Description

一种包装材料用发泡材料
技术领域
本发明属于材料科学技术领域，尤其涉及一种包装材料用发泡材料。
背景技术
目前发泡材料大多采用EVA(乙烯-醋酸乙烯共聚物)为基础材料，但是以EVA为基础的发泡材料产品耐老化性能、耐屈挠性能、弹性和耐磨性较差，且EVA发泡材料的填充能力有限。
PP(偶氮二甲酰胺)是一种半结晶的热塑性塑料，具有较高的耐冲击性，机械性质强韧，抗 多种有机溶剂和酸碱腐蚀，但是PP材料具有低温脆性的缺点，且硬度较低，成型收缩率大。 目前对PP材料硬度和韧性的改进点主要由以下三点：一、在PP材料中添加CaCO3，为了进一 步改进CaCO3的添加效果，将添加的CaCO3粒径控制在纳米级；二、将PP为基础材料替换为EPM (乙烯-丙烯共聚物)、乙烯-丙烯-二烯烃三元共聚物(EPDM)或聚乙烯辛烯共弹性体(POE)等 弹性体作为改进材料；三、如CN201310746830公开了在发泡材料中添加微球型发泡剂，改善 发泡效果。但是上述的两点改进依然无法克服PP材料或者其替代材料发泡性能差，在发泡 过程中聚合物断裂的问题，故上述改进的材料依然无法替代EVA产品。
发明内容

一种包装材料用发泡材料，其原料及原料重量百分含量如下：
丙烯乙烯共聚物 40-50％；
氢化蓖麻油0.1-1％；
聚苯乙烯树脂0.1-3％；
透明质酸0.1-3％；
甲基丙烯酸乙酯0.1-3％；
偶氮二甲酰胺 40-60％。
本发明具有弹性强、韧性好、使用寿命长的特点。
具体实施方式
下面将结合具体实施例来详细说明本发明，在此本发明的示意性实施例以及说明用来解释本发明，但并不作为对本发明的限定。
实施例
本发明所述一种包装材料用发泡材料，其原料及原料重量百分含量如下：丙烯乙烯共聚物 45％、氢化蓖麻油0.5％、聚苯乙烯树脂0.5％、透明质酸1％、甲基丙烯酸乙酯2％、偶氮二甲酰胺 51％。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
