Abstract

本发明公开了一种PET膜和PU膜的复合方法，包括以下步骤，步骤一，沿着复合辊方向分别运行PU膜和PET膜，并在靠近复合辊的位置对PU膜进行加热，加热温度为60‑150℃，PU膜和PET膜的运行速度为20‑50m/s；步骤二，使PU膜和PET膜通过复合辊进行复合压实。该PET膜和PU膜的复合方法使得PU膜和PET膜可以直接复合，无需粘胶层，扩大了应用范围，同时复合效果好，不易产生缩皱，气泡等问题。

Description

一种PET膜和PU膜的复合方法及应用
技术领域：
本发明涉及医疗用品领域，具体是一种PET膜和PU膜的复合方法及应用。
背景技术：
PET膜又名耐高温聚酯薄膜，它具有优异的物理性能、化学性能及尺寸pet膜稳定性、透明性、可回收性，可广泛的应用于磁记录、感光材料、电子、电气绝缘、工业用膜、包装装饰等领域；PU膜即为聚氨酯薄膜，是一种无毒无害的环保材料，对人体皮肤无任何伤害，并广泛应用于服装面料、医疗卫生、皮革等领域。医疗领域种，PU膜常作为防水层使用，而PET膜长作为粘胶层隔离膜使用，但PU膜上涂布夹层，与PET膜复合时容易起皱，气泡，对生产工艺要求极高，良品率一直不是很理想，而且粘胶层在使用时对皮肤有诸多限制。
发明内容：
本发明所要解决的技术问题是，提供一种方便复合的PET膜和PU膜的复合方法。
本发明的技术解决方案是，提供一种PET膜和PU膜的复合方法，包括以下步骤，
步骤一，沿着复合辊方向分别运行PU膜和PET膜，并在靠近复合辊的位置对PU膜进行加热，加热温度为60-150℃，PU膜和PET膜的运行速度为20-50m/s；
步骤二，使PU膜和PET膜通过复合辊进行复合压实。
本发明提供的另一技术方案是，提供一种PET膜和PU膜的应用，热合的PET膜和PU膜应用于防水伤口敷料和婴儿护脐贴。
采用以上工艺后与现有技术相比，本发明具有以下优点：本工艺使得PU膜和PET膜可以直接复合，无需粘胶层，扩大了应用范围，同时复合效果好，不易产生缩皱，气泡等问题。
具体实施方式：
下面就具体实施方式对本发明作进一步说明：
一种PET膜和PU膜的复合方法，包括以下步骤，
步骤一，沿着复合辊方向分别运行PU膜和PET膜，并在靠近复合辊的位置对PU膜进行加热，加热温度为60-150℃，PU膜和PET膜的运行速度为20-50m/s；较佳的，加热温度为90℃，运行速度为35m/s，
步骤二，使PU膜和PET膜通过复合辊进行复合压实。
本工艺热合的PET膜和PU膜可应用于防水伤口敷料和婴儿护脐贴。
本工艺使得PU膜和PET膜可以直接复合，无需粘胶层，扩大了应用范围，同时复合效果好，不易产生缩皱，气泡等问题。
以上仅就本发明较佳的实施例作了说明，但不能理解为是对权利要求的限制。凡是利用本发明说明书所做的等效结构或等效流程变换，均包括在本发明的专利保护范围之内。
