Description

一种淋膜无纺布的淋膜配方
技术领域
本发明涉及一种淋膜无纺布，具体是指一种淋膜无纺布的淋膜配方。
背景技术
目前无纺布袋大多采用覆膜无纺布，其是用干式覆膜机将胶水涂在印好的各种膜上经过烘干后,再与无纺布一起经复合热压滚筒挤压后压纹制袋而成。覆膜无纺布存在以下一些缺点：1)覆膜无纺布胶水粘合牢度差,容易起层，使用寿命最长只为6个月；2)覆膜无纺布的胶水中含有甲苯和乙脂等化学溶剂,容易造成印刷品变黄,变暗,图像模糊等质量问题,从而造成很大的浪费；3)覆膜无纺布摸上去表面光滑,柔软无质感和立体感。目前出现有性能优于覆膜无纺布的淋膜无纺布，然而目前淋膜无纺布的淋膜材料选择局限，通常只采用聚乙烯作为淋膜层，所得的淋膜无纺布不够坚挺、坚韧及牢固，由此影响淋膜无纺布产品的品质。
发明内容
本发明的目的在于提供一种淋膜无纺布的淋膜配方，带来提升淋膜无纺布产品坚挺、坚韧、牢固及美观的优良品质。
为了达成上述目的，本发明的解决方案是：
一种淋膜无纺布的淋膜配方，由聚丙烯涂覆料、高压聚乙烯及填充母料组成。
所述淋膜无纺布所采用的塑料膜为镀铝膜或者OPP膜，所述淋膜配方中，聚丙烯涂覆料:高压聚乙烯:填充母料的重量比为70:25:5。
所述淋膜无纺布所采用的塑料膜为金膜或者PET膜，所述淋膜配方中，聚丙烯涂覆料:高压聚乙烯:填充母料的重量比为25:70:5。
采用上述方案后，本发明相对于现有技术的有益效果在于：本发明淋膜无纺布的淋膜配方由聚丙烯涂覆料、高压聚乙烯及填充母料组成，其中聚丙烯涂覆料无毒、无臭、无味，具有良好的透明度,低温热封性能,与无纺布和塑料薄膜有良好的粘合强度；高压聚乙烯无毒、无臭、无味，具有良好的低温热封性能,优良的加工性,极好的粘合强度,并且能够提高聚丙烯的熔体强度,降低颈缩,改善涂膜料的成膜性能；填充母料为有机过氧化物,可以使聚丙烯断链,发生化分降解,使熔融指数增大，在填充母料、聚丙烯涂覆熔冶，及高压聚乙烯的共混挤出过程中,发生聚丙烯的降解反应,聚乙烯的交联反应,以及聚丙烯和聚乙烯的接枝反应，填充母料的增加还可以更好地加速反应,由此使所得的淋膜无纺布产品具有坚挺、坚韧、牢固及美观的优良品质。
具体实施方式
下面结合具体实施方式对本案作进一步详细的说明。
本发明一种淋膜无纺布的淋膜配方，由聚丙烯涂覆料、高压聚乙烯及填充母料组成。
聚丙烯涂覆料:其分子式为C3H6nCAS，无毒,无臭,无味(符合环保要求)，具有良好的透明度,低温热封性能,更好的刚性,与无纺布和塑料薄膜有良好的粘合强度；具体性能如下：
基本性能      熔体流动速率  ASTM   D—1238   20g/10min
              密度    ASTM   D—792    0.9g/立方厘米
机械性能      断裂拉伸强度   ASTM   D—638   300kg/平方厘米
              断裂伸长率      ASTM   D—638   800％
热性能           熔点         TPC方法    136度
其它性能      刚性      ASTM    D—747  8100kg/平方厘米
高压聚乙烯：又称低密度聚乙烯,其分子式为nCH2＝nCH2→--[CH2—CH2]n--,无毒,无臭,无味(符合环保要求)，具有良好的低温热封性能,优良的加工性,极好的粘合强度,提高聚丙烯的熔体强度,降低颈缩,改善涂膜料的成膜性能；具体性能如下：
基本性能      熔体流动速率      7.0g/10min
             密度                         0.92g/立方厘米
机械性能      断裂拉伸强度      15kg/平方厘米
断裂伸长率           2500％
热性能             TPC方法      92度
填充母料：为有机过氧化物,可以使聚丙烯断链,发生化分降解,使熔融指数增大，在填充母料、聚丙烯涂覆熔冶，及高压聚乙烯的共混挤出过程中,发生聚丙烯的降解反应,聚乙烯的交联反应,以及聚丙烯和聚乙烯的接枝反应，填充母料的增加还可以更好地加速反应。
由于无纺布所采用塑料膜的种类很多,不同种类的材质性能不一样,所以针对不同的材质,需要采用不同的淋膜配方比例，下面列举两个具体实施例。
实施例一
针对镀铝膜+无纺布，或者OPP膜+无纺布，所采用的淋膜配方重量比如下:
聚丙烯涂覆料:高压聚乙烯:填充母料
        70    :         25         :    5
实施例二
针对金膜+无纺布，或者PET膜+无纺布，所采用的淋膜配方重量比如下:
聚丙烯涂覆料:高压聚乙烯:填充母料
      25           :         70         :    5
在生产过程中,视实际粘合强度,可适当调整聚丙烯涂覆料,高压聚乙烯,填充母料的配比比例，如需要增加粘合强度,可提高高压聚乙烯的比例,同时降低聚丙烯涂覆料和填充母料的比例；如需要降低粘合强度,则提高聚丙烯涂覆料和填充母料的比例,同时降低高压聚乙烯的比例。
以上所述仅为本发明的优选实施例，凡跟本发明权利要求范围所做的均等变化和修饰，均应属于本发明权利要求的范围。
