Description

环保纸杯淋膜纸
技术领域
本实用新型属于复合纸领域，主要涉及一种环保纸杯淋膜纸。
背景技术
纸杯是人们饮水常用的饮具。由于纸杯直接用于餐饮存在耐水、耐油和阻隔性的问题，一般采用表面涂层的方法解决。目前纸杯广为使用的纸质材料为表面涂聚乙烯淋膜纸。
把聚乙烯（通常所说的PE颗粒原料）经过高温变成液态流状胶水，通过专业滚筒设备涂布在纸的表面，经过冷却设备处理后，流状聚乙烯均匀牢固地和纸复合在一起，称为淋膜纸；覆盖在纸面的PE（聚乙烯）材料具有良好拉伸韧性，因此膜面具有保护产品不受划伤的功能；膜面经水测试，不透气，不透水，具有很好的防潮作用，适宜于制造成袋装纸杯。
但是由聚乙烯淋膜纸生产的纸杯，在餐饮使用结束废弃后，其进入垃圾或环境系统后，表面淋膜层聚乙烯塑料不易降解，表现为其不可用堆肥化方式处理或自然条件下降解，影响了垃圾的堆肥化推广应用，造成了环境污染。由于其在日常生活中用量相对较大，构成的环境影响深受人们的关注。特别是随着我国城镇化的快速发展，生活垃圾堆肥化处理越来越多，环保型纸杯材料的开发受到重视。
聚丁二酸丁二醇酯（PBS）于20世纪90年代进入材料研究领域，并迅速成为可广泛推广应用的通用型生物降解塑料研究热点之一。PBS力学性能优异，耐热性能好，热变形温度和制品使用温度可以超过100℃。其合成原料来源既可以是石油资源，也可以通过生物资源发酵得到，PBS是目前世界公认的综合性能最好的生物降解塑料。可用于包装、餐具、化妆品瓶及药品瓶、一次性医疗用品、农用薄膜、农药及化肥缓释材料、生物医用高分子材料等领域。
发明内容
为了克服上述缺陷，本实用新型提供了一种环保纸杯淋膜纸，该新结构淋膜纸的原纸层和环保淋膜层。
本实用新型为了解决其技术问题所采用的技术方案是：
一种环保纸杯淋膜纸，具有原纸层和聚丁二酸丁二醇酯淋膜层，所述聚丁二酸丁二醇酯淋膜层的厚度为10μm(重量一般在10克每平方米)。
所述环保纸杯淋膜纸可以是下述结构：所述原纸层具有相对的两个表面，所述聚丁二酸丁二醇酯淋膜层位于所述原纸层的一个表面上。
本实用新型的有益效果是：都可全生物降解，环保卫生，为后续使用完毕后进行垃圾系统堆肥处理提供保证，解决了纸杯对环境的影响与破坏。
附图说明
图1为本实用新型实施例1所述环保纸杯淋膜纸的结构示意图。
具体实施方式
实施例1：一种环保纸杯淋膜纸，如图1所示，原纸层1具有相对的两个表面，聚丁二酸丁二醇酯淋膜层2粘接所述原纸层1的一个表面上。
其中，所述聚丁二酸丁二醇酯淋膜层的厚度为10μm(重量一般在10克每平方米)，所述原纸层可以是各种规格的化学木浆制成的原纸（白纸板）等。
