(2)将硅藻土、混晶二氧化钛加入至球磨机中,进行球磨处理后,制得成核剂;
(3)按重量份计,将180-200份低密度聚乙烯、30-40份聚乙烯蜡、1-5份抗收缩剂、3-6份抗菌醋酸酯淀粉、2-8份成核剂混合均匀后,加入至发泡机中,加热至低密度聚乙烯完全融化后,向其中加入15-20份发泡剂,发泡完成后,进行牵引定型、冷却、延展、收卷处理后,得到果实运输用EPE珍珠棉。
具体地,上述步骤(1)中,肉桂精油与甘油的质量比为1:5-8。
具体地,上述步骤(1)中,肉桂精油溶液与醋酸酯淀粉的质量比为1:15-20。
具体地,上述步骤(2)中,硅藻土与混晶二氧化钛的质量比为1:3-6。
具体地,上述步骤(2)中,球磨处理时,球磨介质为质量分数为75%的乙醇水溶液。
具体地,上述步骤(3)中,抗收缩剂为聚氧乙烯烷基醇酰胺。
由以上的技术方案可知,本发明的有益效果是:
本发明制得的EPE珍珠棉,加工性能优异,便于裁剪、加工成各种形状的包装材料,同时具有优异的透气性能和抗菌效果,极大地延长了内部水果的保存时间。其中,本发明制得的抗菌醋酸酯淀粉,无毒环保,并且在自然界中易于降解,尤其是具有优异的抗菌效果,能显著的抑制病菌在其表面繁衍生殖,进而有效的降低了包装材料内部水果被病虫害侵害的概率;同时本发明制得的抗菌醋酸酯淀粉,还能有效的提升EPE珍珠棉的白度,进而有效的提升了EPE珍珠棉包装材料的外观,提升了其品质;本发明制得的成核剂,能有效的提升EPE珍珠棉内部气泡分布的均匀性,同时能提升EPE珍珠棉的透氧性,保证包装材料内部具有一定的氧气和较高浓度的二氧化碳,使得果蔬能在包装材料内部保持较低的呼吸作用,进而有效的提升了果蔬的保鲜效果。
