Abstract

本发明涉及一种制造铅笔杆的方法,将石膏加废纸纤维和粘合剂及适量缓凝剂搅拌,制成稀料,将稀料注入模具,制成坯料,将坯料干燥后,加入铅芯制成铅笔,将铅笔浸入石蜡中处理。用本发明提供的方法制造铅笔杆,不使用木材、制成的笔杆切削容易、造价低廉,本发明可广泛用于铅笔制造行业。

Description

一种制造铅笔杆的方法
本发明涉及一种铅笔的制造方法,具体说是一种铅笔杆的制造方法。目前,所用的铅笔杆多为木材加工制成,这种方法既浪费绿色资源,又与环保不利,且制造成本高。
本发明的目的就是克服现有制造铅笔杆方法的不足,提供一种制造不使用木材、切削容易、且造价低廉的铅笔杆的方法。
为达到上述目的,一种制造铅笔杆的方法,其特征是该方法包含以下步骤:将2-8.5份石膏(按重量比,下同)加1.5-8份废纸纤维和8-20份粘合剂及适量缓凝剂搅拌,制成稀料,将稀料注入模具,制成坯料,将坯料干燥后,加入铅芯制成铅笔,将铅笔浸入石蜡中处理。
本发明所用粘合剂是将5%-25%的淀粉水溶液升温糊化制成,纤维采用纸粉碎成细小均匀的纸纤维,所用石蜡为石蜡熔液或液体石蜡。
本发明所用该粘合剂使稀料在模具中具有良好的可塑性,加入按规定所述比例的石膏使制成品成型尺寸精确,加入按规定所述比例的纤维可改善制成品的力学结构。
下面对本发明做详细说明。
实施例1、配制5%的淀粉水溶液,升温糊化成粘合剂备用。按2克石膏加8克废纸纤维,废纸纤维为干重,再加20克淀粉粘合剂及适量缓凝剂搅拌制成稀料,将稀料注入模具,制成铅笔杆坯料,将坯料干燥后,加入铅芯制成铅笔,将铅笔浸入石蜡中处理。
实施例2、配制10%的淀粉水溶液,升温糊化成粘合剂备用。按6克石膏加4克废纸纤维,废纸纤维为干重,再加10克淀粉粘合剂及适量缓凝剂搅拌制成稀料,将稀料注入模具,制成铅笔杆坯料,将坯料干燥后,加入铅芯制成铅笔,将铅笔浸入石蜡中处理。
实施例3、配制25%的淀粉水溶液,升温糊化成粘合剂备用。按8.5克石膏加1.5克废纸纤维,废纸纤维为干重,再加8克淀粉粘合剂及适量缓凝剂搅拌制成稀料,将稀料注入模具,制成铅笔杆坯料,将坯料干燥后,加入铅芯制成铅笔,将铅笔浸入石蜡中处理。
