Abstract

本发明公开了一种双面餐台垫的生产工艺，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：PE？7042？38%、PP？T30s？13%、重质碳酸钙32.5%、PE蜡9%、硬酯酸锌2.5%、偶联剂1%、钛白粉4%；第二步混料，将获得的混合料在高速搅拌机内运转搅拌均匀；第三步流延挤出，将已混合均匀的混合料送进流延挤出机，并将流延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、复膜定型，将获得的拉片通过定型冷却辊筒，并且在拉片的前后均垫上BOPP印刷花膜，这样三层经过定型冷却辊筒挤出定型。本发明生产的双面餐台垫上下两面图案更清晰明朗，也不易翻卷扭曲，不易移位。

Description

一种双面餐台垫的生产工艺
技术领域
本发明涉及餐厨用品的生产方法，特别是一种双面餐台垫的生产工艺。
背景技术
现有的双面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，需要对双面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、上下两面的图案清晰互不影响、不易翻卷、扭曲或者移位的双面餐台垫的生产工艺。
本发明解决其技术问题所采用的技术方案是：一种双面餐台垫的生产工艺，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：PE704238％、PPT30s13％、重质碳酸钙32.5％、PE蜡9％、硬酯酸锌2.5％、偶联剂1％、钛白粉4％；
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、流延挤出，将第二步已混合均匀的混合料送进流延挤出机，并将流延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、复膜定型，将第三步获得的拉片通过定型冷却辊筒，并且在拉片的前后均垫上BOPP印刷花膜，这样三层经过定型冷却辊筒挤出定型，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、钛白粉等组成成分，使得本发明方法生产的双面餐台垫的中间层变得厚实且不透明，这样，双面餐台垫的上下两面的图案不再互相影响，而是各自清晰明朗，而且本发明方法生产的双面餐台垫也会不易翻卷、扭曲，不易移位。
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，本发明一种双面餐台垫的生产工艺，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：PE704238％、PPT30s13％、重质碳酸钙32.5％、PE蜡9％、硬酯酸锌2.5％、偶联剂1％、钛白粉4％；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、流延挤出，将第二步已混合均匀的混合料送进流延挤出机，并将流延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、复膜定型，将第三步获得的拉片通过定型冷却辊筒，并且在拉片的前后均垫上BOPP印刷花膜，这样三层经过定型冷却辊筒挤出定型，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，增加了材料的遮盖性，上下两面的图案清晰一致。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。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。
