Technical Field

The invention relates to the technical field of pencil manufacturing equipment, in particular to a color-mixed pencil.

Background

The pencil is an indispensable tool in the teaching and drawing process, has the characteristics of easy erasing and easy modification, and has the important function in student study and people drawing work.

In order to obtain a better artistic expression effect or ornamental value, a color-mixed pencil is generally used by an existing artist when a sketch work is made. The existing mixed color pencils are generally monochromatic and are colored by adding pigments to the pencil preparation materials, such as pigment particles to the prepared beeswax. And the erasing effect or the smearing effect of part of the mixed-color pencil is poor, so that the mixed-color pencil is difficult to completely erase or smear.

Accordingly, there is a need for a color mixing pencil that solves one or more of the above problems.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The invention discloses a mixed color pencil, which comprises the following raw materials in parts by weight: 3-25 parts of color mica powder, 65-90 parts of graphite powder and 10-30 parts of clay, wherein the color mica powder does not comprise white mica powder and black mica powder.

The specification of the graphite powder is 100-3000 meshes, and the specification of the color mica powder is 100-3000 meshes. The more common specification is that the graphite powder and the color mica powder are in 100-800 meshes.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: the color mica powder is 5 parts, the graphite powder is 70 parts, and the clay is 10 parts or 15 parts. This embodiment achieves a pencil lead with lower hardness and lower color.

It should be noted that the colored mica powder has stable physical properties and is not easy to generate chemical reaction, so that the color particles on the drawn handwriting are independent.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: 12 parts or 14 parts of color mica powder, 65 parts, 70 parts or 75 parts of graphite powder and 10 parts, 12 parts or 15 parts of clay. This embodiment is to achieve pencil leads that are neutral in color and range in hardness from soft to hard.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: the color mica powder is any one of 14 parts, 20 parts and 24 parts, the graphite powder is any one of 70 parts, 80 parts and 90 parts, and the clay is any one of 10 parts, 15 parts, 20 parts and 25 parts. This embodiment is to obtain pencil leads with colors ranging from medium to deep and hardness ranging from soft to hard.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: the color mica powder is 14 parts, the graphite powder is 77 parts or 78 parts, and the clay is 20 parts. This embodiment is to obtain pencil leads with moderate color and hardness.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: the color mica powder is 3 parts, the graphite powder is 65 parts, and the clay is 10 parts. This embodiment is to obtain pencil leads with lower color and lower hardness.

Specifically, the mixed color pencil comprises the following raw materials in parts by weight: the color mica powder is 25 parts, the graphite powder is 90 parts, and the clay is 30 parts. The pencil lead with high color and high hardness is obtained by the embodiment.

The materials are mixed with the existing preparation materials, and the mixing and production process is the conventional technology and equipment. Such as adding talcum powder, silicon carbide, beeswax, water and ethanol solution or absolute ethanol in a certain weight ratio. The preparation process comprises the following steps: weighing the raw materials according to the proportion range for later use, mixing and grinding the weighed raw materials or mixing after grinding (the coarse grinding is generally 2000-3500 meshes), uniformly mixing the batching liquid (water, absolute ethyl alcohol, an ethanol solution with a certain weight ratio and melted beewax) and the mixed powder, carrying out defoaming treatment (vibration, shaking and ultrasonic wave) after mixing, kneading and stirring the mixture at a certain temperature (95-180 ℃), and finally carrying out drying, molding and cutting. Fine milling may also be performed at any stage prior to addition of the solution.

Specifically, the colored mica powder is uniformly mixed with the graphite powder and the clay, so that the pencil lead with uniform color distribution is obtained, and the colored mica powder is uniformly mixed with the graphite powder and the clay, so that a special artistic effect is obtained. The color of the colored mica powder at least comprises the following components: any one or more of gold, red, orange, yellow, green, cyan, blue and violet, such as: the pencil lead is produced by taking red mica powder, graphite powder and clay as raw materials and is used for drawing red and black images or characters; or lead pencil produced by using mica powder, graphite powder and clay as raw materials for drawing decorative golden edges or images.

Specifically, as shown in fig. 1, embodiment 1 in structure is also included, the graphite powder and the clay are mixed to form a first mixed layer 101, the color mica powder and the clay or the color mica powder separately form a second mixed layer 201, and the first mixed layer 101 wraps the second mixed layer 201; and second embodiment as in fig. 2, the second hybrid layer 201 wraps the first hybrid layer 101. The function is to adjust the color distribution and writing hardness distribution of the inner side and the outer side, as in the embodiment 1, the color distribution is on the inner side, and the boundary difference between the color and the black is obvious, thereby being convenient for writing and tracing; in example 2, the color is distributed on the outer side and is suitable for smearing; and the hardness is improved by composing the colored mica powder and the clay into the second mixed layer 201.

Specifically, as shown in fig. 3, the color mica powder and the graphite powder form a third mixed layer 301, and the third mixed layer 301 is wrapped by the first mixed layer 101; alternatively, as shown in fig. 4, the third mixed layer 301 surrounds the first mixed layer 101. So that the color and the black are mixed and the boundary difference is not obvious.

Specifically, as shown in fig. 5, the color mica powder, the graphite powder and the clay form a fourth mixed layer 401, the content of the mica powder in the fourth mixed layer 401 is the highest, and the fourth mixed layer 401 is wrapped by the first mixed layer 101; alternatively, as shown in fig. 6, the fourth mixed layer 401 wraps the first mixed layer 101.

In summary, the color mica powder, the graphite powder, the clay and other common ingredients are mixed in a certain proportion and different mixing modes to form the pencil lead, so that the produced pencil lead can write black and at least one color of a common pencil, and the color mica powder is adopted to enable written handwriting to be easily smeared and erased, so that the ornamental and artistic performance of the pencil is improved, for example: the expression on the color is black gold and gorgeous black, and is convenient for the use of creators. The practical value of the invention is greatly improved.
