Description

一种可降解的注塑原料及其所使用的复合胶 技术领域
本发明涉及一种可降解的注塑原料及其所使用的复合胶, 更具体地 讲, 本发明涉及可降解的含淀粉的注塑原料及其所使用的复合胶。 背景技术
现有的可降解塑料尚存在一些缺点, 或者成本高, 或者强度差, 或 者不易降解。
2006年 05月 17 日公开的、公开号为 CN 1771784A中国发明专利申 请中公开了一种 "可自然降解的环保花盆及其制造方法", 该环保花盆 采用粉碎的植物纤维及胶粘剂制成,其中胶粘剂由氧化淀粉与聚乙烯醇 ( PVA )或聚己内酯 (PCL )、 或氨基塑料模塑粉中的一种或多种混合而 成。 通过调节氧化淀粉的用料比, 可以效地调节其强度和降解性, 找到 最佳平衡点。
但由于植物纤维本身颗粒大而且不能塑化成熔融状态, 因此在注塑 的过程中经常出现材料流动性不足的问题。普通淀粉或氧化淀粉由于本 身颗粒密度大, 比较紧凑, 与其它合成树脂配合后依然不能形成足够的 整体材料塑性, 无法克服注塑工艺所必须的材料流动性问题。 因而, 现 有技术的原料仅能适应模压加工方法, 这将导致生产时会耗费大量人 力, 自动化程度低,生产效率低, 而且产品仅为局限于某些形状的容器, 无法生产结构较为复杂的产品。 发明内容
本发明的目的是克服现有可降解材料的上述缺陷,提供一种流动性 良好的注塑原料以及其所采用的可降解的复合胶。
为实现上述发明目的,一方面,本发明提供一种可降解的注塑原料, 该注塑原料包括植物纤维粉, 其中, 以注塑原料的干重计, 该注塑原料 包括 60-80%的植物纤维粉和 20-40%的复合胶; 其中, 植物纤维粉的颗 粒大小为 20-200 目, 优选为 60-160 目, 更优选为 80-120 目; 而且, 为解决流动性问题,所采用的复合胶是由淀粉和合成树脂通过糊化工序 制得的, 以克服淀粉本身颗粒密度大、 比较紧凑的问题。
由于在本发明的注塑原料中, 淀粉经过糊化后,体积极大膨胀, 密 度大大地减小, 与合成树脂例如尿醛树脂或三聚氰胺甲醛树脂能产生较 充分的酯化反应, 所产生的复合胶密度比较小, 覆盖面比较大, 能在植 物纤维的颗粒间形成有效的胶体层, 符合注塑所需要的流动性要求。
在本发明的注塑原料中, 以注塑原料的干重计, 还可以进一步包括 0. 5-3%的润滑剂。 所采用的润滑剂可以是注塑工艺中常见的润滑剂, 如 硬脂酸盐或酯类的润滑剂, 例如硬脂酸 4弓、 硬脂酸辞、 硬脂酸镁、 单硬 脂酸甘油酯等。
在本发明的注塑原料中, 合成树脂可以为氨基树脂, 例如尿醛树脂 和 /或三聚氰胺甲醛树脂; 淀粉可以为氧化淀粉, 因为在复合胶中氧化 淀粉可产生更强的酯化交联。
在本发明的注塑原料中,植物纤维粉可选自于稻壳粉、竹粉、木粉、 椰子壳粉以及其它农作物的壳粉和茎粉, 但不限于这些植物原料。 为实现上述发明目的, 另一方面, 本发明还提供了一种可降解的复 合胶, 其中, 以复合胶的干重计, 复合胶包括 1份重的淀粉和 0. 25-4 份重的合成树脂, 其中, 复合胶是通过将合成树脂加入到糊化后的淀粉 中而制得的。
在本发明的复合胶中, 合成树脂优选为氨基树脂, 例如尿醛树脂和 /或三聚氰胺甲酸树脂; 淀粉优选为氧化淀粉。
本发明的可降解复合胶可以呈糊状。
在本发明的复合胶中, 如果包括尿醛树脂和三聚氰胺甲醛树脂, 则 二者重量比可以为 1: 0. 1-0. 6。
本发明的注塑原料可包括适量的水, 其含水量控制在湿润量, 例如 注塑原料攥在手中,不会从指缝中漏出,伸开手撑后, 又能自然散开, 既 不粘手, 又不太干。 太湿则略作烘干, 太干则加少量水略作湿润。
本发明的可降解复合胶可按以下方法制备:
1 )、 将一定重量的淀粉加入适量的热水或碱溶液, 糊化 20-60分 钟, 得糊状液体 A;
2 )、向糊状液体 A中加入相应重量的尿酸树脂和相应重量的三聚 氰胺甲酸树脂, 搅拌均匀, 即得糊状的可降解复合胶。
淀粉、 尿醛树脂和三聚氰胺甲酸树脂, 三者用量比符合前述的要 求。
本发明可降解复合胶用于注塑时的使用方法, 包括下述步骤: 1 )、 分别取 20-40 %重的前述的可降解复合胶、 58%_75%重、 过
20-200目、 优选 60-160目、 更优选 80-120目筛的植物纤维粉和 0. 5-4 %重的润滑剂, 配成均匀的混合物, 其含水量控制在湿润量;
2 )、 将步聚 1 )所得混合物加入注塑机的料桶中, 导入注塑机, 加 热成熔融状, 注射进入模具, 出模成型。 选用柱塞式传递注塑机:预热温度为 90-1 1 0 °C ,模具温度为 1 30-175 °C ,成型压力为 140-420MPa ;选用螺杆式注塑机的料桶温度为 75-90 °C , 模具温度为 140_170 °C , 成型压力最小为 24幌 Pa。
淀粉或氧化淀粉经过糊化后,体积极大膨胀, 密度大大地减小, 与 尿酸树脂、 三聚氰胺甲酸树脂中的较充分的酯化交联, 采用氧化淀粉, 酯化交联度更高。
本可降解复合胶密度比较小, 覆盖面比较大, 熔融后符合注塑所需 要的流动性要求, 能将植物纤维粉有效地粘接起来。
本发明中, 用其它氨基树脂代替尿醛树脂或其中添加其它氨基树 脂, 制备本发明可降解复合胶, 结果相似。
本发明的注塑原料相对于中国专利文献 CN 1771784A公开的配方, 可以满足注塑要求, 而使用注塑机注塑加工, 自动化程度高、 生产效率 高、 不受限于形状, 可以产品工业结构件、 生活用品、 一次性用品、 餐 具等各种产品, 而且其成本也不高, 利用本发明制成的注塑件可在艮多 场合下取代硬质塑料。 例如, 采用重量比为 1 : 0. 1-0. 6 的尿醛树脂、 三聚氰胺甲酸树脂的混合物和氧化淀粉,按照前述方法制备可降解复合 胶, 并用于注塑加工, 所得注塑件在同等形状、 尺寸下, 机械强度堪比 工程塑料, 可在多种场合替代工程塑料或金属件。 具体实施方式
