Description

[根据细则37.2由ISA制定的发明名称]　可降解无塑化胶带 技术领域
本实用新型涉及胶带及包装行业，特别是涉及一种可降解无塑化胶带。
背景技术
塑料制品的使用方便了人类生活，但由于塑料制品可降解性差，导致对环境产生了较大的污染，随着环保意识的逐渐加强，人们对塑料制品使用欲望逐渐降低。各大公司为顺应环保要求，开始采用易降解的纸胶带来替换传统的塑胶带进行包裹，但纸胶带本身耐用性差，极易被撕断，导致实用性差。为解决此问题，现有的主流纸胶带在纸层中加入塑料纤维作为加强筋，以提高纸胶带的耐用性，但此种胶带仍会带来降解性差的问题，且塑料纤维对纸胶带的耐用性提升有限，无法完全解决纸胶带耐用性差的问题。
实用新型内容
本实用新型提供了一种可降解无塑化胶带，以至少解决现有技术中纸胶带耐用性差，易撕裂的问题。
本实用新型提供了一种可降解无塑化胶带，.包括纸带层、加强层、第一黏胶层，所述加强层固定在纸带层与第一黏胶层之间，所述加强层为由可降解纤维线编织的网状结构。
进一步地，所述胶带还包括第二黏胶层，所述加强层通过第二黏胶层粘接在纸带层上。
进一步地，所述第一黏胶层选自棉纸胶或无基材胶中的一种，所述第二黏胶层选自棉纸胶或无基材胶中的一种。
更进一步地，所述可降解纤维线为棉线。
进一步地，所述加强层包括第一加强条、第二加强条，所述第一加强条、第二加强条分别位于纸带层沿着其长度方向的相对两侧。
更进一步地，所述加强层还包括中央加强条，所述中央加强条位于第一加强条、第二加强条之间。
进一步地，所述纸带层为硅油牛皮纸层。
本实用新型还提供一种上述可降解无塑化胶带的制备工艺，步骤如下：
步骤1：将第一黏胶层与加强层的一侧粘合固定；
步骤2：加强层的另一侧与纸带层粘合固定。
本实用新型还提供另一种上述可降解无塑化胶带的制备工艺，步骤如下：
步骤1：将第一黏胶层与加强层的一侧粘合固定；
步骤2：将纸带层一侧与第二黏胶层粘合；
步骤3：将加强层的另一侧与第二黏胶层粘合固定，完成胶带的制备。
本实用新型相对于现有技术，采用由可降解纤维线编织的加强层，在不影响胶带降解性能的同时，提高胶带本身的耐用性、耐撕拉性等物理性能，确保胶带在包裹运输过程中的密封性。

具体实施方式
为了使本技术领域的人员更好地理解本实用新型方案，下面将对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分的实施例，而不是全部的实施例。
本实用新型提供了一种可降解无塑化胶带，如图1所示，包括纸带层1、加强层2、第一黏胶层3，所述加强层2固定在纸带层1与第一黏胶层3之间，所述加强层2为由可降解纤维线编织的网状结构(棉布)。所述纸带层1为单侧具有硅油层11的牛皮纸。
可选的，所述胶带还包括第二黏胶层4，所述加强层2通过第二黏胶层4粘接在纸带层1上。
可选的，所述第一黏胶层选自棉纸胶或无基材胶中的一种，所述第二黏胶层选自棉纸胶或无基材胶中的一种。
特别的，所述可降解纤维线为棉线或再回收棉线。
本实用新型实施例可降解无塑化胶带的制备工艺如下：
步骤1：如图6所示，将具离型层6的第一黏胶层3与加强层2的一侧粘合固定；
步骤2：如图5所示，将纸带层1一侧与具离型层5的第二黏胶层4粘合；
步骤3：去除离型层5，使第二黏胶层4的一侧将加强层2的另一侧与第二黏胶层4粘合固定，除去具离型层6，使第一黏胶层3的一侧裸露，收卷，使纸带层1的硅油层11在卷的外侧，完成胶带的制备过程。
其中，如图2所示，本实用新型实施例1中加强层2为棉布，且加强层2与纸带层1的尺寸相近。
可选的，如图3所示，本实用新型实施例2所述加强层2包括第一加强条21、第二加强条22，所述第一加强条21、第二加强条22分别位于纸带层1沿着其长度方向的相对两侧。
其中，如图3所示，第一加强条21、第二加强条22位于纸带层1同一面的两侧，形成两条平行的加强结构。第一黏胶层、第二黏胶层均为无基材胶
特别的，如图4所示，本实用新型实施例3所述加强层2还包括中央加强条23，所述中央加强条23位于第一加强条21、第二加强条22之间。
其中，如图4所示，中央加强条23位于第一加强条21、第二加强条22之间，形成三条平行的加强结构。
本实用新型实施例1-3采用由可降解纤维线编织的加强层，在不影响胶带降解性能的同时，提高胶带本身的耐用性、耐撕拉性等物理性能，经实际的包裹试验测试，确定实施例1-3的胶带结构均具有良好的耐用性、耐撕拉性，可以满足包裹的运输要求。本实用新型实施例2、3与实施例1相比，减少加强层的面积，降低生产成本的同时仍能满足胶带的耐用性需求。此外，本实用新型实施例1-3中的棉纤维可采用回收的棉纤维结构，进一步降低生产成本，提高本实用新型实施例胶带的实用性。
最后应当说明的是，以上实施例仅用以说明本实用新型的技术方案而非对其限制，尽管参照上述实施例对本实用新型进行了详细的说明，所属领域的普通技术人员应当理解，技术人员阅读本申请说明书后依然可以对本实用新型的具体实施方式进行修改或者等同替换，但这些修改或变更均未脱离本实用新型申请待批权利要求保护范围之内。
