Description

一种发泡母料、其制备方法及应用
技术领域
本发明属于发泡技术领域，具体涉及一种发泡母料、其制备方法及应用。
背景技术
在塑料加工领域，为减轻塑料的重量，增强材料的隔热性能、隔音性能以及防震性能，或者实现材料的某种外观设计，通常在塑料中添加发泡剂，经过发泡工艺，使材料内部形成许多细小泡孔，应用十分广泛。
目前使用化学发泡剂的发泡塑料在生产中主要有两种形式：一种直接使用发泡剂，易造成粉尘飞扬，存在安全隐患和危害环境。一种是使用发泡母粒。发泡母粒是将超量发泡剂、与分散剂、发泡助剂和树脂载体等混合,经过塑炼拉片切粒或挤出造粒而成，发泡母粒使发泡塑料的生产更为环保简单。然而发泡母粒的加工和使用过程仍旧存在问题。一是发泡母粒需要将树脂载体、发泡剂、分散剂、发泡助剂等混合在一起，经高速捏合、塑炼拉片切粒或挤出机塑炼切粒而成，工序繁琐、能耗高，且混料过程会造成粉尘污染。二是发泡剂高温易分解的特性也限制了发泡母粒的塑炼或挤出工艺，如果加工工艺控制不当造成发泡剂分解，极易造成产品废弃甚至生产安全问题。三是在发泡塑料生产时，发泡母粒以一定比例加入到基体树脂粒料或粉料中，物料之间的混合不均匀会造成发泡剂分散不均，易造成发泡塑料泡孔不均匀等问题。

本发明还提供一种上述的发泡母料的制备方法，包括如下步骤：将原料加入容器中，以500r/min-3000r/min的转速研磨分散均匀。
在研磨过程中，会产生热量，可以用冷却水在研磨容器外进行冷却，以控制原料的温度不会过高，例如控制温度不高于60℃。当然，也可以采用其他方法进行冷却，保证原料的温度不会过高。
研磨分散时间可以是20min-60min。
本发明还提供一种发泡母料在注塑、挤出发泡塑料的应用。
具体地，该发泡母料可用于以下发泡材料的制备：聚乙烯(PE)、聚丙烯(PP)、聚氯乙烯(PVC)、乙烯-乙酸乙烯酯共聚物(EVA)、热塑性橡胶(TPR)、聚苯乙烯(PS)、丙烯睛-丁二烯-苯乙烯共聚物(ABS)及聚碳酸酯(PC)的发泡加工。
一实施例中，发泡母料与发泡材料的质量比为0.5-6：100。采用该质量比例，可以较好地实现发泡效果，而用量又不会过多而造成浪费。
