Description

一种冰箱密封条
技术领域：
本发明涉及一种密封条，具体讲是一种冰箱密封条。
背景技术：
现有的冰箱密封条耐候性差，在天气寒冷的时候，冰箱密封条会变得很硬，从而影响密封效果。
发明内容：
本发明所要解决的技术问题是，提供一种可一直保持柔软状态，软硬适中的冰箱密封条。
本发明的技术解决方案是，提供一种冰箱密封条，以重量百分比计，由下列组分组成：
树脂45-90％，癸二酸二辛脂1-5％，偏苯三酸三辛酯15-50％，稳定剂1-3％，润滑剂0.5-1.6％，ACR树脂0.8-1.6％，填充剂1-5％。
进一步的，以重量百分比计，由下列组分组成：
树脂70％，癸二酸二辛脂3％，偏苯三酸三辛酯20％，稳定剂1％，润滑剂1％，ACR树脂1％，填充剂4％。
进一步的，稳定剂为钡锌稳定剂，润滑剂为芥酸酰胺或硅油，填充剂为石英粉。
本发明的有益效果是：添加了ACR树脂作为增韧剂，可有效提高耐候性，使得在冷热温差环境下均可保持软硬适中，冬季不会变硬。
具体实施方式：
下面结合具体实施方式对本发明作进一步说明：
一种冰箱密封条，以重量百分比计，由下列组分组成：PVC2500树脂70％，癸二酸二辛脂3％，偏苯三酸三辛酯20％，稳定剂1％，润滑剂1％，ACR树脂1％，填充剂4％，其中，稳定剂为钡锌稳定剂，润滑剂为芥酸酰胺或硅油，填充剂为石英粉。由上述组分组成的冰箱密封条，拉伸强度好，断裂伸长率可达327％，在0℃环境下硬度仅为45A左右。相比现有技术的冰箱密封条，使用寿命长，柔软性好，在不同温差环境中，可保持较好的柔软性。
