Description

一种可降解塑料瓶及其制备方法
技术领域
本发明涉及塑料材料技术领域，具体涉及一种可降解塑料瓶及其制备方法。
背景技术
塑料瓶具有强度高、质量轻、抗腐蚀、价格便宜等特点，在人们的生产生活中得到广泛应用。塑料瓶的应用在给人们带来极大方便的同时也带来严重的负面影响，大部分废弃的塑料瓶除了可在特殊条件下降解外，其在自然界环境中的光、生物降解速度非常缓慢，大概需要几百年的时间才可能完全消失，虽然其可通过掩埋、焚烧等方法来处理，但这些方法存在极大的缺陷。大量使用后的废弃塑料无法自动降解，长期残留在自然环境中可造成严重的环境污染，不仅影响生态平衡，同时也威胁着人类的健康。据不完全统计，全球每年生产的塑料瓶超过亿吨，而我国的塑料瓶占了相当大的比例，其中一次性塑料制品较多。使用后废弃的塑料瓶具有数量大、分布广、难回收等特点，形成白色垃圾，造成严重的环境污染。
为了解决这一问题，可降解塑料成为研究者们关注的热点，虽然可降解塑料的研究取得了一定成果，但可降解塑料仍然存在降解不充分等缺陷缺陷，使其应用范围受到了限制。
发明内容
本发明的目的在于针对现有技术的缺陷和不足，提供一种可降解塑料瓶及其制备方法，以解决上述背景技术中提出的问题，本发明具有一定的可降解性，使用时具有一定的抗冲击性、耐腐蚀和抗氧化，废气后在段时间内可被环境消纳，大大缓解了对环境的污染，不会对人体身心健康造成损害，该方法制备形成的塑料瓶具有一定的市场推广价值。
为实现上述目的，本发明采用以下技术方案是：它包含塑料瓶本体1、瓶盖2，所述的塑料瓶本体1顶部设置有瓶盖2且两者之间通过螺纹齿合活动连接，所述的塑料瓶本体1的底部设置有底座11，顶部设置有瓶口12，所述的塑料瓶本体1靠近底座11处设置有下弧形部13，所述的塑料瓶本体1靠近瓶口12处设置有上弧形部14，所述的底座11上等间距设置有第一加强筋15，所述的下弧形部13上等间距设置有第二加强筋16，所述的上弧形部14上等间距设置有第三加强筋17，所述的瓶口12下部与塑料瓶本体1的连接部设置有固定环18，所述的固定环18上设置有密封圈19，所述的密封圈19上安装有支撑垫20，所述的瓶盖2设置在支撑垫20的上方，所述的瓶盖2内壁设置有内螺纹，所述的瓶口12的外周设置有外螺纹，所述的瓶盖2与瓶口12通过螺纹齿合连接固定。
所述的一种可降解塑料瓶包含以下重量份数的组份：聚氯乙烯醇30-50份、聚已内酯10-20份、聚乳酸2-5份、脂肪族芳香族共聚酯2-5份、改性淀粉5-10份、纤维素2-5份、甲壳质2-3份、光敏剂20-30份，所述的光敏剂为抗氧剂1010或抗氧剂264中的一种或两种。
所述的一种可降解塑料瓶包含以下步骤方法：步骤一，按相应重量比例称取各成分的含量；步骤二，将称重后的组份进行粉碎加工；步骤三，将粉碎后的组份进行筛选处理；步骤四，将筛选后的组份采用高速混合机进行充分混合；步骤五，将混合后的组份进行造粒加工；步骤六，将形成的可降解塑料通过挤塑机挤出成型。
所述的步骤二中粉碎的目数大小为60-120目，目数大小太粗了会造成表面粗糙，手感不好，容易站脏，太细了又不经济，目数大小在粉碎过程中尤为重要。
所述的步骤三中特别是改性淀粉筛选尤为重要，颗粒较大在压延过程中高温高压下水分汽化容易产生针眼，成型后容易出现大孔，导致成品报废。
所述的步骤四中混合过程需增设预热装置与抽湿装置，因在混合过程中靠之间组份的磨擦发热效率较低，温控幅度较窄，温度的把控对成品率有一定影响，所以需要增加预热装置，针对改性淀粉混合时最重要的是控制水分，若改性淀粉一点水分都没有，塑化效果不好，水分过多的话粒料会产生气泡，混合温度一般控制在90-115℃，时间为30-150min。
所述的步骤五中造粒过程采用双螺杆挤出机，所述的双螺杆挤出机包含挤入过程、第一挤压过程、第二挤压过程、挤出过程，所述的挤入过程温度为140-170℃，第一挤压过程温度为190-200℃，第二挤压过程温度为210-220℃，挤出过程温度为105-130℃。
所述的步骤六中挤塑机温度分为八段，一段160-165℃，二段160-170℃，三段165-170℃,四段160-170℃，五段160-170℃，六段165-170℃，七段165-170℃，八段165-170℃，每端挤压时间为0.5-1s，吹气时间为2-2.5s，排气时间为1-1.5s，动作压力为0.1-1MPa，吹气压力为0.4-0.8MPa。
采用上述技术方案后，本发明有益效果为：具有一定的可降解性，使用时具有一定的抗冲击性、耐腐蚀和抗氧化，废弃后在段时间内可被环境消纳，大大缓解了对环境的污染，不会对人体身心健康造成损害，该方法制备形成的塑料瓶具有一定的市场推广价值。
