CN106280134A 一种冰箱、冰柜用TPU弹性体门封条及其制作方法 无效 - 驳回

一种冰箱、冰柜用TPU弹性体门封条及其制作方法
摘要：
本发明公开了一种冰箱、冰柜用TPU弹性体门封条及其制作方法，门封条包括TPU弹性体门封胶套，在TPU弹性体门封胶套上穿设有磁条，构成TPU弹性体门封胶套的各原料包括：PVC、TPU、TOTM、ESO、CaCO3、TiO2、Ca/Zn稳定剂和润滑剂。本发明将TPU与PVC共混制成TPU弹性体门封条，充分结合了TPU与PVC各自的优势，利用TPU非常好的耐低温性能，使所获得的门封条在低温下硬度受温度变化影响较小，且在低温下仍有很好的回弹性，大大提高了其装配性和密封性。
摘要（英）：

The invention discloses a TPU elastomer door gasket for a refrigerator and a freezer and a production method of the TPU elastomer door gasket. The door gasket comprises a TPU elastomer door sealing rubber sleeve; a magnetic stripe is arranged on the TPU elastomer door sealing rubber sleeve in a penetrating manner. The TPU elastomer door sealing rubber sleeve is produced by using the following raw materials: PVC, TPU, TOTM, ESO, CaCO3, TiO2, a Ca/Zn stabilizer and a lubricating agent. According to the TPU elastomer door gasket and the production method thereof disclosed by the invention, the TPU and the PVC are blended to obtain the TPU elastomer door gasket, and respective advantages of the TPU and the PVC are sufficiently combined; by using excellent low temperature resistance of the TPU, the hardness of the obtained door gasket is enabled to be less influenced by temperature change at low temperature; in addition, good resilience at low temperature is still maintained, and assembling and sealing properties of the TPU elastomer door gasket are greatly improved.
