Description

一种废旧地膜回收再利用方法
技术领域
本发明属于农业废弃物再利用技术领域，具体是一种废旧地膜回收再利用方法。
背景技术
地膜覆盖技术自90年代开始大面积推广使用，由于其技术具有蓄水保墒、提高地温、延长作物生长期、促进作物生长、增加产量，同时可降低冰雹、干旱、风沙及温差等自然灾害给作物生长带来的不利影响等显著特点，给农业生产带来巨大经济效益，为推动农村经济的持续发展起到了积极的作用。但据调查，使用地膜的耕地中，每年有30％左右不可降解地膜残留在30厘米深的耕作层中，连续18年使用地膜的地块中，每亩地膜残留量在2公斤以上。这些地膜残留，在自然条件下极难降解，在土壤内可存在200-400年，存留的农用膜破坏土壤的物理和化学结构，可抑制土壤微生物的生长，降低土壤的透气性、透水性，影响耕地质量；最终导致作物难以发芽出苗，阻碍作物根系生长，减少作物对土壤水分养分的吸收，导致作物减产，影响农产品的产量和质量，使农民的收入受到极大的影响。目前，地膜覆盖栽培技术已从棉花发展到蔬菜、瓜类和特色作物。现在地膜已经与种子、化肥、农药一起成为不可缺少的农资，地膜使用面积逐年增加。由于过量使用地膜，致使大量废旧地膜不能及时收回，大量残留农田的塑料薄膜在土壤中日积月累会形成阻隔层，影响作物根系对水肥的吸收，造成减产和土壤环境污染。即使是对使用后的农膜进行了捡拾清理，但是因为没有较好地处理方法，或是在田间地头及河道两岸堆放，无人管理，造成随风飞扬的景观污染；或是随雨水冲刷进入河道和水体，污染环境；或是就地焚烧，均会给环境造成严重的二次污染。而且，混有塑料的生活垃圾不适用堆肥。所有这些曾经给中国农业生产带来福音的“白色革命”如果不找到一个行之有效地处置手段，就转变成了“白色污染”，废旧地膜回收清理已到了刻不容缓的地步。
发明内容
本发明的目的是提供一种废旧地膜回收再利用方法，将废旧地膜回收再加工制成穿线管，在降低塑料废弃物污染的同时，实现了资源的循环利用和可持续发展，有力改善农业生态环境，保护耕地及实现农业清洁生产，制成的穿线管界面相容性、光稳定性及耐候性好。
为了达到上述目的，本发明采用以下技术方案。
一种废旧地膜回收再利用方法，包括以下步骤：
⑴清洗分拣：将废旧地膜投入清洗池清洗，捞出后摊开、晾晒，将废旧地膜分拣出无色地膜和黑色地膜，将无色地膜破碎后摩擦清洗15-35min，捞出后45-55℃烘干，熔融造粒，得到无色地膜粒子；将黑色地膜破碎后摩擦清洗15-35min，捞出后45-55℃烘干，熔融造粒，得到黑色地膜粒子；
⑵改性处理：按重量份数计，将黑色地膜粒子50-100份、碳纤维3-5份、硅烷偶联剂0.5-1.5份、纳米硅藻土0.1-1份、聚丙烯酰胺0.3-0.7份混匀后，熔融造粒，得到改性黑色地膜粒子；将无色地膜粒子85-100份、钛酸酯偶联剂1-3份、硬脂酸锌0.1-0.5份、钛酸钾晶须0.5-1.5份混匀后，熔融造粒，得到改性无色地膜粒子；
⑶挤出成型：按重量份计，将改性黑色地膜粒子5-10份、改性无色地膜粒子25-45份、PVC90-100份、环氧树脂5-10份、不饱和聚酯树脂5-15份、2,6-二叔丁基-4-甲基苯酚0.3-0.5份、双十二碳醇酯0.1-0.3份、甲基硅油0.2-0.4份、失水山梨醇月桂酸酯0.1-0.3份、硬脂酸锌0.2-0.5份、羧甲基纤维素0.1-0.5份混匀，经双螺杆挤出机挤出，制得穿线管。
