Description

一种缠绕膜及其制备方法
技术领域
本发明属于包装膜设备领域，具体的说是一种缠绕模及其制备方法。
背景技术
缠绕膜又称“拉伸膜”，具有优越的抗拉性、延伸率大、自粘性好、抗刺穿性和抗撕性，可用于手工缠绕膜，也可用于机用缠绕膜，被广泛用于化工产品、电子产品箱、陶瓷产品、机电设备等集装包装。
近年来，随着缠绕膜生产技术的不断发展，其应用领域越来越广，包括产品的包装、密封、防锈等方面。但是对于质地较脆的产品如玻璃品而言还需要加设体积较大且难以重复利用的泡沫塑料进行包装。一方面泡沫塑料体积较大，所以会占用过多的运输空间；另一方面泡沫塑料强度较低所以需要外套包装箱加以保护，而包装箱又需要进行密封操作，从而提高包装成本。而缠绕膜的成本较低且厚度小，所以理论上恰好能够弥补泡沫塑料的不足之处。
现有技术的缠绕膜仍存在抗拉伸能力不足，使用寿命短的问题，在缠绕包装时，若拉力过稍大，就会出现断裂现象，同时对于一些精密元器件来说不仅需要防止因静电带来的损害，还需要防止因气候、湿润度变化而使产品锈蚀，长时间室外使用，需要产品抗紫外线，因此，我们需要一种抗拉伸性能好，使用寿命长，而且具有防静电、防锈、抗紫外线和耐高温功能的缠绕膜。
发明内容
针对上述背景技术中提到的技术问题，因此，本发明提供了一种缠绕模及其制备方法。
一种缠绕膜，其特征在于，包括缠绕膜本体、第一缠绕层以及第二缠绕层，所述缠绕膜本体设置在所述第一缠绕层和所述第二缠绕层之间，所述第一缠绕层通过喷涂工艺喷涂在所述缠绕膜本体的下端面，所述第二缠绕层通过胶黏层粘合于所述缠绕膜本体的上端面；所述第一缠绕层为抑菌层。
优选的，所述抑菌层为银离子材料制成。
优选的，所述缠绕膜本体由乙烯-乙烯乙酸聚合物、茂金属线性低密度聚乙烯、线性低密度聚乙烯、纳米二氧化硅、全烷基丙烯酸酯共聚乳液、硅烷偶联剂、玻璃纤维、抗氧剂和紫外线吸收剂制备而成。
优选的，所述缠绕膜本体由7至9份乙烯-乙烯乙酸聚合物、9至12份茂金属线性低密度聚乙烯、6至8份线性低密度聚乙烯、4至6份纳米二氧化硅、3至7份全烷基丙烯酸酯共聚乳液、2至4份硅烷偶联剂、3至5份玻璃纤维、1至3份抗氧剂和2至3份紫外线吸收剂制备而成。
优选的，所述第二缠绕层由环氧树脂、乙二醇单乙醚、氯化镁、粉煤灰、增韧剂、增塑剂、稳定剂制备而成。
优选的，所述第二缠绕层由10至15份环氧树脂、15至20份乙二醇单乙醚、6至12份氯化镁、3至5份粉煤灰、1至3份增韧剂、4至6份增塑剂、2至4份稳定剂制备而成。
优选的，所述胶黏层由环氧树脂、丙烯酸、抗氧化剂以及粘合树脂混合制成。
优选的，所述胶黏层由4至6份环氧树脂、5至8份丙烯酸、2至4份抗氧化剂以及3至6份粘合树脂混合制成。
所述缠绕层的制备方法，包括如下步骤：
S1、制备缠绕膜本体：a、将原料混合并进行除尘处理；b、将a步骤中除尘过后的原材料均匀加入挤出机中，挤出机能够将原料充分混合并将其加热熔融形成熔体，原料的熔体温度控制在250℃-280℃；c、将b步骤中的原料熔体由挤出机传送到流延机内，流延机能够将熔体原料加工成薄膜层，薄膜层在流延机上的冷却辊的作用下能够形成缠绕膜本体；
S2、制备第二缠绕层：a、按照重量份数比称取各原料组分；b、将步骤a中的原料投入至均质设备中，均质设备温度控制在90-95℃，均质搅拌转速在2000-3000转/分钟，均质处理2-3h，获得均质混合料；c、将步骤S2中的均质混合料取出并加入至挤压机中，挤压成型，冷却，得到第二缠绕层成品；
S3、制备胶黏层：a、按照重量份数比称取各原料组分；b、将步骤a中的原材料投入到均质设备中搅拌均匀，得到胶黏剂；
S4、通过喷洒的方法将银离子喷涂到步骤S1中缠绕膜本体的下端面，在缠绕膜本体上端面形成第一缠绕层，再将步骤S3中得到的胶黏剂涂抹在缠绕层本体的上端面，再将步骤S2中的第二缠绕层贴合在缠绕层本体的上端面；
S5、分卷加工。
本发明提供了一种缠绕模及其制备方法，有益效果在于:本发明的缠绕膜有经济环保、抗静电、抗拉伸、抗老化、抗雾、用途广泛、安全可靠等优点，同时具有良好的抗菌性、耐候性、稳定性、隔热、抗紫外线、抗自洁净功效；通过添加玻璃纤维使得本发明的缠绕模具有永久抗静电性，在缠绕膜上喷洒银离子溶液，使其具有良好的杀菌性能。
附图说明
附图用来提供对本发明的进一步理解，并且构成说明书的一部分，与本发明的实施例一起用于解释本发明，并不构成对本发明的限制。在附图中：
图1为本发明装置的结构示意图；
图中:1、缠绕膜本体；2、第一缠绕层；3、第二缠绕层；4、胶黏层。
具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者间接在该另一个元件上。当一个元件被称为是“连接于”另一个元件，它可以是直接连接到另一个元件或间接连接至该另一个元件上。
下面结合附图详细说明本发明的最优实施方式。
如图1所示，一种缠绕膜，包括缠绕膜本体1、第一缠绕层2以及第二缠绕层3，所述缠绕膜本体1设置在所述第一缠绕层2和所述第二缠绕层3之间，所述第一缠绕层2通过喷涂工艺喷涂在所述缠绕膜本体1的下端面，所述第二缠绕层3通过胶黏层4粘合于所述缠绕膜本体1的上端面；所述第一缠绕层2为抑菌层。缠绕膜本体1上的第一缠绕层2具有杀菌的作用，通过缠绕膜本体1和第二缠绕层3的结合，可以提高整个缠绕膜的抗拉伸作用。
抑菌层为银离子材料制成，当银离子与细菌接触时，即与细菌体内带负电的活性酶产生库仑力而强烈吸附，并与酶蛋白中的活性基团发生作用，使蛋白质凝固，从而可破坏细胞合成酶的活性，使细胞丧失分裂增殖的能力而死亡，细菌死亡后，银离子又会从细菌尸体中游离出来，再和其他细菌结合，因此，可使抗菌材料具有抗菌性能的长效性。
其中，所述缠绕膜本体1由乙烯-乙烯乙酸聚合物、茂金属线性低密度聚乙烯、线性低密度聚乙烯、纳米二氧化硅、全烷基丙烯酸酯共聚乳液、硅烷偶联剂、玻璃纤维、抗氧剂和紫外线吸收剂制备而成。
所述缠绕膜本体1由8份乙烯-乙烯乙酸聚合物、12份茂金属线性低密度聚乙烯、6份线性低密度聚乙烯、5份纳米二氧化硅、3份全烷基丙烯酸酯共聚乳液、4份硅烷偶联剂、3份玻璃纤维、3份抗氧剂和2份紫外线吸收剂制备而成。使之具有防静电、防锈、抗紫外线和耐高温功能。
所述第二缠绕层3由环氧树脂、乙二醇单乙醚、氯化镁、粉煤灰、增韧剂、增塑剂、稳定剂制备而成。所述第二缠绕层由15份环氧树脂、18份乙二醇单乙醚、7份氯化镁、4份粉煤灰、3份增韧剂、4份增塑剂、4份稳定剂制备而成。环氧树脂的交联聚合使第二缠绕层具有抗拉性能，进一步的提高缠绕模本体的抗拉性能。
另外，所述胶黏层4由环氧树脂、丙烯酸、抗氧化剂以及粘合树脂混合制成。所述胶黏层由4份环氧树脂、7份丙烯酸、3份抗氧化剂以及6份粘合树脂混合制成。
所述缠绕层的制备方法，包括如下步骤：
S1、制备缠绕膜本体：a、将原料混合并进行除尘处理；b、将a步骤中除尘过后的原材料均匀加入挤出机中，挤出机能够将原料充分混合并将其加热熔融形成熔体，原料的熔体温度控制在250℃-280℃；c、将b步骤中的原料熔体由挤出机传送到流延机内，流延机能够将熔体原料加工成薄膜层，薄膜层在流延机上的冷却辊的作用下能够形成缠绕膜本体；
S2、制备第二缠绕层：a、按照重量份数比称取各原料组分；b、将步骤a中的原料投入至均质设备中，均质设备温度控制在90-95℃，均质搅拌转速在2000-3000转/分钟，均质处理2-3h，获得均质混合料；c、将步骤S2中的均质混合料取出并加入至挤压机中，挤压成型，冷却，得到第二缠绕层成品；
S3、制备胶黏层：a、按照重量份数比称取各原料组分；b、将步骤a中的原材料投入到均质设备中搅拌均匀，得到胶黏剂；
S4、通过喷洒的方法将银离子溶液喷涂到步骤S1中缠绕膜本体的下端面，在缠绕膜本体上端面形成第一缠绕层，再将步骤S3中得到的胶黏剂涂抹在缠绕层本体的上端面，再将步骤S2中的第二缠绕层贴合在缠绕层本体的上端面；
S5、分卷加工。
