Description
技术领域
本申请涉及瓦楞纸板领域,尤其是涉及一种基于淀粉胶的抗静电瓦楞纸板及其制备方法。
背景技术
瓦楞纸板是用于生产折叠纸箱的片材,通常由多层波浪形瓦楞芯纸与瓦楞面纸交错复合而成。对于在静电场中容易出现损伤的物品,其所用包装纸箱需具有一定的抗静电性能,以防止静电荷在纸箱表面积累。
在表面涂布导电涂料是当前抗静电包装材料的主要措施,导电涂料中掺杂有较多的导电填料,例如金属、金属氧化物和炭黑、石墨等等。炭黑、石墨因其优异的耐候性、耐腐蚀性以及低廉的成本,应用最为广泛。然而纸箱表面的频繁摩擦也致使填料脱落耗损较大,抗静电性能长效性较差。
发明内容
本申请提供一种基于淀粉胶的抗静电瓦楞纸板及其制备方法,能够有效减少纸箱表面导电填料的脱落损耗,提高其抗静电性能的长效性。
第一方面,本申请提供一种基于淀粉胶的抗静电瓦楞纸板,包括波纹芯纸层和覆盖于波纹芯纸层两侧的面纸层,所述面纸层背离波纹芯纸层的一侧设置有抗静电层,所述抗静电层呈网格状设置,所述抗静电层包括如下质量份的原料:
氧化玉米淀粉:25~35份;
明胶:5~10份;
硼砂:0.5~1.2份;
烧碱:1~3份;
稳定剂:2~5份;
复合增塑剂:3~6份;
改性导电填料:4~10份;
水:130~150份;
所述改性导电填料选自炭黑、石墨中的一种或其组合物,且所述改性导电填料表面修饰有羧基。
上述技术方案,主要以氧化玉米淀粉为主要基料,其价格低廉、涂布工艺成熟且具有亲水性,能够在成膜后吸附空气中水分形成水膜,促进静电传导逸散,防止静电积累。上述氧化玉米淀粉在烧碱和硼砂作用下,能够在较低温度发生糊化交联,具有优异的粘性,能够为导电填料提供基础的附着力。与此同时,本申请通过加入明胶并对导电填料进行改性,将羧基接枝于导电填料表面,增强其反应活性,使其能够与明胶中的大量活性氨基发生酰胺化反应,或与羟基发生酯化反应,与淀粉胶基料形成化学键合,从而能够显著提高导电填料的附着力,降低在外力作用下发生脱落的概率。另外,明胶的加入能够显著提高淀粉胶的强度,改善其成膜后的拉伸强度。
优选的,所述导电填料的D50粒径为10~500nm,更优选为50~100nm。
优选的,所述改性抗静电剂的原料包括质量比为100:(3~6):(1.5~4.5)的导电填料、氨基硅烷偶联剂与丁二酸酐。
在上述技术方案中,氨基硅烷偶联剂起到架桥作用,经水解后,氨基硅烷偶联剂一端与丁二酸酐与发生酰胺化反应,另一端与导电填料表面羟基缩合,从而将羧基接枝修饰于导电填料表面,赋予其优异的化学反应活性,促进其与明胶的化学键合。
优选的,所述氨基硅烷偶联剂选自γ-氨丙基三甲氧基硅烷或γ-氨丙基三乙氧基硅烷中的至少一种。
优选的,所述氨基硅烷偶联剂与丁二酸酐的摩尔比为1:1。
优选的,所述改性抗静电剂的原料还包括苯基硅烷偶联剂,所述氨基硅烷偶联剂与苯基硅烷偶联剂的质量比为(3~6):(0.5~1.5)。
苯基硅烷偶联剂附着于导电填料表面,可利用其苯基的位阻作用抑制导电填料的团聚沉降,提高淀粉胶的稳定性。需要说明的是,其相比于烷基硅烷偶联剂,不影响羧基改性填料与明胶的化学键合,有利于减少导电天填料的脱落损耗。
优选的,所述苯基硅烷偶联剂选自苯基三甲氧基硅烷和苯基三乙氧基硅烷中的至少一种。
优选的,所述改性抗静电剂的制备方法如下:
苯基硅烷偶联剂分散于二甲基甲酰胺-水共混液中,加入导电填料,搅拌10~30min,再加入氨基硅烷偶联剂和丁二酸酐,于50~70℃下反应,反应完成后醇洗过滤,即得改性抗静电剂。
优选的,所述二甲基甲酰胺-水共混液中,二甲基甲酰胺与水的质量比为9~12:1。
优选的,所述反应时间为4~6h。
优选的,所述复合增塑剂采用质量比为4:1~2的羟乙基纤维素和聚乙二醇。
淀粉与明胶作为胶料主要基材,其成膜后柔韧性较差,不耐弯折,容易在使用过程中破裂致使导热填料脱落。为解决该问题,本申请采用了羟乙基纤维素和聚乙二醇的复配物作为增塑剂,其中羟乙基纤维素成膜后的增韧作用较为明显,而聚乙二醇能够嵌入糊化淀粉、明胶与羟乙基纤维素分子间,降低分子间氢键力等分子间作用力,起到增塑增韧效果。
优选的,所述聚乙二醇的平均分子量为300~600。
低分子量聚乙二醇渗透性能好但无法起到良好的位阻作用,对分子间作用力的降低效果较差。因此分子量适当的聚乙二醇有利于发挥更为优异的增韧效果。
优选的,所述稳定剂采用质量比为1:1~2的琼脂糖和十二烷基醚硫酸钠改性膨润土。
淀粉胶体系中,大量改性导电填料的使用导致胶料在静置中容易出现团聚沉淀现象,需要加入适量稳定剂以提高抑制沉淀物产生。本申请采用的琼脂糖是一种含有大量亲水基团的线性多聚物,能够在淀粉胶体系中形成凝胶网络,从而有效托举改性导电颗粒和未糊化的淀粉颗粒,抑制其沉降。而十二烷基醚硫酸钠改性膨润土不仅能够吸水溶胀,起到增稠抗沉降作用,还能够通过其表面的阴离子对呈负电性的氧化玉米淀粉、改性导电填料起到静电斥力作用。两者复配起到协同效果,共同抑制淀粉胶的沉降现象,提高淀粉胶的稳定性。
另外,十二烷基醚硫酸钠插入膨润土层间,能够扩大插层间距,提高其溶胀增稠作用。
优选的,所述十二烷基醚硫酸钠改性膨润土按照如下操作制得:所述十二烷基醚硫酸钠改性膨润土按照如下操作制得:将十二烷基醚硫酸钠溶于去离子水中,调节pH值至1~2,经水洗、过滤、洗涤、干燥即得。
优选的,所述膨润土的D50粒径为1~100μm,更优选为10~60μm。
优选的,所述十二烷基醚硫酸钠和膨润土的质量比为100:2~4。
第二方面,本申请提供一种基于淀粉胶的抗静电瓦楞纸板的制备方法,其特征在于,包括如下步骤:
淀粉胶制备:将明胶、复合增塑剂、稳定剂、改性导电填料和水混合,在40~60℃下分散溶解,得预混液;将预混液升温至65~75℃,加入氧化玉米淀粉和烧碱,搅拌反应1~2h,加入硼砂,继续搅拌0.5~1h,得到淀粉胶;
抗静电层成型:在面纸外侧涂布形成网格状淀粉胶,干燥后的得到抗静电层;
复合:通过瓦楞机在波纹芯纸两侧分别复合一层带有抗静电层的面纸,即得抗静电瓦楞纸板。
本申请淀粉胶的糊化温度相对较低,一方面是氧化玉米淀粉糊化温度较低;另一方面是为了防止明胶在过高温度下分子链被破坏。影响其与羧基改性导电填料的化学键合。
上述面纸外侧指面层瓦楞纸背离波纹芯纸的一侧;网格状淀粉胶可通过辊涂或网版印刷等工艺设备成型,且本申请对于网格形状大小无特殊要求,经纬交叉形成网络状即可。
复合工艺中,可根据产品需要复合多层波波纹芯纸以及瓦楞里纸,复合胶为常规淀粉胶。
综上所述,本申请具有如下有益效果:
1、本申请通过在淀粉胶中加入羧基表面改性的导电填料和明胶,有效减少导电填料的脱落损耗现象,提高瓦楞纸板看静电性能的长效性。
2、本申请通过采用氨基硅烷偶联剂、苯基硅烷偶联剂与丁二酸酐对导电填料进行改性,能够有效促进导电填料与明胶的化学键合,从而提高导热填料的在瓦楞纸板表面的附着力;同时抑制导电填料的结聚沉降现象。
3、本申请以羟乙基纤维素和聚乙二醇为复合增塑剂,能够有效提高抗静电膜层的柔韧性,减少瓦楞纸板使用过程中开裂造成的导电性能下降现象。
4、本申请以琼脂糖和十二烷基醚硫酸钠改性膨润土为稳定剂,能够有效防止改性导电填料或未糊化淀粉颗粒发生沉降现象,显著提高淀粉胶的稳定性。

性能检测试验
实验1、瓦楞纸板抗静电性能及其长效性测试
(1)抗静电性能:从上述实施例与对比例中各剪取5块直径为5cm的瓦楞纸板试样。采用织物感应式静电测试仪,在相对湿度为65±5%,温度为23±2℃的环境中,测试试样表面静电压半衰期(s),试验结果取其平均值。实验中,转盘转速为1500r/min,针形电极与试样之间放电距离为20±5mm,测试探头与试样之间的测量间距为15±5mm。
(2)长效性测试:将完成步骤1测试的瓦楞纸板试样放入温度为20℃,相对湿度为65RH%的实验室环境下,调湿48h。调湿后按照GB/T21196.2-2007中规定的的圆轨迹法,使用织物平磨仪在瓦楞纸箱试样表面摩擦箱规定次数,结束后再次测量试样表面静电压半衰期(s),并计算其摩擦前后差值,试验结果取其平均值。实验中加压物质量为395g,摩擦次数为3000次。
实验2、从上述实施例与对比例中剪取5块瓦楞纸板试样,采用纸张耐折度测定仪,将试样弯折1000次(弯折角度为135±2°),测量其弯折前后表面静电压半衰期的差值,试验结果取其平均值。
实验3、淀粉胶稳定性测试
从上述实施例与对比例制备得到的淀粉胶中量取5㎏放入玻璃瓶中作为试样,将其置于45℃的恒温箱中,静置72h,观察淀粉胶是否有沉淀产生,若有沉淀,则过滤分离出沉淀物并计算其质量。
结果分析:
1.结合实施例1~12和对比例1~2并结合表2可以看出,本申请通过在淀粉胶中加入明胶和羧基改性的导电填料一通配合,能够降低因摩擦导致的瓦楞纸板抗静电性能下降的概率,显著提高了瓦楞纸板抗静电性能的长效性。
2.结合实施例1和实施例4并结合表2可以看出,本申请通过在导电填料改性过程中加入苯基硅烷偶联剂能够有效抑制其团聚沉降的概率,提高淀粉胶的稳定性。进一步参考实施例5可知,采用烷基硅烷偶联剂替代苯基硅烷偶联剂反而会导致摩擦后抗静电性能的下降以及淀粉胶沉淀物的增加。其原因可能在于,烷基硅烷偶联剂在导电填料表面的附着,固然能够降低团聚沉淀,但同时其长链疏水基团也会影响羧基改性导电填料与明胶的化学键合,进而引发其摩擦、弯折后抗静电性能的下降,并出现沉降现象。
3.结合实施例1和实施例8~9并结合表2可以看出,本申请通过采用羟乙基纤维素和聚乙二醇作为复合增塑剂,能够显著提高淀粉胶的柔韧性和耐弯折性能,降低瓦楞纸板在使用过程中抗静电层出现开裂和脱落现象,保障其抗静电性能。
进一步结合实施例6~7可知,采用平均分子量为300~600的聚乙二醇有利于保障淀粉胶的柔韧性和耐弯折性能,从而减少瓦楞纸抗静电层在弯折时出现开裂脱落的概率。
4.结合实施例1和实施例10~12并结合表2可以看出,本申请通过采用琼脂糖和十二烷基醚硫酸钠改性膨润土的复合物作为稳定剂,有利于提高淀粉胶的稳定性,减少沉降现象。
本具体实施例仅仅是对本申请的解释,其并不是对本申请的限制,本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改,但只要在本申请的权利要求范围内都受到专利法的保护。
