amount of pigment used. It had been. Therefore, the present inventor was able to reduce the amount of pigment used as much as possible, and also reduced the color density by 177%.
As a result of extensive research in order to obtain a solid drawing material that does not deteriorate in taste, we have succeeded in using a colored material in which the surface of brass powder is coated with pigment, which reduces the amount of pigment used compared to conventional solid drawing materials. The present invention was completed based on the discovery that it is possible to obtain a solid drawing material that has a color density and drawing taste equivalent to that of a conventional solid one-portion drawing material with less coloring. That is, the gist of the present invention is a solid drawing material consisting of at least a colored body made of a pigment, brass, and powder obtained by dry mixing, an oil or fat, and a constitution moon.

Although it is unclear whether the solid drawing material of the present invention can achieve the same color density and drawing taste as conventional solid drawing materials despite the small amount of pigment used, it is possible to Infer. Since the colored material used in the present invention is obtained by dry mixing plastic powder and pigment, Mf-1 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, in other words, it forms a one-wall microcell with Plusdec powder as the core, the pigment's unique color development and hiding properties are not compromised. Furthermore, since it uses plastic powder as its core, the amount of pigment used can be reduced accordingly, and it is thought 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 kept small due to oil absorption of the pigment.

Next, each component used in the present invention will be explained.

Colored bodies are obtained by dry mixing pigments, plasti, and plastic powder, and from the viewpoint of color development, drawing quality, etc., the particle size of the pigment is 1.0 ltm or less, and the particle size of the plastic powder is 1.0 ltm or less.
00μ01 or less, and the mixing ratio varies depending on the particle size and specific gravity of the pigment and plastic powder, but basically the weight ratio of the pigment niblastic powder is 1 =
A ratio of 3 to 5:1 is preferred in terms of color development and drawing quality.

As the pigment, inorganic pigments such as carbon black, phosphor, titanium oxide, red iron oxide, and black iron oxide, and organic pigments such as azo, lake, and phthalonoanine pigments can be used alone or in combination.

As the plastic powder, spherical or amorphous particles such as polyvinyl chloride paratha, polyacrylic acid powder, polyethylene paratha, nylon paratha, polyester paratha, etc. 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, or 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. Can be used in combination.

As the atomizer, heavy carbonate, light carbonate, magnenium phosphate, talc, barium sulfate, etc. can be used alone or in a mixture of several amounts 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 manufacturing method of the solid-state drawn film according to the present invention will be briefly explained.

First, the required amount of pigment and plastic powder are mixed, and a colored body is obtained by thorough dry mixing at room temperature using a mixer such as a ball mill.Next, the colored body and oil are mixed so that the plastic powder does not melt. In addition, the oil and fat are mixed and dispersed at a temperature where they are melted, and the body mass is mixed therewith and sufficiently dispersed, and this is poured into or injected into a predetermined mold, cooled, and taken out from the mold. A solid drawing material is obtained.

In addition, by appropriately selecting and adding the above-mentioned dispersant, disintegrating agent, binder, etc. at the time of mixing and dispersing the colored material, oil and fat, and the bulk material, 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.
