Description

一种生物炭基塑料膜材料及其制备方法
技术领域
本发明涉及一种塑料膜材料，特别涉及一种可降解的生物炭基塑料膜材料及其制备方法。
背景技术
塑料薄膜是一种用聚氯乙烯、聚乙烯、聚丙烯、聚苯乙烯及其他树脂制成的薄膜，塑料薄膜用量大、品种多、应用范围广，市场前景广阔，需求量在不断增长。近年来，为了实现农作物的短期的种植或季节外种植，人们在塑料薄膜的覆盖下进行有用作物的载培，即广泛地进行所谓的遮盖载培或隧道栽培。
农业用地膜的主要成分为聚乙烯或聚丙烯，是目前世界上生产量最大的塑料制品。地膜的使用有利于作物的生长发育，提高作物产量。然而，地膜使用量的增加及其难降解性使土壤中残膜及其碎片增多，引起土壤板结、通透性变差，造成农作物减产，其难回收性导致其废弃在自然界中，对生态环境危害很大。
发明内容
本发明的目的在于提供一种生物炭基塑料膜材料，通过改性技术，把生物炭同塑料结合在一起，既可减少在农业中塑料的用量，又可加速塑料制品的分解过程，达到环境保护的目的。
本发明还提供了上述生物炭基塑料膜材料的制备方法。
本发明解决其技术问题所采用的技术方案是：
一种生物炭基塑料膜材料，由以下重量份计的原料混合制成：改性生物炭20-40份，聚乙烯40-60份，分散剂1.5-2份，偶联剂1-2.5份。
作为优选，所述改性生物炭的制备方法为：向生物炭中加入稀酸溶液，稀酸溶液用量为生物炭重量的3-7％，搅拌混合均匀后，在150-220℃下干燥至含水量小于0.2％。采用本发明的改性方法，使生物炭表面的亲水基团减少，而亲油基团增加，使它能更好地同塑料结合，减少塑料的用量。
作为优选，所述生物炭的制备方法为：将木质或竹质材料在无氧或含氧量低于3％低氧的条件下，700-1000℃高温裂解2-5小时，冷却，粉碎，过筛。采用本发明的方法制备的生物炭，生物炭的固定C含量大于75％，比表面积大于250m2/g，改性后与聚乙烯的结合效果好。
作为优选，所述稀酸溶液选自质量浓度为0.5-1.5％的硝酸溶液、质量浓度为1-3％的磷酸溶液中的一种或两种的混合物。
作为优选，所述聚乙烯为低密度聚乙烯、线性低密度聚乙烯或两者的混合物。
作为优选，所述分散剂选自聚乙烯蜡、氧化聚乙烯蜡中的一种或两种的混合物。
作为优选，所述偶联剂选自硅烷偶联剂KH550、KH560、KH570、KH792、DL602中的一种或几种。
一种生物炭基塑料膜材料的制备方法，将改性生物炭、聚乙烯、分散剂及偶联剂投入密炼机中，升温至120-150℃，密炼15-20min，然后将密炼好的物料转入破碎机中，边破碎边冷却，待破碎到3厘米大小以下碎片，温度在40℃以下时，再将破碎机加工完的物料转入双螺杆挤出机中，加热在温度180-200℃的范围内熔融塑化，挤出造粒。
本发明的有益效果是：
(1)采用改性技术，使生物炭表面的亲水基团减少，而亲油基团增加，使它能更好地同塑料结合，减少了塑料的用量。
(2)在传统的薄膜原料中加入生物炭，降低了环境风险，由于生物炭的存在，能为微生物提供繁殖场所，增加微生物的活性，从而增加土壤环境中塑料的可降解性能，同时，有能增加土壤中的固碳能力。
(3)减少了生产成本。
具体实施方式
下面通过具体实施例，对本发明的技术方案作进一步的具体说明。
本发明中，若非特指，所采用的原料和设备等均可从市场购得或是本领域常用的。下述实施例中的方法，如无特别说明，均为本领域的常规方法。
实施例1：
将改性生物炭20kg、聚乙烯(低密度聚乙烯，市售)40kg、分散剂(聚乙烯蜡)1.5kg及硅烷偶联剂(KH550)1kg投入密炼机中，升温至120℃，密炼20min，然后将密炼好的物料转入破碎机中，待破碎成大小3cm以下的小片，温度小于40℃时，再将破碎机加工完的物料转入双螺杆挤出机中，加热到180℃，熔融塑化，挤出造粒。
改性生物炭的制备方法为：向生物炭中加入质量浓度为0.5％的硝酸溶液，硝酸溶液用量为生物炭重量的7％，搅拌混合均匀后，在150℃下干燥至含水量小于0.2％。
生物炭的制备方法为：将木质材料在无氧条件下，700℃高温裂解5小时，冷却，粉碎，过1000目筛。
实施例2：
将改性生物炭40kg、聚乙烯(低密度聚乙烯与线性低密度聚乙烯按1:1的质量比的混合物)60kg、分散剂(聚乙烯蜡与氧化聚乙烯蜡按1:1的质量比的混合物)2kg及硅烷偶联剂(KH560)2.5kg投入密炼机中，升温至150℃，密炼15min，然后将密炼好的物料转入破碎机中，待破碎成大小3cm以下的小片，温度小于40℃时，再将破碎机加工完的物料转入双螺杆挤出机中，加热到200℃，熔融塑化，挤出造粒。
改性生物炭的制备方法为：向生物炭中加入质量浓度为3％的磷酸溶液，磷酸溶液用量为生物炭重量的3％，搅拌混合均匀后，在220℃下干燥至含水量小于0.2％。
生物炭的制备方法为：将竹质材料在含氧量低于3％的低氧条件下，1000℃高温裂解2小时，冷却，粉碎，过1200目筛。
实施例3：
将改性生物炭30kg、聚乙烯(线性低密度聚乙烯，市售)50kg、分散剂(氧化聚乙烯蜡，市售)1.8kg及硅烷偶联剂(KH550与KH570按1:1的质量比的混合物)2kg投入密炼机中，升温至130℃，密炼18min，然后将密炼好的物料转入破碎机中，待破碎成大小3cm以下的小片，温度小于40℃时，再将破碎机加工完的物料转入双螺杆挤出机中，加热到190℃，熔融塑化，挤出造粒。
改性生物炭的制备方法为：向生物炭中加入稀酸溶液(质量浓度为1.5％的硝酸溶液与质量浓度为1％的磷酸溶液按照1:1的体积比的混合物)，稀酸溶液用量为生物炭重量的5％，搅拌混合均匀后，在200℃下干燥至含水量小于0.2％。
生物炭的制备方法为：将竹质材料在无氧条件下，800℃高温裂解3.5小时，冷却，粉碎，过1000目筛。
把本发明制得的母粒加入吹塑机进行吹塑，从自料斗下料，母粒向膜头方向向上剂出，利用空气吹胀，得到厚度为10μm的薄膜。按国家标准GB 13022-91检测，拉伸强度(MPa)：横向，13MPa，纵向，18MPa；断裂伸长率(％)：横向，155％，纵向170％。薄膜的透光系数为0.36。
2013年4月10日，将膜铺设在浙江义乌佛堂枇杷果园中，在2013年9月中旬调查，结果得到，薄膜90％以上面积自然破损严重，膜片大小极大多数小于20厘米，再将碎片翻入土壤中。2014年2月调查，薄膜已分解成小于1厘米的生物炭含量高于50％的小碎片，在土壤中不会对植物根系产生不良影响，相反，由于较高的生物炭含量和在碎片中活跃的微生物活动，可加速剩余塑料的分解，同时，生物炭本身具有土壤的保水保肥、提高碳汇的作用。
由于生物炭的生产存本较低，约是塑料存本的1/2。因此，在加入约30％左右生物炭后薄膜的总的生产存本可下降10％左右。
以上所述的实施例只是本发明的一种较佳的方案，并非对本发明作任何形式上的限制，在不超出权利要求所记载的技术方案的前提下还有其它的变体及改型。
