Description

以聚 ¾Ji为粘结剂的农用岩棉
技术领域
[0001] 本发明属于设施农业中基础设备的研发和设计技术领域， 具体公幵以聚乳酸为 粘结剂的农用岩棉。
背景技术
[0002] 农用岩棉是无土栽培基质中无机基质的一种， 具有化学性稳定、 理性状良、 pH 稳定以及经高温消毒后不携带任何病原菌等特点。 不仅可用于蔬菜、 花卉、 苗 木的种植， 还能用于幼苗的组织培养， 农用岩棉能够为植物提供保肥、 保水、 无菌、 空气供应量充足的良好根区环境， 其材质亦可循环再利用。 但是， 目前 国内的农用岩棉生产大都以酚醛树脂为粘结剂， 这种粘结剂的生产原料主要为 苯酚和甲醛， 在生产、 使用和回收过程中， 对环境、 生产人员及接触人员都会 产生潜在的危害。
[0003] 作为粘结剂的聚乳酸原料来源于植物， 以玉米、 马铃薯等作物为原料， 通过提 取、 发酵、 提纯、 聚合等工艺制取， 资源可再生， 生产过程中基本对环境和生 产人员不产生危害。 同吋， 聚乳酸具有良好的生物相容性和生物降解性， 其降 解的最终产物为二氧化碳及水， 对人员及环境的影响甚微， 这样对农用岩棉的 回收再利用创造有利的条件。
技术问题
[0004] 本发明的目的： 设计一种新的农用岩棉配方， 主要是用聚乳酸替代酚醛树脂， 同吋， 通过聚乳酸与其它组分的合理配比形成新的农用岩棉， 这种农用岩棉表 现出优良的环境友好， 同吋， 使得农作物对于微肥的利用获得显著的提高， 从 而获得很高的经济效益。
问题的解决方案
技术解决方案
[0005] 本发明的技术方案： 以聚乳酸为粘结剂的农用岩棉， 该农用岩棉包括下述质量 配比： 玄武岩或灰绿岩 30-40份、 石灰石 10-15份、 焦炭 10-15份、 矿澄 5-10份、 聚 乳酸粘结剂 1.5-30份； 上述材料均为市售可得。
发明的有益效果
有益效果
[0006] 有益效果： 聚乳酸降解产生的 CO 2也可部分满足作物光合作用的需求， 这样可 以减少温室内 CO 2气体肥的施用量， 降低生产成本。 聚乳酸的降解吋， pH值会 下降， 大部分蔬菜作物生长适宜的土壤 pH都偏弱酸性， 所以聚乳酸在种植过程 中可作为一种 pH调节剂。 微量元素肥在作物体内含量在百万分之几到十万分之 几， 对作物的生长很重要。 目前的微肥的施用主要采取的是叶面喷雾、 浸种、 浸根等方法， 在这些方法中微肥溶液随着水含量变化， 浓度也会发生变化， 无 法控制作物的吸收量， 每次施用后作用不持续。 本发明利用聚乳酸的降解性能 ， 缓控微肥营养作用， 减少淋洗的损失， 作用于作物的整个生长周期， 提高微 肥的利用率， 控释肥目前能把肥料的利用率提高 50%左右， 低碳环保， 减少微肥 的使用量和施用次数， 降低生产成本， 获得很高的经济效益。
