Production process of pearl wool for packaging boxes

The invention discloses a production process of pearl wool for packaging boxes. The production process comprises the steps that LDPE colloidal particles, a nucleating agent, an antistatic agent, colormasterbatch, talc powder and carbon black are adopted for raw material mixing; the mixture is placed and heated in a heating mechanism, and then an anti-shrinking agent is added to enable the anti-shrinking agent and the mixture to be heated and melted and mixed together; butane is used as a foaming agent to foam the mixture to be heated and extruded; and the foamed mixture is extruded out through a screw, is subjected to traction and cooling forming, and is flattened and wound to obtain a finished product. The pearl wool obtained can be anti-static, has high oxidation resistance and can be used as a raw material for production of the packaging boxes. 本发明公开了一种用于包装箱的珍珠棉生产工艺，采用LDPE胶粒、成核剂、抗静电剂、色母、滑石粉、炭黑进行原料混合；将混合料放入加热机构中加热，然后加入抗收缩剂，使得抗收缩剂和混合料加热融化混合在一起；采用丁烷做发泡剂对待加热挤出的混合料进行发泡；将发泡好的混合料通过螺杆挤出，牵引冷却成型,展平绕卷得到成品。本发明得到的珍珠棉能防
