Description

一种无纺布餐台垫的生产工艺
技术领域
本发明涉及餐厨用品的生产方法，特别是一种无纺布餐台垫的生产工艺。
背景技术
现有的餐台垫的中间层一般由通用的PP+PE塑料通过挤出机(也称押出机)熔融共挤压片而成，由于其中间层的材料成分所致，仅由PP+PE塑料组成，成品较为轻，且成本较高，由于上述材料薄而且透明，造成上下两面的图案互相影响，以致显得整体画面不清晰，杂乱无章。更重要的一点是，由于材料薄轻，在使用过程中，餐台垫铺在桌面上以后，往往容易翻卷、扭曲，甚至移位，给使用带来诸多不便。因此，需要对餐台垫的生产方法进行重新设计和改进。
发明内容
为了克服现有技术的不足，本发明的目的在于提供一种材料厚实、上面图案清晰、下面无图案无需遮盖、不易翻卷、扭曲或者移位的无纺布餐台垫的生产工艺。
本发明解决其技术问题所采用的技术方案是：一种无纺布餐台垫的生产工艺，包括以下步骤：
第一步、配料，将以下原料颗粒按各自的重量比配成混合料：PE704240％、PPT30s10％、重质碳酸钙36％、PE蜡9％、硬酯酸锌3％、偶联剂2％；
第二步、混料，将第一步获得的混合料在高速搅拌机内运转搅拌均匀；
第三步、熔融挤出，将第二步已混合均匀的混合料送进熔融挤出机，并将熔融挤出机渐进控温至处于170-220度摄氏温度下，使所述混合料熔融挤出并且拉成片；
第四步、淋复定型，将第三步获得的拉片通过定型冷却辊筒，并且在拉片的前面垫上BOPP印刷花膜，后面垫上无纺布，这样三层经过定型冷却辊筒挤出定型，再收卷成为成品。
优选的，所述偶联剂为固体钛酸酯颗粒。
本发明的有益效果是：由于所述混合料中含有重质碳酸钙、PE蜡、硬酯酸锌等组成成分，使得本发明方法生产的餐台垫的中间层变得厚实，这样，餐台垫的上面的图案非常清晰明朗，而餐台垫的下面为无纺布，本身无图安，所以不需要遮盖，省去了钛白粉粉成分，而且本发明方法生产的餐台垫也会不易翻卷、扭曲，不易移位。同时，本发明所使用的材料卫生、无毒、易分解，可回收利用，更环保，而且，采用无纺布为底层，增加了餐台垫的韧性。
附图说明
下面结合附图和实施方式对本发明作进一步说明。
图1是本发明的工艺流程方框图。
具体实施方式
参照图1，本发明一种无纺布餐台垫的生产工艺，包括以下步骤：第一步、配料，将以下原料颗粒按各自的重量比配成混合料：PE704240％、PPT30s10％、重质碳酸钙36％、PE蜡9％、硬酯酸锌3％、偶联剂2％；第二步、混料，将第一步获得的混合料在高速搅拌机内运转搅拌均匀；第三步、熔融挤出，将第二步已混合均匀的混合料送进熔融挤出机，并将熔融挤出机渐进控温至处于170-220度摄氏温度下，使所述混合料熔融挤出并且拉成片；第四步、淋复定型，将第三步获得的拉片通过定型冷却辊筒，并且在拉片的前面垫上BOPP印刷花膜，后面垫上无纺布，这样三层经过定型冷却辊筒挤出定型，再收卷成为成品。
优选的，所述偶联剂为固体钛酸酯颗粒。使用本方法的配方生产，增加了材料的厚实手感，但无需增加材料的遮盖性，餐台垫的上面的图案清晰明朗，而下面为无纺布层，不需要遮盖图案，可以省去钛白粉组分。另外，使用本发明的配方生产，材料成本降低了，且可回收利用，更加环保，材料无毒、易分解可再利用，更环保无污染。本发明所述的BOPP印刷花膜是一层透明膜，BOPP是“BiaxiallyOrientedPolypropylene”的简称，即双向拉伸聚丙烯薄膜，BOPP印刷花膜即在BOPP薄膜上印刷有花纹。
此外，本发明并不局限于上述实施方式，只要其以基本相同的手段达到本发明的技术效果，都应属于本发明的保护范围。
