Description
技术领域
本发明涉及一种高强度的大棚用薄膜及制备方法。
背景技术
随着农业科技日益发展，大棚薄膜的要求越来越高，各种功能薄膜不断出现。市场上大棚的覆盖材料多为玻璃、聚氯乙烯薄膜（PVC）、低密度聚乙烯（LDPE）薄膜和乙烯-醋酸乙烯共聚物（EVA）薄膜等。这些大棚薄膜在受到强风或者暴雨的侵袭时容易破损，从而使得农作物出现病果、裂果、减少作物的收获量。因此需要研究一种高强度的大棚用薄膜及制备方法。
发明内容
本发明的目的是为了解决上述现有技术的不足而提供一种高强度的大棚用薄膜及制备方法。
为了实现上述目的，本发明所设计的一种高强度的大棚用薄膜，各组分的重量配比为聚甲基戊烯70~90份、高强度纳米填料2~5份、增塑剂5~10份、增粘剂2~5份、抗氧剂2~3份、稀土1~2份和金属锆2~4份，其中稀土与金属锆的重量比为1:2，所述高强度纳米填料中各组分的重量配比为氧化硅10~40份、氧化铝20~30份、氧化钙20~30份、氧化钛20~30份、氧化锑5~10份和氮化硼5~15份。
所述稀土为钕、钷、钐和铕中的一种。所述增塑剂为柠檬酸三丁酯。所述增粘剂为聚甲基丙烯酸酯。
上述高强度纳米填料由氧化硅、氧化铝、氧化钙、氧化钛、氧化锑和氮化硼这6种无机物组成，可以促进薄膜的成膜性，并提高薄膜的强度；同时通过加入稀土与金属锆，则能有效地促进高强度纳米填料发挥其特性，使得薄膜的强度提高。
柠檬酸三丁酯作为增塑剂，聚甲基丙烯酸酯作为增粘剂，则提高了薄膜的可拉伸性，延长使用寿命。
一种高强度的大棚用薄膜的制备方法，首先按上述的原材料进行按重量份配方，然后将配好量的氧化硅、氧化铝、氧化钙、氧化钛、氧化锑和氮化硼放入高温炉中进行熔融加热，加热温度为500~600℃，冷却后得到高强度纳米填料，接着将配好量的聚甲基戊烯、高强度纳米填料、增塑剂、增粘剂、抗氧剂放入挤出机中进行熔融、塑化，温度为250~300℃，保温60min，接着加入配方量的稀土和金属锆继续熔融，温度180~220℃，保温30min，最后挤出吹膜，收卷即得所述的高强度的大棚用薄膜。
本发明得到的一种高强度的大棚用薄膜，其强度优于普通塑料薄膜的强度，经测试，该大棚用薄膜的拉伸强度为130~155MPa，断裂伸长率为40~50%。
