一种环保型木塑料铅笔笔杆及其生产方法
摘要：
本发明公开了一种塑料铅笔笔杆，其中笔杆料包括：复合稳定剂、PVC树脂、植物粉(如木粉、竹粉、玉米杆粉、麦杆粉等)、润滑剂(外)、润滑剂(内)、环保增塑剂、腊、硬脂酸、橡胶、ACR、工程塑料(ABS)、AC发刨剂、成型调节剂、石墨。其重量配比为：复合稳定剂0.5％-10％、PVC树脂10％-50％、植物粉(如木粉、竹粉、玉米杆粉、麦杆粉等)10％-80％、润滑剂(外)1％-10％、润滑剂(内)1％-10％、环保增塑剂1％-10％、腊1％-10％、硬脂酸1％-10％、橡胶1％-10％、ACR1％-10％、工程塑料(ABS)1％-15％、AC发刨剂1％-10％、成型调节剂5％-15％、石墨5％-25％。本发明外形与木制铅笔相同，书写流利、光滑，切削、卷削容易，字迹易擦，价格低于木制铅笔，可节约大量木材。
摘要（英）：

The invention discloses a plastic pencil arm, wherein the pencil arm comprises a composite stabilizer, PVC resin, plant powder (such as wood powder, bamboo powder, corn stalk powder, straw powder, and the like), an lubricant (for external use), an lubricant (for internal use), an environment-friendly plasticizer, wax, stearic acid, rubber, ACR, engineering plastics (ABS), an AC foamer, a molding modifier, and graphite. The weight percents are: 0.5%-10% of the composite stabilizer, 10%-50% of PVC resin, 10%-80% of plant powder (such as wood powder, bamboo powder, corn stalk powder, straw powder, and the like), 1%-10% of the lubricant (for external use), 1%-10% of the lubricant (for internal use), 1%-10% of the environment-friendly plasticizer, 1%-10% of wax, 1%-10% of stearic acid, 1%-10% of rubber, 1%-10% of ACR, 1%-15% of engineering plastics (ABS), 1%-10% of the AC foamer, 5%-15% of the molding modifier, and 5%-25% of graphite. The pencil arm of the invention has a profile being the same as that of a wood pencil, can realize fluent and smooth writing, easy cutting and roll-cutting, easily erasable handwriting, lower price than wood pencils, and thus can save a lot of wood.
