Abstract

The invention discloses an environment-friendly non-toxic pencil barrel and relates to the technical field of preparation of school supplies. The environment-friendly non-toxic pencil barrel is made from raw materials comprising, by weight, 60-80 parts of twigs, 3-5 parts of hydrogen peroxide, 6-8 parts of ultramarine, 5-7 parts of paraffin, 10-20 parts of calcium carbonate, 8-10 parts of dibutyl ester, 3-5 parts of a foaming agent, 6-8 parts of a curing agent and 80-100 parts of care soaking liquid. The environment-friendly non-toxic pencil barrel has the advantages of being concise in technological process and reasonable in raw material proportion; the main raw materials are subjected to treatment by natural sterilization liquid which is non-toxic and functions in sterilization and disinfection, so that the pencil barrel is healthy in component, non-toxic and harmless, remarkable in use effect and convenient to promote and use.

Description

technical field [0001] The invention relates to the technical field of school supplies preparation, in particular to an environment-friendly non-toxic pencil holder and a preparation method thereof. Background technique [0002] Pencil is the main utensil used for art drawing and drawing, and it is also one of the commonly used learning utensils for students. Pencil is mainly composed of pencil shaft and pencil core. The materials of pencil shaft mainly include wood and glue, and wood is used to make Pen holders require upright texture, fine and uniform structure, soft or slightly soft, slightly brittle, less resin, low hygroscopicity, small expansion and contraction, and no deformation. There are mainly pencil cedar (red cedar), cedar, sida, basswood, alder, etc. The adhesive should have appropriate viscosity, fluidity and wettability. After hardening, the adhesive layer has toughness, which has little damage to the tool and has Certain water resistance, heat resistance, a...
