Problems solved by technology

The main part of the production of these pens is the pen body structure. Most of the pen body structures produced now are made of plastic materials. Although there are currently PVC materials or other organic materials that replace some wood, PVC materials have many additives, such as plasticizers. Stabilizers, lubricants, etc., are very unhealthy;
[0003] At present, the age of using ballpoint pens or gel pens is getting younger and younger. Children will inevitably bite and lick with their teeth when using them, which poses a great safety hazard;
[0004] In addition, once the plastic pen body is discarded, it is difficult to degrade. If it is incinerated, it will release polluting gas, damage the environment, and bring secondary pollution to the environment.

Abstract

The invention belongs to the technical field of chemical synthesis, and particularly relates to a pen body for wood-plastic gel pens or ball pens. The pen body for wood-plastic gel pens or ball pens is prepared from the following raw materials in percentage by weight: 30-45% of wood meal, 20-30% of starch, 20-30% of resin, 5-8% of foaming agent, 0.1-1% of antioxidant, 0.5-2% of coupling agent and 0.1-2% of silicone powder. The material provided by the invention is nontoxic and harmless in deed, can not influence good health of children, considers the health and safety of children in deed, and takes responsibility for the next generation. Besides, the prepared product has favorable performance.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a pen body for a wood-plastic neutral pen or a ballpoint pen. Background technique [0002] At present, China produces about tens of billions of gel pens or ballpoint pens every year, and is the largest producer and exporter of gel pens and ballpoint pens in the world. The main part of the production of these pens is the pen body structure. Most of the pen body structures produced now are made of plastic materials. Although there are currently PVC materials or other organic materials that replace some wood, PVC materials have many additives, such as plasticizers. Stabilizers, lubricants, etc., are very unhealthy; [0003] At present, the age of using ballpoint pens or gel pens is getting younger and younger. Children will inevitably bite and lick with their teeth when using them, which poses a great safety hazard; [0004] In addition, once the plastic pe...
