Description

薄膜连接方法、其制得的宽幅薄膜和 用该膜的农用覆盖材料
技术领域
本发明涉及薄膜的连接方法、由此连接方法制得的宽幅薄膜、以及使用该宽幅薄膜的农用覆盖材料。
背景技术
通常，使用宽幅薄膜作为农用覆盖材料。工业上制造的薄膜，例如农用聚氯乙烯薄膜(以下称农用薄膜)的幅宽为1～4米。用作农用覆盖材料的宽度不够。为此，将该薄膜连接后得到更加宽幅的薄膜作为农用覆盖材料。作为薄膜的连接方法，通常采用使二张薄膜的端部重合，再热压重合部分的连接方法。
即使在使用由氟树脂(例如乙烯/四氟乙烯共聚物(以下称ETFE))形成的氟树脂薄膜或者由聚烯烃(例如聚乙烯、乙烯/乙酸乙烯酯共聚物)形成的聚烯烃薄膜并且这些薄膜不含亲水化处理表面的情况下，也可采用和农用薄膜相同的使两张薄膜的端部重合再热压重合部分的连接方法。
但是，在用不含亲水化处理表面的薄膜建造农用暖房时，由于薄膜内侧的水分结露后形成的水滴，使薄膜的光透射率降低，或者薄膜上的水滴滴落在农作物上，妨碍农作物的生长。上述问题通常通过对作为农用覆盖材料的薄膜实施亲水化处理，赋予其防水滴性得到解决。
作为农用薄膜，通常采用由掺有亲水剂的聚氯乙烯所形成的薄膜，使其产生亲水效果。对于含亲水剂的薄膜，可将两张薄膜的端部相互重合后热压重合部分，使重合部分熔融粘合，容易地制得宽幅薄膜。
在使用氟树脂时，由于氟树脂具有高的模塑温度，使工业上使用的亲水剂分解，因此不能采用掺亲水剂的方法。为此，采用在氟树脂薄膜表面涂布亲水性物质的亲水化处理方法。但是，在具有这种亲水化处理表面的氟树脂薄膜中，在将两张薄膜相互重合后热压重合部分以连接薄膜时，由于存在亲水化处理表面，使重合部分不能充分熔融粘合。
而用聚烯烃时，可采用和聚氯乙烯相同的掺入亲水剂的方法。但是，为提高亲水化处理效果的持久性，也有采用表面涂布亲水性物质的亲水化处理方法。但在后者的情况下，和氟树脂相同其亲水化处理表面成为障碍，使重合部分不能充分熔融粘合。
作为解决上述问题的方法，可采用在对薄膜的一面进行亲水化处理时，掩蔽薄膜的端部，形成没有涂布亲水性物质的部分。将该部分与未经亲水化处理表面重合后热压该重合的部分进行熔融粘合的方法。但是，用上述方法时由于增加了掩蔽步骤，使薄膜的制造工程复杂，提高了宽幅薄膜的成本。
本发明的目的是提供在一个面上有亲水化处理表面的薄膜(A)的连接方法。
本发明的另一个目的是提供用上述连接方法反复操作一次以上制得的宽幅薄膜，以及用该宽幅薄膜形成的农用覆盖材料。

实施本发明的最佳方式
下面参照附图描述本发明薄膜连接方法的较好实例。
图1所示是在一个表面上有亲水化处理表面的薄膜(A)的截面示意图。薄膜(A)1和薄膜(B)4在薄膜(A)的非亲水化处理表面一侧的熔融粘合部6熔融粘合，从而使两张薄膜(A)经由薄膜(B)连接起来。本发明书中所谓连接，其含义是经熔融粘合后结合在一起。
图2所示是薄膜(A)连接步骤的一个例子，在步骤(I)中，将两张在一面上有亲水化处理表面的薄膜(A)1放置成其端部对置紧靠并且亲水化处理表面朝向一致。在步骤(II)中，在薄膜(A)的非亲水化处理表面3一侧使薄膜(B)4横跨两张薄膜(A)1的对置处并重合其上，形成重合部(C1)5。接着，在步骤(III)中，用热压机的上部加热器和下部加热器7热压重合部(C1)5，形成熔融粘合部6，从而使两张薄膜(A)经由薄膜(B)连接起来。
在步骤(III)中，为防止薄膜(A)和薄膜(B)粘附在热压机的上部和下部的加热器7上，较好使用脱模板8。另外，两张薄膜(A)对置的端部可面对面紧贴或者不紧贴，留有间隙。在留有间隙时，该间隙宜为0.01-88毫米，较好为0.05-50毫米，最好为0.1-30毫米。
在本发明的连接方法中，将两张在一面上有亲水化处理表面的薄膜(A)放置成其端部对置紧靠并且其亲水化处理表面朝向一致，然后，在薄膜(A)的非亲水化处理表面一侧，使一张薄膜(B)横跨两张薄膜(A)的对置处并重合其上，对该重合部(C1)进行热压，从而使二张薄膜(A)连接起来。
对所述重合部(C1)进行热压粘合时，适宜的温度范围是比构成薄膜(A)及薄膜(B)的树脂的熔点低30℃至高20℃的温度。热压粘合时的加热温度较好是比构成薄膜的树脂的熔点低15℃至高20℃，更好是低20℃至高10℃，最好是低15℃至高5℃，优选是树脂的熔点至比树脂熔点高5℃的温度。
较好在比构成薄膜(A)和薄膜(B)的树脂的熔点低5℃至高20℃的温度范围内对所述重合部(C1)中，薄膜(B)和各张薄膜(A)的重合部(C2)的中央部(C3)进行热压粘合，然后，在比所述熔点低30℃至低5℃的温度范围内对所述重合部(C1)热压粘合。
图3所示是本发明薄膜(A)连接方法的又一例子，和图2相同在步骤(I)和步骤(II)形成重合部(C1)5。然后，在步骤(III)中，用梳型上部加热器和下部加热器，在比构成薄膜(A)和薄膜(B)的树脂熔点低5℃至高20℃的温度范围，对所述重合部(C1)5中薄膜(B)和各张薄膜(A)的重合部(C2)10的中央部(C3)11进行热压粘合，使之熔融粘合。
接着，在步骤(IV)中，用上部和下部加热器7，在比所述树脂熔点低30℃至低5℃的温度范围，对薄膜(A)和(B)的所述重合部(C1)5进行热压粘合，使得除中央部(C3)11以外的部分熔融粘合。以下，把在比所述熔点低5℃至高20℃的温度范围内进行熔融粘合的中央部(C3)称为高温熔融粘合部12，把在比所述熔点低30℃至低5℃的温度范围内进行熔融粘合的部分称为低温熔融粘合部13。
中央部(C3)的加热温度较好为所述树脂的熔点至比所述熔点高10℃的温度，较好使用梳型上部加热器9热压中央部(C3)。步骤(III)和步骤(IV)的操作顺序也可互换。在这种情况下，首先使所述重合部(C1)5全部成为低温熔融粘合部，然后再使中央部(C3)成为高温熔融粘合部。
在对薄膜进行热压使之熔融粘合后，宜于插入使熔融粘合后的薄膜(A)和薄膜(B)冷却的冷却步骤，例如可使用空气冷却和冷却板。使用冷却步骤进一步提高了薄膜(A)和脱膜板(输送皮带)间的剥离性。
图4所示是在图3的方法中所用的热压机的热压粘合部的截面图。所述热压粘合部顺着薄膜输送方向包括：一对梳型上部加热器9和加热器7，用于在比所述树脂的熔点低5℃至高20℃的温度范围内对中央部(C3)进行热压粘合；一对加热器7，用于在比氟树脂的熔点低30℃至低5℃的温度范围内对全部重合部进行热合粘合；以及冷却板14。在热压粘合步骤中用脱模板8输送薄膜。尽管在热压时的压力是由加热器自重形成的压力，但也可增加负荷使压力升高。压力宜为0.01～10MPa，更好为0.1～1MPa。
薄膜(B)可以是两面都是未经亲水化处理表面的薄膜，也可以是一面有亲水化处理表面的薄膜。在使用一面有非亲水化处理表面的薄膜时，薄膜(A)和薄膜(B)的热压粘合是在非亲水化处理表面上实施的。作为薄膜(B)，最好在两面都有非亲水化处理表面的薄膜。
薄膜(A)的幅宽宜为50～250厘米，更好为110～160厘米，因为上述幅宽范围是农用覆盖材料的标准幅宽。薄膜(A)的厚度宜为10～300微米，更好为50～100微米，因为在上述范围的薄膜具有优良的强度，加热时的导热性也好。
薄膜(B)的幅宽宜为2～10厘米，较好为2.5～6厘米，更好为3～5厘米，因为在上述范围的薄膜可使用小型热压粘合装置。薄膜(B)的厚度宜为30～300微米，更好为100～150微米，因为在上述范围的薄膜具有足够的强度，加热时的导热性也好。
薄膜(A)和薄膜(B)的重合部的幅宽总计为1～8厘米，更好为1.5～6厘米，最好为2～4厘米。而薄膜(B)和一张薄膜(A)的重合部的幅宽宜为0.5～4厘米，更好为0.75～3厘米，最好为1～2厘米。
薄膜(B)与两张薄膜(A)的熔融粘合部的宽度总计宜为1-8厘米，更好为1.5-6厘米，最好为2-4厘米。另外，薄膜(B)与任何一张薄膜(A)的熔融粘合部的宽度宜为0.5-4厘米，更好为0.75-3厘米，最好为1-2厘米。这种宽度范围可得到足够的熔融粘合力，而且可使用更小型的热压粘合装置。
较好热压薄膜(B)和薄膜(A)，使之在整个重合部(C1)区域熔融粘合。更好的热压粘合是在薄膜(B)的二端有一定幅宽未熔融粘合。另外，较好进行热压，从而如图1所示在各张膜(A)的对接部分存在一个具有预定宽度的非熔融粘合部分。并且在薄膜(B)的两端存在具有预定宽度的非熔融粘合部分。薄膜(B)两端和薄膜(A)对接部分的非熔融粘合部分的宽度宜为0.1～10毫米，更好为0.3～5毫米，最好为0.5～3毫米。
在本发明中，将上述薄膜的连接方法反复操作一次以上，使两张或多张薄膜(A)连接，得到幅宽1～150米的宽幅薄膜，较好幅宽8～60米的宽幅薄膜，因为其操作性等优异。
在本发明中，使用幅宽1～150米的宽幅薄膜，优选使用幅宽8～60米的宽幅薄膜形成农用覆盖材料。
本发明的薄膜(A)和薄膜(B)较好为氟树脂薄膜或聚烯烃薄膜。
氟树脂薄膜可以是例如：由PTFE、四氟乙烯/全氟(烷基乙烯基醚)共聚物(以下称PFA)、四氟乙烯/六氟丙烯共聚物(以下称FEP)、聚三氟氯乙烯(CTFE)、聚偏二氟乙烯(PVDF)、聚氟乙烯等形成的薄膜。较好由PTFE、PFA或FEP形成的薄膜，更好由ETFE形成的薄膜。
ETFE较好包括四氟乙烯(以下称TFE)和乙烯(以下称E)的共聚物，以及TFE、E和其它单体的共聚物。
所述其它单体可以是例如氟代烯烃(如三氟氯乙烯、六氟丙烯、全氟(烷基乙烯基醚)、偏二氟乙烯等)；多氟烷基乙烯(如CH2＝CHRf(Rf表示碳原子数1～8的多氟烷基，以下同)或CH2＝CFRf)；多氟烷基三氟乙烯基醚(如CF2＝CFOCH2Rf等)。这些单体可单独使用或两种以上组合使用。
具体地说，CH2＝CHRf是较好的，其中Rf较好是碳原子数3～6的全氟烷基，优选C4F9。
在ETFE的组成中，基于TFE的聚合单元/基于E的聚合单元的摩尔比较好为70/30～30/70，更好为65/35～40/60，最好为60/40～45/55。
在含有基于其它共聚单体的聚合单元时，所述基于其它共聚单体的聚合单元的含量，按基于TFE和乙烯的聚合单元的总摩尔数计，较好为0.01～30摩尔％，更好为0.05～15摩尔％，最好为0.1～10摩尔％。
本发明聚烯烃薄膜可以是例如：由聚乙烯、乙烯/乙酸乙烯酯共聚物、聚丙烯、乙烯/丙烯共聚物等形成的薄膜；由聚乙烯和乙烯/乙酸乙烯酯共聚物的层合物形成的薄膜等。较好由聚乙烯或乙烯/乙酸乙烯酯共聚物形成的薄膜，或由聚乙烯和乙烯/乙酸乙烯酯共聚物的层合物形成的薄膜；更好由聚乙烯或乙烯/乙酸乙烯酯共聚物形成的薄膜。
在制造用于本发明的一面有亲水化处理表面的薄膜(A)时，作为形成亲水化处理表面的方法可采用湿法和干法。所述湿法可以是：用辊涂布亲水性物质溶液的方法、喷涂该溶液的方法、用刷子刷涂该溶液的方法、用涂布机涂布该溶液的方法等。较好是用涂布机涂布亲水性物质溶液的方法、或喷涂该溶液的方法。
所述干法可以是：亲水性物质的溅涂法、真空蒸涂法、CVD法、离子涂布法等。较好是亲水性物质的溅涂法，因其产率高、亲水性的持续性好。
所述亲水性物质可以是例如：无机(例如SiO2、Al2O3等)的胶体溶胶、聚乙烯醇、亲水性树脂(如丙烯酸等)、金属(如Si、Sn、Ti、Nb、Al、Zn等)的氧化物等。
具体地说，较好使用金属(如Si、Sn、Ti等)的氧化物的溅涂法，此时，最好使用金属(如Si和/或Sn)的氧化物。
由于实施了前述亲水化处理，因此本发明农用覆盖材料具有优良的抗液滴性。在使用本发明农用覆盖材料的农用暖房中，即使出现暖房设施内的水分结露在薄膜制成的暖房设施内表面的情况，水滴也容易流动，很少产生水滴落在作物上阻碍作物生长的情况。
在本发明粘合方法中，由于重合部能充分熔融粘合，因此熔融粘合部可长期不剥离，防止水和污染物侵入暖房等设施内。
使用本发明连接方法形成的幅宽1～150米的宽幅薄膜可适用于农用覆盖材料，而且也适合作为例如帐篷材料、袋材、防水板材、止水板材等用途。
以下通过实施例具体说明本发明，但本发明不受这些实施例限制。
