Description

生物降解环保型餐具的配方及生产工艺
本发明涉及经自然风化可降解型餐具的生产工艺。
以前，快餐餐盒、餐具等主要由泡沫塑料生产而成。这种快餐餐具在高温使用时对人体有害，且被公认为白色污染，已被禁止使用。目前有纸制快餐餐具的生产，但这种纸制快餐餐具生产工艺较复杂，成本较高。也有用塑料原料和改性淀粉生产而成的快餐餐盒，但这种快餐餐盒在生物降解方面还存在降解慢的不足。
本发明的目的是针对现有技术的不足，设计一种生产工艺较简单，成本较低，降解快的环保型餐盒的生产工艺。
本发明的目的可以通过以下技术方案实现，该发明原料是以下列重量百分比组成：淀粉20-35％、植物粉40-55％、山梨醇2-7％、聚丙烯(PP)7-13％、聚乙烯(PE)2-5％、9-13％偶联剂、甘油3-6％、光敏剂2-4％。本发明的生产工艺是：将淀粉、植物粉、山梨醇、聚丙烯(PP)、聚乙烯(PE)粉碎至70目以上，将以上物料加入甘油及光敏剂充分混合得混合物料，将混合物料在混炼机中120-150℃混炼，将混炼好的物料注入模具中定型即成产品。
本发明的生物降解环保型餐盒的配方及生产工艺成本较低、工艺简单，降解速度快。
图1为本发明的工艺流程图；
下面结合附图对本发明进一步详述：本发明的原料是以下列原料的重量百分比来组成的：植物粉40-55％，选择甘蔗渣、花生壳、干松针、谷糠、大豆壳等，用浓度0.2-1％的硫酸或盐酸浸泡2-10小时，进行脱脂处理，处理后干燥至其含水率小于10％，再将淀粉、植物粉、山梨醇2-7％、聚丙烯(PP)7-13％、聚乙烯(PE)2-5％粉碎至70目以上，加入偶联剂硅烷9-13％，甘油3-6％，光敏剂二本甲酮3％充分混合，得混合物料，将混合物料在混炼机中120-150℃混炼，将混炼好的物料注入模具中保温25-40℃，2-4小时定型即成产品。本发明的最佳配方为：25％淀粉、45％植物粉、3％的聚乙烯、7％的聚炳烯、3％的甘油10％的偶联剂、4％的山梨醇、3％的光敏剂。本发明生产的餐具，在自然界中光合作用下可4-5个月降解完毕。
