Description

一种可防水的降解环保袋制备方法
技术领域
本发明涉及环保袋相关领域，具体为一种可防水的降解环保袋制备方法。
背景技术
现有的环保袋大多为塑料袋，塑料袋是人们日常生活中必不可少的物品，常被用来装其他物品。因其廉价、重量极轻、容量大、便于收纳的优点被广泛使用，但又因为塑料袋降解周期极长、处理困难的缺点而被部分国家禁止使用和生产。
目前，现有塑料袋制备方法中，为了提高塑料袋的质量，会在生产的塑料袋中增加化学增韧剂来增加塑料袋的韧性，但是过多的化学增韧剂难以降解，会对环境产生一定的影响，而且化学成分添加也有一定的副作用，会对人体产生一定的影响，严重影响了人们的生活，现有的塑料袋防水效果较差，给人们带来了许多麻烦，使用过程中，容易产生静电。
发明内容
本发明的目的在于提供一种可防水的降解环保袋制备方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种可防水的降解环保袋制备方法，其特征在于：包括以下几个步骤：
S1、选取以下重量份原料：碳酸丙烯酯30-40份、聚丙烯26-33份、聚丁二酸丁二醇酯16-23份、聚乙烯醇21-24份、碳酸钙复合粉8-12份、纳米二氧化钛17-28份和高填充复合材料14-20份，将原料混合后放入反应釜中进行搅拌，然后向反应釜中不断加入催化剂，得到混合物一；
S2、将硝化纤维素、硫化顺丁橡胶、甘油、纳米二氧化钛和羧甲基淀粉钠加入高度混合机中，然后加入抗氧化剂和植物性防水剂，进行搅拌混合，搅拌时间为30-60min，搅拌后获得防水涂料；
S3、将混合物一中加入生物基耦合剂、软化剂和渗透剂进行搅拌混合，然后放入挤出机中，在转速为55-70r/min和挤出温度为130-150℃的条件下进行造粒，得到塑料颗粒；
S4、将塑料颗粒放入吹膜机，然后向吹膜机中通入惰性气体，吹膜机的温度保持在40-55℃，然后制得塑料薄膜；
S5、将塑料薄膜两侧均匀涂抹一层防水涂料，通过热吹风机进行烘干定型，然后在防水涂料表面均匀涂有一层防静电涂料，再次通过热吹风机进行定型，即可得到塑料袋材料；
S6、将塑料袋材料放入制袋机中制作，即可得到可防水的降解环保袋。
优选的，所述步骤S1中碳酸钙复合粉包括以下重量份原料：碳酸钙19-25份、磷酸钙8-11份、增韧剂5-7份、生物质颗粒4-7份、除泡剂5-6份和氧化钙15-22份。
优选的，所述步骤S5中防静电涂料由环氧树脂、有机硅树脂、甘油、聚苯胺和成膜助剂组成，防静电涂料的厚度为0.2-0.4mm。

优选的，步骤S1中原料混合物与催化剂的重量比为34：3。
优选的，步骤S4中惰性气体通入速度为0.5-1.5m3/min，通入时间40-60min。
优选的，步骤S5中防水涂料的厚度为2-2.5mm。
与现有技术相比，本发明的有益效果是：环保袋的制备过程中，向吹膜机中通入惰性气体，可使制成的塑料薄膜厚度均匀，惰性气体能够避免气体与原料发生反应，在塑料薄膜上涂有防水涂料，为环保袋增添了防水的功能，适合人们普遍使用，防水涂料的原料中添加抗氧化剂和植物性防水剂，提高防水涂料的防水性能，延长环保袋是使用时间，涂有防静电涂料，防静电涂料中设置有成膜助剂，加快防静电涂料的定型，为防静电涂料的涂抹提供帮助，防静电涂料和防水涂料的厚度均不影响环保袋的使用。
