Description

一种灭虫塑料地膜及其制作工艺
技术领域
本发明涉及农用膜领域，具体涉及一种灭虫塑料地膜及其制作工艺。
背景技术
地膜即地面覆盖薄膜，通常是透明或黑色PE薄膜，也有绿、银色薄膜，用于地面覆盖，以提高土壤温度，保持土壤水分，维持土壤结构，防止害虫侵袭作物和某些微生物引起的病害等，促进植物生长的功能。地膜看上去薄薄一层，但作用相当大。不仅能够提高地温、保水、保土、保肥提高肥效，而且还有灭草、防病虫、防旱抗涝、抑盐保苗、改进近地面光热条件，使产品卫生清洁等多项功能。对于那些刚出土的幼苗来说，具有护根促长等作用。对于我国三北地区，低温、少雨、干旱贫脊、无霜期短等限制农业发展的因素，具有很强的针对性和适用性，对于种植二季水稻育秧及多种作物栽培上也起了作用。在全国31个省市自治区普及和应用，用于粮、聚乙烯树脂、油、菜、瓜果、烟、糖、药、麻、茶、林等40多种农作物上，使作物普遍增产30%－50%，增值40%－60%，深受广大农民的欢迎。
发明内容
针对现有技术的不足，本发明的目的在于提供一种灭虫塑料地膜及其制作工艺。
本发明解决的技术问题可以采用以下技术方案来实现：一种灭虫塑料地膜，包括地膜本体，其中所述地膜本体包括第一膜体与第二膜体，第一膜体两面分别设有竹纤维涂层与棉纤维，第二膜体包括两层覆膜以及位于两层覆膜之间的驱虫颗粒。
优选的，所述第一膜体包括以下成分，聚乙烯30--60份、含氟共聚物10--30份、聚乳酸10--30份、增塑剂5--10份、甲草嗪0--2份、降解母粒40--46份。
优选的，所述覆膜包括以下成分，聚乙烯树脂50--70份、聚乙烯8--10份、含氟共聚物1.5--2.2份、尿素0.8--1.2份、粘合剂3--5份、润滑剂0--1.5份、降解母粒3--5份、辅料30--50份。
优选的，所述驱虫颗粒包括以下成分，天然树脂50--80份、植物提取液10--15份以及辣椒素3--5份。
优选的，所述植物提取液是香樟、洋葱、松节油、桉树、艾草、金莲花、玻璃苣、艾叶、菖蒲、薄荷油、松节油的提取液的一种或几种的混合液。
一种灭虫塑料地膜的制作工艺，其中包括以下步骤：（1）将聚乙烯、含氟共聚物、聚乳酸、增塑剂、甲草嗪、降解母粒按所述配方的比例混合搅匀，之后在150--200°下加热、塑化，并在双螺杆挤出机对塑化后的混合体进行挤压，得到所述第一膜体；
（2）将聚乙烯树脂、聚乙烯、含氟共聚物、尿素、粘合剂、润滑剂、降解母粒、辅料按所述配方的比例均匀混合，之后在120--180°下加热、塑化，并在双螺杆挤出机对塑化后的混合体进行挤压；得到所述覆膜；
（3）将香樟、洋葱、松节油、桉树、艾草、金莲花、玻璃苣、艾叶、菖蒲、薄荷油、松节油进行提取得到提取液，将提取液中的一种或几种混合，得到植物提取液；
（4）将天然树脂、植物提取液以及辣椒素按所述配方的比例均匀混合加热到50--80°，置入模具中冷却成型，得到所述驱虫颗粒；
（5）将第一膜体的两面分别涂上黑色的涂层与白色的涂层；
（6）将两层覆膜对齐，中间置入驱虫颗粒，并置于加压机上加压成型，得到第二膜体；
（7）将第一膜体与第二膜体置入加压机内加压，得到所述地膜本体。
有益效果是：本地膜通过两层膜体组成，第一膜体有黑色的涂层与白色的涂层，使得第一膜体的外表面可以向四周反射阳光中的紫外线，而抑制可见光的反射。害虫因忌怕紫外光而不敢靠近薄膜，故能起到防虫效果。第二膜体通过覆膜与棉纤维可以进行驱虫的作用。同时覆膜与棉纤维都是采用可降解的成分，更加安全环保。
本发明添加了特殊的粘合剂，使制得的地膜具有很好的生物降解性能，添加的紫外线 吸收剂能对紫外线进行遮蔽，甲草胺乳油和甲草嗪的加入使得地膜具有良好的驱虫性能， 能防止害虫侵袭作物和某些微生物引起的病害等，促进植物生长的功能。用于地面覆盖提 高土壤温度，保持土壤水分，使作物普遍增产。
本发明工艺流程简洁，原料配比合理，采用的均为无毒无害 的化学物质与草药制作，制备的塑料地膜，使用效果好，同时具有灭杀虫害的功用，不仅保 证了地膜原有的功用，还有灭虫的功效，一举两得，使用效果明显，市场价值高，便于推广及 使用。

一种灭虫塑料地膜的制作工艺，其中包括以下步骤：（1）将聚乙烯、含氟共聚物、聚乳酸、增塑剂、甲草嗪、降解母粒按所述配方的比例混合搅匀，之后在150°下加热、塑化，并在双螺杆挤出机对塑化后的混合体进行挤压，得到所述第一膜体1；（2）将聚乙烯树脂、聚乙烯、含氟共聚物、尿素、粘合剂、润滑剂、降解母粒、辅料按所述配方的比例均匀混合，之后在180°下加热、塑化，并在双螺杆挤出机对塑化后的混合体进行挤压；得到所述覆膜3；（3）将香樟、洋葱、松节油、桉树、艾草、金莲花、玻璃苣、艾叶、菖蒲、薄荷油、松节油进行提取得到提取液，将提取液中的一种或几种混合，得到植物提取液；（4）将天然树脂、植物提取液以及辣椒素按所述配方的比例均匀混合加热到80°，置入模具中冷却成型，得到所述驱虫颗粒4；（5）将第一膜体1的两面分别涂上黑色的涂层与白色的涂层；（6）将两层覆膜3对齐，中间置入驱虫颗粒4，并置于加压机上加压成型，得到第二膜体2；（7）将第一膜体1与第二膜体2置入加压机内加压，得到所述地膜本体。
基于上述，本地膜通过两层膜体组成，第一膜体1有黑色的涂层与白色的涂层，使得第一膜体1的外表面可以向四周反射阳光中的紫外线，而抑制可见光的反射。害虫因忌怕紫外光而不敢靠近薄膜，故能起到防虫效果。第二膜体2通过覆膜3与棉纤维4可以进行驱虫的作用。同时覆膜3与棉纤维4都是采用可降解的成分，更加安全环保。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
