Abstract

本发明涉及聚丙烯发泡复合技术。针对现有技术其工艺复杂，所使用聚氯乙烯是不可降解材料，对环境有一定污染，而热性差、生产成本高等不足之处，而提出一种制造方法简单，符合环保要求的可降解、物理耐热性高、成本低的聚丙烯发泡片材与无纺布复合制造方法。所采用技术方案是：将聚丙烯发泡料投入挤塑机的料斗内，将挤塑机的温度升到100℃-300℃，使聚丙烯发泡料熔炼，启动挤塑机的螺杆旋转，使熔炼的聚丙烯发泡料从机内向100℃-280℃的T型头口模挤出，挤出已发泡的聚丙烯发泡料流向挤板机组两辊筒缝楔中去，经辊压成片状材，自然冷却到60℃-130℃时，与无纺布的布头同时进入另一个两辊筒缝楔中去，经三辊压成复合片状材，自然冷却到实温后，按需要切成一定规格片材，即成成品。

Description

聚丙烯发泡片材与无纺布复合制造方法
一、技术领域
本发明涉及一种复合制造方法，特别是涉及一种聚丙烯发泡片材与无纺布复合制造方法。
二、背景技术
在专利申请号为200310113241.9，公开了“一种聚氯乙烯发泡卷材垫板的制造方法”专利技术，所采用的工艺复杂，使用聚氯乙烯是一种不可降解的化工材料，对环境有一定污染，在物理耐热性差，只有65℃，不能做100℃以上热变形温度的产品，其生产成本较高等不足之处。而采用聚氨脂材料的仍然存在上述不足之处。
三、发明内容
本发明的目的是提供一种制造方法简单，符合环保要求的可降解、物理耐热性高、生产成本低的聚丙烯发泡片材与无纺布复合制造方法。
本发明的目的所采用技术方案是，其制造方法步骤如下：
含有均聚聚丙烯、碳酸硅、AC发泡剂，按重量比分别为70-80、10-20、10-15的聚丙烯发泡料，投入挤塑机的料斗内，将挤塑机的温度升到100℃-280℃，使聚丙烯发泡料熔炼，启动挤塑机的螺杆旋转，使熔炼的聚丙烯发泡料从机内向100℃-280℃的T型头口模挤出，挤出已发泡的聚丙烯发泡料流向挤板机组的两辊筒缝楔中去，经辊压成片状材，自然冷却到60℃-130℃时，与无纺布的布头同时进入另一个两辊筒缝楔中去，经三辊压成复合片状材，自然冷却到室温后，按需要切成一定规格片材，即成成品。
本发明，挤塑机采用单螺杆。
本发明，挤塑机采用双螺杆。
本发明制造方法简单，操作简便，所生产的片材经无纺布装饰美观大方，质轻、隔热、隔音、缓冲、比强度高、成本低，且具有降解性能，利於环保的聚丙烯发泡片材。可广泛地作为包装、热绝缘、汽车摩托车零部件、建筑等领域材料使用。
四、具体实施方式
下面结合实施例进一步说明本发明。
含有均聚丙烯、碳酸硅、AC发泡剂偶氮二甲酰胺，按重量比分别为80、10、10的聚丙烯发泡料，投入Φ90挤塑机的料斗内，将Φ90挤塑机的温度升到100℃，使聚丙烯发泡料熔炼，启动Φ90挤塑机的双螺杆旋转，使熔炼的聚丙烯发泡料从机内向100℃的T型头口模挤出，挤出已发泡的聚丙烯发泡料流向挤板机组的两辊筒2mm缝楔中去，经辊压成片状材，自然冷却到130℃时，与厚度为1.2mm的聚酯无纺布的布头同时进入另一个两辊筒缝楔中去，经三辊压成复合片状材，自然冷却，切成1.5米x1米规格，即成聚丙烯发泡片材与无纺布复合成品。
