Description

一种长期有效的防霉包装材料
技术领域
本发明属于防霉包装材料加工技术领域，具体涉及一种长期有效的防霉包装材料。
背景技术
包装纸，主要用于包装目的的一类纸的统称。通常具有高的强度和韧性，较高的物理强度及一定的抗水性，能耐压、耐折。其细分纸种很多，各自有不同的性质和用途。包装用纸有牛皮纸、鸡皮纸、纸袋纸、羊皮纸、玻璃纸、中性包装纸、半透明纸、防锈纸、防油纸、食品包装纸等。
根据商品的特点，包装纸具有相应的特殊性能，防霉包装应用越来越广泛，例如鞋业等，随着防霉包装技术的逐步发展，用户对包装材料的要求越来越高，但通常防霉包装纸只在短时间内有效，无法重复使用，造成了一定的资源浪费。
发明内容
本发明的目的是针对现有的问题，提供了一种长期有效的防霉包装材料。
本发明是通过以下技术方案实现的：一种长期有效的防霉包装材料，包括以下重量份的原料：硫酸盐漂白针叶木浆100份、氧化铝纤维14-18份、聚丙烯腈纤维6-10份、缓释防霉剂5-7份、碳酸钙1-3份、酪素1-3份；
所述缓释防霉剂的制备方法为：将麦芽糊精、玉米淀粉与水以重量比3-7:12-18:100混合，然后在温度为65-75℃的条件下搅拌混合1-2小时，完成后调节pH值至3.8-4.2，然后加入相当于玉米淀粉重量1.2-1.8%的噻苯咪唑、2.8-3.4%的麻叶提取物，在温度为40-50℃的条件下搅拌处理30-40分钟，完成后调节pH值至中性，再加入相当于玉米淀粉重量1.5-2.5%的聚二甲基硅氧烷硅油、4-5%的氯化铜超声处理12-18分钟，完成后冷冻干燥，即得。
作为对上述方案的进一步改进，所述硫酸盐漂白针叶木浆初始打浆度为14.5°SR。
作为对上述方案的进一步改进，所述麦芽糊精、玉米淀粉与水混合时的搅拌速度为300-400转/分钟。
作为对上述方案的进一步改进，所述超声处理的频率为28-32kHz。
作为对上述方案的进一步改进，所述麻叶提取物的制备方法为：将采集的麻叶全株清洗后，加入与其等重量的水，充分捣碎后在温度为50-60℃的条件下烘干至含水量低于3%，然后加入相当于其重量3-5倍质量浓度为75-85%的乙醇溶液，在温度为75-80℃的条件下浸提30-40分钟，过滤，滤液经离心、旋蒸至膏状，即得。
本发明相比现有技术具有以下优点：本发明中通过合理制备缓释防霉剂，由于噻苯咪唑、麻叶提取物合理配比，能够实现有效增强防霉效果，缓释效果好，能够有效延长材料的防霉时效，再与其他原料合理配比，能够保证所得纸张平滑性好，具有一定的防水性和防污性，提高其使用性能。
