Problems solved by technology

Existing graphite pencil cores often need overlapping colors in the painting process to express layers, depth of field, and express the artistic conception in the painting. However, due to the characteristics of graphite itself, it has gloss, and reflections occur during the color overlapping process, which affects the quality of the picture and Expression of artistic conception

Abstract

The invention discloses a matte pencil lead and a preparation method thereof and belongs to the field of matte pencil lead preparation. The invention discloses the matte pencil lead for a first time,and the matte pencil lead comprises the following components: flake graphite, amorphous graphite, clay, carbon black, talcum powder, an adhesive and water. The invention further discloses a method forpreparing the matte pencil lead. The method comprises the following steps: mixing and blending the components, kneading the mixture, grinding with three rollers, kneading the ground material for a second time, carrying out lead extrusion, drying, sintering, and soaking into oil, thereby obtaining the matte pencil lead. On the basis of a conventional graphite pencil lead, the amount of graphite isreduced, and proper amounts of carbon black and talcum powder are added, so that a glare phenomenon is effectively reduced, and the matte pencil lead has the smoothness and concentration of the conventional graphite pencil lead, and meanwhile has a color overlapping effect without glare. When a picture is drawn with the matte pencil lead, the drawing smoothness is ensured, the glare phenomenon iseffectively reduced, the picture has remarkable layering, and the picture quality and the drawing artistic conception can be improved.

Description

technical field [0001] The invention relates to a matt pencil lead, and also relates to a preparation method of the matt pencil lead, belonging to the field of preparation of matt pencil leads. Background technique [0002] Graphite pencil lead is obtained by mixing graphite, clay, binder, and water in a certain proportion, extruding the core, drying, sintering, and soaking in oil, and it can be made into a pencil for writing and drawing. Existing graphite pencil cores often need overlapping colors in the painting process to express layers, depth of field, and express the artistic conception in the painting. However, due to the characteristics of graphite itself, it has gloss, and reflections occur during the color overlapping process, which affects the quality of the picture and Expression of artistic conception. [0003] Therefore, by changing the formula of the existing graphite pencil lead, developing a new type of matte pencil lead, which not only ensures the smooth ch...
