Embodiment 1

[0053] A kind of smooth writing color lead core, the batching of color lead core comprises the following components by weight: 38 parts of kaolin, 10 parts of mica powder, 25 parts of stearic acid, 8 parts of paraffin wax, 5 parts of natural beeswax, red 12 parts of pigment and 2 parts of adhesive.

Embodiment 2

[0055] A kind of smooth writing color lead core, the batching of color lead core comprises the following components by weight: 40 parts of kaolin, 8 parts of mica powder, 25 parts of stearic acid, 8 parts of paraffin wax, 5 parts of natural beeswax, red 12 parts of pigment and 2 parts of adhesive.

[0056] As can be seen through experimental testing, the color lead softness test average value in embodiment 1 is 3.65, and the smoothness test average value is 4.13, and the colored lead core softness test average value in embodiment 2 is 4.10, and the smoothness test average value is 4.10. It is 5.02, where the larger the value of softness is, the softer it is, and the larger the value of smoothness is, the smoother it is. After multiple experimental designs by the applicant, and optimization of the ratio of different components of kaolin and mica powder, experiments have proved that when the ratio of kaolin and mica powder is 5:1, the softness and smoothness of the colored lead ...

Embodiment 3

[0058] A kind of smooth writing color lead core, the batching of color lead core comprises the following components by weight: 40 parts of kaolin, 8 parts of mica powder, 25 parts of stearic acid, 5 parts of No. 56 paraffin wax, 3 parts of No. 60 paraffin wax , 5 parts of natural beeswax, 12 parts of red pigment and 2 parts of adhesive.

[0059] Compared with Example 2, the color lead softness test average value in Example 3 is 4.37, and the smoothness test average value is 5.43. According to the experimental results, it can be known that natural beeswax is compounded with two kinds of paraffin waxes with different melting points. Colored leads are softer and smoother for smoother writing.

Abstract

The embodiment of the invention discloses a colorful pencil lead writing smoothly and a preparation method of the colorful pencil lead. The colorful pencil lead writing smoothly comprises the following preparation materials in parts by weight: 40-55 parts of kaolin, 8-11 parts of mica powder, 20-25 parts of stearic acid, 6-10 parts of paraffin, 2-5 parts of natural beeswax, 5-15 parts of a pigmentand 1-3 parts of an adhesive. By adopting the preparation materials, cancerogenic substances such as talcum powder can be avoided, environmental-friendly health requirements can be met, and the smoothness, the hardness and the covering capability of the colorful pencil lead can be greatly improved.

Description

technical field [0001] The embodiments of the invention relate to the technical field of pencil manufacturing, in particular to a smooth-writing colored lead and a preparation method thereof. Background technique [0002] Colored lead is a kind of pencil lead that uses colorant as a colorant. Colored lead is mainly made of color pigments, waxes, adhesives and filling materials through mixing, grinding, and extrusion molding. It is a very widely used painting tool. The quality of colored lead is mainly divided into the following aspects: vividness of color, smoothness of writing, covering power and softness of hand feeling. Good colored pencils are bright in color, smooth to the touch, moderate in hardness and hardness, and can quickly and evenly color and draw smoothly when used on various types of paper. [0003] The inventors of the present application found that traditional colored lead cores mostly use kaolin, paraffin wax, microcrystalline wax, etc., and at the same ti...
