Description

一种发泡塑料
技术领域
本发明涉及塑料领域，具体的说，本发明涉及一种发泡塑料。
背景技术
为了降低塑料产品的重量，通常的做法是在原料中添加起泡剂，使塑料中形成连续或不连续微孔型结构，从而减少了原料的使用，降低了生产原料成本和产品单重。由于起泡剂是在塑料生产过程中起反应的，微孔型结构一方面减少了重量，使得产品变得轻盈，另一方面，也破坏了原有的致密结构，降低了产品的结构强度，需要在强度方面进行改良。
发明内容
本发明的目的在于提供一种发泡塑料。
为了实现本发明的目的，本发明提供一种发泡塑料，由下列重量份的原料制成：聚碳酸酯50-150份、引发剂10-20份、发泡剂20-50份、发泡助剂10-30份和交联剂1-10份。
优选地，本发明所述的发泡塑料由下列重量份的原料制成：聚碳酸酯80份、引发剂15份、发泡剂30份、发泡助剂20份和交联剂5份。
更优选地，所述引发剂是过氧化二苯甲酰。
更优选地，所述发泡剂是偶氮二甲酰胺。
更优选地，所述发泡助剂为4-((N-(2-氟苄基)-4-(2-氟苯氧基)苯甲酰胺基)甲基)苯甲酸。
更优选地，所述交联剂是甲基丙烯酰胺。
本发明所述的发泡塑料具有优异的机械性能、耐热性能和成型加工性能，是工程结构选用的理想芯层材料。
具体实施方式
以下通过具体实施方式的描述对本发明作进一步说明，但这并非是对本发明的限制，本领域技术人员根据本发明的基本思想，可以做出各种修改或改进，但是只要不脱离本发明的基本思想，均在本发明的范围之内。
实施例1
称取聚碳酸酯80千克、过氧化二苯甲酰15千克、偶氮二甲酰胺30千克、4-((N-(2-氟苄基)-4-(2-氟苯氧基)苯甲酰胺基)甲基)苯甲酸20千克和甲基丙烯酰胺5千克，用高速搅拌机搅拌5小时，至混合物呈现酒红色，注入玻璃模具模腔中并密封，置于80℃循环水槽中反应36小时，然后置于发泡工装中，连同发泡工装一起置于电热恒温鼓风干燥箱中进行发泡，发泡温度控制在120℃，发泡时间为30min，然后分别在120℃和150℃下进行热处理3小时，即得所述发泡塑料。
实施例2
按照和实施例1相同的方式制备发泡塑料，不同之处在于不使用4-((N-(2-氟苄基)-4-(2-氟苯氧基)苯甲酰胺基)甲基)苯甲酸。
实验例
按照GB/T1040-2006测试拉伸强度，试样尺寸为150mm×20mm×板厚(8mm)，拉伸速率5mm/min。经检查，实施例1的样品的拉伸强度61.6Mpa，实施例2的样品的拉伸强度33.3Mpa，结果进行比较，差异具有统计学意义(P<0.05)。由此可见，发泡助剂的加入大大提高了产品的拉伸硬度。
